1 Accessing the System
This chapter describes how to access the internal components of the system so you can service and
upgrade an InterServe 8000 server.
Before You Begin
WARNING Heed all warnings and cautions in the accessing, servicing and upgrading instructions.
Personal injury and damage to equipment can occur if documented procedures are not
followed.
CAUTION The system produces high-leakage current. Flip the circuit breaker (if included) to the OFF position
when servicing or upgrading the base unit.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge (ESD). ESD can damage components inside the system.
Opening the Base Unit
The system contains safety interlock switches that turn the system power off when you remove a side
panel (in systems with 550 Watt power supplies) or the power supply cover (in systems with 539 Watt
power supply). You do not have to manually power off the system before servicing, but you must log
off and shut down the operating system to preserve data on the disk drives.
The side panels are secured using twist locks on the back of the unit, so you need no tools to remove
them. The following table shows which panel to remove to access the internal components. The right
side and left side are as viewed from the front of the system.
Right Side Panel Left Side Panel Both Side Panels
I/O Connector Board Processor Board CD-ROM Drive
I/O Expansion Panel Memory Floppy Disk (or Combo) Drive
AC Section Processors Power Distribution Board Assembly
Main Cooling Fans 5.25-inch Option Devices
LCD Board
RAID Section
NOTE The power supplies and disk drives can be removed without taking off the side panels.
CAUTION Use caution to avoid injury when removing side panels and other hardware.
WARNING For units installed in a standalone rack, ensure the rack’s front and side stabilizers are
extended at all times. If the rack includes adjustable feet on the stabilizers, they must be in full
contact with the floor. If the rack includes locking casters, they should be locked.

2
To open the base unit:
1. Defeat the system’s intruder alert. See the System Setup document delivered with the system for
more information.
2. Log off and shut down the operating system.
3. Flip the circuit breaker switch to the OFF position.
4. If the base unit is in a rack and uses Intergraph sliding shelves, slide the unit out of the rack.
− Remove the screw (located under the sliding shelf handle) securing the sliding shelf to the
rack.
− Disengage the sliding shelf by lifting the release lever.
− Pull the shelf out until it locks in the extended position. The rear of the base unit should clear
the front of the rack by two inches. You may need to disconnect cables to fully extend the
unit.
− The base unit can remain on the shelf during the servicing or upgrade procedures.
WARNING For units installed in a standalone rack, ensure the rack’s front and side stabilizers are
extended at all times. If the rack includes adjustable feet on the stabilizers, they must be in full
contact with the floor. If the rack includes locking casters, they should be locked.
5. Locate the twist locks on the back of the base unit. Turn the locks counter-clockwise to disengage
the side panels.
6. Pull the side panels back an inch then lift them off the unit. The system power turns off
automatically when either side panel is removed. Figures on the following pages show internal
views of the system.
7. Before performing the service or upgrade procedure, review the section “Avoiding Electrostatic
Discharge.”

The following figure shows the system with the left side panel removed (processor board side).

4
The following figure shows the system with the right side panel removed (I/O expansion board side).

5
Avoiding 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 the base unit 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.
u A reusable antistatic wrist strap can be attached to any bare metal part of the base unit. The metal
conductor in the elastic sleeve of reusable antistatic straps must contact bare skin.
Closing the Base Unit
CAUTION After servicing or upgrading the system, always replace the panels that were removed. The panels
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. The system will not start unless the panels are properly replaced.
To close the base unit:
1. Disconnect the antistatic wrist strap from the base unit.
2. Replace the side panels and turn the twist locks clockwise to lock the panels into place.
3. If the unit is rack-mounted:
− Unlock the sliding shelf by pressing the release tab.
− Push the base unit into the rack until it fully retracts and locks into place.
− Secure the sliding shelf by installing the screw under the sliding shelf handle.

2 Replacing System Components
This chapter describes how to replace system components in an InterServe 8000 server.
Before You Begin
Follow the instructions in Chapter 1 for opening the unit to access the internal components.
Before replacing parts, ensure the problem has been correctly identified so that you do not
inadvertently replace a properly working part. The troubleshooting chapter in the System Setup
document delivered with the system has a list of potential problems and errors your system may exhibit.
WARNING Heed all warnings and cautions in the accessing, servicing and upgrading instructions.
Personal injury and damage to equipment can occur if documented procedures are not
followed.
CAUTION The system produces high-leakage current. Flip the circuit breaker (if included) to the OFF position
when servicing or upgrading the base unit.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge (ESD). ESD can damage components inside the system.
Floppy Disk Drive or Combo Drive
Standard hardware for the server includes a floppy disk drive in the 3.5-inch slot. If your system
contains the combo drive (containing a floppy disk drive and a PC Card adapter), it is replaced in the
same way as the floppy disk drive. However, note the difference in cables as stated in the following
instructions.
To replace the floppy disk drive or combo drive:
1. Remove both side panels. The following figure shows the floppy disk drive from the back.

2. Disconnect the floppy cable and power cable from the drive. If the combo drive is installed (not
shown), also disconnect the two ISA bus cables (not shown). Note the position of the red stripe on
the floppy cable and ISA bus cables. The cables must be installed on the new drive in the same
orientation.
3. The drive is secured to the system using a bracket that extends to the sides of the peripheral cage.
Using a quarter-inch nutdriver, remove and retain the screws (two each side) from the peripheral
cage as shown above.
4. Disconnect the SCSI cable attached to the CD-ROM drive.
5. Lift up the floppy disk drive and slide it back, then out the side of the system.

3. Slowly pull the drive out of the system. Do not let the drive fall when it clears the rails inside the
internal disk section.
NOTE The drive may continue to spin for a short duration after you remove it from the system.
4. To insert the new drive, extend the latching clips on the disk drive and align the rails on the side of
the drive with the slot guides. The metal casing of the drive faces up.
5. Push the drive between the latching clips until it slides all the way into the slot and firmly engages
the connector.
6. Close the latching clips to lock the drive in the slot.
7. Restart the system and ensure the LED for the new disk drive lights and remains steady green.
8. Label the new drive with the same ADP, CH, and ID numbers used on the replaced drive.
