Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage can occur when electronic cards or components are improperly
handled. This will cause complete or intermittent failures. We recommend using an ESD-preventive
strap when you handle a router or one of its components. Electromagnetic interference (EMI) shielding
is an integral component of the router.
