MAP 5400: Front panel

MAP 5400: Front panel helps you to solve problems that have occurred on the SAN Volume Controller front panel.

If you are not familiar with these maintenance analysis procedures (MAPs), first read Using the maintenance analysis procedures.

This MAP applies to all SAN Volume Controller models. Be sure that you know which model you are using before you start this procedure. To determine which model you are working with, look for the label that identifies the model type on the front of the node.

You might have been sent here because:

A problem occurred during the installation of a SAN Volume Controller system, the front panel display test failed, or the correct node number failed to be displayed
Another MAP sent you here

Perform the following steps:

For a SAN Volume Controller 2145-4F2, is the power-on indicator on the front panel illuminated and showing a solid green LED or, for other models, is the power LED on the operator-information panel illuminated and showing a solid green?

NO

Continue with the power MAP.

YES

Go to step 2.
(from step 1)
Is the service controller check indicator that you see in Figure 1 illuminated and showing a solid amber?

The front panel check light illuminates and the display test of all display bits turns on for 3 seconds and then turns off for 3 seconds, then a vertical line travels from left to right, followed by a horizontal line travelling from top to bottom. The test completes with the switch test display of a single rectangle in the center of the display.
Did the front panel lights and display operate as described?
NO
SAN Volume Controller front panel has failed its display test.
