APX 1000™ Getting Started Guide
Safety-Related Electrical, Physical, and Environmental Information
Electronic and electrical specifications
Electrical requirements
The APX 1000 can be powered from a dc or ac power source, or both. The power source is
wired to the power supplies on the right side at the rear of the chassis. Although a single ac or
dc power supply is sufficient to operate the unit, it can be equipped with two power supplies of
either type, or one power supply of each type in combination.
Table D-1 lists the APX 1000 electrical requirements.
Because the APX 1000 configuration profiles are stored in NVRAM, they are not lost when
the unit is turned off.
Ground wire size
Table D-2 lists the chassis ground wire specifications for APX 1000 units.
