Installing an M320 FPC

230
To install an FPC (see Figure 94 on page 232
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.
Place the FPC on an antistatic mat.
2.
Take each PIC to be installed in the replacement FPC out of its electrostatic bag and
3.
identify the slot on the FPC where it will be connected.
Verify that each fiber-optic PIC has a rubber safety cap covering the PIC transceiver.
4.
If it does not, cover the transceiver with a safety cap.
Install each PIC into the appropriate slot on the FPC. For information on installing a
5.
PIC, see "Installing an M320 PIC" on page
Locate the slot in the FPC card cage in which you plan to install the FPC.
6.
Lift the FPC into place and carefully align first the bottom, then the top of the FPC
7.
with the guides inside the card cage. Be sure the FPC is right-side up, with the
components on the right of the FPC.
CAUTION: When the FPC is out of the chassis, do not hold it by the ejector
handles, bus bars, or edge connectors. They cannot support its weight.
Slide the FPC all the way into the card cage until you feel resistance.
8.
Starting with the ejector handles on the FPC faceplate nearly horizontal, simultaneously
9.
turn both ejector handles clockwise to seat the FPC.
If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety
10.
cap from each transceiver and 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.
Insert the appropriate cable into the cable connector ports on each PIC on the FPC.
11.
Secure the cables so that they are not supporting their own weight. Place excess cable
out of the way in a neatly coiled loop, using the cable management system. Placing
fasteners on a 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.
