The LEDs indicate the following:
Operational Information
The MT+S2M1-1 interface card can
be exchanged during operation, i.e.
without powering down the system.
However, the slot must first be deac-
tivated in the
Configurator in the
web console (see Installing Interface
Cards starting on page 25).
If the MT+S2M1-1 interface card is
being used in the master system of a
cascaded configuration, it can pro-
vide the system clock signal. Unless
otherwise specified, the system au-
tomatically selects an S
2M
card as
the clock signal source. For further
information, refer to
PBX Cascading
starting on page 98.
LED 1: Constantly yellow At least one connection established through the in-
terface card is active.
LED 2: Constantly green The interface card is operational; the slot has been
activated (flickering is normal).
Flashing yellow The interface card is ready, but the slot has not been
activated or the interface card has not been config-
ured yet.
Constantly red New software is being loaded onto the interface
card. If the LED lights up red for an extended period
of time, there may be a fault.
LED 3: Constantly green The interface card is providing the system clock sig-
nal (indicated only in the master system and only on
an interface card).
LED 4: – Not used
