Procedure 7-5.
1.
Ensure that the circuit breakers that will be connected to the replaced T1100
AS chassis are still turned OFF.
To locate the circuit breakers supplying power to the T1100 AS chassis, refer to
the system interconnect diagram for the system type and/or read the labels
on the breakers. To access the circuit breakers on some frames, it may be
necessary to remove the plastic covers on the front of the breakers. If the
covers are removed, to maintain NEBS compliance, make sure they are
replaced when the FRU replacement has been completed.
WARNING: A T1100 AS chassis is redundantly powered from both A and
B -48 VDC buses. Ensure that both the circuit breaker supplying A power to
a chassis and the circuit breaker supplying B power to a T1100 AS chassis
are turned OFF by measuring the voltage with a VOM on the cable that
connects the T1100 AS chassis to its breakers.
WARNING:
frame when working on electronic components.
2.
Remove the front door and any plastic panels from the rear of the frame.
3.
From the front of the frame, extend the slide assemblies approximately 10 to
14 inches until the detent latches on the rear of the slides engage.
DANGER: Moving a T1100 AS chassis requires two people. Each T1100
AS chassis weighs approximately 30 kg (65 lbs) and may cause personnel
injury or damage to the internal components due to shock and vibration if
not handled properly.
4.
Lift the T1100 AS chassis and carefully insert the inner slide members into the
middle slide members in the frame. See Figure 7-3.
