6 Troubleshooting
If it is clear that a particular component system is at fault in a problem situation, go directly to that component.
If it is not clear, the best approach is to troubleshoot using the inside-out method.
You may check on the status of your iPBridge
using the ExpressNAV interface. You may also
look for information by using the diagnostic CLI
commands, enumerated in CLI provides an
ASCII-based interface on page iii, in the
Advanced page of the ExpressNAV interface or
by using the CLI directly.
To start and use the ExpressNAV interface,
including how to access the version information,
refer to Opening an ExpressNAV session on
page 23.
Inside out method
To troubleshoot using the inside out method, begin with the device(s) connected to the iPBridge first,
then work your way out.

when the iPBridge is ready and blinks steadily
when there is SCSI activity.
