Installing the Ground Lug

Warning

Before performing any of the following procedures, ensure that power is removed from the DC

circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services

the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the

circuit breaker in the OFF position. To see translations of the warnings that appear in this

publication, refer to the Regulatory Compliance and Safety Information document that

accompanied this device.

Step 2 Strip one end of the 6-AWG wire to expose approximately 0.75 in. (20 mm).

Step 3 Crimp the ground lug around the wire. (See Figure 4-7.)

Figure 4-7 Crimping the Lug Around the Wire

Step 4 Use the number 2 Phillips screwdriver to fasten the ground lug to the Cisco 3660 router chassis. (See

Figure 4-8.)

Step 5 Connect the other end of the ground lug wire to a grounding point at your site.

Making Network Connections

Note If you still need to install network modules or WAN interface cards, you can do so now. For

instructions, see these publications: Cisco 3600 Series Hardware Installation Guide, Cisco Network

Modules Hardware Installation Guide, Cisco WAN Interface Cards Hardware Installation Guide.

You can access these documents online and on the documentation CD-ROM that you received with

your router at: Cisco Product Documentation > Access Servers and Access Routers > Modular

Access Routers > Cisco 3600 Series Routers > Hardware installation documents for Cisco 3600

series

Reinstall network cables and turn ON power to the router.

Note The shielded cables in your NEBS/ETSI kit replace the cables originally shipped with your router.

Caution NEBS/ETSI Intrabuilding Lightning Requirement

This equipment is suitable for connection to intrabuilding or nonexposed wiring or cabling only. This

cabling must be shielded.

Installing the Alarm Terminal Block

The following warning applies to routers that use a DC power supply:

Warning

After wiring the DC power supply, remove the tape from the circuit breaker switch handle and

reinstate power by moving the handle of the circuit breaker to the ON position. To see translations

of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety

Information document that accompanied this device.

Installing the Alarm Terminal Block

The alarm port on the Cisco 3660 rear panel (see Figure 4-9) provides relay outputs to connect the router

to a remote alarm.

Figure 4-9 Alarm Port on the Cisco 3660 Router

The terminals are described in Table 4-1. In order to operate the alarm port, wire the P terminal and one

of the other terminals (NO and NC).

Terminal Meaning

P Primary—This pin is connected to the common contact of the alarm relay.

NO Normally open—This pin is connected to the “normally open” contact of the alarm

relay, and is disconnected from the primary pin during normal system operation.

During an alarm condition it is connected to the primary pin by the alarm relay.

NC Normally closed—This pin is connected to the “normally closed” contact of the

alarm relay, and is connected to the primary pin during normal system operation.

During an alarm condition it is disconnected from the primary pin by the alarm relay.

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.

Figure 4-10 Alarm Terminal Block

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.

Figure 4-11 Connecting the Alarm Terminal Block to the Alarm Port

Step 6 Reinstall network cables, and turn ON power to the router.
