Replacing Host Module Components
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.
Verify that the extractor clip at each end of the Routing Engine is flipped
toward the outer edge of the unit. If necessary, use your thumbs to push and
hold the red tab on each extractor clip toward the outer edge, then push the
ends of the extractor clips outward.
Place one hand under the Routing Engine to support it and grasp one of the
extractor clips on the faceplate with the other hand.
Align the rear of the Routing Engine with the guide rails inside the chassis
and slide it in completely.
Press the extractor clip at each end of the Routing Engine inward to seat the
unit firmly in the chassis.
Check the host module LEDs on the craft interface to verify that the green
LED labeled is lit for the host module to which the Routing Engine

belongs (Figure 11 shows the LEDs).
You can also verify correct Routing Engine functioning by issuing the
