Installing the Cisco Coaxial Media Converter
Revised: April 24, 2014, 78-21661-01
Before installing the Cisco Coaxial Media Converter (CMC), review the safety precautions in the
Cisco Remote-PHY Solution Installation and Configuration Guide.
For more information see:

Step 1 Install F-Connector on the Cisco CMC:
a. Unscrew the six ½-inch closure bolts on Cisco CMC lid using a torque wrench and open the lid.
b. Cisco CMC supports PG11 and 5/8” F-connectors. Trim the F-connector with a heavy-duty wire cutters to match the
F-connector strip on the Cisco CMC. To use PG11 F-connector, remove the PG11 to 5/8” adapter from the port with a
torque wrench.

c. Lightly loosen the seizure screw. Do not remove it. Install the F-connector into the RF port and tighten the connector
nut with a torque wrench and then tighten the seizure screw using a slot screwdriver.

d. Install a 5/8” port plug into each unused RF port.
e. Close the lid and lightly tighten the six ½-inch closure bolts.
Step 2 Mount the Cisco CMC either on a wall or strand. The maximum weight of the Cisco CMC is 11.8 kg (26 lb).
• Wall-Mounting
158.4mm
Mounting Holes
291mm
a. Drill four holes in the wall at a distance of 291 mm x 158.4 mm. Align the Cisco CMC horizontally with the holes on
the wall and ensure proper ventilation around it.
b. Insert an M8 or 5/16” expansion bolt into each hole.

• Strand-Mounting
a. The minimum diameter of the strand should be 5/16”. Loosen the strand clamp bolts to separate the clamps enough to
insert the strand. Position the Cisco CMC on the strand and lightly tighten the strand clamp bolts with your finger.
b. Move the Cisco CMC on the strand as required for installing the cables and tighten the strand clamp bolts using a torque
wrench and ½-inch socket from 5 ft-lb to 8 ft-lb.
Step 3 Open the Cisco CMC lid to perform one or all of the following:
a. To connect the RJ-45 cable, remove the RJ-45 PG16 port plug. Insert the RJ-45 cable through the PG16 gland and the
RJ-45 port. Then, plug in the RJ-45 connector into the GE port. Tighten the PG16 gland into the RJ-45 port using a
torque wrench (4.44 ft-lb) and then tighten the dome cap using a torque wrench (2.44 ft-lb).
b. To connect the optical fiber to the SFP module, remove the 5/8” port plug. Insert the SFP module into the SFP cage, if
not already installed. Insert the optical fiber into the fiber port and then insert the connector into the SFP module port.
Secure the optical fiber using the cable clips as shown in the figure. Seal the fiber port after the installation. Supported
SFPs include EPON SFP, GPON SFP, and GE SFP.

c. To connect the optical fiber to the FRx module, remove the 5/8” port plug. Insert the optical fiber into the fiber port and
connect it to the SC-SC adapter as shown in the figure. Secure the optical fiber using the cable clips. Seal the fiber port
after the installation.

Step 4 Connect the coaxial cables as required.
Step 5 Attach one end of an 18-gauge or larger wire to the grounding screw on the Cisco CMC using the M4 panhead Phillips
screw. Then, attach the other end of the grounding wire to an appropriate ground source.
Step 6 For 220V, connect the AC power cord to an AC power source. For 60V, connect the coaxial cable to the CATV IN or
one of the RF output ports. Then, insert an AC shunt for the coaxial cable. Power on the Cisco CMC. It may take up
to three minutes for the Cisco CMC to come Online.
Step 7 Verify if the PWR and STATUS LEDs are green, UPLINK LED is green or blinking green, and ALARM LED is OFF, to
ensure that the Cisco CMC is operational.
Step 8 Close the lid and tighten the six ½-inch closure bolts from 5 ft-lb to 12 ft-lb in the correct sequence as shown in the
figure below using a torque wrench.
