Protected Station
This section documents the Aprisa SR+ Protected Station which is used as the protected base station for
Aprisa SRx radios. The ‘SR Compatible’ option must be enabled on the Aprisa SR+ Protected Station radios
(see ‘SR+ Compatible’ on page 220).
The majority of SuperVisor screens are the same for the standard Aprisa SR+ radio and the Aprisa SR+
protected station. The following screens are specific to the protected station.
Logging into a Protected Station
When SuperVisor detects a protected station, it operates in Single Session Management operation mode.
When in Single Session Management mode, SuperVisor will automatically detect the two individual Aprisa
SR radios configured to pair together for protection, and manage the two units in a single browser session.
To the user, it will appear as managing a single unit, but SuperVisor will interact with the two individual
units at a lower level.
The user can login with the IP address of either the Primary or Secondary radio to manage the protected
station (don’t use the PVIP address as it is not a management IP address). SuperVisor will present all
information appropriately where ‘Common Parameters’ will be presented to the user as a single
parameter e.g. TX and RX Frequencies and ‘Unit Specific Parameters’ will be presented to the user as
Primary or Secondary parameters e.g. Events and Alarms.
When saving data, SuperVisor will also validate and ensure that the correct settings are written to both
units. The SuperVisor Single Session Management ensures that both units of the protected station are
always configured correctly to complement each other as protected partners.
The user can still login with two different sessions to the active and standby radios. If the user opens two
session management, one session logged into the active radio and a second session logged into the standby
radio, the Multiple Management Sessions pop-up message will show the user names and IP addresses of the
active and standby radio.
Parameter Errors
On protected station screens, parameter values displayed in red indicate discrepancies in common
parameter values between the primary and secondary radios (see ‘Protected Station: Terminal >
Summary’ on page 216 for an example of the red display). The value displayed is from the ‘addressed
radio’.
These value discrepancies can occur if the two protected station radios have been separately configured.
The discrepancies can be corrected by re-entering the values in one of the radios. The value will be
copied to the partner radio.
