Recovering Bios; Identifying Problems Using Status Leds - IBM Netfinity 7100 User's Reference Manual

Recovering BIOS

If the BIOS code in your server gets corrupted, such as from a power failure during a
flash update, you can recover your BIOS using the recovery boot block and a BIOS
flash diskette.
Note: You can obtain a BIOS flash diskette from one of the following sources:
The flash memory of your server contains a protected area that cannot be overwritten.
The recovery boot block is a section of code in this protected area that enables the
server to start up and to read a flash diskette. The flash utility recovers the system
BIOS from the BIOS recovery files on the diskette.
To recover the BIOS:
1. Turn off the server and peripheral devices and disconnect all external cables and
2. Locate jumper J56 on the processor board. See "Component locations" on page
3. Move J56 to pins 1 and 2 to enable BIOS recovery mode.
4. Insert the BIOS flash diskette into the diskette drive.
5. Restart the server.
6. Remove the flash diskette from the diskette drive.
7. Turn off the server.
8. Move J56 to pins 2 and 3 to return to normal startup mode.
9. Restart the server. The system should start up normally.

Identifying problems using status LEDs

Your server has LEDs to help you identify problems with some server components.
These LEDs are part of the light path diagnostics built into the server. By following the
path you can quickly identify the type of system error that occurred.
Status LEDs are located on the following components:
