Electrostatic discharge can damage integrated circuits or semiconductors
in this module if you touch backplane connector pins. It can also damage
the module when you set configuration plugs or switches inside the
module. Avoid electrostatic discharge by observing the following
precautions:
Touch a grounded object to discharge yourself before handling the
module.
Do not touch the backplane connector or connector pins.
When you configure and replace internal components, do not touch
other circuit components inside the module. If available, use a
static-safe workstation.
When not in use, keep the module in its static-shield bag.
