Safety Warnings Summary

This is a summary of safety warnings. For a complete list of warnings, including translations, see the hardware documentation at

Warning: Failure to observe these safety warnings can result in personal injury or death.

  • Permit only trained and qualified personnel to install or replace device components.

  • Perform only the procedures described in this quick start and the hardware guide. Other services must be performed only by authorized service personnel.

  • Before installing the device, read the planning instructions in the hardware guide to make sure that the site meets power, environmental, and clearance requirements for the device.

  • Before connecting the device to a power source, read the installation instructions in the hardware guide.

  • Manually installing the device in a rack or cabinet at a height above 60 in. (152.4 cm) requires two people to lift the unit and install mounting screws. To prevent injury, keep your back straight and lift with your legs, not your back.

  • If the rack or cabinet has stabilizing devices, install them in the rack before mounting or servicing the switch in the rack or cabinet.

  • Before installing or after removing an electrical component, always place it component-side up on a flat antistatic mat or in an antistatic bag.

  • Do not work on the device or connect or disconnect cables during electrical storms.

  • Before working on equipment that is connected to power lines, remove jewelry, including rings, necklaces, and watches. Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the terminals.
