Figure 43: Removing an M40e MCS

The router has two PCGs installed in the slots labeled
chassis, as shown in "M40e Chassis Description" on page 8. Each PCG weighs
approximately 1 lb (0.5 kg).
To remove the PCGs (see Figure 44 on page 89):
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.
Loosen the thumbscrew at the lower right corner of the PCG faceplate, using a Phillips
3.
screwdriver if necessary.
Grasp the thumbscrew and slide the PCG about halfway out of the chassis.
4.
CAUTION: Be careful to slide the PCG straight out of the chassis to avoid
bending any of the pins on the underside of the board.
Place one hand under the PCG to support it, slide it completely out of the chassis, and
5.
place it on the antistatic mat or in the electrostatic bag.
Repeat the procedure to remove the second PCG.
