Before installing the router, read the guidelines for site preparation in the ACX710 Universal Metro Router Hardware
Guide at https://www.juniper.net/documentation/
requirements for the router.
For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow at least 6 in.
(15.2 cm) of clearance between side-cooled routers. Allow 2.8 in. (7 cm) between the side of the chassis and any
non-heat-producing surface, such as a wall.
When installing the router, do not use a ramp that is inclined more than 10 degrees.
Manually installing the router requires two people to lift an empty chassis and three people to lift a fully configured
router. Before lifting the chassis with only two people, remove the components as described in the ACX710 Universal
Metro Router Hardware Guide at https://www.juniper.net/documentation/. 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.
Mount the router at the bottom of the rack if it is the only unit in the rack.
When mounting the router in a partially filled rack, load the rack from the bottom to the top with the heaviest component
at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the router in the rack.
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.
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. Always connect the ground wire 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.
