Jackscrew Installation Instructions
(for EIP Ports)
For Cisco Part Number 51-0385-01
Customer Order Number: DOC-781127=
This document provides instructions for replacing the slide-type Ethernet connector
locks with jackscrew type connector locks. Typically, Ethernet ports and cable
connectors have either slide-type or screw-type locks, both of which provide strain
relief and secure the cable to the router port. The slide-type lock is most common, and
it is standard on EIP ports.
If your Ethernet cables use thumbscrews rather than posts, you must replace the
slide-type lock with jackscrews before you can connect the cables to the ports.
You can complete this replacement while the EIP is installed and operating in the
chassis; however, we recommend that you shut down an enabled interfaces before you
work on the port.
