Power Indication
The front panel Power LED connects directly to the unit’s power
supply. If the Power LED is not illuminated, power is not connected
to the unit, or the unit’s power supply has failed.
Boot-time LED Diagnostics
The front panel’s Status, Act 1 and Act 2 LEDs display the transition
through a sequence of codes at boot time indicating the product’s
progress through the boot process. If the boot process aborts,
terminates, or halts before the product is online and functional, the
state of the LEDs can help in diagnosing the problem. The following
table describes the startup sequence and conditions.
After restart completes, the Status LED begins to blink and LED
activity begins as described in the next section, “Runtime LED
Diagnostics.”
