Installing Expansion Modules on Cisco High-Density Extension Modules
Installing Expansion Modules on Cisco High-Density Extension
Modules
Expansion modules can be used to increase the number of ports supported on the high-density extension
module.
Note
To install expansion modules, follow these steps:
Decide if the expansion board is going in the EM0 slot or EM1 slot.
Step 1
Note
Step 2 Align the connectors on the underside of the expansion module with the connectors for the slot you
plan to use on the network module. (See
Step 3 Using gentle pressure, insert the connectors on the underside of the expansion module into the
connectors on the network module.
Use the alignment pins on the network module brackets to guide the expansion module during

installation.
Note
For each expansion module, two mounting screws must be installed with 6-8 lbs-in (67.8 N-cm) of

torque. Failure to properly secure the expansion module to the base module with two screws
compromises product reliability. In the case of FXO ports, failure to properly tighten both mounting
screws causes FXO ground-start outgoing call operation to fail.
Step 4 Insert two screws from the hardware kit through the screw guides on the expansion module into the
threaded holes on the network module brackets.
