3.3 Module Replacement
Use the following procedure to replace the UDC module.
Step 1. Stop any application tasks that may be running.
Step 2. Turn off power to the system. All power to the rack, as well as all power to the
wiring leading to the rack, should be off.
Step 3. Disconnect the METER PORTS plug connector.
Step 4. Disconnect the fiber-optic cables. Replace the dust cover caps on the
module’s COMM ports and fiber-optic cable connectors.
Step 5. Use a screwdriver to loosen the screws that hold the module in the rack. Take
the module out of the slot in the rack and place it in an anti-static bag.
Step 6. Take the new module out of its shipping container. Take it out of the anti-static
bag, being careful not to touch the connectors on the back of the module.
Save the anti-static bag in a safe place. The module must be stored in an
anti-static bag whenever it is not installed in the rack.
Step 7. Insert the module into the rack, making sure it is well seated in the rack.
Tighten the screws that hold the module to the rack.
