Figure 44: Removing a M40e PCG

The router can have a Routing Engine in each of the slots labeled
rear of the chassis, as shown in "M40e Chassis Description" on page 8. Each Routing
Engine weighs approximately 1.5 lb (0.7 kg).
The routing engine is hot-pluggable, as described in "M40e Field-Replaceable Units
(FRUs)" on page 157. For a description of the effect of removing a routing engine, see
"M40e Host Module Description" on page 23.
To remove a Routing Engine (see Figure 45 on page 90):
Place an electrostatic bag or antistatic mat on a flat, stable surface.
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
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" on page 232.
Using your thumbs, push and hold the red tab on each extractor clip toward the outer
3.
edge of the unit. Push the ends of the extractor clips outward to unseat the Routing
Engine from the chassis.
Grasp the extractor clips and slide the unit about halfway out of the chassis.
4.
CAUTION: Slide the Routing Engine straight out of the chassis. Damage
can result if the Routing Engine gets lodged because of uneven movement.
Place one hand under the Routing Engine to support it, slide it completely out of the
5.
chassis, and place it on the antistatic mat or in the electrostatic bag.
If a second Routing Engine is installed, repeat the procedure to remove it.
