On a single PA-A3-IMA all eight RJ-45 connections can be used as ATM connections, or a combination of two or more can be used as links in an IMA group. To meet VCCI Class II EMI requirements, you must use shielded twisted-pair cables with RJ-45 connectors.
To connect the shielded twisted-pair cables to the PA-A3-IMA for use as an ATM interface, follow these steps:
Step 1 Attach the shielded twisted-pair cable directly to one of the RJ-45 ports on the PA-A3-IMA.
Step 2 Attach the network end of your shielded twisted-pair cable to your external equipment.
Step 3 Repeat Step 1 and Step 2 for each of the remaining ATM interfaces you want to install.
To connect the shielded twisted-pair cables to the PA-A3-IMA as a link in an IMA group, proceed as follows:
Step 1 Configure the IMA groups on both routers. (See the "Configuring Ports on the PA-A3-IMA" section to determine which ports on the PA-A3-IMA will be connected as IMA links).
Step 2 Attach the shielded twisted-pair cable directly to the first RJ-45 port of the PA-A3-IMA that is to be configured as an IMA link in an IMA group. (See Figure 4-1.)
Step 3 Attach the other end of the shielded twisted-pair cable to the first port of the router on the far end of the IMA group.
Step 4 Repeat Step 2 and Step 3 for each of the remaining IMA links in the IMA group.
This completes the procedure for attaching a PA-A3-IMA ATM cable. Proceed to "Configuring the PA-A3-IMA," for information on how to configure your port adapter.
