Chapter 3 Installing the Cisco RF Switch
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.
The hex-head screws with locking washers, grounding wire, and heatshrink tubing are not available from
Note
Cisco Systems. You must obtain them from an electrical-connector vendor.
To connect the grounding wire to the Cisco uBR 3x10 RF Switch:
Ensure that the Cisco uBR 3x10 RF Switch is powered off and that you have disconnected the AC power
Step 1
cord or DC power leads from the power supply.
Strip approximately 0.75 in. (2 cm) of shielding from one end of the grounding wire.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding lug and crimp the
Step 3
grounding lug securely to the grounding wire.
Slide the segment of heatshrink tubing over the joint of the grounding lug and grounding wire so that the
Step 4
exposed connection is covered.
Shrink the tubing in place using a suitable heating device.
Step 5
Attach the grounding lug to the power-supply side of the Cisco uBR 3x10 RF Switch chassis using the
Step 6
two M5 hex-head screws.
Connect the other end of the grounding wire to an appropriate ground source.
