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.
