Chapter 2

Installation and Setup

This chapter provides instructions on installing and replacing main system components. To prevent compatibility issues, only use components that match the specifications or part numbers.

Up to twenty blade modules may be installed into a blade enclosure, depending upon your enclosure and blade. Blade modules with Windows and Linux operating systems may be mixed together in the same blade enclosure.

2.1 Unpacking the System

Inspect the box the system was shipped in and note if it was damaged in any way. If any equipment appears damaged, please file a damage claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold the enclosure. It should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. It will also require a grounded AC power outlet nearby. Be sure to read the precautions and considerations noted in Appendix B.

2.2 Installing or Removing the Blade Unit

Installing a Blade Unit into the Enclosure

Make sure the cover of the blade unit is on before insertion.

Installing a Blade Unit into the Enclosure

1. Pull open the blade locking handle and slowly push the blade into its bay as pictured below.
2. When the blade stops, push the handle into its locked position, making sure the notch in the handle catches the lip of the enclosure.

Caution: Insert the blade carefully to avoid damaging the connectors in the enclosure bay.

Figure 2-1. Installing the a Blade into the Enclosure

Removing a Blade Unit from the Enclosure

A blade can be removed from the enclosure while other blades continue to operate.

Removing a Blade Unit from the Enclosure

1. Power down the blade unit.

2. Lift the handle completely and use it to pull the blade unit from the enclosure.

Removing or Replacing the Blade Cover

The blade cover can be removed to access the mainboard and install processors, memory modules, the onboard battery, etc.

• To remove the cover, after removing the blade module from the enclosure, push the cover toward the rear of the blade unit. When it stops, lift the cover off the blade unit.
• To replace the cover, fit the six grooves in the cover into the studs in the sides of the blade, then slide the cover toward the front of the blade to lock it into place.

2.3 Powering Up or Down

Powering Up a Blade Unit

Each blade unit may be powered on and off independently from the rest of the blades installed in the same enclosure. A blade unit may be powered up in two ways:

• Press the power button on the blade unit.
• Use IPMIView or the web-browser based management utility to apply power using either a CMM module, or by the use of the onboard BMC chip in the blade module.

Powering Down a Blade Unit

A blade unit may be powered down in any of the following ways:

• Press the power button on the blade unit.
• Use IPMIView or the web-browser based management utility to power down; requires Operator or Admin privileges on the CMM.
• Use SMCIPMItool when connected to the CMM to power down; requires Operator or Admin privileges on the CMM.
• Use IPMIview or a browser connected to the onboard BMC chip to power down.
• Use SMCIPMItool to use a Command Line Interface to the onboard BMC chip; requires Operator or Admin privileges.

2.4 Installing the Processor and Heatsink

Cautions:

• When handling the processor (CPU) package, avoid placing direct pressure on the label area of the CPU or CPU socket.
• Improper CPU installation or socket misalignment can cause serious damage to the CPU or motherboard which may result in RMA repairs.
• Take all standard precautions to avoid electrostatic discharge (ESD) which can damage components.

Assemble the processor (CPU) and heatsink together first then install that assembly onto the CPU socket.

Notes:

• The motherboard should be installed into the chassis first and the processor should be installed into the CPU socket before you install a CPU heatsink.
• If you bought a CPU separately, use a certified multi-directional heatsink only.
• When receiving a motherboard without a processor pre-installed, make sure that the plastic CPU socket cap is in place and none of the socket pins are bent; otherwise, contact your retailer immediately.
  • Refer to the SuperMicro web site for updates on CPU support.

Installing the Processor and Heatsink

Begin by removing power from the system as described in Section 2.3.

1. Use a Torx T20 driver to loosen the screws holding down Force Frame in the sequence of 3-2-1. The screws are numbered on the Force Frame next to each screw hole. Tighten to 16.1 kgf-cm (14 lbf-in) of torque.

Screw #3 Screw #2 Force Frame Screw #1

Figure 2-3. Removing the Processor Force Frame

1. The spring-loaded Force Frame will raise up after the last screw (#1) is removed. Gently allow it to lift up to its stopping position.

Line drawing of a hand pressing down on a computer processor casing with an arrow indicating the process (no text or symbols present)

Figure 2-4. Raising the Force Frame

1. Lift the Rail Frame up by gripping the lift tabs near the front end of the rail frame. While keeping a secure grip of the Rail Frame, lift it to a position so you can do the next step of removing the External Cap.

Note: The Rail Frame is spring loaded, so keep a secure grip on it as you lift it so it does not snap up.

Rail Frame PnP Cover Cap

Figure 2-5. Lifting the Rail Frame

1. Remove the External Cap from the Rail Frame by pulling it upwards through the rail guides on the Rail Frame.

External Cap PnP Cover Cap

Figure 2-6. Removing the External Cap

1. The CPU Package is shipped from the factory with the blue Carrier Frame pre-assembled. Grip the handle of the Carrier Frame/CPU Package assembly from its shipping tray, and while gripping the handle, align the flanges of the Carrier Frame onto the rails of the Rail Frame so its pins will be at the bottom when the Rail Frame is lowered later.

2. Slide the Carrier Frame/CPU Package downwards to the bottom of the Rail Frame. Ensure the flanges are secure on the rails as you lower it downwards.

Carrier Frame/ CPU Package

Figure 2-7. Inserting the Carrier Frame/CPU Package

Note: You can only install the CPU inside the socket in one direction with the handle at the top. Make sure that it is properly inserted into the CPU socket before closing the Rail Frame plate. If it doesn't close properly, do not force it as it may damage your CPU. Instead, open the Rail Frame plate again, and double-check that the CPU is aligned properly.

1. Lift up the Rail Frame till it securely rests in upright position. Then remove the PnP Cover Cap from the CPU socket below. Grip the two lift tabs marked "Remove" at the middle of the cap and pull vertically upwards to remove the PnP Cover Cap.
   Caution: The exposed socket contacts are extremely vulnerable and can be damaged easily. Do not touch or drop objects onto the contacts and be careful removing the PnP Cover Cap and when placing the Rail Frame over the socket.
2. Gently lower the Rail Frame down onto the socket until the latches on the Rail Frame engage with the Socket housing. and it rests in place. Do not force it into place!
3. Gently lower the Force Frame down onto the Rail Frame and hold it in place until it is seated in the Socket housing. Note that the Force Frame is spring loaded and has to be held in place before it is secured.

Figure 2-12. Securing the Heatsink

The processor and heatsink installation is complete. Repeat this procedure for any remaining CPU sockets on the motherboard.

Removing a Heatsink

We do not recommend removing the heatsink. If necessary, please follow the instructions below to prevent damage to the CPU or the CPU socket.

Note: Wait for the heatsink to cool down before removing it.

1. Unscrew and remove the heatsink screws from the motherboard in the sequence as show in the figure above.
2. Hold and gently pivot the heatsink back and forth to loosen it from the CPU. (Do not use excessive force when dislodging the heatsink!)
3. Once the heatsink is loose, remove it from the CPU.
4. Clean the surface of the CPU and the heatsink to get rid of the old thermal grease. Reapply the proper amount of thermal grease to the surface before you re-install the heatsink.

2.5 Memory

2.8 Driver Installation

The Supermicro website contains drivers and utilities for your system at https://www.supermicro.com/wftp/driver. Some of these must be installed, such as the chipset driver.

After accessing the website, go into the CDR_Images (in the parent directory of the above link) and locate the ISO file for your motherboard. Download this file to a USB flash drive or save as an ISO file on local storage. (You may also use a utility to extract the ISO file if preferred.) Then mount with virtual media at BMC console redirect with USB or ISO file to install.

Another option is to go to the Supermicro website at http://www.supermicro.com/products/. Find the product page for your motherboard, and "Download the Latest Drivers and Utilities". Mount with virtual media and the screenshot shown below should appear.

Note: Click the icons showing a hand writing on paper to view the readme files for each item. Click the computer icons to the right of these items to install each item (from top to the bottom) one at a time. After installing each item, you must re-boot the system before moving on to the next item on the list. The bottom icon with a CD on it allows you to view the entire contents.

2.9 Installing the Operating System

An operating system (OS) must be installed on each blade module. Blades with Microsoft Windows OS and blades with Linux OS can operate within the same blade enclosure. Refer to the SuperMicro web site for a list of supported operating systems.

Installing by using PXE Boot

Preboot Execution Environment (PXE) is used to boot a computer over a network. To install the OS using PXE, the following conditions must be met:

• The PXE BOOT option in BIOS must be enabled.
• A PXE server has been configured; this can be another blade in the system.
• The PXE server must be connected over a network to the blade to be booted.
• The blade has only non-partitioned/unformatted hard drives installed and no bootable devices attached to it.

Once these conditions are met, make sure the PXE server is running. Then turn on the blade on which you wish to install the OS. The BIOS in the blade will look at all bootable devices and finding none, will connect to the PXE server to begin the boot/install.

Installing by using Virtual Media (Drive Redirection)

You can install the OS via Virtual Media through either the IPMIview (Java-based client utility), SuperBladeTool or the Web-based Management Utility. With this method, the OS is installed from an ISO image that resides on another system.

Refer to the manuals on the SuperMicro web site for further details on the Virtual Media (CD-ROM or Drive Redirection) sections of these two utility programs.

Linux Installation with Two Storage Drives—Note

When installing Linux with two storage drives on the SBA-4119S-T2N you may encounter a situation where one drive is recognized as HDA and the other drive is recognized as SDA. This is normal since in this case the connection for SATA HDDs is from two different controllers.

Under Native IDE mode (which is the default), your Linux OS will see one drive as HDA and the other as SDA. If the SATA controller mode operation is changed to AMD_AHCI in the BIOS, then the HDDs will appear as SDA and SDB.

2.10 Configuring RAID

For RAID setup, see http://www.supermicro.com/support/manuals/ under RAID Installation Guides.

UEFI BIOS

5.1 Introduction

This chapter describes the AMI UEFI BIOS setup utility for the BH12SSi-M25 and provides the instructions on navigating the setup screens. The BIOS is stored in a Flash EEPROM and can be updated.

Note: Due to periodic changes to the BIOS, some settings may have been added or deleted since this manual was published.

Starting BIOS Setup Utility

To enter the BIOS setup utility screens, press the key while the system is booting up. (There are a few cases when other keys are used, such as , , etc.)

The BIOS screens have three main frames. The large left frame displays options can be configured by the user. These are blue. When an option is selected, it is highlighted in white. Settings printed in Bold are the default values.

BIOS POST Codes

A.1 BIOS POST Messages

During the Power-On Self-Test (POST), the BIOS will check for problems. If a problem is found, the BIOS will activate an alarm or display a message. The following is a list of such BIOS messages.

BIOS POST Messages
BIOS Message Description
Failure Fixed Disk	Fixed disk is not working or not configured properly. Check to see if fixed disk is attached properly. Run Setup. Find out if the fixed-disk type is correctly identified.
Stuck key Stuck key on keyboard.
Keyboard error Keyboard not working.
Keyboard Controller Failed Keyboard controller failed test. May require replacing keyboard controller.
Keyboard locked - Unlock key switch	Unlock the system to proceed.
Monitor type does not match CMOS - Run SETUP	Monitor type not correctly identified in Setup
Shadow Ram Failed at offset: nnnn	Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
System RAM Failed at offset: nnnn	System RAM failed at offset nnnn of in the 64k block at which the error was detected.
Extended RAM Failed at offset: nnnn	Extended memory not working or not configured properly at offset nnnn.
System battery is dead - Replace and run SETUP	The CMOS clock battery indicator shows the battery is dead. Replace the battery and run Setup to reconfigure the system.
System CMOS checksum bad - Default configuration used	System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOS. The BIOS installed Default Setup Values. If you do not want these values, enter Setup and enter your own values. If the error persists, check the system battery or contact your dealer.
System timer error The timer test	failed. Requires repair of system board.
Real time clock error Real-Time	Clock fails BIOS hardware test. May require board repair.
Check date and time settings	BIOS found date or time out of range and reset the Real-Time Clock. May require setting legal date (1991-2099).
Previous boot incomplete - Default configuration used	Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail. On systems with control of wait states, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that the waitstate configuration is correct. This error is cleared the next time the system is booted.
Memory Size found by POST differed from CMOS	Memory size found by POST differed from CMOS.
Diskette drive A error
Diskette drive B error	Drive A: or B: is present but fails the BIOS POST diskette tests. Check to see that the drive is defined with the proper diskette type in Setup and that the diskette drive is attached correctly.
Incorrect Drive A type - run SETUP	Type of floppy drive A: not correctly identified in Setup.
Incorrect Drive B type - run SETUP	Type of floppy drive B: not correctly identified in Setup.
System cache error - Cache disabled	RAM cache failed and BIOS disabled the cache. On older boards, check the cache jumpers. You may have to replace the cache. See your dealer. A disabled cache slows system performance considerably.
CPU ID: CPU socket number for	Multi-Processor error.
EISA CMOS not writeable Server	BIOS2 test error: Cannot write to EISA CMOS.
DMA Test Failed	ServerBIOS2 test error: Cannot write to extended DMA (Direct Memory Access) registers.
Software NMI Failed	ServerBIOS2 test error: Cannot generate software NMI (Non-Maskable Interrupt).
Fail-Safe Timer NMI Failed Server	BIOS2 test error: Fail-Safe Timer takes too long.
device Address Conflict Address	conflict for specified device.
Allocation Error for: device	Run ISA or EISA Configuration Utility to resolve resource conflict for the specified device.
CD ROM Drive CD ROM Drive identified.
Entering SETUP... Starting Setup program
Failing Bits: nnnn	The hex number nnnn is a map of the bits at the RAM address which failed the memory test. Each 1 (one) in the map indicates a failed bit. See errors 230, 231, or 232 above for offset address of the failure in System, Extended, or Shadow memory.
Fixed Disk n Fixed disk n (0-3) identified.
Invalid System Configuration Data	Problem with NVRAM (CMOS) data.
I/O device IRQ conflict I/O device	IRQ conflict error.
PS/2 Mouse Boot Summary Screen:	PS/2 Mouse installed.
nnnn kB Extended RAM Passed	Where nnnn is the amount of RAM in kilobytes successfully tested.

One or more I2O Block Storage Devices were excluded from the Setup Boot Menu	There was not enough room in the IPL table to display all installed I2O block-storage devices.
Operating system not found	Operating system cannot be located on either drive A: or drive C:. Enter Setup and see if fixed disk and drive A: are properly identified.
Parity Check 1 nnnn	Parity error found in the system bus. BIOS attempts to locate the address and display it on the screen. If it cannot locate the address, it displays ???? . Parity is a method for checking errors in binary data. A parity error indicates that some data has been corrupted.
Parity Check 2 nnnn	Parity error found in the I/O bus. BIOS attempts to locate the address and display it on the screen. If it cannot locate the address, it displays ???? .
Pressto resume,to Setup,for previous	Displayed after any recoverable error message. Pressto start the boot process orter Setup and change the settings. Pressto display the previous screen (usually an initialization error of an Option ROM, i.e., an add-on card). Write down and follow the information shown on the screen.
Pressto enter Setup Optional message displayed during POST. Can be turned off in Setup.
PS/2 Mouse: PS/2 mouse identified.
Run the I2O Configuration Utility	One or more unclaimed block storage devices have the Configuration Request bit set in the LCT. Run an I2O Configuration Utility (e.g. the SAC utility).
System BIOS shadowed System	BIOS copied to shadow RAM.
UMB upper limit segment address: nnnn	Displays the address nnnn of the upper limit of Upper Memory Blocks, indicating released segments of the BIOS which can be reclaimed by a virtual memory manager.
Video BIOS shadowed Video BIOS	S successfully copied to shadow RAM.

A.2 BIOS POST Codes

This section lists the POST (Power-On Self-Test) codes for the AMI BIOS. POST codes are divided into two categories: recoverable and terminal.

Recoverable POST Errors

When a recoverable type of error occurs during POST, the BIOS will display an POST code that describes the problem. BIOS may also issue one of the following beep codes:

One long and two short beeps – video configuration error

One repetitive long beep – no memory detected

Terminal POST Errors

If a terminal type of error occurs, BIOS will shut down the system. Before doing so, BIOS will write the error to port 80h, attempt to initialize video and write the error in the top left corner of the screen.

The following is a list of codes that may be written to port 80h.

If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), it displays an additional word-bitmap (xxxx) indicating the address line or bits that failed. For example, "2C 0002" means address line 1 (bit one set) has failed. "2E 1020" means data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also sends the bitmap to the port-80 LED display. It first displays the checkpoint code, followed by a delay, the high-order byte, another delay, and then the low order byte of the error. It repeats this sequence continuously.
