Installing or Replacing an ATM Module
3 Disconnect all of the optical-fiber cables from the I/O module and set them carefully
aside.
Be very careful in handling optical-fiber cables: kinks and sharp bends can
destroy or degrade the cable's ability to convey light pulses accurately.
4 Use the #1 Phillips-head screwdriver to loosen the captive screw at each end of the
I/O module front panel.
5 Grasp both ejector/injector handles and pivot them simultaneously away from each
other to unseat the module from the chassis backplane.
6 Use the ejector/injector handles to pull the module part way out of the chassis slot.
Do not touch the printed circuit board or any connector pins.
There is an EMI-preventive gasket attached to one edge of the module front
panel. To prevent diminished EMI protection, handle the module carefully and
avoid damage to this gasket.
7 Grasp the module front panel with one hand and place your other hand under the
metal card carrier to support the weight of the module. Slide the module completely
out of the chassis slot. Place the module immediately into an antistatic sack to
protect it from ESD damage and prevent dust from collecting on the module's
optical-fiber connectors.
8 Install and secure the replacement module as described in the "Inserting and
Securing a Module" on page 2-7.
9 Check your notes on the slot assignment and cable connection information that you
wrote down before removing the defective I/O module, then reconnect the network
interface cables to their assigned ports on the I/O module.
