Procedure steps
1 At the rear of the frame, locate the alarm/BITS module. See the figure
"Location of the alarm/BITS module and cable connections in a
Passport 15000" (page 818)
2 Disconnect the alarm and BITS cables from the alarm/BITS module.
3 Cut the seal when instructed by Nortel Networks technical support.
4 Unfasten the large slotted captive screw or screws on the alarm/BITS
module.
5 Remove the module by firmly pinching the U-shaped handle and gently
pulling straight away from the switch.
6 Put the module aside.
7 Hold the replacement module firmly so that the U-shaped handle is facing
you and the captive screw is at your left.
8 Align the module with the vacant opening and then align the connector on
the module with the connector at the rear of the opening.
Removing the Passport 15000 fabric X allows you to see the module
connector by looking down through the chassis. See the figure "Proper
alignment of an alarm/BITS module in a Passport 15000" (page 816). If
the module is not aligned properly the connector on the module will not fit
flush with the connector on the chassis.
