ZyXEL EM422 2 Port 10-GbE XFP Module, 24 Dual Personality Gigabit Ports, 2 Built-in 12G Stacking Interfaces

Unique 24 GbE Copper and Fiber connectivity in a 1U-height Design. The leading architecture of xGS-4528F delivers 24 1000Base-T copper interfaces with standard RJ-45 connectors and 24 SFP slots in a 1U, 19" enclosure, this unique benefit gives network designers the highest flexibility and cost saving from equipment investment, network administration and maintenance.

Built-in Stacking Ports Eliminate Hidden Cost on Network Expansion. With the two high performance 12G stacking ports on back panel, over 10 units of xGS-4528F can be easily hard-stacked in a ring architecture, this feature makes xGS-4528F highly scalable and eases the network expansion and administration. Moreover, these two stacking ports come with every xGS-4528F unit, customers have no need to spend extra expense for buying stacking modules and stacking cables.

True Wirespeed L3 Switching for High Performance Network. Each xGS-4528F provides 144Gbps switching capacity, wirespeed performance is delivered on all GbE copper/fiber ports within the stack, as well as stacking ports and optional 10G uplinks. Advanced L3 switching, multicasting, resiliency including OSPF, DVMRP, VRRP help deliver optimal performance for entire network.
