ESD Safety Information
Electrostatic discharge (ESD) can damage components of the module. ESD, which
occurs when the 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,
I
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.
I
When you handle the module, follow these precautions:
Always handle the module by the front panel only.
I
Do not touch the components, pins, leads, or solder connections.
I
Before you push the module into the chassis, make sure that the module
I
ejector handles are open.
Do not twist or otherwise force the module into the chassis when you insert it.
I
Use the upper and lower module guides to slowly and carefully slide the
module into the chassis.
Keep the module in its antistatic bag until you are ready to install it.
I
Before you install a module, make the following preparations:
Verify that the chassis is properly installed in a rack, on a table, or on a shelf,
I
according to the instructions in Chapter 4.
Have a flat-blade torque screwdriver available to secure the module to the
I
chassis after you install it.
