Card damage—transport

Take the following precautions to protect circuit cards from

electrical and mechanical damage during transport:

When handling a circuit card not in an electrostatic discharge

(ESD) protective container, stand on a conductive ﬂoor mat

and wear a wriststrap connected, through a 1-megohm

resistor, to a suitably grounded object, such as a metal

workbench or a DMS switch frame (Northern Telecom

[Nortel] Corporate Standard 5028). Store and transport

circuit cards in an ESD protective container.

Static electricity damage

Before removing any cards, put on a wriststrap and connect it

to the wriststrap grounding point on the left side of the

modular supervisory panel (MSP) of the LCME. This

protects the equipment against damage caused by static

electricity.

Equipment damage

Take the following precautions when removing or inserting a

1. Do not apply direct pressure to the components.

2. Do not force the cards into the slots.

Hot materials

Exercise care when handling the line card. The line feed

resistor may be very hot.
