Highly-reliable Stacking Ability
Through its up to 40Gbps, bi-directional high bandwidth tunnel and stacking technology,
the SGS-5220-24P2X gives the enterprises, service providers and telecoms flexible
control over port density, uplinks and switch stack performance. The stack redundancy
of the SGS-5220-24P2X 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.
Centralized Power Management for Gigabit Ethernet PoE Networking
TofullltheneedsofhigherpowerrequiredPoEnetworkapplicationswithGigabitspeed
transmission, the SGS-5220-24P2X features high-performance Gigabit IEEE 802.3af
PoE (up to 15.4 watts) and IEEE 802.3at PoE+ (up to 30 watts) on all ports. It perfectly
meetsthepowerrequirementofPoEVoIPphoneandallkindsofPoEIPcamerassuch
as IR, PTZ, speed dome cameras or even box type IP cameras with built-in fan and
heater for high power consumption.
The SGS-5220-24P2X’s PoE capabilities also help to reduce deployment costs for
network devices as a result of freeing from restrictions of power outlet locations.
Power and data switching are integrated into one unit, delivered over a single cable
and managed centrally. It thus eliminates cost for additional AC wiring and reduces
installation time.
Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the SGS-5220-24P2X features
intelligent PoE Management functions:
■PDALIVECheck
■ScheduledPowerRecycling
■SMTP/SNMPTrapEventAlert
■PoESchedule
Intelligent Powered Device Alive Check
The SGS-5220-24P2X can be configured to monitor connected PD (Powered Device)
status in real-time via ping action. Once the PD stops working and it is without
response, the SGS-5220-24P2X will resume the PoE port power and bring the PD back
to work. It will greatly enhance the network reliability through the PoE port resetting the
PD’s power source, thus reducing administrator management burden.
