Chapter 3 Installing the IGX
Installing a URM
Connecting an NTM E1 or Subrate Trunk
The E1 trunk connections use the NTM front card and the BC-E1 back card. Subrate E1 connections use
the NTM front card and the BC-SR back card. The E1 trunk interface card BC-E1 contains the E1 trunk
connector (G.703 Input/Output) that is located at the top of the back card. The BC-E1 faceplate has four
75-ohm BNC connectors.
Note The BC-E1 faceplate provides two connector arrangements for attaching E1 lines. Use either the two
BNC (RX and TX) connectors or the 15-pin DB connector.
Make the E1 connections as follows:
Step 1 Bring each E1 BNC patch cable (or 15-pin cable) through the opening at the top or bottom of the cabinet
(whichever applies) and along the back of the unit.
Note Some versions of the BC-E1 use a metal BNC connector instead of a plastic BNC. For
terminating 75- or 120-ohm balanced E1 lines at the metal BNC connectors, remove the BNC
mounting nuts. This removes the ground that normally appears on one side of the connector
shell.
Step 2 Use the cable management feature to help route the cables.
Step 3 Connect the cables to connectors on the BC-E1s that are part of an NTM/BC-E1 card sets.
Record the slot numbers of the NTM/BC-E1 card set. You need these numbers when you configure the
system.
Installing a URM
The universal router module (URM) is a dual-processor card, featuring both a modified
Cisco IGX 8400 series UXM-E processor and a modified Cisco 3660 modular-access router processor.
Each processor uses a different operating system. See documentation for both Cisco IOS software and
switch software while working with the URM.
For more information on the URM, see the Cisco IGX 8400 Series Provisioning Guide.
Installing the Encryption Advanced Interface Module
The following procedure describes the installation of an encryption advanced interface module (AIM)
module on the URM front card. This encryption AIM module is required for implementation of a virtual
private network (VPN) using the IGX.
Timesaver To avoid having to redo tasks, install the encryption AIM on the URM front card before installing the
URM in the IGX chassis.
