6.5.6.2 Forcing a Fail-Safe Floppy Load

Under some circumstances, you may need to force the activation of the FSL. For example, if
you install a system motherboard that has an older version of the firmware than your system
requires, you may not be able to bring up the SRM console. In that case you need to force a
floppy load so that you can update the SRM firmware.
1. Perform a normal system power down.
2. Extend the chassis for service.
3. Remove the top cover, to gain access to the system motherboard.
4. Remove MMB 1 (closest to the PCI motherboard) so that you can access the function
jumpers. See Figure 6-1.
5. Insert the Firmware Update Utility diskette and perform the update.
6. Locate the J22 function jumper on the system motherboard. See Figure 6-1.
7. Enable the fail-safe loader by moving the J22 jumper from pins 1 and 2 to pins 2 and 3.
_____________________________ Note____________________________
The J20 and J23 function jumpers must be in their default positions on pins 1 and 2.

8. Replace MMB 1 and the top cover.
9. Turn on the system and check the control panel display for progress messages. Enter "yes"
at the UPD> prompt.
10. After the update utility has finished, perform a normal system power down.
11. Remove the top cover and MMB 1.
12. Move the J22 jumper back to pins 1 and 2.
13. Replace MMB 1 and the top cover.
14. Turn the system back on. The system should power up to the P00>>> console prompt.
