3b. If the status shows:  "Ok"  Go to Step 5

4. Validate the existence of a StorADE Alarm against the PCU by logging into the Storage Automated Diagnostic Environment (StorADE) using one of the following procedures:

use the following URL:   https://system_ip_address:7443

From the "Home" window that comes up, check the "Device Health Summary" to see if there are alerts listed. To verify that an alarm is related to a PCU issue, select the "Alerts" link in the "Device Health Summary" and search for PCU alarms. Selecting the alarm link will display details about the alarm.

• If status is ready-enabled, and there is no fault LED on the PSU, clear the alarm, as the PSU is optimal.
• If status is ready-enabled, and the PCU has a fault LED, check the battery state.  Reference <Document: 1019955.1> Troubleshooting Sun StorEdge[TM] 6320 Battery Faults.
• If status is ready-disabled, check power cable, switch, and AC output. See section B.6 of the Sun StorEdge 6320 System 1.2 Reference and Service Manual for details on power cable requirements.
• If status is fault-enabled output=fault, the PCU requires replacement due to a problem with the DC output to the array.  Collect the following and open a Service Request with Sun Microsystems to have the PCU replaced.

    * Storade alarm
    * Email (alarm from storade)
    * Cut and paste of fru report

• If the status is fault-enabled output=fault, and the PCU has already been replaced, the battery may require replacement.  Reference <Document: 1019955.1> Troubleshooting Sun StorEdge[TM] 6320 Battery Faults.
  
• Otherwise go to Step 6.

6.  At this point you have validated the PCU status on your 6320 array, and require further assistance.  Please contact Sun Services.
