Hot Standby
When RipEX unit is used in RipEX-HS and Hot Standy is „On“ there are some limitations with it. Spe-
cifically, CD pin on COM1 and HW alarm Input and Output are used internally and not available to the
user. Neither Save nor Sleep modes can be activated. Please refer RipEX-HS User manual.
All settings below are valid only for RipEX units in RipEX-HS equipment, where two units in Hot Standby
mode are running. Both units MUST have the same settings! Only Unit names should be different as
this parameter is used in SNMP to recognize the sender of SNMP traps. In order to ensure that the
settings of both units are identical, it is recommended to set unit “A”, thereafter save its settings into a
file (Maintenance/Configuration/Save to file) and use these settings for unit “B”. (Maintenance/Config-
uration/Restore/File path/Upload) Finally, a unique Unit name should be assigned to Unit B.
List box: Off, On
Default = Off
When “On”, HW switching from RipEX unit “A” to RipEX unit “B” is performed based on the HW Alarm
Output settings in Settings/Alarm management. RipEX “A” is the primary unit, , Unit “B” is activated if
there is HW alarm on unit “A” or unit “A” power source is down or when Auto Toggle Period expired.
When mentioned events passed, RipEX “A” goes to be active again.
• MAC
Both units in RipEX-HS are using the same MAC addresses (MAC cloning). Whichever unit is active
(either “A or B”), RipEX Ethernet interface will use this MAC address. This MAC address has to be
unconditionally set to the same value in both units used in RipEX-HS. Otherwise, the switching
between units will not function properly.
Read own – it is possible to download the MAC address of this unit. The value in the second unit
has to be manually set to the same value then
• Auto Toggle mode
When Auto Toggle mode is On (HW button on front panel), controller automatically switches-over
to RipEX ”B“, even if “A” doesn't have any alarm and uses “B” for a set time in order to confirm that
RipEX ”B“ is fully ready-to-operate.
○ Start Date [YYYY-MM-DD]
Fill in the Date in the required format when Auto Toggle mode starts.
○ Start Time [HH:MM:SS]
Fill in the Time in the required format when Auto Toggle mode starts on ”Start Date“ day.
○ Period [min.]
Minimum value 60 min.
Within this period units “A” and “B” will change their activities over. Unit “A” starts to operate at
“Start Date and Time”. When “Period” minus “Unit B” time expires, controller switches to unit
“B”.
○ Unit B [min.]
Minimum value 5 min.
Time when unit “B” will be active within “Period”. It has to be shorter than Period by 5 min.
Time
List box: Manual, NTP
Default = Manual
Internal calendar time of RipEX can be set manually or synchronized via NTP (Network Time Protocol).
