To remove the FPCs (see Figure 49 on page 94):
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
2.
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” on page 232.
3.
Locate the FPC or blank panel located in the leftmost slot of the card cage on the
front of the chassis. It is directly below the offline button on the craft interface that is
labeled
FPC0
.
4.
If the slot is covered by a blank panel, you can leave it in place. If the slot contains an
FPC:
a.
Loosen the thumbscrew at each end of the FPC, using a Phillips screwdriver if
necessary.
b.
Pull the ends of the ejector levers, which are adjacent to the thumbscrews, away
from the face of the FPC until they are nearly perpendicular to it.
c.
Grasp the top and bottom flanges of the card carrier and slide the FPC about
halfway out of the card cage.
d.
Place one hand around the front of the FPC (the PIC housing) and the other hand
under it to support it. Slide the FPC completely out of the chassis, and place it on
the antistatic mat or in the electrostatic bag.
CAUTION:
The weight of the FPC is concentrated in the back end. Be
prepared to accept the full weight—up to 15 lb (6.8 kg)—as you slide
the FPC out of the chassis.
When the FPC is out of the chassis, do not hold it by the ejector levers,
bus bars, or edge connectors. They cannot support its weight.
Do not stack FPCs on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a
flat, stable surface.
5.
Repeat Step 4 for each FPC card carrier or blank cover, proceeding from left to right.
