1
1 Accessing the System
This chapter lists hand tools and describes servicing restrictions, opening the base unit, avoiding
electrostatic discharge, removing and attaching the face plate, and closing the base unit.
This system features a telescoping chassis that provides increased serviceability and access to internal
components. The telescoping section, to which the system board is mounted, is secured by five screws
and slides out from the rear.
NOTE “Right side” and “left side” are as seen from the front of the base unit.
CAUTION Follow all warnings and cautions in servicing instructions. Personal injury and damage to equipment
can occur if documented procedures are not followed.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
Tools
You will need the following tools to service the system:
u Antistatic wrist strap
u Quarter-inch nutdriver
u No. 1 and No. 2 Phillips screwdrivers
u Three-sixteenth-inch nutdriver
u Five-sixteenth-inch or 8 mm nutdriver
u Small single-slot screwdriver
Opening the Base Unit
CAUTION Shut the system down and turn the system power off. Use caution to avoid injury when removing
covers and other hardware.
CAUTION If the system is installed in a free-standing rack, ensure front and side stabilizers are fully extended.
To open the base unit:
1. Remove the screws that secure the face plate to the rack.
2. Slide the system out of the rack until it locks in the extended position.
3. Remove the following eight screws that secure the cover to the chassis: One at right and left top
corners of face plate; two at top, back of cover; and two at right and left sides, back of cover.
4. Slide the cover back about an inch, then lift the cover off.
5. Attach grounding clip from antistatic wrist strap to bare metal.

2
Protecting Against Electrostatic Discharge
Sensitive components inside the base unit can be damaged by static electricity. To protect against this
possibility, take the following precautions when working with the system’s internal components.
u Touch the bare metal of the base unit to ensure it and your body are at the same electric potential.
u Handle all printed circuit boards as little as possible and by the edges only. Leave new parts in
their protective packaging until you install them.
u Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system. Once
a disposable wrist strap is used, it cannot be used again. A reusable antistatic wrist strap can be
attached to any bare metal part of the base unit. The metal conductor bead in the elastic sleeve of
reusable antistatic straps must contact bare skin.
Removing the Face Plate
To remove the face plate:
1. Remove the cover.
2. Remove one lower screw on each side of system front that secures handle to the base unit.
3. Remove the six screws that secure face plate to the base unit.
4. Pull the face plate toward you to remove it. Note how the bottom lip of the face plate attaches to
the cutout in front of the power supply.
Attaching the Face Plate
To attach the face plate:
1. Push the face plate onto the base unit. Ensure that the top part of the lip at bottom slides over the
cutout in front of the power supply.
2. Adjust the face plate as needed to ensure all components are flush.
3. Secure the face plate to the base unit.
4. Close the cover.
Closing the Base Unit
CAUTION After servicing the system, always replace the covers that were removed. The covers ensure the
system maintains proper air flow, so internal components do not overheat and fail. The covers also
ensure that electromagnetic interference (EMI) emissions remain below the standard requirements.
To close the base unit:
1. Remove the antistatic wrist strap from the base unit.
2. Replace the cover.
3. Slide the base unit into the rack.
4. Secure the base unit with screws at each corner of the face plate.

2 Servicing the System
This chapter describes how to replace the standard parts within the system.
NOTE Refer to Chapter 1 for details on opening the system and protecting against electrostatic discharge.
CAUTION Follow all warnings and cautions in servicing instructions. Personal injury and damage to equipment
can occur if documented procedures are not followed.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
