Tools and Equipment

•Grounding lug (included)—The grounding lug must have two M5 screw holes with 0.625 to 0.75 in. (15.86 to 19.05 mm) spacing between them.

•Two M5 (metric) hex-head screws with locking washers.

•8-mm wrench or nut driver (or adjustable wrench)

•Grounding wire (4 AWG recommended)—The length of the grounding wires depends on the location of your router within the site and its proximity to proper grounding facilities.

•One segment of 1.5 in. (3.8 cm) length of 0.5 in. (1.2 cm) diameter heatshrink tubing.

•Heating device for the heatshrink tubing.

Note The hex-head screws with locking washers, grounding wire, and heatshrink tubing are not available from Cisco Systems. You must obtain them from an electrical-connector vendor.

To connect the grounding wire to the Cisco uBR 3x10 RF Switch:

Step 1 Ensure that the Cisco uBR 3x10 RF Switch is powered off and that you have disconnected the AC power cord or DC power leads from the power supply.

Step 2 Strip approximately 0.75 in. (2 cm) of shielding from one end of the grounding wire.

Step 3 Insert the stripped end of the grounding wire into the open end of the grounding lug and crimp the grounding lug securely to the grounding wire.

Step 4 Slide the segment of heatshrink tubing over the joint of the grounding lug and grounding wire so that the exposed connection is covered.

Step 5 Shrink the tubing in place using a suitable heating device.

Step 6 Attach the grounding lug to the power-supply side of the Cisco uBR 3x10 RF Switch chassis using the two M5 hex-head screws.

Step 7 Connect the other end of the grounding wire to an appropriate ground source.
