Figure 53: Reinstalling the M40e Front Impeller Assembly
Reinstalling the FPCs
The FPCs install into the card cage at the front of the chassis, as shown in “M40e Chassis
Description” on page 8.
NOTE:
To help you work systematically, reinstall FPCs starting at the left
side of the card cage and working toward the right. You can install FPCs in
any order, however.
Be sure there is a blank panel over every empty slot. The blank panels must
be in place during router operation to guarantee adequate circulation of
cooling air.
To reinstall the FPCs (see Figure 54 on page 100):
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. For more information about ESD,
see “Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series
Router” on page 232.
2.
Locate the leftmost slot in the FPC card cage on the front of the chassis. It is directly
below the offline button on the craft interface that is labeled
FPC0
. Locate the FPC
that you labeled
FPC0
during removal.
3.
Verify that the ends of the ejector levers, which are located at each end of the FPC,
are pushed outward, nearly perpendicular to the face of the FPC.
4.
Grasp the front of the FPC with one hand and place the other hand under the FPC to
support it.
CAUTION:
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.
5.
Align the rear bottom corners of the FPC with the guides at the bottom of the FPC
slot. Slide the FPC into the card cage until it contacts the midplane.
