4-1 Overview

Several buttons and LEDs indicate the status of the system. The control panel on the front edge of the chassis includes power buttons and status LEDs. There are also LEDs on the drive carriers the indicate the status of the drive.

This chapter explains the LED indicators and responses.

4-2 Control Panel Buttons

There are two push-buttons located on the front of the chassis. These are a power on/off button and a reset button.

Power: The main power switch is used to apply or remove power from the power supply to the server system. Turning off system power with this button removes the main power but keeps standby power supplied to the system. Therefore, you must unplug system before servicing.

Reset: The reset button is used to reboot the system. A needle, pen, or other small device is required to activate this button and reset the system

4-3 Control Panel LEDs

The control panel located on the front of the SC216 chassis has five LEDs. These LEDs provide you with critical information related to different parts of the system. This section explains what each LED indicates when illuminated and any corrective action you may need to take.

Power: Indicates power is being supplied to the system's power supply units. This LED should normally be illuminated when the system is operating.

HDD: Indicates IDE channel activity. SAS/SATA drive and/or DVD-ROM drive activity when flashing.

NIC2: Indicates network activity on GLAN2 when flashing.

NIC1: Indicates network activity on GLAN1 when flashing.

Power Failure: When this LED flashes, it indicates a power failure in the power supply.

Information LED: Alerts operator of several states, as noted in the table below.

Informational LED
Status Description
Continuously on and red	An overheat condition has occurred. (This may be caused by cable congestion.)
Blinking red (1Hz) Fan failure	check for an inoperative fan.
Blinking red (0.25Hz) Power	failure, check for a non-operational power supply.
Solid blue	Local UID has been activated. Use this function to locate the server in a rack mount environment.
Blinking blue	Remote UID is on. Use this function to identify the server from a remote location.

4-4 Drive Carrier LEDs

The SC216 chassis supports SAS/SATA drives.

SAS/SATA Drives

Each SAS/SATA drive carrier has two LEDs.

• Green or Blue: Each hard disk drive carrier has either a green or a blue LED, depending upon the hard disk drives and backplane used. When illuminated, this LED indicates drive activity. A connection to the SATA backplane enables this LED to blink on and off when that particular drive is being accessed.
• Red: The red LED indicates a SAS/SATA drive failure. If one of the SAS/SATA drives fail, you should be notified by your system management software.

Notes

Chapter 6

Rack Installation

6-1 Overview

This chapter provides a quick setup to get your chassis up and running. Following these steps in the order given should enable you to have the system operational within a minimal amount of time.

6-2 Unpacking the System

You should inspect the box which the chassis was shipped in and note if it was damaged in any way. If the chassis itself shows damage, you should file a damage claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold your chassis. 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. The system needs to be placed near a grounded power outlet. Be sure to read the Rack and Server Precautions in the next section.

6-3 Preparing for Setup

The box your chassis was shipped in should include two sets of rail assemblies and the mounting screws needed for installing the system into the rack. Also included is an optional square hole to round hole converter bracket, for use in racks with round mounting holes. Please read this section in its entirety before you begin the installation procedure outlined in the sections that follow.

Choosing a Setup Location

• Leave enough clearance in front of the rack to enable you to open the front door completely (\~25 inches).
• Leave approximately 30 inches of clearance in the back of the rack to allow for sufficient airflow and ease in servicing.
• This product is for installation only in a Restricted Access Location (dedicated equipment rooms, service closets and the like).

6-4 Warnings and Precautions

Rack Precautions

• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting 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 that the rack is stable before extending a component from the rack.
• You should extend only one component at a time - extending two or more simultaneously may cause the rack to become unstable.

General Server Precautions

• Review the electrical and general safety precautions that came with the components you are adding to your chassis.
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components on the bottom of the rack first, and then work upwards.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges, voltage spikes and to keep your system operating in case of a power failure.
• Allow the hot plug hard drives and power supply modules to cool before touching them.
• Always keep the rack's front door and all panels and components on the servers closed when not servicing 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 ambient temperature of the room. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature (TMRA).

Reduced 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.).

Warning: 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.

6-5 Rack Mounting Instructions

This section provides information on installing the chassis into a rack unit with the rails provided. There are a variety of rack units on the market, which may mean that the assembly procedure will differ slightly from the instructions provided. You should also refer to the installation instructions that came with the rack unit you are using. Note: This rail will fit a rack between 26.5" and 36.4" deep.

Identifying the Sections of the Rack Rails

The chassis package includes two rail assemblies in the rack mounting kit. Each assembly consists of three sections: An inner chassis rail which secures directly to the chassis, an outer rail that secures to the rack, and a middle rail which extends from the outer rail. These assemblies are specifically designed for the left and right side of the chassis.

Figure 6-1. Identifying the Outer Rail, Middle Rail and Inner Rails (Left Rail Assembly Shown)

Locking Tabs

Each inner rail has a locking tab. This tab locks the chassis into place when installed and pushed fully into the rack. These tabs also lock the chassis in place when fully extended from the rack. This prevents the server from coming completely out of the rack when when the chassis is pulled out for servicing.

Releasing the Inner Rail

Releasing Inner Rail from the Outer Rails

1. Identify the left and right outer rail assemblies as described on page 6-4.
2. Pull the inner rail out of the outer rail until it is fully extended as illustrated below.
3. Press the locking tab down to release the inner rail.
4. Repeat steps 1-3 for the second outer rail.

Dual Port and Cascading Configurations

E-9 Single and Dual Port Expanders

Single Ports

SAS2-216EL1 model backplanes have a single-port expander on the daughter card that accesses all of the drives and supports cascading.

Figure E-5: SAS2-216EL1 Single Port Configuration

Dual Ports

SAS2-216EL2 model backplanes have dual-port expanders on the daughter cards that access all of the hard drives. These dual-port expanders support cascading, failover, and recovery.

Figure E-6. SAS2-216EL2 Dual Port Configuration

E-10 Failover

Single Host Bus Adapter Failover

If the expander or data path in Port A fails, the system automatically switches to Port B.

Figure E-8. Single HBA Failover

E-11 Failover with RAID Cards and Multiple HBAs

The SAS-216EL backplane may be configured for failover with multiple HBAs using either RAID controllers or HBAs to achieve failover protection.

RAID Controllers: If RAID controllers are used, then the failover is accomplished through port failover on the same RAID card.

HBAs: If multiple HBAs are used to achieve failover protection and load balancing, Linux MPIO software must be installed and correctly configured to perform the load balancing and failover tasks.

Dual Host Bus Adapter

In a dual host bus configuration, the backplane connects to two HBA's.

IMPORTANT: See Section 3-3 of this manual, Failover with RAID Cards and Multiple HBAs for important information on supported configurations.

G-13 Supported Cascading Configurations

Cascading allows the system to access data at a faster rate by allowing several backplanes to share resources to reduce latency time.

The first backplane in a cascaded system requires a motherboard and an HBA. Other servers require a chassis control card with no motherboard and no HBA. For more information, specific chassis manuals are available at www.supermicro.com.
