Installing a PTX5000 FPC
CAUTION: The FPC power connector is located in the corner where the bottom and
the connector edges meet. If a power connector prong becomes bent, it no longer
aligns with the socket connector on the midplane, and the FPC no longer functions.
To install an FPC (see Figure 281 on page 521 and Figure 282 on page 523 ):
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.
2. Place the FPC on an antistatic mat.
3. Take each PIC to be installed in the replacement FPC out of its electrostatic bag and identify the
slot on the FPC where it will be connected.
4. Verify that each fiber-optic PIC has a rubber safety cap covering the PIC transceiver. If it does not,
cover the transceiver with a safety cap.
5. Install each PIC into the appropriate slot on the FPC. For information about installing a PIC, see the
installation instructions in
"Replacing a PTX5000 PIC" on page 524 .
6. Locate the slot in the FPC card cage in which you plan to install the FPC.
7. Inspect the slot in the FPC card cage to verify that there are no missing or bent pins on the
midplane.
8. Inspect the FPC to verify that the connectors are not misaligned or damaged.
9. Orient the FPC vertically with the component side facing to the right. 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.
10. Carefully align the connector edge of the FPC with the appropriate empty slot in the chassis.
