Prestera
-FX9110/FX9210 Crossbar Switch Fabric
APPLICATIONS
As illustrated below in Figure 2, a high performance, non-blocking 144 GbE enterprise core chassis switching system can be
designed with twelve 12 GbE line cards. As many as 576 GbE ports may be supported in a fully conTgured 12-blade chassis.
These solutions accelerate the proliferation of Gigabit switching in the enterprise environment. Up to multiple Prestera-FX9110/FX9210
crossbar switch fabrics can be conTgured to work in parallel for increased system performance and/or availability. In an active/
standby conTguration, shown in Figure 3, one fabric is active while the other is in standby mode, waiting to take over if the active
crossbar fails or is removed from the system.
