Tip

The screw slots in the brackets are spaced to line up with every second pair of screw holes in the rack. When

the correct screw holes are used, the small, threaded holes in the brackets line up with unused screw holes in

the rack. If the small holes do not line up with the rack holes, you must raise or lower the brackets to the next

rack hole.

After you install the voice gateway, you must connect the chassis to a reliable earth ground. For the chassis

ground connection procedures, see the Chassis Grounding section.

Warning

To reduce the risk of electric shock, the chassis of this equipment needs to be connected to permanent earth

ground during normal use. Statement 445

Use a size 14 AWG (2 mm2) or larger copper wire and an appropriate user-supplied ring terminal with an

inner diameter of 1/4 in. (5–7 mm).

To install the ground connection for your router, perform the following steps:

Step 1

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

Step 2

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

Step 3

Attach the ground lug or ring terminal to the chassis as shown in the following image. Use one of the screws provided.

Tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).
