The cable connector unit consists of three components—the outer connector enclosure, the
connector screw, and the cable seal. The front end of the outer cable connector enclosure is from
where the interface cable enters the router, and the rear end with screw thread connects directly to
the chassis cable port on the router. The connector screw houses the rubber cable seal, and the
screw fits tightly in the cable connector enclosure. The cable seal is a small cylindrical rubber

connector screw and prevents water and dust particles from entering the router.
NOTE: The cable seal with single groove must be used for the SFP cables, and that with
three grooves must be used for the RJ-45 cables.
