Efficient Single IP Management
The SGS-5220 series applies the advantage of the stacking technology to managing
the stack group with one single IP address, which helps network managers to easily
manage a stack of switches instead of connecting and setting each unit one by one.
The stacking technology also enables the chassis-based switches to be integrated into
the SGS-5220 Managed Switch series at an inexpensive cost.
Highly-reliable Stacking Ability
Through its up to 40Gbps, bi-directional high bandwidth tunnel and stacking technology,
the SGS-5220-24T2X gives the enterprises, service providers and telecoms flexible
control over port density, uplinks and switch stack performance. The stack redundancy
of the SGS-5220-24T2X ensures that data integrity is retained even if one switch in
the stack fails. You can even hot-swap switches without disrupting the network, which
greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth
demands.
Cost-effective 10Gbps Uplink Capacity
10G Ethernet is a big leap in the evolution of Ethernet. The two 10G SFP+ slot of the
SGS-5220-24T2X supports Dual-speed, 10GBase-SR/LR or 1000Base-SX/LX, meaning
the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according
to the transmission distance or the transmission speed required to extend the network
efciently.TheygreatlysupportSMBnetworktoachieve10Gbpshighperformanceina
cost-effective way because 10GbE interface usually could be available in Layer 3 Switch
but Layer 3 Switch could be too expensive to SMBs.
