Power Supply

The AT-AR745 is available in two power supply configurations: a universal AC model and a 48 V DC model. The AC model includes an inlet for the

AR740 RPS (Redundant Power Supply). The AR740 RPS can be purchased separately, and each unit supports up to two AT-AR745 or AT-AR725 routers.

AT-AR745 AC AC models of the AT-AR745 have a universal AC input connector and a power switch on their rear panels. A DB25 connector for an optional external Redundant Power Supply (RPS), such as the AR740 RPS, is also located on the rear panel.

Pin outs for the DB25 RPS connector, and cable specifications for RPS supply cables, can be found in “Redundant Power Supply (RPS)” on page 14.

The router can monitor the PSU and the fan in both the router and the RPS. See “AR745 LEDs and what they mean” on page 15 for more information.

AT-AR745-80 DC The AT-AR745-80, designed for use by telecommunication carrier sites, supports connection to a 48 V DC power supply (in the range 39 V to 59 V DC). The DC model does not support an RPS connection, and does not support monitoring of the main PSU or fan.

DC supply cable specifications:

■Number of wires (cores): 3

■Minimum size: 2.1 mm2 (14 AWG)

■Minimum cable rating: 600 V, 90 degrees Celsius

DC power supply specifications:

■48 V DC (38 V to 60 V DC is acceptable)

■Either positive grounded or negative grounded

Safety Safety information and instructions outlining how to connect an AT- AR745-80 to a DC power supply can be found in the AR700 Series Router Installation and Safety Guide. You should read these instructions before attempting to connect the router to a DC power supply.

!Caution Some interfaces that may be installed in the router are not transformer isolated. This means they will be referenced to the frame ground of the equipment and may be damaged if connected to an interface on another piece of equipment which is at a different ground potential.
