system sends instructions to the control card, which in turn sends commands directing signal

These connections are used to connect to:
• A router control system using either

• The UniConfig application, installed
on a configuration PC.
• A system alarm that sends notification
of a system failure, such as a fan mal-
function.
• A power supply alarm that sends notifi-
