Chapter 2: System Safety

Chapter 2

System Safety

2-1 Overview

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

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

tional within a minimal amount of time. These instructions assume 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 the carrier

who delivered your system.

Decide on a suitable location for the rack unit that will hold the 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 it placed near at least two grounded power outlets. The SC836

chassis includes two redundant power supplies which require two grounded out-

lets.

2-3 Preparing for Setup

The SC836 chassis includes a set of rail assemblies, including 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 procedure.

SC836 Chassis Manual

2-2

2-4 Electrical Safety Precautions

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

and the SC836 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 in-

stalling main system components, such as the serverboard, memory modules

and the DVD-ROM (not necessary for hot-swappable drives). When discon-

necting 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 fa-

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

necessary.

•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 grounded electrical outlets.

•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.

2-3

Chapter 2: System Safety

•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.

•DVD-ROM laser: CAUTION - this server may have come equipped with a

DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous

radiation exposure, do not open the enclosure or use the unit in any uncon-

ventional way.

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.

SC836 Chassis Manual

2-4

•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.

•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.

Chapter 5: Chassis Setup and Maintenance

5-5 Installing the Motherboard

Permanent and Optional Standoffs

Standoffs prevent short circuits by creating space between the motherboard and

the chassis surface. The SC836 chassis includes permanent standoffs in locations

used by most motherboards. These standoffs accept the rounded Phillips head

screws included in the SC836 accessories packaging.

Some motherboard require additional screws for heatsinks, general components

and/or non-standard securing within the chassis. Optional standoffs are included to

these motherboards. To use an optional standoff, you must place it into the desired

position in the chassis and secure it with a screw.

Standoffs Labeling

Standoff locations are labeled on the bottom of the SC836 chassis with the letters:

P, D, and A.

P = Most compatible motherboards have a processor or CPU located here. If neces-

sary, place standoffs here for the CPU's heatsink.

D = Place optional standoffs here if your motherboard requires additional posts to

hold the unit in place.

A = A number of older motherboards have processors or CPUs located in areas

designated "A". Place standoffs here for the CPU's heatsink.

Motherboard Installation

Installing the Motherboard

1. Review the documentation that came with your motherboard. Become familiar

with component placement, requirements, and precautions.

2. Conrm that the power supply is disconnected and lay the chassis on a at

surface.

3. Open the chassis cover.

SC836 Chassis Manual

5-6

4. Remove any packaging from the chassis. If the rear fans (set of two fans

nearest the I/O slots) or the air shroud are in place, remove them.

5. If required by your motherboard, install standoffs in any areas that do not

have a permanent standoff. To do this, place an optional hexagonal standoff

into the chassis and secure it with a screw. Compare the holes in the mother-

board to those in the chassis and add or remove standoffs as needed.

6. Lay the motherboard in the chassis, aligning the permanent and optional

standoffs.

7. Secure the motherboard to the chassis using the rounded, Phillips head

screws. Do not exceed eight pounds of torque per square inch when tighten-

ing down the motherboard.

8. Secure the CPU(s) and heatsinks to the motherboard.

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-13 Failover with RAID Cards and Multiple HBAs

The SAS-836EL 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.

status of each SAS drive. These activity LED

headers are used by the host controller for

the SATA drives that previously had no activ-

ity status output. If using a SAS drive, and

for most SATA drives, these activity headers

are not required.The Activity LED Header is

located on the front panel. For the Activity

LED Header to work properly, connect using a

10-pin LED cable.

SAS-836A 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.

E-1 ESD Safety Guidelines

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

to your system, it is important to handle the backplane 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 card and peripherals back into their antistatic bags when not in use.

E-2 General Safety Guidelines

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

from the computer, including this backplane.

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

backplane.

The activity LED headers, designated JP26

and JP47, are used to indicate the activity

status of each SAS drive. These activity LED

headers are used by the host controller for

the SATA drives that previously had no activ-

ity status output. If using a SAS drive, and

for most SATA drives, these activity headers

are not required.The Activity LED Header is

located on the front panel. For the Activity

LED Header to work properly, connect using a

10-pin LED cable.

E-7 Front Jumper Locations and Pin Denitions

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.

#3. Power Fault Connector (MCU Power On

Switch)

In normal operating mode, power is governed

by the MCU (Micro Controller Unit). As a ser-

curity measure, the switch must be depressed

for at least four seconds to power down the

system.

In the case of an unexpeceted loss of power,

the MCU will return the system to the power

state it was in at the time when power was

lost.

#4. LED and Switch Connector

The LED Header and Switch Connector,

designated JF1, is cabled directly to the front

panel. This allows the front panel to display

system status.

#1. Fan Connectors

The 3-pin connectors, designated Fan1 and

Fan2, provide power to the fans.

Since the system will use the power card

instead of a motherboard, two fans provide

sufcient cooling for the server.
