Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly
handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral
component of the line card. Cisco recommends using an ESD-preventive strap whenever you are handling
network equipment or one of its components.
The following are guidelines for preventing ESD damage:
• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect
• Handle SIPs by the captive installation screws, the provided handle, ejector levers, or the line card metal
• Place removed SIPs board-side-up on an antistatic surface or in a static shielding bag. If you plan to
• Avoid contact between the SIPs and clothing. The wrist strap only protects the board from ESD voltages
Caution
For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1
and 10 megohms.
Required Tools and Equipment
You need the following tools and parts to remove and install SIPs:
• Flat-blade or Phillips screwdriver
the equipment end of the connection cord to an ESD connection socket on the router or to bare metal on
the chassis.
carrier only; avoid touching the board or connector pins.
return the component to the factory, immediately place it in a static shielding bag.
on the body; ESD voltages on clothing can still cause damage.
