steady pressure to the faceplate
and latch assemblies.
rack-mounted version,
Perform the following:
1. Holding the replacement
circuit pack vertically, rotate
the circuit pack 90 degrees to
the right (clockwise). The
faceplate LEDs should be on
your right.
2. Open the faceplate latches
and seat the replacement
circuit pack in the empty slot
