SCSI SWITCH (FOR AS/400
®
)
If any error occurs while loading the microcode from tape:
• “Ld ERROR” flashes indefinitely on the tape unit’s front panel until power
to the SCSI Switch is turned off.
• The SCSI Switch’s monitor is entered for error recovery. Refer to the
Appendix
to use the monitor.
To retry the microcode load operation without using the monitor, follow
these steps:
1. Power off the SCSI Switch and wait a few seconds.
2. Power on the SCSI Switch.
3. Go to step 6 of the normal microcode load procedure.
The most common reason for microcode load failures is that an invalid
microcode tape is loaded into the tape unit. Make sure that a valid
microcode tape is loaded. If the switch still is unable to load microcode from
a microcode tape, call for technical support. The tape could be bad or there
could be an internal SCSI Switch controller fault.
