7 Installing the Chassis

This section provides the procedures for installing and grounding the router chassis.

Chassis Installation Options

You can set the chassis on a desktop or mount it on a wall.


Tip Before proceeding, consider the location of the equipment with respect to a good ground. See the "Grounding the Chassis" section.


See the following instructions:

Setting the Chassis on a Desktop

Wall-Mounting the Chassis

Grounding the Chassis


Caution Use only the mounting hardware supplied with this product.

Setting the Chassis on a Desktop

You can place Cisco VG202 and Cisco VG204 routers on a desktop or shelf.


Caution Do not place anything on top of the router that weighs more than 5 pounds (2.25 kg), and do not stack routers on a desktop. Excessive distributed weight of more than 5 pounds or pound point load of 5 pounds on top could damage the chassis.

After you install the router, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the "Grounding the Chassis" section.

Wall-Mounting the Chassis

You can mount the router on a wall or other vertical surface by using the molded mounting brackets on the bottom of the router and two number-six, 3/4-inch (M3.5 x 20 mm) screws. You must provide the screws. Figure 5 shows the mounting-screw slots on the router.


Caution If you are mounting the router on drywall, use two hollow-wall anchors (1/8 inch with 5/16-inch drill bit, or M3 with 8-mm drill bit) to secure the screws. If the screws are not properly anchored, the strain of the network cable connections could pull the router from the wall.

Figure 5 Mounting-Screw Slots for Wall-Mounting the Cisco VG202 or Cisco VG204 Router

Rubber feet

2

Mounting-screw slots


The following conditions must be met when you mount the router:

Because you will use the LEDs as status and problem indicators, the LEDs on the front panel must face upward and must be easily visible.

The back panel must face downward to reduce strain on the cable connections.

The power supply must rest on a horizontal surface such as the floor or a table. If the power supply is not supported, it could place strain on the power supply cable and cause it to disconnect from the connector on the router back panel.

To wall-mount the Cisco VG202 or Cisco VG204 voice gateway, follow this procedure:


Step 1 Secure two screws 5 7/16 inches (13.81 centimeters) apart into a wall and 1/8 inch (0.32 centimeter) out from the wall.

Step 2 Hang the voice gateway on the screws as shown in Figure 6.

Step 3 Place the power supply on a horizontal surface.

Grounding the Chassis

You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.

For NEC-compliant grounding, use size AWG 14 (2 mm2) or larger wire and an appropriate user-supplied ring terminal.

For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm2) or larger wire and an appropriate user-supplied ring terminal.

To ground the chassis, you will need a crimp tool and a number 2 Phillips screwdriver.

To connect the chassis to a reliable earth ground, perform the following steps:


Step 1 Locate a suitable ground.


Tip Using a multimeter, measure the resistance between various possible ground locations, such as between the ground of a junction box (outlet) and the ground of a power tap, between the ground of a junction box and a metal water pipe, between the voice gateway chassis and the ground of a power tap, or between the chassis and the ground of a junction box. A good ground connection should read between 0.0 and 0.5 ohm.


Step 2 Strip one end of the ground wire to the length required for the ring terminal.

Step 3 Crimp the ground wire to the ring terminal, using a crimp tool of the appropriate size.

Step 4 Attach the ring terminal to the chassis as shown in Figure 7. For a ring terminal, use one of the screws provided. Use a number 2 Phillips screwdriver, and tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).
