ESD Safety Information
Electrostatic discharge (ESD) can damage components of the module.
ESD, which occurs when a module is improperly handled, can cause
complete or intermittent failures.
CAUTION: To prevent ESD-related damage:
■ Always wear an ESD wrist strap (not provided) when you handle a
module, ensuring that the strap makes good skin contact and is
properly grounded.
■ Keep the module in its antistatic bag until you are ready to install it.
Handling Precautions
When you handle a module, follow these precautions:
■ Always handle the module by the front panel only.
■ Do not touch the components, pins, leads, or solder connections.
■ Do not twist or otherwise force the module into the chassis when you
insert it into the module guides.
■ Before you push the module into the chassis, verify that the module
ejector handles are open.
■ When you slide the module into the 7-slot chassis, match the left and
right module guides. In the 8-slot chassis or 16-slot chassis, match the
upper and lower module guides.
