Notes:

• SAS drives are only supported when proper Intel RAID C600 Upgrade Key or Intel Integrated RAID Module is installed.

• Drives can consume up to 17 watts of power each. Drives must be specified to run at a maximum ambient temperature of 45ºC.

Slimline Optical Drives

The slimline optical drive carrier can be used with a single slimline optical drive. One slim line carrier is included with your server system. The optical drive must be purchased separately.

The drive in the optical drive carrier is NOT hot-swappable. The system power must be turned off to insert or remove the slimline optical drive carrier.

2. System Safety

This chapter describes basic safety precautions.

Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm and the SGI UV 20 system from damage, as follows:

• 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 installing main system

components, such as the serverboard, memory modules and disk drives. When disconnecting power, you should first power down the operating system first and then unplug the power cords. The unit has more than one power supply cord. Disconnect two power supply cords before servicing to avoid electrical shock .

• 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 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 static electrical discharge as protection from electrical

shock. Instead, use rubber mats that have been specifically designed as electrical insulators.

• The power supply power cords must include a grounding plug and must be plugged into

grounded electrical outlets.

007-5900-001 11

2: System Safety

• Serverboard Battery

Caution: There is a danger of explosion if the onboard battery is installed upside down,

!

which will reverse its polarites (see Figure 2-1). 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.

• Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive T emperature Coef ficient) fuses on the mainboard must be replaced by trained service technicians only. The new fuse must be the same or equivalent as the one replaced. Contact technical support for details and support.

General Safety Precautions

Follow these rules to ensure general safety:

• Keep the area around the SGI UV 20 system clean and free of clutter.

• The SGI UV 20 system might approach 75 lbs (38 kg) when fully loaded. When lifting the system, two people at either end should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.

• Place the chassis top cover and any system components that have been removed 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.

General Safety Precautions

007-5900-001 13

2: System Safety

ESD Precautions

!

Caution: 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 com ponents and printed circuit boards.

The following measures are generally sufficient to neutralize this difference before contact is made to protect your equipment from ESD:

• 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 the board from the 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. System Operation and Monitoring

Figure 3-1 shows the control panel at the top right of the front panel. There are several LEDs on

the control panel as well as others on the hard drive carriers and power supplies. The LEDs keep you constantly informed of the overall status of the system as well as the activity and health of specific components. There are also control buttons on the control panel. This chapter describes the buttons and LEDs.

3: System Operation and Monitoring

Notes:

• Blink rate is ~1 Hz at 50% duty cycle.

• It is also off when the system is powered off (S5) or in a sleep state (S1).

• The power LED sleep indication is maintained on standby by the chipset. If the system is powered down without going through the BIOS, the LED state in effect at the time of power off is restored when the system is powered on until the BIOS clear it.

• If the system is not powered down normally, it is possible the Power LED will blink at the same time the system status LED is off due to a failure or configuration change that prevents the BIOS from running.

4. Chassis Maintenance

For warranty and safety considerations, SGI designates the following chassis components as customer-replaceable units (CRUs):

• Power supplies

•Fans

• Disk drives

These components are all hot-swappable; that is, you can replace them without powering down the server. A trained service technician should install and replace all other components.

This chapter describes the following chassis maintenance activities:

• “Removing and Installing the Front Fan Bezel” on page 23

• “Removing the Rack Handles” on page 25

• “Installing the Rack Handles” on page 26

• “Removing the System Top Cover” on page 27

• “Replacing the System Cover” on page 29

Removing the System Top Cover

The server system must be operated with the system cover in place to ensure proper cooling. You will need to remove the top cover to add or replace components inside of the server. Before removing the top cover, power down the server and unplug all peripheral devices and the power cable(s).

Note: A non-skid surface or a stop behind the server system may be needed to prevent the server system from sliding on your work surface.

To remove the system cover, use the following steps:

1. Observe the safety and ESD precautions in Chapter 2, “System Safety.”.

2. Turn off all peripheral devices connected to the server.

3. Turn off the server.

4. Disconnect the power cord.
