Cisco Interface Cards Installation Guide

A Cisco 3745 router includes four slots in which you can install network modules.

Each pair of slots can be combined to accommodate a double-width network

module. The slot numbers are as follows:

• 1 for interfaces in the lower-right network module slot

• 2 for interfaces in the lower-left network module slot

• 3 for interfaces in the upper-right network module slot

• 4 for interfaces in the upper-left network module slot

• 2 for interfaces in the lower double-width slot

• 4 for interfaces in the upper double-width slot

Port Numbering

Port numbers begin at 0 for each slot, and continue from right to left and (if

necessary) from bottom to top. Network modules and interface cards are

identified by interface type, slot number, a forward slash (/), and the port number;

for example, Fast Ethernet 0/0.

Figure 1-3 shows an example of interface numbering on a Cisco 3725 router with

the following configuration:

• A WAN interface card (WIC) in each WIC slot

• A 2-port T1 network module in slot 1 (containing the following ports: T1 1/0

and T1 1/1)

• A 36-port Ethernet switch network module in slot 2 (containing the following

ports: Fast Ethernet 2/0 through 2/35, and Gigabit Ethernet 2/0 and 2/1)

• Two built-in Ethernet 10/100 interfaces—Fast Ethernet 0/0 and Fast Ethernet

0/1
