This chapter provides removal and replacement procedures for VCO/4K I/O Modules. For additional information and detailed specifications for each I/O module, refer to the Cisco VCO/4K Card Technical Descriptions.
Follow these steps to remove an I/O module.
Step 1 Take the port interface cards, in the module locations, out-of-service (OOS). For information about taking cards OOS, refer to the Cisco VCO/4K System Administrator's Guide.
Step 2 From the back of the system, unscrew the top and bottom fasteners for the card.
 |
Note The same mounting hardware is used for all I/O module assemblies. |
Step 3 Pull the module away from the backplane.
 |
Caution Do not attempt to pry the I/O module from the backplane using a screwdriver or some other tool. The tip of the prying tool could damage the backplane and/or DIN connectors. |
Follow these steps to replace or add an I/O module:
Step 1 Press the module firmly into the DIN connectors on the backplane.
Step 2 Tighten the mounting screws.
Step 3 Make the appropriate network connection to the module.
|
Note Verify that the system database entries correspond to the type of module and port interface cards installed at the adapter's R-L-S locations. |
|
Note More extensive troubleshooting information is contained in the Cisco VCO/4K Troubleshooting Guide. |
If problems occur with the network interface, check all cable and cross-wiring connections. Examine a suspect module for signs of physical damage (cracked connectors, damaged wires, etc.). Correct the cause of the damage by reconnecting network cables and cross-wiring and/or rerouting cables to avoid future problems.
