Installing a PIC in an M40e Router

To install a PIC (see Figure 110 on page 202 and Figure 111 on page 203):
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
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.
If the PIC uses fiber-optic cable, verify that there is a rubber safety cap over each
2.
transceiver on the faceplate. Install a cap if necessary.
Align the notches in the connector at the rear of the PIC with the notches in the PIC
3.
slot in the FPC and then slide the PIC in until it lodges firmly in the FPC.
CAUTION: Slide the PIC straight into the slot to avoid damaging the
components on the bottom of the PIC.
Tighten the thumbscrews at the top and bottom of the PIC faceplate simultaneously
4.
and at about the same rate (tightening the two screws alternately or at very different
rates can cause the PIC to become lodged in the FPC slot, making it difficult to turn
the screws). Verify that the PIC is seated properly.
If the PIC uses fiber-optic cable, remove the rubber safety cap from each transceiver
5.
and the end of each cable.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
Insert the appropriate cables into the cable connectors on the PIC.
6.
Arrange each cable in the cable management system to prevent the cable from
7.
dislodging or developing stress points. Secure the cable so that it is not supporting its
own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled
loop in the cable management system. Placing fasteners on the loop helps to maintain
its shape.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do
not allow fastened loops of cable to dangle, which stresses the cable at
the fastening point.
