Installation Considerations
Your installation site should be well-ventilated, clean,
and free of environmental extremes. There should be 2 to
3 feet of clearance at the front and rear of the cabinet in
which the carrier is to be installed to allow access for
installation of the power transformer unit, (optional) fan
module, and (optional) SDCP, as well as the network
interface connectors, rear connector plates, and DTE
cables.

performing installation
procedures, however, take
proper static control precautions
to prevent damage to

the proper static control
precautions, contact the nearest
