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 Northern Telecom Corporate
Standard 5028.)
WARNING
Equipment damage
Take these precautions when removing or inserting a
card:
1. Do not apply direct pressure to the components.
2. 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 note at the end
of this procedure.
