Using the Status LEDs to Monitor the System
Status LEDs on the various enclosures and system components light during certain operations, such
as when the system performs a series of power-on self-tests (POSTs) when a system is first powered
on. Table 11 lists some of the status light-emitting diodes (LEDs) and their functions.
Table 11 Status LEDs and Their Functions

When this occurs, verify the loop and replace the
drive, if necessary.
AmberDrive Failure
