Ethernet Interface Processor (EIP) Installation and Configuration 23
Installation
When a new EIP is inserted or when an EIP is moved to a new slot, the system recognizes the new
Ethernet interfaces but leaves them in a down state until you configure them and change their state
to up with the configure command. The following example display shows the events logged by the
system as a new EIP is inserted in slot 3:
Router#
%OIR-6-INSCARD: Card inserted in slot 3, interfaces administratively shut down
%LINK-5-CHANGED: Interface Ethernet3/0, changed state to administratively down
%LINK-5-CHANGED: Interface Ethernet3/1, changed state to administratively down
%LINK-5-CHANGED: Interface Ethernet3/2, changed state to administratively down
%LINK-5-CHANGED: Interface Ethernet3/3, changed state to administratively down
Verify that the EIP is installed correctly as follows:
Step 1 While the system reinitializes each interface, observe the console display messages and
verify that the system discovers the EIP as follows:
• If you installed a new EIP, the system should recognize all new Ethernet interfaces but
leave them configured as down.
• If you replaced an EIP, the system should recognize each interface and place it in the
same state (up or down) each was in when you removed the EIP.
Step 2 When the reinitialization is complete, verify that the enabled LED on the EIP goes on and
remains on. If it does, proceed to step 5. If it does not, proceed to the next step.
Step 3 If the enabled LED on the EIP fails to go on, suspect that the EIP board connector is not
fully seated in the backplane. Loosen the captive installation screws, then firmly push both
ejectors into place until they are approximately in the same orientation as the EIP faceplate.
Tighten the captive installation screws. After the system reinitializes the interfaces, the
enabled LED on the EIP should go on. If it does, proceed to step 5. If it does not, proceed
to the next step.
Step 4 If the enabled LED still fails to go on, remove the EIP and try installing it in another
available interface processor slot.
• If the enabled LED goes on when the EIP is installed in the new slot, suspect a failed
backplane port in the original interface processor slot.
• If the enabled LED still fails to go on, but other LEDs on the EIP go on to indicate
activity, proceed to step 5 to resume the installation checkout and suspect that the
enabled LED on the EIP has failed.
• If no LEDs on the EIP go on, suspect that the EIP is faulty.
• If the enabled LED still does not go on, do not proceed with the installation. Contact a
customer service representative to report the problem and obtain further instructions.
Instructions for obtaining technical assistance are provided at the end of this
publication.
Step 5 If the EIP is new and not a replacement, proceed to the section “Configuring the Interfaces”
on page 24 to configure the new interfaces. (This does not have to be done immediately, but
new interfaces will not be available until you configure them.)
Step 6 If this installation was a replacement EIP, use the show interfaces or show controllers
cxbus command to verify the status of the interfaces. (Refer to the section “Command
Descriptions and Examples” on page 29.) If you replaced an EIP with a new EIP with a
greater number of ports (for example, if you replaced a four-port EIP with a six-port EIP),
the system will recognize the first four interfaces but will not recognize the two new
additional interfaces. The two new interfaces will remain in the down state until you
configure them.
