Chapter 6 Replacing Parts

CAUTION Do not run this NetServer for more than 60 minutes without all covers in place. Any

component being replaced must be removed and a replacement installed within this

60-minute time window. If you feel that you cannot, in your estimate, replace any

particular component within this time, first turn off power to the system and then

replace the component. Failure to replace the covers within 60 minutes may result in

damage to system components due to lack of cooling air.

Follow these instructions to remove and replace the processor fans:

1. Back up the hard disk drive(s) and save the configuration.

2. If necessary, shutdown the network operating system.

3. Turn off the HP NetServer and display.

4. Disconnect all telephone cables and power cords.

5. Remove the right side cover (HP NetServer LH 6000) or the bottom cover (HP NetServer LH

6000r).

6. Remove the individual fan assembly by pressing the handles and pulling the assembly out of

the chassis.

Removing a Processor Fan
