Cisco Systems 1552H Manual De Usuario

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:

If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug.

Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied 
grounding lug (Panduit PLCD6-10A-L).

The grounding lug and hardware used must comply with local and national electrical codes.

Open the electrical joint compound (supplied), and apply a liberal amount over the metal surface where 
the ground strap screw holes are located (see 

). 

Connect the grounding lug to the access point grounding screw holes (see 

) 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). 

If necessary, strip the other end of the ground wire, and connect it to a reliable earth ground such as a 
grounding rod (see 

), an appropriate grounding point on a metal streetlight pole that is 

grounded (see 

), or a grounded cable on a cable strand.

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)

Fiber backhaul is only possible on the 1552E and 1552EU access points.

Class 1 laser product. Statement 1008

You need a customer-supplied outdoor-rated fiber-optic cable with an LC connector. The cable diameter 
must be 0.20 to 0.35 in. (0.52 to 0.89 cm) in diameter.

To connect a fiber-optic cable to the access point, follow these steps:
