Switch Description and Problem Determination (MAP 0590)

Yellow (Environment) LED

Off No environmental problems detected by switch supervisor card.

On Warning of environmental condition out of nominal range. Preventative Maintenance should be scheduled for this switch.

Flashing

Serious environmental condition detected; power shut off.

Green (Power) LED

Off No 48 V dc power available at switch assembly.

Flashing

Power available at switch assembly, but switch logic is Off.

On Power available at switch assembly, and logic is On.

Note: Refer to ªService position proceduresº on page 3-10 for placing or removing the switch assembly into or from service position.

Step 0590-001

Read the following warning and then follow steps to ensure continuity of customer's jobs in the queue.

Attention: Servicing a processor node or switch assembly will interrupt customer usage of the processor node and the remainder of the switch network. If the switch feature must be replaced in a multi-frame system, refer to ªRemoving and restoring switch resourcesº on page 3-9, for information on isolating the switch assembly.

Attention: It is possible that the SP Switch2 cabling has been modified from recommended or documented configurations. Any connector jack numbers will be correct as reported by system programs, so tracing cables from the jack may be necessary.

It may be necessary for the customer to complete all active parallel jobs or jobs using switch interface (for example, tape B/U ADSM), then remove the switch feature from the active configuration. Refer to ªRemoving and restoring switch resourcesº on page 3-9, for these procedures.

Step 0590-002

Determine the condition of the switch by viewing its LEDs and the information displayed in Perspectives. Then refer to Table 1-1 on page 1-5for a prioritized list of conditions. Find the first condition that describes your problem, then perform the associated action.

Step 0590-003

Check for errors indicating environmental problems with the switch feature. These can be viewed by issuing the appropriate command from the control workstation:

verrpt -a -N sphwlog pg

verrpt -a -N css0

verrpt -a -N Worm

vRefer to the ″Starting a service call (MAP 0100)″ in RS/6000 SP: System Service Guide for more information on the pg command
