Safety Warnings


This is a summary of the safety warnings. For a complete list of warnings, see the JA2500 Junos Space Appliance Hardware Guide.


Failure to observe these safety warnings can result in serious physical injury.

  • Permit only trained and qualified personnel to install or replace the JA2500 appliance.

  • Perform only the procedures described in this quick start and the JA2500 Junos Space Appliance Hardware Guide. Other services must be performed only by authorized service personnel.

  • Before installing the appliance, read the planning instructions in the JA2500 Junos Space Appliance Hardware Guide to make sure that the site meets power, environmental, and clearance requirements for the appliance.

  • Before connecting the appliance to a power source, read the installation instructions in the JA2500 Junos Space Appliance Hardware Guide.

  • Installing a JA2500 appliance requires one person to lift the appliance and a second person to install the mounting screws.

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

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

  • Do not work on the appliance 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.

  • When you install the appliance, always make the ground connection first and disconnect it last.

  • Wire the DC power supply using the appropriate lugs. Always connect the ground wire first and disconnect it last.

  • AC-powered devices are shipped with a three-wire electrical cord with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding must comply with local and national electrical codes.

  • AC power cable warning (Japan):


    The attached power cable is only for this product. Do not use the cable for another product.
