If the power was lost during the flash PROM update, complete the power interruption recovery procedure for your system.
There are three scenarios for the Sun Enterprise 3x00, 4x00, 5x00, and 6x00 systems:
Completing the update of the flash PROM
Recovering a one-board system after power interruption
Recovering a multi-board system after power interruption
If power was interrupted during the flash PROM update procedure, it is possible that one or more system boards were not updated successfully. You must become superuser and complete the flash PROM update.
Only one board is updated at any given time in the flash PROM updating process. If there is a power interruption to the system while the flash PROMs are being updated, only one board will have its flash PROMs in an inconsistent state.
Power interruption during updating of the flash PROMs aborts the updating at the point of the power interruption. Turn the keyswitch to the Standby position (Figure 5-1) to prevent power surge to the system when power is restored.
The following recovery procedure requires another board of the same type with an uncorrupted PROM image (if you are updating an "I/O Type 1" board, you must use another "I/O Type 1" board). In the following code examples, the flash PROM on board 3 recovers by copying the flash PROM image from board 0.
Connect a null modem cable to port A and to either a terminal or a Sun(TM) Workstation(TM).
Set the serial port at 9600 bps, 8-bit word, no parity, and 1 stop bit.
Remove the board that was being programmed when the power went out.
Turn the keyswitch to the On position (Figure 5-1).
Hardware Power ON
Wait 15 seconds and type s on the keyboard terminal or the tip window connected to the serial port.

Turn the keyswitch to the Standby position (Figure 5-1). Wait 15 seconds.
Complete the procedure "To Update the Flash PROM" to reattempt the flash PROM update process.
