Hardware Maintenance Procedures

NOTE: To ensure that the switch will work with the previously established network configuration, the relative position of the network modules must not change when you transfer them to the new fabric. For example, an OC-3c network module that is removed from slot A of the old switch fabric must be installed in slot A of the new switch fabric. Therefore, it is recommended that you label all network connections and network modules before removing them.

NOTE: To maintain your CDB, the SCP must be removed before the network modules are removed and it must be installed in the new fabric after the network modules have been installed.

1.Log out of all open AMI sessions on the switch board that is to be replaced.

2.Remove the SCP from the old switch board using the instructions found in Section 3.4, Switch Control Processor Replacement. Place the SCP on a clean, static-free work area.

3.Label and remove all fibers or coaxial cables connected to the ports on the switch board that is to be replaced. Then label and remove all network modules from the old switch board using the instructions found in Section 3.1, Network Module Replacement. Place the network modules on a clean, static-free work area.

4.Unscrew the retaining screws at the top and bottom of the switch board with a 3/32-inch Allen wrench. On an SFCS-1000, press the top black locking tab up towards the top and bottom black locking tab down towards the bottom of the chassis until they are parallel with the front panel of the switch.

5.Using the tabs as a handle, pull the switch board out of the chassis.
