Safety Warnings

Warning: See installation instructions before connecting the router. This is a summary of safety warnings. For a complete list of warnings for this router, including translations, see the ACX500 Universal Access Router Hardware Guide at

Caution: To comply with intrabuilding lightning and surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

Warning: The intrabuilding ports of the router are suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding ports of the router MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.

Caution: Before removing or installing components of a router, attach an ESD strap to an ESD point, and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router.

Caution: Use an external surge protective device (SPD) at the AC input of the router.

  • Only trained and qualified personnel should install or replace the router.
  • Perform only the procedures described in this quick start or the ACX500 Universal Access Router Hardware Guide. Other services should be performed by authorized service personnel only.
  • Read the installation instructions before you connect the router to a power source.
  • Before installing the router, read the guidelines for site preparation in the ACX500 Universal Access Router Hardware Guide to make sure that the site meets power, environmental, and clearance requirements for the router.
  • To prevent injury, keep your back straight and lift with your legs, not your back.
  • When removing or installing an electrical component, always place it component-side up on a flat antistatic surface or in an electrostatic bag.
  • When you install the router, always make the ground connection first and disconnect it last.
  • Do not work on the system 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.
  • Failure to observe these safety warnings can result in serious physical injury.
  • Power cable warning (Japan):


    Translation from Japanese—The attached power cable is only for this product. Do not use the cable for another product.

  • Note the hot surface warning label on the top rear of the chassis.
