1 Accessing the System
This chapter lists tools and describes protecting against electrostatic discharge. It also describes
opening and closing the case, and accessing components behind the power supply.
This system features a new, extensible chassis architecture designed for ease of upgrades and
expansion. The design provides easy access to PCI and ISA card slots, memory, processors, and the
power supply. You do not need any tools to open the InterServe 80 case.
NOTE “Right side” and “left side” are as seen from the front of the unit.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
WARNING Follow all warnings and cautions in the servicing instructions. If you fail to follow
documented, approved procedures, personal injury and damage to equipment can result.
Tools
You will need the following tools to service the system:
u Antistatic wrist strap
u Antistatic mat connected to an earth ground
u Quarter-inch nutdriver
u No. 1 and No. 2 Phillips screwdrivers
u Small or medium flat-blade standard screwdriver
Protecting Against Electrostatic Discharge
Electrostatic discharge (ESD) can damage sensitive components inside the unit. Take the following
precautions when working with internal components:
u Unplug the unit from AC power before servicing any electronic component inside the chassis.
Remember that the InterServe 80 is always on when connected to AC power.
u Touch the bare metal of the chassis to ensure the chassis and your body are at the same electric
potential.
u Attach the antistatic wrist strap to its connector on the antistatic mat. Ensure that the metal
conductor bead in the elastic sleeve of the antistatic strap contacts bare skin.
u Handle all printed circuit boards as little as possible and by the edges only.
u Leave new parts in their protective packaging until you install them.

2
Opening and Closing the Case
Opening the system for service or upgrades consists of two simple steps. Remove the top cover first,
then remove the left side panel. No tools are needed. You need only remove the top cover and left
side panel for most routine service procedures. See Chapter 2, “Servicing the System,” for additional
details on removing and replacing case components.
CAUTION Do not use the bottom portion of the face panel or the lip at the top rear of the unit as a hand hold
when moving the system. Equipment damage and personal injury can result.
The left side panel has a tab that closes an interlock switch inside the power supply. When you take
off the left side panel, the safety interlock removes AC power to the system.
WARNING Do not attempt to defeat the safety interlock and run the system with the left side panel
removed. Personal injury and equipment damage can result.
CAUTION Before you open the case, shut down the system and turn off power to the system and external
devices (including peripheral drives and display). Use caution to avoid injury when lifting the
computer or removing covers and other hardware.
To open the case:
1. Ensure the system is shut down and that you have disconnected the system and any attached
external devices from AC power.
2. Grasp the lip on the top cover at the rear of the system and press up on the release.
Press up on release located under lip
3. Keep pressing the release, slide the top cover back until it stops, remove it from the chassis, and
set it aside.

3
4. Do the following to remove a side panel.
− Grasp the cowling at the bottom of the side panel and lift.
− Slide the side panel back until it stops, and then remove it from the chassis.
NOTE Removing the right side panel is necessary only for servicing internal bay disk drives, the plastic
cowling on the right panel, or the face panel.
To close the case:
1. Place the side panel on the chassis so that all tabs on the rear of the chassis insert into their slots.
NOTE When installing the left side panel, ensure that the security tab aligns with its corresponding slot on
the panel.
2. Push the side panel toward the front of the chassis, then push down to seat the panel.
3. Repeat steps 1 and 2 above to install the remaining side panel, if necessary.
4. Place the top cover on the chassis so that all tabs are inserted into their slots.
5. Slide the top cover forward until it locks into place.
CAUTION After servicing or upgrading the system, always replace the covers that were removed. Do not defeat
the AC interlock. 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.
Accessing Components Behind the Power Supply
The power supply swings away from the system board, giving you easy access to the processors,
DIMMs, and other components. You can remove the power supply entirely, but this is not necessary
for most routine service or upgrade tasks. As needed, you may want to disconnect power supply
cables to peripheral devices to swing the power supply out fully.
See Chapter 2, “Servicing the System,” for complete details on removing the power supply.
To access components behind the power supply:
1. Unplug the AC power cord from the rear of the unit.
2. Remove the top cover and left side panel. See the previous section for details.
3. Remove the knurled retaining/grounding screw just below the top system fan on the rear of the
chassis.

4
4. Grasp both knurled plungers on the power supply, pull them toward each other, and then swing
the power supply toward you.
Bottom plunger
Top plunger
NOTE Disconnect power cables to internal devices as needed to allow the power supply to swing out fully.
5. Access the exposed components as needed.
To stow the power supply:
1. Reconnect any power cables that you disconnected.
2. Grasp both knurled plungers, pull them toward each other, and then swing the power supply
away from you, back into the chassis.
CAUTION Carefully swing the power supply back into the chassis. Avoid pinching cables. Hold the external
SCSI cable against the chassis brace or rearrange cables slightly while swinging the power supply into
the chassis.
3. Align the plunger holes and release both plungers.
4. Install the retaining/grounding screw on the rear panel.
5. Install the left side panel and top cover.
6. Plug the AC power cord into its connector on the rear of the chassis.

2 Servicing the System
This chapter describes how to replace the standard parts within the system. Heed all warning and
caution labels while replacing parts. These servicing procedures assume you have removed the left
side panel from the system, and have taken antistatic precautions, as described in Chapter 1. After
you have finished servicing the system, replace panels as described in Chapter 1.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
CAUTION Do not overtighten screws and other fasteners to avoid damaging threads.
WARNING Disconnect the system from AC power before servicing internal components! Failure to
remove AC power may result in equipment damage or personal injury.
WARNING Follow all warnings and cautions in servicing instructions. If you fail to follow documented,
approved procedures, personal injury or damage to equipment can result.

8. Perform steps 2 and 3 in the “To replace the hinge rails” procedure below.
9. Orient the new hinge so that the locking tabs face down and insert the new hinge into the track
and push it forward until it stops.
10. Hold the hinge, align the beveled edges of the hinge with the guide slots on the door, and push
the door firmly onto the hinge until it snaps into place.
11. Press the two emblems onto the door until they snap into place.
12. Operate the door to test its movement.
13. Install the top cover.

4. Remove the hinge from the rail.
5. Press a hinge rail toward the middle of the chassis until all four tabs release.
6. Lift the hinge rail off the chassis.
7. Orient the new hinge rail the same way as the one you removed, place the tabs in the slots, and
press outward until the rail snaps into place.
8. From the front of the chassis, slide the hinge into the rails.
To replace the face panel:
1. Remove the top cover and both side panels as described in Chapter 1.
2. Remove the door. See the “To replace the door assembly” procedure above for details.
3. Push the hinge back, away from the front of the chassis.
4. Use a flat-blade screwdriver to gently pry and release each of the plastic tabs on both sides of the
chassis. The tabs on the right side of the chassis are recessed. First release the bottom tabs,
