Fig 4.4 - Tessera SX40 configured with redundancy for trunks A and B and C and D
When operating in redundancy m ode:
l
Fixtures can be cabled in a single chain of up to 50 fixtures, with each end of the chain
connected back to the processor (or Tessera XD when using a Tessera SX40). Ethernet
switches m ust not be used to split the signal. Other Ethernet hardware (such as fibre
extenders) are supported.
l
Closed loop redundancy should be enabled on the processor.
l
The output capacity lim its that apply to a single port also apply to the pair of ports. This
effectively halves the overall processor capacity, as each output signal is being 'doubled
up'. This also applies to Tessera SX40, therefore twice the am ount of Tessera XD Units
would be required.
l
The total network load for the two ports com bine into a single bar indicating the load for
that pair.
l
Switching in and out of redundancy m ode will m om entarily black-out the video signal for
all connected fixtures on all ports. Redundancy m ode should be configured in advance.
l
The active feed (prim ary or backup) used by each fixture can be viewed in the Online tab.
l
If both the prim ary and backup signals are operational, each fixture can alternate between
either signal. If a fixture receives a video error or com plete signal loss from one port, it
will switch to the backup port for the next fram e.
l
For Tessera S8, S4, and M2 LED Processors, each loop m ust be cabled between the two
adjacent ports on the sam e processor. (I.e. Port 1 to Port 2, and Port 3 to Port 4.)
l
For Tessera SX40, the loop is created using the sam e trunk port num ber in two adjacent
Tessera XD Units (i.e. Trunk A to Trunk B, and Trunk C to Trunk D)
