Preparing Network Connections
Some Ethernet transceivers can connect directly to the AUI ports on the EIP and do not
Note
require an AUI or transceiver cable. When planning your connections, consider the size and shape
of any transceivers that will connect to the EIP ports directly, and avoid connecting transceivers that
overlap and impair access to connections on other interface processors.
Typically, Ethernet connectors have either slide-type or jackscrew-type locks. (See Figure 2-16.)
The most common are those which use a slide-type lock, which is the type used on the EIP ports.
The connector on the left in Figure 2-16 shows a slide-type lock. When the cable is connected to the
15-pin port, you snap a metal bracket up over two posts on the cable connector to secure it in the port
and provide strain relief.
The jackscrew-type lock, shown on the right in Figure 2-16, uses two thumbscrews or jackscrews,
which are usually attached to the cable connector instead of the posts and sliding bracket. When the
cable is connected to the 15-pin port, you secure it by screwing the thumbscrews into the jackscrews
adjacent to the connector. The slide-type locks are standard on the EIP ports; however, conversion
kits are included with each EIP to replace the slide-type locks on ports you will connect to interface
equipment that uses the screw-type locks. For specific replacement instructions, refer to the
installation document that accompanies the jackscrew kit.
