Installation Guidelines and Requirements
WARNING: Do not insert any metal object, such as a screwdriver, into an open slot
or the backplane. Doing so might cause electric shock and serious burns.
WARNING: Three people are required to install the router in a rack: two to lift the
system into position and one to screw it to the 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.
CAUTION: Evaluate the overall loading of the branch circuit before you install
any equipment into a rack.
