Installing an M120 FEB

To install a FEB (see Figure 1):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Place one hand underneath the FEB to support it. With the other hand, hold one of the ejector handles on the FEB faceplate.
3. Carefully align the sides of the FEB with the guides inside the chassis.
4. Carefully slide the FEB into the chassis, ensuring that it is correctly aligned.
5. Grasp both ejector handles and press them inward to seat the FEB.
6. Tighten the captive screws on the ejector handles.
7. Press the offline/online button until the green OK LED blinks to bring the FEB online.
8. To verify that the FEB is functioning normally, check the LEDs on its faceplate. The green OK LED should light steadily a few minutes after the FEB is installed. If the FAIL LED is lit steadily, remove and install the FEB again (see Removing an M120 FEB). If the FAIL LED still lights steadily, the FEB is not functioning properly. Contact your customer support representative.

   To check the status of the FEBs, issue the following CLI command:
