SP Switch environment (MAP 0600)

6.Check the Environmental (yellow) LED for an ON or FLASHING condition.

7.Is the Environmental (yellow) LED ON or FLASHING? v If the Environmental LED is on or flashing:

a.Put the SP Switch's circuit breaker into the Off (`0') position.

b.Return to ªStep 0600-011º on page 1-7 and continue service with the next highest priority.

vIf the Environmental LED is not on or flashing:

a.You have resolved the problem.

b.Go to ªStep 0600-017º on page 1-10 to verify fix.

Step 0600-013

Perspectives indicated a shutdown temperature condition and Table 1-2 on page 1-5directed you to this step.

Temperature is out of specified range; however, no serious electrical current or fan speed problems have been detected.

1.Check for airflow blockage at air intakes and exhaust of the SP Switch and system frame. Also, check air temperatures around the frame, looking for sources of abnormally high temperatures (above 40C or 104F).

2.Is there an obvious airflow blockage or abnormally high temperature source near air intakes? v If yes, go to ªStep 0600-016º.

vIf no, go to ªStep 0600-014º.

Step 0600-014

You have an over temperature condition but you did not find an obvious airflow blockage or abnormally high temperature source near air intakes. This indicates that there is a problem in the switch supervisor card.

1.Have the customer remove the switch from the active configuration and power off the SP Switch.

2.Set the circuit breaker to the Off position. Unplug cables connected to J1 and J2 at rear of the SP Switch.

3.Remove the front panel assembly from the inner chassis.

4.Replace the switch supervisor card.

5.Perform ªSwitch supervisor self-testº on page 3-4.

6.Does the card pass self-test?

v If yes, go to ªStep 0600-015º.

vIf the card does not pass self-test, check the cable connections to the switch supervisor card. If no obvious problems are found, call next level of support.

Step 0600-015

The switch supervisor card passed the self-test.

1.Check Environmental (yellow) LED for ON or FLASHING condition.

2.Is the Environmental (yellow) LED ON or FLASHING?

vIf the Environmental LED is on or flashing, check the cable connections to the switch supervisor card. If no obvious problems are found, call next level of support.

vIf the Environmental LED is not on or flashing:

a.You have resolved the problem.

b.Go to ªStep 0600-017º on page 1-10 to verify fix.

Step 0600-016

You found an obvious airflow blockage or abnormally high temperature source near air intakes.

1. Have customer remove the switch from the active configuration and power off the SP Switch.
