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.

  • Page 2: Obtaining Technical Assistance

    Obtaining Technical Assistance This document contains instructions for replacing the slide-type connector locks that are standard on Cisco 7000 EIP ports with jackscrews so that you can connect cables with thumbscrews to the ports. If you encounter problems that you are unable to resolve, contact a customer service representative or the Technical Assistance Center (TAC) for assistance.
  • Page 3 Figure 1 The EIP is the 2, 4, or 6-port high-speed Ethernet interface processor for the Cisco 7000 router. The EIP and other interface processors (IPs) slide into slots in the rear of the router chassis (which is shown in Figure 2) and connect directly to the backplane. You can replace the connector locks while the EIP is installed in the chassis, provided that you first shut down the interface ports on which you will change connector locks.

    Note: Cisco Systems recommends that you do so as a precaution to protect the electronic components in the system and to avoid creating problems on your network. Shutting Down Interfaces It is unlikely that interface ports will be enabled if you have not been able to connect the network interface cables.
