Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
2.
ESD points on the chassis.
Use one of the following methods to take the AS MLC offline:
3.
Press and hold the AS MLC online/offline button. The green
button begins to blink. Hold the button down until the LED goes out. The
online/offline button for each AS MLC is located directly above it on the craft
interface.
Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see the
NOTE: The slot number corresponds to the lowest numbered slot for
which the AS MLC is installed.
Simultaneously turn both the ejector handles counterclockwise to unseat the AS MLC.
4.
Grasp the handles, and slide the AS MLC straight out of the card cage halfway.
5.
Place one hand around the front of the AS MLC (the modular card housing) and the
6.
other hand under it to support it. Slide the AS MLC completely out of the chassis, and
place it on the antistatic mat or in the electrostatic bag.
CAUTION: The weight of the AS MLC is concentrated in the back end. Be
prepared to accept the full weight—up to 15.27 lb (6.93 kg)—as you slide
the AS MLC out of the chassis.
When the AS MLC is out of the chassis, do not hold it by the ejector handles,
bus bars, or edge connectors. They cannot support its weight.
Do not stack AS MLCs 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.
If necessary, remove each installed AS MSC and AS MXC from the AS MLC.
