Introduction
The Aprisa SR+ Protected Station is a fully monitored hot-standby and fully hot-swappable product providing radio and user interface protection for Aprisa SR+ radios. The RF ports and interface ports from the active radio are switched to the standby radio if there is a failure in the active radio. The Aprisa SR+ Protected Station is comprised of an Aprisa SR+ Protection Switch and two standard Aprisa SR+ radios mounted in a 2U rack mounting chassis.
All interfaces (RF, data, etc.) are continually monitored on both the active
and standby radio to ensure correct operation. The standby radio can be
replaced without impacting traffic flow on the active radio.
The Aprisa SR+ radios can be any of the currently available Aprisa SR+ radio
frequency bands, channel sizes or interface port options. The Aprisa SR+
Protected Station can operate as a base station, repeater station or remote
radio.
This guide provides a quick startup and basic installation instructions for
the Aprisa SR+ Protected Station shown in the next figure below.
A more detailed User Manual is also available. Refer to the User Manual for
important warnings, caution notes, and any detailed management relating to
fault, configuration, maintenance, performance monitoring, and security.

Install the Aprisa SR+ Protected Station and Connect the Protection Earth
The Aprisa SR+ Protected Station is designed to be mounted in a standard 19”
rack.
The Aprisa SR+ Protected Station has an earth connection point on the bottom
right of the chassis. Use the supplied M4 screw to earth the enclosure to a
protection earth.
The antenna feeder cable should use grounding kits for lightning protection as
specified or supplied by the coaxial cable manufacturer to properly ground or
bond the cable outer.
Note
When the spare Aprisa Protection Switch is supplied (APGS-XPSW-Xpp-FR-SA or
APGS-XPSW-Xpp-FR-DA where pp is the port option e.g. 22, 31, 40), the item
includes the Aprisa Protection Switch chassis, mounting brackets, 2x power
connectors, 1x remote control connector but no radios.
Note: The Aprisa SR+ radio operates within frequency bands that require a site license to be issued by the radio regulatory authority with jurisdiction over the territory in which the equipment is being operated. It is the responsibility of the user, before operating the equipment, to ensure that where required the appropriate license has been granted and all conditions attendant to that license have been met. Hereby, 4RF Limited declares that the Aprisa SR+ digital radio is in compliance with Directive 2014/53/EU. The full text of the EU Declaration of Conformity is available at the internet address www.4rf.com/library/en.
Connect the Antenna and Apply Power to the Aprisa SR+ Protected Station
Connect the antenna to the Protected Station antenna port (TNC female
connector). If the antenna is not available, terminate the TX/ANT A/B antenna
port with a TNC male 50-ohm terminator (10 Watts min). If the Protected
Station is the dual antenna option, then both TX/ANT A/B antenna
ports/terminators must be connected.
Warning: Do not directly connect the two radio antenna ports without attenuation of at least 40 dB. The receiver can be damaged if signals greater than +10 dBm are applied to the antenna port.
The Aprisa SR+ Protected Station version 2 operates on an input voltage of 10 to 60 VDC floating and consumes up to 42 Watts. Two power connectors (Molex 2-pin female) are supplied and fitted to the Protected Station. Wire your power source to the two power connectors (- / +) and plug the connectors into the Protected Station. The connector screws can be fastened to secure the connectors.
Note: The radio fuses will blow if the connected power supply is over voltage, or the polarity is reversed. Spare fuses are located on the Protection Switchboard (see the ‘Replacing Protection Switch Fuses’ section of the Aprisa SR+ User Manual). Turn your power source on. All the LEDs on both radios will flash orange for one second and then change to:
- • Active radio – the OK, MODE, and AUX LEDs will light green, and the TX and RX LEDs will light green (steady or flashing).
• Standby radio – the OK, TX, RX, and AUX LEDs will light green, and the MODE LED will flash green.
Connect to the Aprisa SR+ Protected Station (via SuperVisor or CLI)
Ensure that the Hardware Manual Lock switch is set to radio A (this is a
factory default setting). This prevents random switching when changing the
radio settings. The Aprisa SR+ primary radio (radio A) in the Protected
Station has a factory default IP address of 169.254.50.10 and the secondary
Aprisa SR+ radio (radio B) in the Protected Station has a factory default IP
address of 169.254.50.20, both with a subnet mask of 255.255.0.0.
-
Set up your PC for a compatible IP address e.g. 169.254.50.1 with a subnet mask of 255.255.0.0.
-

-
Open a browser and enter http://169.254.50.10.
Note: The Aprisa SR+ has a self-signed security certificate which may cause the browser to prompt a certificate warning. It is safe to ignore the warning and continue. The valid certificate is ‘Issued By: 4RF-APRISA’ which can be viewed in the browser. -
Log in to the primary radio with the default login ‘admin’ and password ‘admin’.
-
Each radio in the network and both radios in the Protected Station must be set up with unique IP addresses on the same subnet.
-
Set the Primary IP address and the Secondary IP address to network-compatible IP addresses. Set the Protected Station Virtual IP Address. This is the IP Address of the active radio used in both bridge and router modes. Set the Subnet mask and Gateway.
If the IP addresses of radios in the protected station are unknown for some
reason, they can be shown or changed via the Command Line Interface (CLI) on
the radio’s MGMT USB ports. USB to UART Bridge VCP Drivers are required to
connect the radio USB port to your PC. You can download and install the
relevant driver from www.silabs.com/products/development-tools/software/usb-
to-uart-bridge-vcp-drivers.
Set the PC serial port to 38,400 baud, 8 data bits, no parity, and 1 stop bit,
with no hardware flow control.
