Reinstalling the SFMs

The router can have an SFM in each of the slots labeled SFM 0 through

SFM 3 at the rear of the chassis, as shown in Figure 3. To reinstall an

SFM, follow this procedure (see Figure 54):

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. Make sure the router is attached to a proper earth ground. For more information about ESD, see “Preventing Electrostatic Discharge Damage” on page 226.

2.Verify that the ends of the ejector handles are pulled outward to a position nearly perpendicular to the faceplate of the SFM.

3.Place one hand under the SFM to support it and grasp one of the ejector handles at the front with the other hand.

4.Align the rear of the SFM with the guides inside the chassis and slide it in completely.

5.Press the ejector handle at each end of the SFM inward.

6.Tighten the thumbscrew on each ejector locking tab (shown in Figure 8) to seat the SFM firmly in the chassis.
