AR700 Series Router

AT-AR725-80 DC The AT-AR725-80, designed for use by telecommunication carrier sites, supports connection to a 48V DC power supply (in the range 39 to 60 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- AR725-80 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.

AC models of the AT-AR725 can be used in conjunction with the AR740 RPS. Each AR740 RPS can provide power supply and mains circuit redundancy for up to two AT-AR725s or AT-AR745s. For more information on the AR740 RPS, see “AR740 RPS Redundant Power Supply (AT-AR725,AT-AR745 only)” on page 43.

For connection to an AR740 RPS, the AT-AR725 router has a female DB25 connector on its rear panel (Figure 3). Pin outs for the connector are listed in Table 2.
