Chapter 2

Server Installation

2.1 Overview

This chapter provides advice and instructions for mounting your system in a server rack. If your system is not already fully integrated with processors, system memory etc., refer to Chapter 3 for details on installing those specific components.

Caution: Electrostatic Discharge (ESD) can damage electronic components. To prevent such damage to PCBs (printed circuit boards), it is important to use a grounded wrist strap, handle all PCBs by their edges and keep them in anti-static bags when not in use.

2.2 Preparing for Setup

The box in which the system was shipped should include the rackmount hardware needed to install it into the rack. Please read this section in its entirety before you begin the installation.

Choosing a Setup Location

• The system should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated.
• Leave enough clearance in front of the rack so that you can open the front door completely (\~25 inches) and approximately 30 inches of clearance in the back of the rack to allow sufficient space for airflow and access when servicing.
• This product should be installed only in a Restricted Access Location (dedicated equipment rooms, service closets, etc.).
• This product is not suitable for use with visual display workplace devices according to §2 of the German Ordinance for Work with Visual Display Units.

Rack Precautions

- Ensure that the leveling jacks on the bottom of the rack are extended to the floor so that the full weight of the rack rests on them.

• In single rack installations, stabilizers should be attached to the rack. In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a server or other component from the rack.
• You should extend only one server or component at a time - extending two or more simultaneously may cause the rack to become unstable.

Server Precautions

• Review the electrical and general safety precautions in Appendix B.
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components at the bottom of the rack first and then work your way up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges and voltage spikes and to keep your system operating in case of a power failure.
• Allow any drives and power supply modules to cool before touching them.
• When not servicing, always keep the front door of the rack and all covers/panels on the servers closed to maintain proper cooling.

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the room's ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature (TMRA).

Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connections other than the direct connections to the branch circuit (i.e. the use of power strips, etc.).

Workstation Precautions

• Ensure that the caster wheels on the workstation are locked.
• Review the electrical and general safety precautions in Appendix B.
• Use a regulating uninterruptible power supply (UPS) to protect the workstation from power surges, voltage spikes and to keep your system operating in case of a power failure.
• Allow the power supply units and hot-swap SATA drives to cool before touching them.
• To maintain proper cooling, always keep all chassis panels closed and all SATA carriers installed when not being serviced.

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Slide rail mounted equipment is not to be used as a shelf or a work space.

Warning: Do not pick up the server with the front handles. They are designed to pull the system from a rack only.

2.3 Preparing the Chassis

The chassis top tower cover and feet must be removed before rack installation.

Removing the Top Tower Cover

1. Locate the blue cover lock at the rear of the cover.
2. Slide the lock to the right and push the cover forward.
3. Lift the top cover off the chassis.

Figure 2-1. Removing the Top Tower Cover and Feet

Removing the Chassis Feet

1. Lay the chassis on its side.
2. Remove the screws holding the chassis feet in place.
3. Each foot has a foot lock tab at the center. Use a flat head screwdriver to gently lift the foot lock upward. Slide the foot toward the rear of the chassis.

2.4 Installing the Rails

This section provides a guideline for installing the rails to the chassis and to the rack with the included rackmount kit.

Identifying the Sections of the Rack Rails

The optional rackmount kit includes two rack rail assemblies. Figures 2-2 and 2-3 show the sections of one rail assembly from two different angles.

Figure 2-2. Rack Rail Sections (Outer View)

Figure 2-3. Rack Rail Sections (Inner View)

Assembling the Outer Rails and the Rack Brackets

Each outer rail requires assembly with the rack brackets before mounting onto the rack.

1. Identify the two long brackets for the rear of each rail and the two short brackets for the front of each rail. The brackets are also left and right specific.
2. Secure the short bracket onto the outer rail with screws at the side as shown below.
3. Place the long bracket onto the outer rail at the approximate position to fit your rack. Use two or three screws. Leave the screws just loose enough for the bracket to slide back and forth slightly.

Note: The short bracket is secured firmly to the rail. However, the long bracket is slightly loose.

Figure 2-4. Assembling the Outer Rails

Releasing the Inner Rail from the Outer Rail

1. Locate the rail assembly.
2. Extend the rail assembly by pulling it outward.
3. Press the quick-release tab.
4. Separate the inner rail from the outer rail assembly.

Figure 2-5. Releasing the Inner Rail (Outer View)

Installing the Inner Rails to the Chassis

1. Attach the handles to the front of the chassis with three screws each.
2. Identify the left and right inner rails. They are labeled on the rails and in the figure below.
3. Align each rail with the screw holes along the side of the chassis.

Isometric line drawing of a server rack with front panel and overhead racks (no text or symbols)

Figure 2-11. Securing the Server to the Rack

Note: Figure is for illustrative purposes only. Always install servers to the bottom of a rack first.

Warning: Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

When initially installing the server to a rack, test that the rail locking tabs engage to prevent the server from being overextended. Have a rack lift in place as a precaution in case the test fails.

Removing the Chassis from the Rack

Caution! It is dangerous for a single person to off-load the heavy chassis from the rack without assistance. Be sure to have sufficient assistance supporting the chassis when removing it from the rack. Use a lift.

1. Remove the screws that hold the front of the server to the rack.
2. Pull the chassis forward out the front of the rack until it stops.
3. Find the quick-release tab on each side of the chassis on the inner rails. Press down on the quick-release tab and continue to pull the chassis out of the rack.

Warning: In any instance of pulling the system from the rack, always use a rack lift and follow all associated safety precautions.

Slide rail mounted equipment is not to be used as a shelf or a work space.

2.6 Control Panel Orientation

The server can be configured for either tower or server rack orientation. It is shipped in tower mode and can be immediately used as a desktop server. To use it in a rack, rotate the module that contains the control panel and the three drive trays (1 in Figure 2-8) 90 degrees.

Note that two of the 5.25" drives may be replaced by a mobile rack containing eight 2.5" storage drives.

Figure 2-12. Chassis in Tower Mode (Default Configuration)

3.3 Motherboard Components

Processor and Heatsink Installation

Intel® Xeon® Scalable Processors come in two models: Fabric (F model) and Non-Fabric (Non-F model). Only the Non-Fabric model is supported for this system.

The processor (CPU) and heatsink should be assembled together first to form the processor heatsink module (PHM), and then install the PHM into the CPU socket.

Caution: Use ESD protection. Do not touch the underside of the CPU. Improper installation or socket misalignment can cause serious damage to the CPU or socket which may require manufacturer repairs.

Notes:

• All power should be off, as described in Section 3.1, before installing the processors.
• When handling the processor package, avoid placing direct pressure on the label area of the CPU or socket.
• Check that the plastic socket dust cover is in place and none of the socket pins are bent—otherwise, contact your retailer.
  • Refer to the Supermicro website for updates on CPU support.
• Graphics in this manual are for illustration. Your components may look slightly different.

Assembling the Processor Heatsink Module (PHM)

After creating the processor package assembly, mount it onto the heatsink to create the processor heatsink module (PHM).

1. On the heatsink label, locate "1" and the corner next to it. Turn the heatsink upside down with the thermal grease side facing up, keeping track of the "1" corner.
2. Remove the protective thermal film if present. If this is a new heatsink, the necessary thermal grease has been pre-applied in the factory. If the heatsink is not new, apply the proper amount of the thermal grease.

3. In the plastic processor clip, locate the hollow triangle at the corner ("a" in the drawing below) next to a hole and plastic mounting clips. There is a similar hole and mounting clips at the diagonal corner of the of the processor clip ("b" in the drawing).

4. With the underside of heatsink and the underside of the processor package facing up, align the "1" corner on the heatsink ("A" in the drawing) against the mounting clips next to the hollow triangle ("a") on the processor package.

5. Also align the corner ("B") at the diagonal side of the heatsink with the corresponding clips on the processor package ("b").

6. Once aligned, press the processor package assembly onto the heatsink until the mounting clips (at a, b, c, and d) snap into place.

The processor heatsink module is assembled.

Figure 3-5. Assembling the Processor Heatsink Module

Note: The heatsink displayed may be different than the one used in the 5049A-T.

Removing the Dust Cover from the CPU Socket

Remove the dust cover from the CPU socket, exposing the socket pins as shown below. Caution: Do not touch the socket pins.

Figure 3-6. Removing the Socket Dust Cover

Installing the Processor Heatsink Module (PHM)

1. Locate the triangle (pin 1) on the CPU socket. Also locate the pin 1 corner of the PHM that is closest to "1" on the heatsink label. To confirm, look at the underside of the PHM and note the hollow triangle in the processor clip and printed triangle on the CPU located next to a screw at the corner.

2. Align the pin 1 corner of the PHM over the pin 1 corner on the CPU socket.

3. Align the two holes at diagonal corners of the PHM onto the two guide posts on the socket bracket and carefully lower the PHM onto the socket.

4. Use a T30 Torx-bit screwdriver to install four screws into the mounting holes on the socket to securely attach the PHM onto the motherboard in the sequence of 1, 2, 3, and 4, as marked on the heatsink label. Gradually tighten each to assure even pressure.

Note: Use only 12 foot-pounds of torque when tightening the screws to avoid damaging the processor or the socket.

Figure 3-7. Installing the Processor Heatsink Module

Removing the Processor Heatsink Module from the Motherboard

Before removing the processor heatsink module (PHM), power down as described in Section 3.1.

1. Using a T30 Torx-bit screwdriver, loosen and remove the screws on the PHM from the socket, starting with the screw marked #4, in the sequence of 4, 3, 2, 1.

2. Pull up the PHM while releasing the small snap tabs on two corners of the socket.

Memory Support

The X11SPA-TF supports up to 768GB of ECC RDIMM, 3TB of 3DS RDIMM, 1.5TB of LRDIMM, and 3TB of 3DS LRDIMM DDR4 (288-pin) ECC memory with speeds of up to 2933MHz in twelve memory slots. (1DPC and 2DPC are recommended for memory installation. Only selected 2^nd Gen Xeon® Scalable Processors support Intel® DC Persistent memory.)

Memory Population Guidelines

• All DIMMs must be DDR4.
- Balance memory. Using unbalanced memory topology, such as populating two DIMMs in one channel while populating one DIMM in another channel, reduces performance. It is not recommended for Supermicro systems.
Guidelines Regarding Mixing DIMMs
- Populating slots with a pair of DIMM modules of the same type and size results in interleaved memory, which improves memory performance.
- If mixing DIMMs of different speeds, all DIMMs will run at the speed of the slowest DIMM.
- x4 and x8 DIMMs can be mixed in the same channel.
- Mixing of LRDIMMs and RDIMMs is not allowed in the same channel, across different channels, and across different sockets.
- Mixing of non-3DS and 3DS LRDIMM is not allowed in the same channel, across different channels, and across different sockets.

DIMM Construction

• RDIMM (non-3DS) Raw Cards: A/B (2Rx4), C (1Rx4), D (1Rx8), E (2Rx8)
  • 3DS RDIMM Raw Cards: A/B (4Rx4)
  • LRDIMM (non-3DS) Raw Cards: D/E (4Rx4)
  • 3DS LRDIMM Raw Cards: A/B (8Rx4)

Memory Population Sequence

Blue slots versus gray slot: Install the first DIMM in the blue memory slot, which is the first of a memory channel. Then, if using two DIMMs per channel, install the second DIMM in the gray slot.

The following memory population sequence table was created based on guidelines provided by Intel to support Supermicro motherboards. The diagram is for illustrative purposes; your motherboard may look different.

Installing Memory

To install memory, first decide on the number of DIMMs to install. Refer to Table 3-1 for the sequence of DIMM population for the desired number of DIMMs. Populate the DIMM slots according to the sequence listed in Table 3-1.

ESD Precautions

Electrostatic Discharge (ESD) can damage electronic components including memory modules. To avoid damaging DIMM modules, it is important to handle them carefully. The following measures are generally sufficient.

• Use a grounded wrist strap designed to prevent static discharge.
• Handle the memory module by its edges only.
• Put the memory modules into the antistatic bags when not in use.

Installing Memory

Begin by removing power from the system as described in Section 3.1. Follow the memory population sequence in the table above.

1. Push the release tabs outwards on both ends of the DIMM slot to unlock it.
2. Align the key of the DIMM with the receptive point on the memory slot and with your thumbs on both ends of the module, press it straight down into the slot until the module snaps into place.
3. Press the release tabs to the locked position to secure the DIMM module into the slot.

Figure 3-10. Installing DIMMs

PCI Expansion Card Installation

The 5049A-T can accommodate standard size add-on cards populated in all slots on the X11SPA-TF serverboard.

Installing PCI Expansion Cards

Begin by removing power from the system as described in Section 3.1.

1. Begin by removing the PCI slot shield for the slot you wish to populate.
2. Fully seat the card into the card slot, pushing down with your thumbs evenly on both sides of the card.
3. Finish by using a screw to secure the top of the card shield to the chassis. The PCI slot shields protect the serverboard and its components from EMI and aid in proper ventilation, so make sure there is always a shield covering each unused slot.

Motherboard Battery

The motherboard uses non-volatile memory to retain system information when system power is removed. This memory is powered by a lithium battery residing on the motherboard.

Replacing the Battery

Begin by removing power from the system as described in Section 3.1.

1. Push aside the small clamp that covers the edge of the battery. When the battery is released, lift it out of the holder.
2. To insert a new battery, slide one edge under the lip of the holder with the positive (+) side facing up. Then push the other side down until the clamp snaps over it.

Note: Handle used batteries carefully. Do not damage the battery in any way; a damaged battery may release hazardous materials into the environment. Do not discard a used battery in the garbage or a public landfill. Please comply with the regulations set up by your local hazardous waste management agency to dispose of your used battery properly.

Figure 3-11. Installing the Onboard Battery

3.4 Chassis Components

Hard Drives

A total of eight SATA drives may be housed in the SC743AC-1200B-SQ chassis. The drive IDs are preconfigured as 0 through 7 in order from bottom to top (or from left to right if rackmounted).

The drives are mounted in drive carriers to simplify their installation and removal from the chassis. (Both procedures may be done without removing power from the system.)

Removing a Hot-Swap Drive Carrier

1. Open the front bezel then push the release button located beside the drive LEDs.
2. Swing the handle fully out and then use it to pull the unit straight out.

Note: Your operating system must have RAID support to enable the hot-swap capability of the SATA drives.

Mounting a Drive in a Drive Carrier

The SATA drive carriers help to promote proper airflow for the system. For this reason, even carriers without SATA drives must remain in the chassis.

1. To add a new drive, install it into the carrier with the printed circuit board side facing down so that the mounting holes align with those in the carrier.
2. Secure the drive to the carrier with the screws provided, then push the carrier completely into the drive bay. You should hear a *click* when the drive is fully inserted. This indicates that the carrier has been fully seated and connected to the midplane, which automatically makes the power and logic connections to the hard drive.

Removing a Drive from a Drive Carrier

1. Remove the screws that secure the hard drive to the carrier and separate the hard drive from the carrier.
2. Replace the carrier back into the drive bay.

Figure 3-13. Mounting a Drive in a Carrier

Note: Enterprise level hard disk drives are recommended for use in Supermicro chassis and servers. For information on recommended HDDs, visit the Supermicro website at http://www.supermicro.com/products/nfo/storage.cfm

SATA Backplane

The SATA drives plug into a drive backplane. A data cable for each drive and two LED cables need to be connected from the serverboard to the appropriate connectors on the backplane. Note that you cannot cascade the SATA backplane.

Installing Components in the 5.25" Drive Bays

The 5049A-T has two 5.25" drive bays. Components such as an extra DVD-ROM drive can be installed into these 5.25" drive bays.

Removing the Empty Drive Bay

1. First power down the system.
2. Remove the top/left chassis cover to access the drive components.
3. With the cover off, remove the screws that secure the drive carrier to the chassis (one side only) then push the entire empty drive carrier out from the back.

Adding a DVD-ROM Drive

1. Remove the guide plates (one on each side) from the empty drive carrier and screw them into both sides of the DVD-ROM drive using the holes provided.
2. Slide the DVD-ROM into the bay and secure it to the chassis with the drive carrier screws you first removed.
3. Attach the power and data cables to the drive.
4. Replace the top/left chassis cover and restore power to the system.

System Fans

The SuperWorkstation 5049A-T includes two mid-chassis fans, one rear exhaust fan, and two power supply fans. All fans are low-noise and operate in "Whisper-Quiet" mode (\~28 dB). None of the fans are hot-swappable.

Replacing Mid-Chassis and Rear Exhaust Fans

Identify the Failed Fan

1. Determine from the front control panel Fan Fail LED if a mid-chassis or rear exhaust fan has failed.
2. Use the IPMI to determine the number of fans that have failed.

4.4 Jumpers

Explanation of Jumpers

To modify the operation of the motherboard, jumpers are used to choose between optional settings. Jumpers create shorts between two pins to change the function associated with it. Pin 1 is identified with a square solder pad on the printed circuit board. See the motherboard layout page for jumper locations.

Note: On a two-pin jumper, "Closed" means the jumper is on both pins and "Open" indicates the jumper is either on only one pin or has been completely removed.

CMOS Clear

JBT1 is used to clear CMOS, which will also clear any passwords. Instead of pins, this jumper consists of contact pads to prevent accidentally clearing the contents of CMOS.

To Clear CMOS

1. First power down the system and unplug the power cord.
2. Remove the cover of the chassis to access the motherboard.
3. Remove the onboard battery from the motherboard.
4. Short the CMOS pads with a metal object such as a small screwdriver for at least four seconds.
5. Remove the screwdriver (or shorting device).
6. Replace the cover, reconnect the power cord and power on the system.

Notes: Clearing CMOS will also clear all passwords.

Do not use the PW_ON connector to clear CMOS.

UEFI BIOS

6.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the motherboard. The BIOS is stored on a chip and can be easily upgraded using a flash program.

Note: Due to periodic changes to the BIOS, some settings may have been added or deleted and might not yet be recorded in this manual. Please refer to the Manual Download area of our website for any changes to the BIOS that may not be reflected in this manual.

Starting the Setup Utility

To enter the BIOS Setup Utility, hit the key while the system is booting-up. (In most cases, the key is used to invoke the BIOS setup screen. There are a few cases when other keys are used, such as , , etc.) Each main BIOS menu option is described in this manual.

The Main BIOS screen has two main frames. The left frame displays all the options that can be configured. "Grayed-out" options cannot be configured. The right frame displays the key legend. Above the key legend is an area reserved for a text message. When an option is selected in the left frame, it is highlighted in white. Often a text message will accompany it. (Note that the BIOS has default text messages built in. We retain the option to include, omit, or change any of these text messages.) Settings printed in Bold are the default values.

A "▶" indicates a submenu. Highlighting such an item and pressing the key will open the list of settings within that submenu.

The BIOS setup utility uses a key-based navigation system called hot keys. Most of these hot keys (, , , , , keys, etc.) can be used at any time during the setup navigation process.

6.2 Main Setup

When you first enter the AMI BIOS setup utility, you will enter the Main setup screen. You can always return to the Main setup screen by selecting the Main tab on the top of the screen. The Main BIOS setup screen is shown below and the following features will be displayed:

System Date/System Time

Use this feature to change the system date and time. Highlight System Date or System Time using the arrow keys. Enter new values using the keyboard. Press the key or the arrow keys to move between fields. The date must be entered in MM/DD/YYYY format. The time is entered in HH:MM:SS format.

Note: The time is in the 24-hour format. For example, 5:30 P.M. appears as 17:30:00. The date's default value is the BIOS build date after RTC reset.

Appendix A

BIOS Codes

A.1 BIOS Error POST (Beep) Codes

During the POST (Power-On Self-Test) routines, which are performed each time the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue the boot-up process. The error messages normally appear on the screen.

Fatal errors are those which will not allow the system to continue the boot-up procedure. If a fatal error occurs, you should consult with your system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of audible beeps. The table below lists some common errors and their corresponding beep codes encountered by users.

BIOS Beep (POST) Codes
Beep Code Error	Message Description
1 beep Refresh Circuits have been reset (Ready to power up)
5 short, 1 long Memory error No memory detected in system
5 short Display memory read/write error Video adapter missing or with faulty memory
1 long continuous System OH System overheat condition

A.2 Additional BIOS POST Codes

The AMI BIOS supplies additional checkpoint codes, which are documented online at http://www.supermicro.com/support/manuals/ ("AMI BIOS POST Codes User's Guide").

When BIOS performs the Power On Self Test, it writes checkpoint codes to I/O port 0080h. If the computer cannot complete the boot process, a diagnostic card can be attached to the computer to read I/O port 0080h (Supermicro p/n AOC-LPC80-20).

For information on AMI updates, please refer to http://www.ami.com/products/.

Appendix D

UEFI BIOS Recovery

Warning: Do not upgrade the BIOS unless your system has a BIOS-related issue. Flashing the wrong BIOS can cause irreparable damage to the system. In no event shall Supermicro be liable for direct, indirect, special, incidental, or consequential damages arising from a BIOS update. If you need to update the BIOS, do not shut down or reset the system while the BIOS is updating to avoid possible boot failure.

D.1 Overview

The Unified Extensible Firmware Interface (UEFI) provides a software-based interface between the operating system and the platform firmware in the pre-boot environment. The UEFI specification supports an architecture-independent mechanism that will allow the UEFI OS loader stored in an add-on card to boot the system. The UEFI offers clean, hands-off management to a computer during system boot.

D.2 Recovering the UEFI BIOS Image

A UEFI BIOS flash chip consists of a recovery BIOS block and a main BIOS block (a main BIOS image). The boot block contains critical BIOS codes, including memory detection and recovery codes for the user to flash a new BIOS image if the original main BIOS image is corrupted. When the system power is first turned on, the boot block codes execute first. Once this process is completed, the main BIOS code will continue with system initialization and the remaining POST (Power-On Self-Test) routines.

Note 1: Follow the BIOS recovery instructions below for BIOS recovery when the main BIOS boot crashes.

Note 2: When the BIOS boot block crashes, you will need to follow the procedures to make a Returned Merchandise Authorization (RMA) request. Also, you may use the Supermicro Update Manager (SUM) Out-of-Band (OOB) (https://www.supermicro.com.tw/products/nfo/SMS_SUM.cfm) to reflash the BIOS.

D.3 Recovering the BIOS Block with a USB Device

This feature allows the user to recover a BIOS image using a USB-attached device without additional utilities used. A USB flash device such as a USB Flash Drive, or a USB CD/DVD ROM/RW device can be used for this purpose. However, a USB Hard Disk drive cannot be used for BIOS recovery at this time.

The file system supported by UEFI is FAT (including FAT12, FAT16, and FAT32) which is installed on a bootable or non-bootable USB-attached device. However, the BIOS might need several minutes to locate the SUPER.ROM file if the media size becomes too large due to the huge volumes of folders and files stored in the device.

To perform UEFI BIOS recovery using a USB-attached device, follow the instructions below.

1. Using a different machine, copy the "Super.ROM" binary image file into the disc Root "\" directory of a USB device or a writable CD/DVD.

Note: If you cannot locate the "Super.ROM" file in your driver disk, visit our website at www.supermicro.com to download the BIOS image into a USB flash device and rename it "Super.ROM" for BIOS recovery use.

1. Insert the USB device that contains the new BIOS image ("Super.ROM") into your USB drive and power on the system
2. While powering on the system, please keep pressing and simultaneously on your keyboard until the following screen (or a screen similar to the one below) displays.

Warning: Please stop pressing the and keys immediately when you see the screen (or a similar screen) below; otherwise, it will trigger a system reboot.

Note: On the other hand, if the following screen displays, please load the "Super. ROM" file to the root folder and connect this folder to the system. (You can do so by inserting a USB device that contains the new "Super.ROM" image to your machine for BIOS recovery.)

1. After locating the new BIOS binary image, the system will enter the BIOS Recovery menu as shown below.

Note: At this point, you may decide if you want to start the BIOS recovery. If you decide to proceed with BIOS recovery, follow the procedures below.

1. When the screen as shown above displays, use the arrow keys to select the item "Proceed with flash update" and press the key. You will see the BIOS recovery progress as shown in the screen below.

Note: Do not interrupt the BIOS flashing process until it has completed.

1. After the BIOS recovery process is completed, press any key to reboot the system.

1. Using a different system, extract the BIOS package into a USB flash drive.
2. Press continuously during system boot to enter the BIOS setup utility. From the top of the tool bar, click on Boot and press to enter the submenu. From the submenu list, select Boot Option #1 as shown below. Then, boot Option #1 to [UEFI AP:UEFI: Built-in EFI Shell]. Press to save the settings and exit the BIOS setup utility.

1. When the UEFI Shell prompt appears, type fs# to change the device directory path. Go to the directory that contains the BIOS package you extracted earlier from Step 7. Enter flash.nsh BIOSname.### at the prompt to start the BIOS update process.

Note: Do not interrupt this process until the BIOS flashing is complete.

1. The screen above indicates that the BIOS update process is completed. When you see the screen above, unplug the AC power cable from the power supply, clear CMOS, and plug the AC power cable in the power supply again to power on the system.

1. Press continuously to enter the BIOS setup utility.
2. Press to load the default settings.
3. After loading the default settings, press to save the settings and exit the BIOS setup utility.
