Connecting a PA-E3 Cable
On a PA-E3(=) you use only one coaxial cable, and on a PA-2E3(=) you can use one or two coaxial
cables.
Caution
You can attach only an EIA/TIA-612 and EIA/TIA-613 75-ohm coaxial cable to the PA-E3 installed in
your router. Attaching a compact serial cable of another interface type to the port adapter could damage
your router or the hardware at the network end of the cable.
To connect a coaxial cable to a PA-E3, follow these steps:
Step 1
Attach the coaxial cable directly to the receptacle on the PA-E3 and tighten the BNC connectors. (See
Note
Port adapters have a handle attached, but this handle is not shown to allow a full detailed view
of the faceplate.
When attaching the cable receptacle on the PA-E3, use the cable-management bracket that
shipped with your router for extra strain relief.
