TSL TM1 Mk3+ - What Do I Need to Build a Redundant System; Main Hardware Requirements

11
What do I need to build a redundant system?
To create a redundant system, you need:
• 1 x Redundancy licence
• 2 x TallyMan TM1-MK3+ controllers
• 1 x Direct Link cable to connect the controllers
• 1 x TMRP unit
• Associated networking, power supplies and cables.
Main hardware requirements
There are two possibilities, depending on whether you already have a system built around a TallyMan
TM1-MK3+:
• TallyMan Redundancy Package
• TallyMan Redundancy Kit
TallyMan Redundancy Package
If you do not already have a system based on a TallyMan TM1-MK3+ system, you can purchase a
complete TallyMan Redundancy Package, which contains the following:
• 2x TM1-Mk3+ system controllers
• 1x TallyMan Redundancy Kit (see below)
Tallyman Redundancy Kit
If you already have a system based around a single TallyMan TM1-MK3+ controller, you will need to
purchase a second TallyMan TM1-MK3+ controller, along with the TallyMan Redundancy Kit which
contains the following:
• 1 x Redundancy licence
• 1 x Direct Link Cable to connect 2x TM1-MK3+ units for auto negotiation and synchronisation
• 1 x TMRP 4-button LCD control panel to monitor and manage automatic/manual failover from
anywhere in your network. Has external triggers for local alarming and controlling external
switchboxes to switch physical I/O
• 1x TMRP 1RU mounting panel
• 1x TMRP power supply
The TM1-Mk3+ units are designated by the user as either the Primary or the Backup. The Primary unit is
the unit that is expected to be in use during normal operation. The Backup is placed into Standby to
monitor the Primary; in the event of a failover the Backup will become active while the Primary will
deactivate.
During normal operations the Primary and Backup units are synchronised with all relevant state changes
so that in the event of a Failover the Backup can continue the control operations. Note that when the
Backup is Active, the Primary unit is no longer synchronised with the Backup so it is possible some states
will not be same between the units. When the Primary is restored to being the Active unit the Backup will
synchronise with the Primary again.
