MAP 5400: Front panel

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

Before you begin

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

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?
