7.1 Using the Component LEDs
InServ S-Class Storage Server components have LEDs to indicate that the hardware is
functioning properly and to help identify errors. These LEDs serve as tools for diagnosing 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 the hardware is
functioning properly.
If you detect any problems during inspection of the LEDs, contact your 3PAR Authorized
Service Provider.
7.1.1 Removing the Bezels and Unlocking the Door
■ To view the node, drive chassis or service processor LEDs, remove the bezels.
WARNING: Hazardous energy is located behind the rear access door of the
storage server cabinet. Use caution when working with the door open.
NOTE: Front locking fascias are optionally available. If the InServ Storage Server
has locking fascia, they must be removed prior to removing the bezels. See
Figure 7-1.
