Connect Fiber Cables to the PA-400R Series Firewall

Insert your transceiver into the SFP port you are connecting the cable to.
The grommet used will differ based on whether you install a copper or fiber transceiver.
Unpack the fiber cable gland and separate it into three components — the connector, seal, and end cap.
Thread the fiber cable through the end cap. Unlatch the seal and fit the cable into it, then close the seal latch. Thread the fiber cable through the connector so that the three components are in the order pictured.
Connect the fiber cable to the installed transceiver. Move the three cable gland components towards the firewall. Push the seal into the connector.
Push the connector up to the the SFP port and turn the connector clockwise until there is a click. Make sure that the connector is securely locked in place.
Screw the end cap into the seal and tighten it until the end cap is securely fastened.
Repeat Steps 1 through 6 on the other SFP port if you are connecting a second fiber cable.
