See the “Grounding the Access Point” section on page 2-46 for grounding instructions.
Grounding the Access Point
The access point must be grounded prior to connecting power.
Warning This equipment must be externally grounded using a customer-supplied ground wire before power is
applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain
that suitable grounding is available. Statement 366
Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074
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).
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 2-14).
Step 4 Connect the grounding lug to the access point grounding screw holes (see Figure 2-14) 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 2-32), or a grounded cable on a cable strand.
Connecting a Fiber-Optic Cable to the Access Point
The fiber-optic kit (GLC-FE-100BX-URGD=) enables the access point to support fiber-optic network
connections. The kit contains these parts:
• 100BASE-BX10-U rugged SFP module
– Single strand fiber bidirectional optical transceiver
– 1.3/1.5 micro-meter wavelength division multiplexing (WDM) function
– 125-Mb/s data rates
