CAUTION Do not touch the components as you push the VRM down into the slot.
3. Gently insert the VRM into the socket.
4. Re-install the system board assembly into the chassis.
Replacing the Power Supply Fans
The power supply fans are mounted on removable brackets just forward of the power supply cage(s). Each
bracket contains two fans. The fans are not individually replaceable; you must replace them both, and the
bracket, as a unit. These units may be hot-swapped.
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 power supply 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 cover.
6. Lift the ejection handle to release the fan bracket from the chassis. Remove the bracket from
the chassis.
