The BlackDiamond switch provides a facility for running normal or extended
diagnostics on an I/O module or a Management Switch Fabric Module (MSM) without
affecting the operation of the rest of the system.
If you select to run the diagnostic routine on an I/O module, that module is taken
off-line while the diagnostic test is performed. Traffic to and from the ports on the
module are temporarily unavailable. Once the diagnostic test is completed, the I/O
module is reset and becomes operational again.
You can run normal or extended diagnostics on the slave MSM. The normal diagnostic
routing is a short series of tests that do not test all the internal Application-Specific
Integrated Circuit (ASIC) functions. The extended diagnostic routine tests coverage of
all MSM components including the internal ASIC functions. The slave MSM is taken
off-line while the diagnostic test is performed. It is reset and operational once the test is
completed.
If you want to run the diagnostic routine on the master MSM, you must set it in
diagnostic mode and then reboot the switch. When you reboot, the master MSM
becomes the slave MSM (and vice versa) so that the diagnostic routing can be
performed.
To run the diagnostic routine, use the command
run diag [normal | extended] [<slot> | msm-a | msm-b]
where the following is true:
•
normal
— Takes the switch fabric and ports offline, and performs a simple ASIC and
packet loopback test on all ports. The test is completed in 30 seconds. CPU and
out-of-band management ports are not tested in this mode. As a result, console and
telnet access from the management port is available during this routine.

running on the switch. Displays the switch serial
