■ When installing the router, do not use a ramp inclined at more than 10 degrees.
■ Manually installing the router requires two people to lift. To prevent injury, keep
your back straight and lift with your legs, not your back. Do not attempt to lift
the chassis by the power supply handles.

the rack.

to the top with the heaviest component at the bottom of the rack.

mounting or servicing the router in the rack.

component-side up on a flat antistatic surface or in an electrostatic bag.

and disconnected last.
■ Wire the DC power supply using the appropriate lugs. When connecting power,
the proper wiring sequence is ground to ground, +RTN to +RTN, then -48 V to
-48 V. When disconnecting power, the proper wiring sequence is -48 V to -48 V,
+RTN to +RTN, then ground to ground. The ground wire should always be
connected first and disconnected 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,

terminals.
