Only the controller version of the RipEX2-HS is supported, where the controller manages the active and passive/standby RipEX2 units and their accessing to the shared channels (e.g. radio).
The communication between individual RipEX2 units and HS controller use DI/DO interfaces, so other use of this interface is not possible.
The HW switch (mode selector) has to be set to AUTO position for switching between units, otherwise the selected unit remains active even if an error occurs on the selected one.
AUTO regime allows switching to the standby unit when an error status occur in active unit – if both units are without alarms, the A unit will be active.
Menu ADVANCED/Device/Unit menu/Hot Standby
(HotStdby_Enable): Listbox: “On”, “Off” (default). Switches Hot Standby functionality.
(HotStdby_Mac): MAC address of shared LAN interface. It should be same for both individual RipEX2 units. This MAC address has to differ from other MAC addresses used in unit. It is possible to use e.g. VRRP type of addresses: 00:00:5E:00:01:XX.
(HotStdby_Ip): This address has to fit into range of addresses used for the relevant network interface (e.g. ETH 1) and will be used as shared IP address for LAN interface. The radio address use used according to setting in SETTINGS/Interfaces/Radio/IP – the same address has to be set in both radio modems.
Unit chassis position
(HotStdby_MasterMode): Listbox “Unit A”, “Unit B” (default) – position of the unit in HS chassis, set Unit A for unit in A position and vice versa.
(HotStdby_FallbackTime): Time in seconds. The time delay to stay on the standby unit, after all alarms are solved.
(HotStdby_Guard_Mode): Listbox: “INCLUDE” (default), “EXCLUDE”. Defines the behavior of guarding of ETH interfaces. INCLUDE requires all guarded lines in UP status – if one of these guarded lines is not in UP state, alarm occurs and the switching to the standby unit is executed.
Guard ETH1 .. ETH5 active
(HotStdby_GuardETH_1_Enable .. HotStdby_GuardETH_5_Enable): Listbox: “On”, “OFF” (default). Switches on guarding of the individual ETH link.
It is possible to change the active status from the A to the B unit using shall command “rrcmd rrhstdby web passivate” and back from A to B using command “rrcmd rrhstdby web activate”. Both units should be without errors for the SW switching.
Setting of LAN interface
It is necessary to set LAN interface used for HS functionality.
The parameter Range for virtual address has to be set to On for the LAN address interconnected with shared ETH (usually ETH1) interface.
ETH1 addresses of both A and B units should be different, but in the same range as the virtual shared address (= together three different addresses in the same range).
