problem-solving tips and for HP support telephone numbers.
If you suspect your server/tower hardware is faulty, the fault
must be isolated to one of the components that can be replaced
by Hewlett-Packard Company:
•
An HP CD-ROM drive for HP towers
•
The server module
•
The tower, that is, all the other hardware components
The previous sections of this "Troubleshooting" chapter can help
you isolate the problem to hardware. Call HP telephone support
for help in definitively isolating the fault. To perform the
replacement of a component that is determined to be faulty,
proceed with replacement procedures in the following section.
Opening the Tower
1. Switch off power to the tower (using the switch on the front).
2. Use the key to unlock the front cover. The cover is locked when
the key index points to the right. The cover is unlocked when
the key index points up.
3. Place both of your hands on the top two corners of the front
cover and carefully pull it towards you. The cover remains
attached at the bottom. See the illustration on the next page.
4. You can now remove the front cover by lifting it up, making
sure that the flange at the bottom of the cover has cleared the
opening of the tower casing. Set the front cover aside.
