FRU Removal and Replacement

The procedures in this section describe how to remove
system unit FRUs. Observe any notices and prerequi-
sites for removing a FRU. Replacement is the reverse
of removal, unless noted.
1 Power off the system, the monitor, and any peripheral
devices.
There is no need to manually shut down the HP-
UX operating system on the workstation before
powering it off with the power switch. When the
power switch is turned off, the workstation
automatically shuts down the operating system
before terminating the power.
Unplugging the power cord while HP-UX is
running can damage the system files.
2 When the system has completely shut down and powered
off, unplug the system unit power cord and the power
cords of any peripheral devices from ac wall outlets.
3 Unplug the system unit power cord from the ac input
connector.
4 Disconnect any external cables from the connectors on
the front and rear of the system unit.
5 Attach a static-grounding wrist strap to your wrist and a
location on the system chassis that is bare metal. If you
are using a disposable wrist strap, follow the instructions
on the package.
6 If installed, remove the floor stand as shown in
Figure 18.
