4 Unit operation
4.1 Data and audio communications
4.1.1 PA/GA mounted using CAT6A cabling
When the Pbx is installed as an integral component
within the cabinet, it connects to the 2Mx matrix
controller via the IO bus. These are identified by the blue
CAT 6A cables which are connected between the rear of
the 2Mx and RJ45 connectors on the Pbx.
Each pair of CAT 6A cables provides a bidirectional data
& audio connection from the 2Mx to the Pbx. In the
event of either one of a pair of RJ45 cable becoming
disconnected the data & audio have a redundant path
ensuring the Pbx will continue to operate without any
loss of functionality. A flashing IO fault is logged on the
2Mx status display to warn of the fault and differentiate
it from any other internal cable loop fault.
4.1.2 PA/GA mounted using isolated audio and key line
cabling
When the Pbx is installed as a peripheral component,
it is connected to the IO-Tu and uses one of the lo-
unit’s audio & key line inputs. This allows the unit to be
situated inside the PAGA cabinet or outside with the
PABX system and connected using a 2 twisted pair +
screen cable.
4.2 Unit Status
The unit reports system status on the front panel LEDs.
The LED’s are grouped in pairs and generally shows up
to four states:
•
Green on, Red off – healthy
•
Red on, Green off – fault condition.
•
Green on, slow flashing Red – healthy, fault cleared
•
Green off, fast flashing Red – connection issues
ote:
N
Not all states are relevant for each pair of LEDs and some indi-
vidual LEDs may flash for specific functions (see the details below).
4.2.1 Power
The power LED is a simple power active indicator.
