Removing the NAM
Note
If the NAM does not respond to any commands from the NAM prompt or the supervisor
engine, use a small, pointed object to access the recessed SHUTDOWN button located on
the NAM faceplate.
Note
The shutdown process may require several minutes to complete.
Removing the NAM from the Chassis
To remove the NAM from the chassis, follow these steps:
Step 1
Verify that the NAM has shut down. Do not remove the NAM from the switch until the NAM STATUS
LED is off or is orange.
Step 2
Attach an ESD wrist strap to yourself and to earth ground.
Step 3
Verify that the captive installation screws on all of the modules in the chassis are tight.
This action ensures that the space created by the removed NAM is maintained.
Note
If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on
the installed modules will push the modules toward the open slot, reducing the opening size and
making it difficult to install the NAM.
Step 4
Loosen the two captive installation screws on the NAM.
Step 5
Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the
following sets of steps:
Horizontal slots
a.
Place your thumbs on the left and right ejector levers, and simultaneously rotate the levers outward
to unseat the NAM from the backplane connector.
b.
Grasp the front edge of the NAM and slide the module part of the way out of the slot. Place your
other hand under the NAM to support the weight of the module. Do not touch the NAM circuitry.
Vertical slots
a.
Place your thumbs on the ejector levers located at the top and bottom of the NAM, and
simultaneously rotate the levers outward to unseat the NAM from the backplane connector.
b.
Grasp the edges of the NAM, and slide the module straight out of the slot. Do not touch the NAM
circuitry. Only touch the NAM front panel or the NAM metal carrier.
Step 6
Place the NAM on an antistatic mat that is connected to earth ground.
