Installing the Grounding Lug on Cisco 2600 Series and Cisco 3600 Series Routers


For some types of network connections, a grounding lug must be installed on Cisco 2600 series and Cisco 3600 series routers to ensure proper electrical protection. The grounding lug must be installed before certain network modules areused.


Note Grounding lugs are necessary for Cisco 2600 series and Cisco 3600 series routers using the NM-1V, NM-2V, NM-8AM, NM-16 and NM-16AM network modules.

Required Tools and Equipment


Warning Only trained and qualified personnel should be allowed to install or replace this equipment.


Installation might require some tools and equipment that are not provided as standard equipment with the router. Following are the tools and parts required for a typical router installation:

Flat-blade screwdrivers: small, 3/16-in. (0.476 cm) and medium, 1/4-in. (0.625 cm)

No. 2 Phillips screwdriver

ESD-preventive wrist strap

Tape

Number 6 gauge grounding wire

Pliers to connect grounding wire to connector

The grounding lugs kit consists of:

Cisco 3620 grounding lug bracket

Cisco 3640 grounding lug bracket

Angled grounding lug (for Cisco 2600 series and Cisco 3660 routers)

Straight grounding lug (for Cisco 3620 and Cisco 3640 routers)

2 bracket screws (to attach the bracket to the chassis)

2 grounding lug screws (to attach the grounding lug to the bracket or chassis)

The contents of thegrounding lug kit are shown in Figure 1.

Installing the Grounding Lug on a Cisco 2600 Series Router

This section describes the procedure to connect the grounding lug to a Cisco 2600 series router. Figure 2 shows the typical location for placing the grounding lug on the router.

Figure 2 Cisco 2600 Series Grounding Lug Location

To connect a grounding wire to the grounding lug on a Cisco 2600 series router, complete the following tasks:


Step 1 Place a number 6 gauge grounding wire in the grounding lug connector.

Step 2 Squeeze the grounding lug connector until the grounding wire is firmly in place.

Step 3 Mount the grounding lug to the Cisco 2600 series chassis using the supplied screws as shown in Figure 3.

Figure 3 Cisco 2600 Series Grounding Lug Installation


Installing the Grounding Lug on a Cisco 3620 or Cisco 3640 Router

To attach the grounding lug to your router chassis, complete the following tasks:


Step 1 Turn OFF power to the router. However, to channel ESD voltages to ground, do not unplug the power cable. Remove all network interface cables, including telephone cables, from the rear panel.

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


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.


Step 2 Use a no. 2 Phillips screwdriver to remove either of the following:

1 mounting screw from the power supply on the right side of the Cisco 3620 router rear panel

2 mounting screws from the power supply on the right side of the Cisco 3640 router rear panel

Figure 4 and Figure 5 show Cisco 3620 DC and AC power supplies; Figure 6 and Figure 7 show Cisco 3640 DC and AC power supplies. The DC and AC power supplies for these router models differ in appearance, but the number and position of the mounting screws are the same for each platform.

Figure 4 Cisco 3620 DC Power Supply Mounting Screw

Figure 5 Cisco 3620 AC Power Supply Mounting Screw

Figure 6 Cisco 3640 DC Power Supply Mounting Screws

Figure 7 Cisco 3640 AC Power Supply Mounting Screws

Step 3 Attach the bracket over the power supply using the screw(s) that you removed in Step 2. (See Figure 8 and Figure 9.)

Figure 9 Attaching the Bracket over the Cisco 3640 Power Supply

Step 4 Strip one end of the 6-AWG wire to expose approximately 0.75 in. (20 mm).

Step 5 Crimp the grounding lug around the wire. (See Figure 10.)

Figure 10 Crimping the Lug Around the Wire

Step 6 Use the no. 2 Phillips screwdriver to fasten the grounding lug to the bracket on Cisco 3620 and Cisco 3640 routers. (See Figure 11, Figure 12, and Figure 13.)


Note If your Cisco 3620 router is connected to an redundant power supply (RPS) unit, fasten the grounding lug to its bracket diagonally as shown in Figure 12. This modified installation allows clearance for the RPS cable.

Figure 12 Grounding Lug Fastened to Bracket on Cisco 3620 Power Supply with RPS

Figure 13 Grounding Lug Fastened to Bracket on Cisco 3640 Power Supply

Step 7 Connect the other end of the grounding lug wire to a grounding point at your site.

Step 8 If you have a Cisco 3620 router, apply the "Disconnect All Connections Before Opening the Cover" label to the upper part of the power supply. (See Figure 14.)

If you have a Cisco 3640 router, apply the "Disconnect All Connections Before Opening the Cover" label to the upper part of the power supply, and apply the supplied voltage rating label for your power supply to the lower part of the bracket. (See Figure 15.)

Step 9 Reinstall network cables, and turn ON power to the 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.

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.
