How to Communicate Using the A-Link
The Rack Air Removal Unit can be used with an APC Environmental Management System that can
monitor and control the unit. Connect the APC Environmental Management System any Rack Air
Removal Units by using the in and out A-Link connections.
How to connect to the A-Link
The Rack Air Removal Unit has two connections (IN and OUT) for linking several devices together
using the A-Link. The Rack Air Removal Unit must be given an address to communicate with the
APC Environmental Management System. The address DIP switch is recessed inside the space
marked A-Link Address. Use a small tool such as a pocket screwdriver to set the DIP switch to the
correct position.
To remotely monitor the Rack Air Removal Unit:
1. Set the second, third, and fourth DIP switches to
give the Rack Air Removal Unit a unique A-Link
address between one and eight, according to the
chart.
Warning
Remove power from the Rack Air Removal Unit before setting DIP switches or
connecting other devices.
