Install the 7705 SAR-F in recommended equipment racks.
Install in clean, dry, ventilated, and temperature-controlled rooms.
Verify that the rack is properly bolted and braced and is properly grounded to a grounding
electrode.
Install the chassis in the equipment rack before installing SFPs.
The router and equipment rack must be properly grounded. Chassis ground cables are not
included. Lack of proper grounding (earthing) of the equipment may result in a safety
hazard and excessive electromagnetic emissions.
Before making the chassis ground connection, ensure that all power is OFF from the DC
circuit. To switch the power OFF, locate the circuit breaker on the panel board that
services the DC circuit and switch the circuit breaker to the OFF position.
Tip: For extra safety, tape the handle of the circuit breaker in the OFF position.
Electrostatic discharge (ESD) damage can occur if the router is mishandled. Always wear
an ESD-preventive wrist or ankle strap and always connect an ESD strap to a nearby
ground point that is connected to the site grounding point when working on the
7705 SAR-F. Typical ground points include the ground connection point on the front of the
7705 SAR-F, the grounding stud on the 7705 SAR-F mounting bracket, or a properly
grounded rack or work bench.
The 7705 SAR-F includes a chassis ground stud on the mounting bracket attached to the
right-hand side of the router (when viewed from the front). The chassis ground must be
connected to the building ground, using either a direct connection or a ground bus.
Do not use the chassis ground wire connection on the chassis ground stud for any other
purpose. That is, the washers and nut used to secure the chassis ground wire on the
ground stud must only be used for that purpose.
When wiring the unit, the chassis ground connection must always be made first and
disconnected last.
