Power Indicator
The power indicator will light green when power is applied. If the indicator does not light
when power is applied then check the power supply connections.
Network Indicator
The network indicator reports the status of the connection to the network. When pow-
ered up the indicator will be off, the indicator will then flash green whilst the unit search-
es for a network, once connected to the network the indicator will light green.
Status Indicator
The status indicator reports the health of the unit. In normal operation the indicator will
be green, if a fault is detected either at boot-up or during normal operation the indicator
will light red. When the unit is first switched on or is reset the indicator will first light
red, then flash red in sequence with the Signal Strength Indicator, this is normal behaviour
during boot-up and does not indicate a fault.
