Chapter 4 Installation on Cisco 3660 Routers

Installing the Alarm Terminal Block

Follow this procedure to install the alarm terminal block (see Figure 4-10) in the Cisco 3660 router alarm port:

Step 1 Turn OFF power to the router. However, to channel ESD voltages to ground, do not unplug the power cable.

Step 2	Use 12- or 14-AWG copper wires to connect DC-input power to the terminal blocks.
Step 3	Strip the wire shielding so that approximately 0.38 in. (9.7 mm) of each wire is exposed.

Step 4 Press the orange-colored release and insert a wire into a receptacle of the alarm terminal block. Two of the three receptacles must have wires installed (see Table 4-1). The spring-loaded connector retains the wires.

Note Always wire the P terminal and one of the other (NO and NC) terminals.

Note To remove wires, press the orange-colored release next to each receptacle.

Step 5 Plug the alarm terminal block into the alarm port on the Cisco 3660 chassis. (See Figure 4-11.)

Note Connect the alarm terminal block to either an AC power source rated maximum 25 VAC and 5A current rating, or a DC power source rated maximum 30V and 5A current rating.
