Symptoms

A failed FAN TRAY must be replaced to insure proper platform operation.

Cause

Each of the members of the Highend Platform Family(12K/15K/E20K/E25K) contain FAN TRAYS.
On detection of a Fan failure, you must contact your authorized Sun[TM] Service representative to have any failed FAN TRAY replaced.

Solution

The SMS "showenvironments" command will display the status of the FAN TRAYS. Partial output from this command is contained in the example below:
Note: All command output may vary slightly depending on type of platform.
