Connecting Serial Cables to the Network Processor Module

This section describes how to connect cables to the high-speed and low-speed serial connectors at the

back of the router. It also describes the process of routing cables on the cable-support tray.

Making High-Speed Serial Connections

The two high-speed serial ports use 60-pin D-type connectors. Use the specific serial transition cable for

the module type and the correct connector (EIA/TIA-232, V.35, X.21, EIA/TIA-449, or EIA-530) for

your modem or CSU/DSU connector type.

Take the following steps to make high-speed serial connections:

Step 1 Attach the ends of your serial transition cables to the synchronous serial ports of the serial network

processor modules. (See Figure 27 and Figure 28.)

Step 2 Attach the EIA/TIA-232, V.35, X.21, EIA/TIA-449, or EIA-530 end of the cable to the CSU/DSU or

modem.

Step 3 If all your network connections are complete, proceed to the section “Connecting the Power Cord and

Switching on the Router” on page 39.

Caution Cable connector pins can be easily damaged. The high-speed serial connector is not upside down as it is

on the NP4T network interface module. Be careful of the orientation when plugging in the 60-pin cables.
