428 ! Verifying CFEB Failure

Step 5: Perform a Swap Test on the CFEB

To perform a swap test on an CFEB, follow the procedure in the M10i Internet Router

Hardware Guide for replacing and installing a CFEB.

One or two CFEBs can install into the uppermost slots in the rear of the chassis.

Only one CFEB is active at a time, with the optional second CFEB in reset mode.

CFEBs are hot-pluggable. Removing the standby CFEB has no effect on router

function.

If the active CFEB fails or is removed from the chassis, the effect depends on

whether two CFEBs are installed:

! If there is only one CFEB, forwarding halts until the CFEB is replaced and

functioning again.

! If there are two CFEBs, forwarding halts until the standby CFEB boots and

becomes active.

In both cases, all components in the Packet Forwarding Engine reset, and it takes

approximately one minute for the new CFEB to become active; synchronizing

router configuration information can take additional time, depending on the

complexity of the configuration.

Action To perform a swap test on a CFEB, follow these steps:

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and

connect the strap to one of the ESD points on the chassis.

3. If you are removing the active CFEB, press and hold the offline button on the

faceplate until the amber LED labeled FAIL lights, which takes about 5 seconds.

(The effect of removing the active CFEB depends on whether a second CFEB is

installed.

4. Loosen the thumbscrew on each ejector lever using a Phillips screwdriver if

necessary.

5. Pull the end of each ejector lever outward until it is nearly perpendicular to the

CFEB faceplate.

6. Grasp the ejector levers and pull firmly to slide the CFEB about halfway out of

the chassis.

CAUTION: Before performing a swap test, always check for bent pins in the

midplane and check the CFEB for stuck pins in the connector. Pins stuck in the

component connector can damage other good slots during a swap test.
