CAUTION
Establish a ground by first touching the metal chassis of the cabinet before handling or
installing computer components.
To replace a disk drive:
1. Remove the new disk drive from its packaging and antistatic bag. Save the packaging
material.
2. Note the drive label on the failed disk drive. Remove the matching numbers from the
label sheet and affix them to the front of the new disk drive.
3. Extend the drive latching clips to disengage the failed drive from the disk array; then
slide the disk drive out of the cabinet.
4. Install the new disk drive by extending the drive latching clips and sliding the disk drive
into the drive slot. Place your thumb on the drive label and push the drive in until it
connects. Close the drive latching clips until they snap into place, locking the drive into
the slot.
Using the packaging materials from the replacement disk drive, repackage the failed drive
and return it to Intergraph Computer Systems. Refer to “Returning Equipment to Intergraph
Computer Systems” in Chapter 1.
Replacing Power Supplies
The InterRAID-8e has hot-swap power supplies. You do not have to turn off power to the
InterRAID-8e cabinet to replace a power supply.
When inserting a power supply into a system,
push it in completely until fully seated. Close
the extraction lever. If the power supply does not power on, pull the power supply out, wait
at least 45 seconds, and push it back into place. The DC OK LED on the back of the power
supply illuminates to indicate that the power supply has powered on.
If using devices that require excessive power, you must add a third power supply to maintain
redundant operation. The cabinet is currently limited to 13 watts power consumption per
slot for redundancy. A third power supply will increase this to 30 watts.
To replace a power supply:
1. Locate the failed power supply at the back of the cabinet. The LED for a failed power
supply will be unlit.
2. If replacing power supply 3, use a flat-blade screwdriver to loosen the power supply
cover screws. Open the power supply 3 bay.
If installing a new power supply in bay 3, remove the grommet from the LED opening in
the power supply cover.
