Connect Power Feeds to the PFUs
To avoid personal injury or possible equipment damage, ensure that the circuit breakers for all ASR 5500
chassis feeds from the power distribution panel are all set to OFF before attempting to attach power cables
to the PFU(s).
Caution
Verify that all circuit breakers on the front panels of both PFUs (four per PFU) are set to OFF before
attaching power feed cables to the PFUs (see figure below). The breakers must remain OFF until the
chassis is to be powered up.
