Quad SIO PCA Diagnostic Procedure
This procedure assumes that the Quad SIO PCA worked at one time and has
not been replaced or settings altered by previous troubleshooting activity.
Refer to the switch settings portion of this manual for switch and jumper
options if it is suspected that they have been changed. This procedure also
assumes the user is logged into the BMC and that the BMC messages are
directed to the local terminal. No output to a local terminal will occur if the
user is not logged in or messages are directed to a DMS-10 printer. For
DMS-10 sites using the DMS-10 printer, the appropriate MSG x (x = TTY #
assigned to BMC) must precede the command entered.
Procedure 6-29
Quad SIO PCA (NT6M60xx) Diagnostic
Step Description
137
The following commands are used to list the alarms and identify the active processor.
>ERRMAP ALARMS (cr)
System responds with a list of alarms on the active and standby processors.
>CLK (cr)
System responds with a time stamp and the identity of the active processor.
Note:
The A processor is in the top shelf and the B processor is in the bottom shelf. The active
processor can also be identified by the location of the lighted green lamp on the status panel.
If the SIO alarm is on the active processor and there is no communication between the
user terminal and the BMC, go to step 2. If the user terminal can communicate to the
BMC, go to step 3.
