Chapter 2 Installing the Access Point
Connecting a Fiber-Optic Cable to the Access Point
Note When the access point is cable strand mounted, the strand support cable and the mounting hardware
provide grounding for the access point.
In all outdoor installations and when powering the access point with AC power, you must follow these
instructions to properly ground the case:
Step 1 If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug.
Step 2 Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied
grounding lug (Panduit PLCD6-10A-L).
Note The grounding lug and hardware used must comply with local and national electrical codes.
Step 3 Open the electrical joint compound (supplied), and apply a liberal amount over the metal surface where
the ground strap screw holes are located (see Figure 2-13).
Step 4 Connect the grounding lug to the access point grounding screw holes (see Figure 2-13) using the
supplied two Phillips head screws (M4 x10 mm) with lock washers. Tighten the grounding screw to
22 to 24 in. lbs (2.49 to 2.71 Nm).
Step 5 If necessary, strip the other end of the ground wire, and connect it to a reliable earth ground such as a
grounding rod (see Figure 2-2), an appropriate grounding point on a metal streetlight pole that is
grounded (see Figure 2-38), or a grounded cable on a cable strand.
Connecting a Fiber-Optic Cable to the Access Point
The fiber-optic kit (AIR-1520-FIB-REEL=) enables the access point to support fiber-optic network
connections. The kit contains these parts:
• Eight screws
• Two small take-up reels
• Two large take-up reels
• One liquid-tight adapter—Accepts a cable diameter of 0.20 to 0.35 inches (0.51 to 0.89 cm)
Note Fiber backhaul is only possible on the 1552E and 1552EU access points.
