Connecting a Fiber-optic Cable to the AP
Step 4
Connect the grounding lug to the access point grounding screw holes using the supplied two Phillips
head screws (M4 x10 mm) with lock washers. Tighten the grounding screw to
22 to 24 lb-in (2.49 to 2.71 Nm).
Step 5 Connect the other end of the ground wire to a reliable earth ground, such as a grounding rod or an
appropriate grounding point on a metal streetlight pole that is grounded.
Connecting a Fiber-optic Cable to the AP
The Cisco supplied fiber-optic kit enables the access point to support fiber-optic network connections.
Your require the following materials for connecting the fiber-optic cable to the AP:
• Small form-factor pluggable (SFP) transceiver module
•
SFP module adapter
• SC or Duplex LC fiber-optic cables. The outer diameter of the fiber optic cable should be 0.24-0.47
inches (6-12 mm).
•
Cable gland. The cable gland cannot hold a cable with diameter more than 0.47” (12 mm).
• Adjustable wrench
You can connect the fiber-optic networking cable to the SFP port (labeled '4' on the base of the AP). The
small form-factor pluggable (SFP) transceiver module is used to connect the cable to the SFP port. The
SFP port provides both Power-over-Cable and backhaul over fiber options. To install the SFP transceiver
module and the cable, follow this procedure:
Step 1
Ensure that all power sources have been disconnected from the access point.
Step 2 Remove the covering plug from the SFP port.
Step 3
Insert the SFP module into the SFP port, and ensure that it latches properly.
Step 4 Loosen the cable gland’s nut (round end of the cable gland) by turning counterclockwise, but do not
remove.
Step 5
Thread the fiber optic cable, from its unterminated end, into the cable gland. See Figure 4-8 and
Figure 4-9 .
Thread the cable through the gland all the way till the gland is near the SC or LC optic fiber connectors.
The cable gland’s nut must remain loose at this time.
Note The SC or LC optic fiber connectors are too big to pass through the cable gland. That is the reason why
you need to thread the cable through the gland from the unterminated end (even if the cable is quite long).
Step 6
Insert the SC or LC optic fiber connector-end of the cable, into the SFP module adapter. Do not attach
the cable gland to the adapter yet. See
Figure 4-10 .
Step 7 Insert the SC or LC optic fiber connector into the SFP module and ensure that it latches into place. See
Figure 4-10 .
Step 8
Add sealant or tape around the adapter's pipe thread, and then it screw into the AP chassis.
