6.1 Using the Component LEDs
InServ T-Class Storage Server components have LEDs to indicate that the hardware is
functioning properly and to help identify errors. These LEDs help diagnose basic hardware
problems.
You can quickly identify hardware problems by simply examining the LEDs on all the
components. Use the tables and diagrams in the following sections to verify that the hardware
is functioning properly.
If you detect any problems during inspection of the LEDs, contact your 3PAR Authorized
Service Provider.
6.1.1 Removing the Bezels and Unlocking the Door
■ To view the node, drive chassis or service processor LEDs, remove the bezels.
■ To view the power supply, battery or PDU LEDs, open the rear door by unlatching the three
latches of the door (S800 InServ Storage Servers contain PDUs in the front and rear of the
cabinet).
6.1.2 Drive Cage LEDs
The T-Class InServ Storage Server uses a DC4 drive chassis that holds one DC4 drive cage
housing two drive cage FC-AL modules and a maximum of ten drive magazines. See Figure 6-1.
WARNING: Hazardous energy is located behind the rear access door of the
storage server cabinet. Use caution when working with the door open.
NOTE: If your 3PAR cabinet has locking fascias, you must first remove the fascias
to access the server bezel.
NOTE: Many LEDs are visible without removing the bezels. To view the power
supply, battery or PDU LEDs, open the rear door of the cabinet.
