Using Redundant Power

If your system includes an optional redundant (second) power supply, connect each of the two power supplies to different input power sources. Failure to do so makes the system susceptible to total power failure in the event that one of the power supplies fails.

Preventing ESD Damage

Electrostatic discharge (ESD) damage occurs when electronic cards or components are mishandled and can result in complete or intermittent failures. Note the following guidelines before you install or service the system:

•Always wear an ESD-preventive wrist or ankle strap when handling electronic components. Connect one end of the strap to an ESD jack or an unpainted metal component on the system (such as a captive installation screw).

•Handle cards by the faceplates and edges only; avoid touching the printed circuit board and connector pins.

•Place any removed component on an antistatic surface or in a static-shielding bag.

•Avoid contact between the cards and clothing. The wrist strap only protects the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Note For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Installing and Servicing the System

Follow these guidelines when installing and servicing the system:

•Disconnect all power and external cables before installing the system.

•Install the system in compliance with your local and national electrical codes:

–United States: National Fire Protection Association (NFPA) 70; United States National Electrical Code.

–Canada: Canadian Electrical Code, Part I, CSA C22.1.

–Other countries: If local and national electrical codes are not available, refer to IEC 364, Part 1 through Part 7.

•Do not work alone under potentially hazardous conditions.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

•Do not touch the backplane or midplane with your hand or metal tools.

•Remove all jewelry (including rings and chains) or other items that could get caught in the system or heat up and cause serious burns.

•Route cables away from field-replaceable components to avoid disconnecting cables unnecessarily when performing equipment maintenance or upgrades.
