Before You Begin
WARNING Disconnect the system and peripheral devices 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 the servicing instructions. If you fail to
follow documented procedures, personal injury and damage to equipment can
result.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of
electrostatic discharge.
“Right side” and “left side” are as seen from the front of the unit.
Tools
You will need the following tools to service the system:
♦Antistatic wrist strap

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 internal components.
♦Unplug the unit from AC power before servicing any electronic component inside the chassis.
♦Touch the bare metal of the base unit to ensure the base unit and your body are at the same
electric potential.
♦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.
♦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.

3
♦Attach an antistatic wrist strap to any bare metal part of the base unit. The metal conductor in
the elastic sleeve of reusable antistatic straps must contact bare skin.
Opening the Base Unit
WARNING Before you open the base unit, shut down the system and turn off power to the
system and external devices (including peripheral devices and the monitor).
Use caution to avoid injury when removing covers and other hardware.
WARNING The service and upgrade instructions should be performed by qualified
personnel only. Qualified personnel do not have to be Intergraph service
personnel. Qualified personnel can include those who are familiar with
servicing computers, can follow instructions in a manual to service equipment,
and can do so without harm to themselves or damage to the equipment.
NOTE The InterServe 90 is designed for rack-mount or deskside use.
CAUTION To open the base unit when rack-mounted, ensure the front and side stabilizers of
the rack in which the system is mounted are fully extended.
To open the base unit:
1. Remove the screws that secure the handles to the rack.
2. Disconnect all cables including the power cable, monitor, and all peripheral cables from the
back of the unit.
3. Slide the base unit out of the rack until it locks in the extended position.

Latching Clips
Drive 0
To replace a disk drive in the disk drive bay:
1. Open the disk drive bay door on the front of the system.
2. Flip the drive’s latching clips outward to disengage the disk drive. Wait 30 seconds to allow
the drive to spin down and park the heads.
3. Carefully eject the drive completely from the rails, and remove it from the disk drive bay.
WARNING Handling a spinning disk drive or mishandling a removed disk drive can cause
the heads to crash! Subsequent failures may not be noticeable for three to six
months. Handle disk drives carefully to avoid damage.
4. Remove the drive mounting plate from the removed disk drive, making sure to retain the
mounting plate screws. Attach the mounting plate to the bottom (circuit board side) of the
new drive, using the four screws you retained from the removed drive.
WARNING Removing and attaching the drive mounting plate requires careful handling to
avoid contact with the delicate, electrostatic-sensitive parts on the circuit
board of the disk drive. Handle disk drives carefully to prevent failure and
voiding the warranty for the drives.
5. To insert the new drive, extend the latching clips on the drive and align the rails on the sides
of the drive with the slot guides in the disk drive bay. The metal casing of the drive faces left.
6. With your thumb, push the mounting plate at the center between the latching clips until it
slides all the way into the slot and firmly engages the connector.
7. Close the latching clips to lock the drive in the slot.
