Troubleshooting Your System
AlphaServer 1000 Rackmount Owner's Guide 8-17
Using the Fail-Safe Loader
The fail-safe loader (FSL) allows you to boot an Update Utility diskette in an attempt to
repair corrupted console files that reside within the FlashROMs on the system board. Use
the FSL only when a failure at startup prevents you from accessing the console mode.
Using the Update Utility
If a checksum error is detected when loading the console at startup, the system
automatically loads the Update Utility from diskette into memory.
To activate FSL:
1.
Turn off the system.
2.
Install the update utility diskette into the diskette drive.
3.
Remove the top cover (See "Removing Top and Side Panels" in Chapter 5, "Installing
and Removing Components").
4.
Enable FSL by moving the jumper on the CPU card to the position nearest the system
board (see Figure 8–1).
5.
Replace the top cover and side panels.
6.
Turn on the system and confirm the update:
>>> show version
7.
Turn off the system.
8.
Remove the top and side panels.
9.
Disable the FSL and set the SROM jumpers to their normal operating position.
10. Replace the top cover and side panels.
