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.

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.

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.
