Preparing for External Connections

Following are the procedures for making external connections to the different router, access

server, and hub models.

Connections for Router Models

Figure 2-14 shows the rear panel of the single LAN router (the rear panel of the dual LAN

router is similar), with the following connectors:

1 Ethernet DB-15 (models 2501, 2503 [2503 shown], 2513, and 2514)

or Token Ring DB-9 (models 2502, 2504 [2502 shown], 2513, and 2515)

2 Serial DB-60 (2 connectors—all models)

3 BRI RJ-45 (models 2503, 2504, and 2516)

Caution To prevent damage to the system, connect the BRI cable to the BRI interface only

and not to any other RJ-45 connector. The console, auxiliary, and BRI ports all use RJ-45

connectors.
