RipEX Hot Standby



  • Two booted-up standard RipEX units inside
  • Two independent power supplies
  • Automatic switch-over (< 2 s)
  • 4x HW alarm output
  • Internal fans
  • Back-up battery pack
  • 19″ rack 3U
RipEX-HS is designed to be used at critical sites, where high HW reliability is required – typically master or repeater stations.
RipEX-HS is hot standby, 1+1 redundant, fully monitored, hot swappable equipment.
RipEX-HS is assembled with 2 standard RipEX units, each powered by its independent power supply. A controller takes care of automatic changeover in case of failure. Changeover conditions are widely configurable. Since both units are hot-stand-by and use identical MAC addresses, exceptional switch-over time of less than 2s is achieved.
LED panels, Mode buttons, HW alarm outputs, SNMP traps and standard RipEX units inside makes RipEX-HS configuration and control quite easy and maintenance can be done by anyone familiar with RipEX.

There are 2 standard RipEX units with identical configurations inside of RipEX-HS. Both units are booted, however only one is active. The interfaces (COM1, COM2, Ethernet, Radio) of second unit are disconnected.

When the active unit HW alarm output changes to “On” (when a controlled value exceeds the respective threshold), the controller automatically switches all interfaces (COM1, COM2, ETH, ANT – if applicable) to the second unit and it takes over all functions. Since both units are using the same MAC addresses (MAC cloning), there is a minimal drop-out while switching, less than 2s.

Possible controlled values are:
RSS, DQ, TXLost[%] – lost packets on Radio channel, Ucc – power voltage, Temp – inside temperature, PWR – RF power, VSWR – reflected RF power, ETH[Rx/Tx], COM1[Rx/Tx], COM2[Rx/Tx] – No of received/transmitted packets on respective interfaces
SNMP trap with each switch-over can be sent (depending on configuration) to central SNMP management.

Block diagram

  • Auto – primary active is RipEX „A“, when it fails, controller automatically switches-over to RipEX „B“
  • Auto toggle – the same as Auto mode, in adition after set time controller automatically switches-over to RipEX „B“, even if “A” doesn’t have any alarm and uses “B” for set period in order to confirm, that RipEX „B“ is fully ready-to-operate
  • A – only RipEX “A” is active and controller will never switch to RipEX „B“
  • B – only RipEX “B” is active and controller will never switch to RipEX „A“
  • Every single unit tested in a climatic chamber as well as in real traffic

  • Approx. 10 hours of RipEX-HS operation
  • 4 HW alarm outputs available on the screw terminal connector on the rear panel
  • Standard RipEX HW alarms of units “A” and “B”
  • Switch HW alarm informs of active unit failure and controller switch-over to the back-up unit
  • Power alarm informs of controller board power drop-out
  • Different HW models
  • By default single antenna connector connected to the active unit
  • Available model with separate “A” and “B” antenna connectors whenredundant antennas are used
  • When RipEXes with separated Rx and Tx antenna connectors are used, the RipEX-HS provides Rx and Tx antenna connectors always connected to the active unit
  • Model offerings
  • RipEX-HS is supposed to be delivered from factory with RipEX units (on separate order) assembled
