WARNING
Improper handling could possibly damage cards
Store and transport circuit cards in electrostatic
discharge (ESD) protective containers to prevent
electrical and mechanical damage.
When handling circuit cards not in ESD protective
containers, stand on a conductive floor mat and wear a
wrist strap, connected through a 1-megohm resistor, to
a suitably-grounded object such as a metal workbench
or a DMS frame. (Refer to Nortel [Northern Telecom]
Corporate Standard 5028.)
WARNING
Equipment damage
Take these precautions when removing or inserting a
card:
Do not apply direct pressure to the components.
Do not force the cards into the slots.
WARNING
Hot materials
Exercise care when handling the line card. The line
feed resistor may be very hot.
Caution
Special tools required
Card shrouds and removal tools are required for
removing cards from the line drawers. For
descriptions of these tools, refer to the notes at the end
of this procedure.
Locate the line drawer containing the line card to be removed.
