Installing 2T16S Network Processor Modules in the Cisco 4000 Series

Figure 34 2T16S Network Processor Module

You must use a special serial transition cable to connect the Cisco 4000 series router to a modem,

CSU/DSU, or other device. This cable, which is available from your customer service representative, is

normally ordered with the system. In all, 12 different serial cables are available for the two versions of

serial modules: DTE and DCE versions of V.35, EIA/TIA-232, X.21, EIA/TIA-449 (high-speed port

only), and EIA-530 (high-speed port only). Note that the cables for the two versions are not

interchangeable.

If you need to order cables, contact Customer Service at 800 553-6387, 408 526-7208, or

cs-rep@cisco.com.

Note Serial ports configured as DCE must also be configured with the clockrate command. An error message

will be generated if there is a mismatch between the cable and the software configuration of the port—for

example, if the cable is DTE and clock rate is set, or if the cable is DCE and clock rate is not configured.

Connecting the Power Cord and Switching on the Router

Take the following steps to switch ON the router:

Step 1 If you have an AC-powered system, plug the system power cord into a 3-terminal, single-phase power

source that provides power within the acceptable range (100 to 240 VAC, 50 to 60 Hz, 3.0 to 1.5 A).

Step 2 If you have a DC-powered system, rewire the DC-input power supply (40 to 72 VDC) to the terminal

block. The proper wiring sequence is ground to ground, positive to positive, and negative to negative.

(See .)

Step 3 Turn ON the power switch. The power LED on the front should go on. (See Figure 3.)

Step 4 Check the OK LED on the right side of the front panel (see Figure 3) to verify that it goes on after a few

seconds delay when booting.
