Chapter 2 Replacing Cards in the Cisco 3230 ISR Rugged Enclosure
Card Replacement Process
Step 3 If antenna cables are present, label the cables.
Every Wireless Mobile Interface Card (WMIC) has two antenna cables, primary (P) and secondary (S),
connected to the end cap. Labeling the cables will be useful later when you reconnect them to the end
cap. Labels help you determine which ports on the antenna end cap you should connect the cables to.
Use the labels on the exterior of the antenna end cap for reference. Figure 2-3 shows an antenna end cap
for a rugged enclosure with three Wireless Mobile Interface Cards (WMICs), as indicated by the six
labels ((2) for each WMIC) on the end cap exterior.
Figure 2-3 Antenna End Cap Labels
If the rugged enclosure contains only one WMIC, the WMIC Primary and Secondary antenna cables are
connected to ports W1 (P) and W1 (S).
If WMIC 2 is also present, its primary and secondary cables are connected to W2 (P) and W2 (S).
If the rugged enclosure contains the maximum number of WMICs (3 WMICs), the primary and
secondary cables of WMIC 3 are connected to W3 (P) and W3 (S).
Step 4 If antenna cables are present, disconnect them from the end cap.
Step 5 Place the end cap on your work surface.
Step 6 Disconnect the power cable from the MRPC card.
