TESSERA - V3.0 | USER M ANUAL - REV B | 4.3 - REDUNDANCY CONFIGURATION
Fig 4.2 - Redundancy options on the Network tab for Tessera LED Processors
The Network tab includes the loop status indicator and a load bar for a redundant output pair
on ports 1 and 2. Ports 3 and 4 continue to operate independently without redundancy.
N OTE The system load will double when redundancy is enabled, this is because twice the
am ount of bandwidth is needed to ensure prim ary and backup signals are
m aintained.
In the Tessera SX40 , 10Gb trunk pairs can be (independently) configured for redundant
operation (A+B, C+D) however sym m etry m ust be m aintained.
