System Power-up
System Boot Process
Applying Power to the Chassis
With all power and ground cables connected, you apply power to the chassis by following the instructions below.
Caution
Never operate the chassis if any slots are uncovered. This reduces airflow through the chassis and could cause it to overheat. A card or blank panel must be installed in every chassis slot at all times.
Step 1 If the top-front cover is installed on the chassis, remove the cover to access the PFU circuit breakers. Step 2 At the front of the chassis verify that the circuit breakers on the PFUs are in the OFF position. Step 3 Set the circuit breakers on the power distribution panel (PDP) to ON. Step 4 At the rear of the chassis, remove the plastic terminal cover to access the PFU input terminals. Step 5 Use a voltmeter to check the voltage level and polarity across the input terminals for each PFU. The meter should display a voltage approximately equal to that of the power source. Step 6 Turn ON all the circuit breakers on both PFUs. Step 7 Proceed to Verifying System Startup. Step 8 When the initial checks are completed, reinstall the covers removed in step 1 and step 4.
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:As the system progresses through its boot process, LED activity will eventually occur on all cards. 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.
Checking Status LEDs on MIOs
The table below identifies the operational and transitional states for LED indicators on an MIO /UMIO card.
