Juniper MX10008, Hardware Manual

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing a cable. The safety cap keeps the port clean and prevents accidental
exposure to laser light.
CAUTION: Avoid bending a fiber-optic cable beyond its minimum bend radius. An
arc smaller than a few inches in diameter can damage the cable and cause problems
that are difficult to diagnose.
5. Arrange the disconnected cables in the cable manager to prevent the cables from developing stress
points.
6. Simultaneously turn both the ejector handles of the MPC counterclockwise to unseat the MPC.
7. Grasp the handles, and holding the MPC straight, slide it halfway out of the card cage.
CAUTION: The MPC and the handles may be hot. Allow a few minutes for the MPC
and handles to cool by pulling out the MPC halfway out of the chassis. Wear proper
protective, heat-resistant gloves while removing an MPC.
8. Grasp both sides of the MPC at the midpoint, and remove the MPC from the chassis. Slide the MPC
completely out of the chassis, and place the MPC on the antistatic mat or in the electrostatic bag.
CAUTION: The weight of the MPC is concentrated in the back end. Be prepared to
accept the full weight of the MPC—up to 31.57 lb. (14.32 kg)—as you slide the MPC
out of the chassis.
When the MPC is out of the chassis, do not hold it by the ejector handles, bus bars,
or edge connectors. They cannot support the weight of the MPC.
Do not stack MPCs on top of one another after removal. Place each MPC individually
in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
9. If you are not installing another MPC into the empty card slot within a short time, install an MPC cover
over the slot to maintain proper airflow in the card cage.
