2-1

Chapter 2: System Safety

Chapter 2

System Safety

2-1 Overview

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

Following the steps in 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 ventilated. Avoid areas where heat,

electrical noise and electromagnetic elds are generated.

You will also need to place the chassis near at least one grounded power outlet.

When congured, the SC118G chassis includes one primary and in R-model chas-

sis, one primary and one redundant power supply.

2-3 Preparing for Setup

The SC118G chassis includes a set of rail assemblies, including mounting brackets

and mounting screws you will need to install the system into the rack. Please read

this manual in its entirety before beginning the installation procedure.

2-4 Electrical Safety Precautions

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

and the SC118G 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.

SC118G Chassis Manual

2-2

•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 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 one grounded electrical outlet on standard chassis, two grounded

outlets with rudundant power supply R-model chassis.

•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. (CR2032) Dispose of used batteries according to the manu-

facturer’s instructions.

•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.

2-3

Chapter 2: System Safety

•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.

•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 the backplane 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.

SC118G Chassis Manual

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

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

the serverboard.

•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.

4-3 Control Panel LEDs

The control panel located on the front of the SC118G chassis has ve LEDs. These

LEDs provide critical information related to different parts of the system. This sec-

tion explains what each LED indicates when illuminated and any action that may

be required.

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

4-2 Control Panel Buttons

The SC118G chassis includes two push-buttons located on the front panel: a reset

button and a power on/off button.

•Overheat/Fan Fail: When this LED ashes it indicates a fan failure. When

continuously on (not ashing), it indicates an overheat condition, which may

be caused by cables obstructing the airow in the system or the ambient room

temperature being too warm. Check the routing of the cables and make sure

all fans are present and operating normally. You should also check to make

sure that the chassis covers are installed. Finally, verify that the heatsinks are

installed properly. This LED will remain ashing or on as long as the overheat

condition exists.
