▀ Verifying System Startup

Verifying System Startup
When power is applied to the chassis, power is provided to the upper and lower fan trays, and every installed card.
Light emitting diodes (LEDs) on all circuit cards and daughter cards indicate operating status.
Important:
Allow several minutes to elapse prior to checking the status LEDs on the various cards.
Checking PFU Status
The blue LEDs above the circuit breakers on each PFU should all be ON.
If all of the LEDs on a PFU are OFF, check the following:
 The PFU is firmly seated in the midplane connectors.
 All circuit breakers on the PFU are set to ON.
 All circuit breakers for power feeds from the local power distribution panel are ON.
 -48 VDC power is available from the PDF to the local PDP.
If any LED is OFF, check the following:
 PFU circuit breaker is ON.
 Voltage is present at corresponding input terminal at rear of the PFU.
 Cable connection at PFU terminals is secure.
 Circuit breaker for the power feed from the local PDP is ON.
 Cable connection at the PDP terminal is secure.
