PROPER HANDLING AND GROUNDING
PRECAUTIONS REQUIRED
XDM-300 equipment contains components sensitive to
electrostatic discharge (ESD). To prevent ESD damage,
strictly observe all the precautions listed in Protection against
ESD (on page
). Keep parts and cards in their antistatic
packaging material until you are ready to install them.
Use an antistatic wrist strap connected to a grounded
equipment frame or rack when handling cards and modules
during installation, removal, or connection to internal
connectors.
Before you start:
When inserting cards and modules, make sure to carefully align the card or
module with the shelf guide rails. If you feel resistance during insertion,
immediately retract the card/module and then repeat the process.
Hold the card/module straight during insertion and removal, and pull or push it
slowly and carefully to avoid touching components located on adjacent
cards/modules.
Do not use excessive torque when tightening the fastening screws of cards and
modules.
Visually inspect the card and the mating backplane connectors and make sure
that there are no signs of physical damage. In particular, check for bent
connector pins.
