Installing Cable Management Frames onto the Chassis
Step 5
Install four cables (two positive and two negative cables) in the four terminal slots as follows:
a) Unscrew the two nuts in each of the four terminal slots.
b) Attach and crimp each lug to the end of each power cable.
c) Attach each cable lug to the two terminal posts in each slot, fasten with two nuts, and tighten to 40 in-lb (4.5 N·m).
For all your power connections, if you are using cables with two different colors, use one color cable for all
Note
positive circuits and the other color for all negative circuits.
d) Replace the safety cover on the terminal box and fasten with three screws.
Step 6
Install the four cables from the DC power supply to a DC power source as follows:
a) If the unconnected end of each power cable is not stripped of its insulation for the last 0.75 inches (19 mm), use wire
strippers to remove that amount of insulation.
b) Attach the negative cables to the negative terminals of a DC power source, and attach the positive cables to the
positive terminals of the same power source.
Note
If you are using combined power mode or power supply redundancy mode, connect all the power supplies
in the chassis to the same power source. If you are using input source redundancy mode or full redundancy
mode, connect half the power supplies to one DC power source and the other half of the power supplies to
another DC power source.
Step 7
For the powered down circuits connected to the power supplies, turn on the power at the circuit breaker. The Input 1
(IN1) and Input 2 (IN2) LEDs turn on each connected power supply.
Step 8
Turn on the power supply by setting the power switch to 1. The LEDs should flash and then the Output LED should turn
on in addition to the Input LEDs.
If the FAULT LED is lit or flashing, call Cisco TAC for assistance.
What to Do Next
You are ready to connect the switch to the network.
