Removing an SFM in an M40e Router

To remove an SFM (see Figure 1):

1. Remove the rear component cover by loosening the thumbscrew at each corner of the cover and pulling it straight off the chassis. For complete instructions, see Reinstalling the M40e Components into the Chassis.
2. Place an electrostatic bag or antistatic mat on a flat, stable surface.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
4. If you are removing the active SFM or CFEB-E, press and hold the online/offline button on the faceplate until the yellow LED labeled FAIL lights, which takes about 5 seconds.

   (The effect of removing the active SFM or CFEB-E depends on whether a second SFM or CFEB-E is installed.

5. Loosen the thumbscrew on each ejector locking tab (shown in M40e SFM LEDs), using a Phillips screwdriver if necessary.
6. Pull the end of each ejector handle outward until it is nearly perpendicular to the SFM or CFEB-E faceplate.
7. Grasp the ejector handles and pull firmly to slide the SFM or CFEB-E about halfway out of the chassis.
8. Place one hand under the SFM or CFEB-E to support it, slide it completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

   Caution: When an SFM or CFEB-E is out of the chassis, do not hold it by the ejector handles. They cannot support its weight. Do not stack SFMs or CFEB-Es on top of or under other components. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
