Handling Precautions

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.
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.
For details, see "Installation Prerequisites" and "Installing the Module"
later in this guide.
