Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•
Before beginning any procedures requiring access to the router interior, locate the emergency
power-off switch for the room in which you are working.
power-off switch for the room in which you are working.
•
Disconnect all power and external cables before moving a router.
•
Do not work alone when potentially hazardous conditions exist.
•
Never assume that power has been disconnected from a circuit; always check.
•
Do not perform any action that creates a potential hazard or makes the equipment unsafe.
•
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures.
improperly handled, results in complete or intermittent failures.
Use the following guidelines for preventing ESD damage:
•
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•
Connect the equipment end of the strap to an unfinished chassis surface.
•
When installing a component, use any available ejector levers or captive installation screws to
properly seat the bus connectors in the backplane.

•
When removing a component, use any available ejector levers or captive installation screws to
release the bus connectors from the backplane or midplane.

•
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
connectors.
•
Place a removed board component-side-up on an antistatic surface or in a static shielding container;
otherwise, immediately place it in a static shielding container.
otherwise, immediately place it in a static shielding container.
•
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

•
Never attempt to remove the printed circuit board from the metal carrier.
Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement
should be between 1 and 10 megohms (Mohm).
