Chapter 4: Installing E-series Routers
Safety Guidelines
Observe the following safety guidelines when mounting the router in a rack.
WARNING: Install equipment in the rack from the bottom upward. This will
maintain the stability of the rack and reduce the chance that the rack will tip over.
WARNING: Three people are required to install the E-series router in a rack: two to
lift the system into position and one to screw it to the rack.
CAUTION: Evaluate the overall loading of the branch circuit before you install any
equipment into a rack.
WARNING: Connect the E-series 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 E-series 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 may cause electric shock and serious burns.
WARNING: The ERX-310 router AC model has more than one power-supply cord.
Disconnect 2 power cords BEFORE servicing to avoid electric shock.
