Product Overview
The type of connector lock you use on the EIP ports depends on the type of Ethernet
interface cables you use. Cables with two short posts on the cable connector need a port
with a slide-type lock—a bracket on the port slides (or snaps) around the posts on the
cable connector to secure it. Cables with knurled thumbscrews (screws you can tighten
with your fingers) on the cable connector need a port with jackscrews (into which you
insert and tighten the thumbscrews). Both types of locks are shown in Figure 1.
