6.
Place one hand around the front of the AS MLC (the modular card housing) and the
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.
7.
If necessary, remove each installed AS MSC and AS MXC from the AS MLC.
8.
After you remove each modular card, immediately place it on an antistatic mat or in
an electrostatic bag.
9.
If you are not reinstalling an AS MLC into the emptied slots within a short time, install
a blank AS MLC panel over each slot to maintain proper airflow in the card cage.
CAUTION:
After removing an AS MLC from the chassis, wait at least 30
seconds before reinserting it or inserting an AS MLC into a different slot.
