Juniper PTX5000, Hardware Manual

Page: 572 / 721

CAUTION: The weight of the FPC is concentrated in the back end. Be prepared to
accept the full weight—up to 50 lb (22.7 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 handles, bus bars,
or edge connectors. These components 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.
10. If you are not reinstalling an FPC into the emptied FPC slot within a short time, install a blank FPC
panel over the slot to maintain proper airflow in the FPC card cage.
CAUTION: After removing an FPC from the chassis, wait at least 30 seconds before
reinserting it, installing another FPC in that slot, removing an FPC from a different
slot, or inserting an FPC into a different slot.
To install an 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.
1. Attach an 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 installed.
4. Verify that each fiber-optic transceiver has a rubber safety cap covering the transceiver. If it does
not, cover the transceiver with a safety cap.
5. Install each PIC into the appropriate slot on the FPC. See
PTX Series PIC/FPC Compatibility
for
installing the supported PICs 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.
