GS-5220-16S8C/R
2
Redundant AC / DC Power Supply to Ensure Continuous Operation
The GS-5220-16S8CR 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 installation. The continuous power system is specifically
designedtofulllthedemandsofhightechfacilitiesrequiringthehighestpowerintegrity.
With the 36~60V DC power supply, the GS-5220-16S8CR is able to act as a telecom
level device that can be located in the electronic room.
Effective Alarm Alert for Better Protection
The GS-5220-16S8C and GS-5220-16S8CR support a Fault Alarm feature which can
alert the users when there is something wrong with the switches. With this ideal feature,
theuserswouldnothavetowastetimetondwheretheproblemis.Itwillhelptosave
time and human resource.
Solution for IPv6 Networking
Faced with the increasingly large number of IP cameras and wireless APs installed and
deployed in all kinds of applications, more and more network facilities start to support
the IPv6 protocol for the next-generation networking. By supporting both the IPv4
and IPv6, and numerous management functions with easy and friendly management
interfaces, the GS-5220-16S8C and GS-5220-16S8CR are the best choices for IP
surveillance and wireless service providers to connect with the IPv6 network.
