Installing ERX Routers

CAUTION: Evaluate the overall loading of the branch circuit before you install any equipment into a rack.

WARNING: Connect the router or rack to ground (earth), and ensure that a reliable grounding path is maintained in the rack.

WARNING: Do not work on the system or connect or disconnect cables during lightning activity.

WARNING: Be sure circuit breakers for the power source are in the OFF position before attaching power cables.

WARNING: Before servicing the router, turn off the power.

WARNING: Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the terminals.

WARNING: Do not insert any metal object, such as a screwdriver, into an open slot or the backplane. Doing so can cause electric shock and serious burns.

WARNING: The ERX-310 router AC model has more than one power-supply cord. Disconnect two power cords before servicing to avoid electric shock.
