9.1 Using the Component LEDs
InServ 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.
