Replacing FRUs in a Spare CGR Chassis
Detailed Steps to Replace the Chassis
2.
Remove the corresponding antenna or N-connector from the old chassis. The antennas can be removed with a strap
wrench or bare hands. The N-connector cap
threads as shown in
3.
Use the ½-inch (13mm) socket wrench to remove the appropriate plugs of the ports 3, 4, and/or 5 of the new
chassis. Refer to
Note: This step can be skipped when removing the modules from slots 5 & 6. For port 5, make sure to move the
10.5" cable away from the BBU cable before removing the MCX connector.
4.
Insert the antenna and/or N-connector to the new (spare) chassis at the same locations. The same tools in step 2
will be used at any torque in between 6-7 lbs-ft. If necessary, refer to the
5.
Remove module from the appropriate slot of the old chassis. Use the #1 Phillips screwdriver to loosen the captive
screws next to the handles of the module. Cut zip tie from the handle of the module only if the RF cable is routed
from the back of the router (only applies to slot 5 & 6). Grip the module just enough to pull it out of the PCI connector
and the slot.
6.
Remove the blank module from the corresponding slot of the new chassis.
7.
