34 Ethernet Interface Processor (EIP) Installation and Configuration
Replacing Connector Locks
Step 14 To verify that the EIP is using the correct microcode, issue the show configuration or show
controller cxbus command. The show controller cxbus display indicates the currently
loaded and running microcode version for each interface processor.
Router# show configuration
This completes the procedure for downloading microcode to Flash memory.
Replacing Connector Locks
Ethernet connectors have either slide-type or jackscrew-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 the EIP ports. If your Ethernet cables use thumbscrews instead of posts, you must replace the
slide-type lock with jackscrews before you can connect the cables to the ports.
List of Required Parts
You need the following tools and parts to complete this replacement procedure. Because the holes
in the EIP are threaded, you need only two lock washers and two jackscrews for each port. You do
not need to install flat washers and hex nuts on the inside of the interface processor faceplate to
secure the jackscrews. Discard the flat washers and hex nuts that are included in the kit.
• 1/8-inch screwdriver
• Each jackscrew replacement kit includes the following parts:
— Two jackscrews
— Two lockwashers
— Four flat washers (discard)
— Two hex nuts (discard)
Shutting Down Interfaces
If you are replacing the connector locks on an EIP that you have not yet installed in the chassis, skip
this section. If the EIP is already installed in the interface processor slot and the Ethernet interfaces
have been configured, you can avoid potential problems by administratively shutting down the
interfaces and, when the replacement is complete, enabling the interface again. The following steps
provide the commands for shutting down and enabling the interfaces.
The shutdown interface subcommand disables all functions and prevents all packet transmission on
the interface that you specify with the interface type slot/port command. The no shutdown interface
subcommand turns the interface back on. Because interface is a privileged-level configuration
command, you might need a password to enable the privileged level of the EXEC command
interpreter.
Follow these steps to shut down the Ethernet interfaces on the EIP:
Step 1 Follow the steps in the section “Using the EXEC Command Interpreter” on page 25 to
obtain access to the privileged mode of the EXEC.
Step 2 To display the current state of an Ethernet interface, enter the following command:
Router# show interface ethernet slot/port
The status of the interface is displayed. Repeat step 2 for each Ethernet interface and note
the interfaces that need to be shut down.
