Digital Input and Digital Output for External Alarm
The GS-5220-16T4S2XR is particularly equipped with one 100~240V AC power supply
unit and one 36~60V DC power supply unit to provide an enhanced reliable and
scalableredundantpowersupply.Thecontinuouspowersystemisspecicallydesigned
tofulllthedemandsofhigh-techfacilitiesrequiringthehighestpowerintegrity.Withthe
36~60V DC power supply, the GS-5220-16T4S2XR is able to act as a telecom-level
device that can be located in the electronic room.
Solution for IPv6 Networking
By supporting IPv6/IPv4 dual stack and plenty of management functions with easy and
friendly-user interfaces, the GS-5220 series is the best choice for IP surveillance, VoIP
and wireless service providers to deploy the IPv6 network. It also helps the SMBs to
step in the IPv6 era with the lowest investment but not necessary to replace the network
facilities while the ISPs construct the IPv6 FTTx edge network.
