System POST

When the unit is powered on, the system first runs a Power-On Self

Test (POST) as a check of system components. Errors encountered

during the POST are indicated by different flashing front panel LED

combinations.

Note:

The LEDs flash as a normal part of the

system initialization. The error flash codes

listed in the table below will be constant and

thus unlike the brief LED indications at initial

power-on.
