When Hot Standby is “On”, Alarm thresholds and HW alarm input are used internally for switching
between units “A” and “B”. The “HW alarm input” parameter is changed to “Hot Standby active”.
Also HW alarm output for Temperature is always On. Its thresholds can be Manually set in interval
-50 to +90 °C (default -25 to +85 °C).
SNMP Alarm and Detailed Graphs tick boxes can be used for information about switching between
units “A” and “B”.

HW Alarm Output
List box: Off, N.O. (Normally Open), N.C. (Normally Closed)
Default = Off
If "
N.O.
" or "
N.C.
", the HW Alarm Output is active and its normal status (no alarm) is open or closed,
respectively.
The HW Alarm Output is a pin (open n-p-n collector) on the screw terminal at the Power and Control
connector on the front panel.
•
Detail Graph start
It has to be activated in Settings/Device/Graphs first.
You can tick here for which Alarm Detail Graph will be saved.

HW Alarm Input
List box: Off, N.O. (Normally Open), N.C. (Normally Closed)
Default = Off
If "
N.O.
" or "
N.C.
", the HW Alarm Input is active and its normal status (no alarm) is open or closed,
respectively.
Alarm event is triggered when the HW Alarm Input changes its status from “Normal” to “Alarm”.
Note that to “Close” the HW Alarm Input means connecting the respective screw terminal at the
Power and Control connector on the front panel to the Ground terminal of the same connector.

HW Alarm Input
List box: Off, On

When “
On
”, the Hardware Alarm Output indicates the full functionality of the RipEX. The Hardware
Alarm Output is down only when the RipEX is not powered or it is booting. When SNMP Trap and/or
Detail Graphs are ticked in the Unit ready line, the respective action is taken after every Hardware
Alarm Output state change (and also when the Apply button is activated after a reconfiguration).
The “
On
” setting of this parameter disables any other assignment to the Hardware Alarm Output.
The “Unit ready” parameter cannot be activated in the Hot standby mode, since the Hardware Alarm
Output controls the Hot standby switch.
Power management
•
Power supply mode
List box: Always On, Save Mode, Sleep Mode
Default = Always On
•
Always On
RipEX is always on, no special power saving modes are active.
•
Save Mode
When a RipEX is switched to the SAVE mode, it can be in one of two states – the SAVE state or
the ACTIVE state. In the SAVE state, the RipEX functionality is limited to listening to the Radio
channel in order to minimize the power consumption (approx. 2W). In the ACTIVE state, the RipEX
works normally, providing its full functionality (and consuming normal amounts of power).
Transitions between these states can be controlled by changes at the SI pin on the Power and
Control connector, by receiving packets on the Radio channel and by values of the SAVE mode
configurable parameters.
