System Safety

2-1 Overview

This chapter provides a quick setup to get your chassis up and running. Following

the steps in the order given should enable you to have your chassis set up and

operational within a minimal amount of time. This quick setup assumes that you are

an experienced technician, familiar with common concepts and terminology.

2-2 Warnings and Precautions

You should inspect the box the chassis was shipped in and note if it was damaged

in any way. If the chassis itself shows damage, le a damage claim with carrier

who delivered your system.

Decide on a suitable location for the rack unit that will hold that chassis. It should

be situated in a clean, dust-free area that is well venilated. Avoid areas where heat,

electrical noise and eletromagnetic elds are generated.

The system must be placed near at two grounded power outlets. When congured,

the SC837J chassis includes one primary and one redundant power supply.

2-3 Preparing for Setup

The SC837J chassis includes a set of rail assemblies which includes mounting

brackets and mounting screws you will need to install the systems into the rack.

Please read this manual in its entirety before you begin the installation proce-

dure.

2-1

SC837J Chassis Manual

2-4 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm

and the SC837J from damage:

•Be aware of the locations of the power on/off switch on the chassis as well

as the room’s emergency power-off switch, disconnection switch or electrical

outlet. If an electrical accident occurs, you can then quickly remove power from

the system.

•Do not work alone when working with high-voltage components.

•Power should always be disconnected from the system when removing or install-

ing main system components, such as the serverboard and memory modules

(not necessary for hot swappable drives). When disconnecting power, you

should rst power-down the system with the operating system and then unplug

the power cords from all the power supply modules in the system.

•When working around exposed electrical circuits, another person who is familiar

with the power-off controls should be nearby to switch off the power if neces-

sary.

•Use only one hand when working with powered-on electrical equipment. This

is to avoid making a complete circuit, which will cause electrical shock. Use

extreme caution when using metal tools, which can easily damage any electrical

components or circuit boards they come into contact with.

•Do not use mats designed to decrease electrostatic discharge as protection from

electrical shock. Instead, use rubber mats that have been specically designed

as electrical insulators.

•The power supply power cord must include a grounding plug and must be

plugged into a grounded electrical outlet.

•Serverboard battery: CAUTION - There is a danger of explosion if the onboard

battery is installed upside down, which will reverse its polarities This battery

must be replaced only with the same or an equivalent type recommended by

the manufacturer. Dispose of used batteries according to the manufacturer’s

instructions.

2-2

SC837J Chassis Manual

•Handle used batteries carefully. Do not damage the battery in any way; a dam-

aged battery may release hazardous materials into the environment. Do not

discard a used battery in the garbage or a public landll. Please comply with

the regulations set up by your local hazardous waste management agency to

dispose of your used battery properly.

2-5 General Safety Precautions

•Keep the area around the chassis clean and free of clutter.

•Place the chassis top cover and any system components that have been re-

moved away from the system or on a table so that they won’t accidentally be

stepped on.

•While working on the system, do not wear loose clothing such as neckties and

unbuttoned shirt sleeves, which can come into contact with electrical circuits or

be pulled into a cooling fan.

•Remove any jewelry or metal objects from your body, which are excellent metal

conductors that can create short circuits and harm you if they come into contact

with printed circuit boards or areas where power is present.

•After accessing the inside of the system, close the system back up and secure

it to the rack unit with the retention screws after ensuring that all connections

have been made.

2-6 System Safety

Electrostatic discharge (ESD) is generated by two objects with different electrical

charges coming into contact with each other. An electrical discharge is created to

neutralize this difference, which can damage electronic components and printed

circuit boards. The following measures are generally sufcient to neutralize this

difference before contact is made to protect your equipment from ESD:

•Do not use mats designed to decrease electrostatic discharge as protection from

electrical shock. Instead, use rubber mats that have been specically designed

as electrical insulators.

•Use a grounded wrist strap designed to prevent static discharge.

•Keep all components and printed circuit boards (PCBs) in their antistatic bags

until ready for use.

2-3

SC837J Chassis Manual

•Touch a grounded metal object before removing any board from its antistatic

bag.

•Do not let components or PCBs come into contact with your clothing, which may

retain a charge even if you are wearing a wrist strap.

•Handle a board by its edges only; do not touch its components, peripheral chips,

memory modules or contacts.

•When handling chips or modules, avoid touching their pins.

•Put the serverboard and peripherals back into their antistatic bags when not

in use.

•For grounding purposes, make sure your computer chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the serverboard.

3-1

SC837J Chassis Manual

3-2 Control Panel Buttons

There are two push-buttons located on the left handle of the chassis. These are

(in order from top to bottom) a power on/off button and a reset button.

Power: The main power button 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 ser vicing.

Reset: The reset button is used to reboot the system.

3-3 Control Panel LEDs

The control panel located on the left handle of the SC837J chassis has ve 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.

Rack Installation

5-1 Overview

This chapter provides a quick setup for installing the chassis into a rack. Following

these steps in the order given should enable you to have the system installed within

a minimum amount of time.

5-2 Unpacking the System

You should inspect the box the chassis was shipped in and note if it was damaged

in any way. If the chassis itself shows damage you should le 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 elds are generated. You will also need to posi-

tion the rack near a grounded power outlet. Be sure to read the Rack Precautions

and General Server Precautions in the next section.

5-3 Preparing for Setup

The box your chassis was shipped in includes a set of rail assemblies (two inner

rails and two outer rails). and the mounting screws you will need to install the system

into the rack. 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

sufcient airow and ease in servicing.

5-1

SC837J Chassis Manual

!

Warnings and Precautions!

!

•This product is for installation only in a Restricted Access Location (dedicated

equipment rooms, service closets and the like).

Rack Precautions

•Ensure that the leveling jacks on the bottom of the rack are fully extended to

the oor with the full weight of the rack resting on them.

•In single rack installation, 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 component from the

rack.

•You should extend only one component at a time - extending two or more si-

multaneously may cause the rack to become unstable.

General Server Precautions

•Review the electrical and general safety precautions that came with the com-

ponents 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 rst, and then

work up.

•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 touch-

ing them.

SC837J Chassis Manual

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating tem-

perature 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.

ReducedAirow

Equipment should be mounted into a rack so that the amount of airow 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 connec-

tions other than the direct connections to the branch circuit (for example, the use

of power strips, etc.).

5-3

SC837J Chassis Manual

5-4 Rack Mounting Instructions

Outer rails attach to the server rack and hold the chassis in place. The outer rails

for the SC837J chassis extend between thirty inches and thirty-three inches.

Installing the Outer Rails

1. Begin by measuring the distance from the front to the back of the rack.

2. Slide the shorter outer rail (A) into the longer outer rail (B).

3. Attach the front of the shorter outer rail (A) to the front of the rack and the

back of the longer outer rail (B) to the rear of the rack.

4. Adjust both the shorter and longer outer rails to the proper distance so that

they t snugly into the rack and secure with the screws provided.

5. Press the release tab (C) on the inside of the outer rail to release the outer

rail extension (D)

6. Repeat steps 1 through 5 for the remaining outer rail.

To avoid personal injury and property damage, carefully follow all the safety steps

listed below when accessing your system or handling the components.

C-1 ESD Safety Guidelines

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-

age to your system, it is important to handle it very carefully. The following measures

are generally sufcient to protect your equipment from ESD.

•Use a grounded wrist strap designed to prevent static discharge.

•Touch a grounded metal object before removing a component from the antistatic

bag.

•Handle the backplane by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

•When handling chips or modules, avoid touching their pins.

•Put the backplane and peripherals back into their antistatic bags when not in

use.

C-2 General Safety Guidelines

•Always disconnect power cables before installing or removing any components

from the computer, including the backplane.

•Disconnect the power cable before installing or removing any cables from the

backplane.

•Make sure that the backplane is securely and properly installed on the mother-

board to prevent damage to the system due to power shortage.

Explanation of Jumpers

To modify the operation of the backplane,

jumpers can be used to choose between

optional settings. Jumpers create shorts

between two pins to change the function

of the connector. Pin 1 is identied with

a square solder pad on the printed circuit

board. Note: On two pin jumpers, "Closed"

means the jumper is on and "Open" means

the jumper is off the pins.

C-12 Failover with RAID Cards and Multiple HBAs

The SAS-837EL2 backplane may be congured for failover with multiple HBAs using

either RAID controllers or HBAs to acheive 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 congured to perform

the load balancing and failover tasks.

Dual Host Bus
Adapter

In a dual host bus congura-

to two Host Bus Adapters.

Dual Host Bus
Adapter Failover

If the expander or data path

in the primary ports fails, the

system automatically switches

to the secondary ports. This

maintains a full connection to

all drives. Note that this con-

figuration requires additional

MPIO software. Contact your

Supermicro authorized repre-

sentative for details.

SC837J Chassis Manual

C-14 SupportedCascadingCongurations

Cascading allows the system to access data at a faster rate by allowing several

backplanes to share resources to reduce latency time.

The rst backplane in a cascaded system requires a motherboard and an HBA.

Other servers require a power control card but no motherboard and no HBA.

SAS-837ABackplaneSpecications

To avoid personal injury and property damage, carefully follow all the safety steps

listed below when accessing your system or handling the components.

D-1 ESD Safety Guidelines

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-

age to your system, it is important to handle it very carefully. The following measures

are generally sufcient to protect your equipment from ESD.

•Use a grounded wrist strap designed to prevent static discharge.

•Touch a grounded metal object before removing a component from the antistatic

bag.

•Handle the backplane by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

•When handling chips or modules, avoid touching their pins.

•Put the backplane and peripherals back into their antistatic bags when not in

use.

D-2 General Safety Guidelines

•Always disconnect power cables before installing or removing any components

from the computer, including the backplane.

•Disconnect the power cable before installing or removing any cables from the

backplane.

•Make sure that the backplane is securely and properly installed on the mother-

board to prevent damage to the system due to power shortage.
