1.2.2 Features and Benefits
Various Interfaces
DG-GS4928F provides 12 1000Mb fiber ports, 12 1000Mb Combo ports (1000Mb
fiber SFP ports/1000Mb copper ports) and 2 slots with the extended cards.
Secure Power Supply
DG-GS4900 series switches provide DC/AC power backup, support 220V AC input,
48V DC input, 12V DC input, 220V AC, 48V DC input simultaneously or 220V AC, 12V DC
input simultaneously.
Support 10Gb Ethernet
10Gb Ethernet which adopts full-duplex technology instead of low-speed, half-duplex
CSMA/CD protocol, is a big leap in the evolution of Ethernet. 10Gb Ethernet can be
deployed in star or ring topologies. DG-GS4900 series switches provide broad bandwidth
and powerful processing capacity. It is suitable for metropolitan networks and wide area
networks. Using DG-GS4900 series switches, users can simplify network structures and
reduce cost of network construction.
Networking Protocols
DG-GS4900 series switches support 802.1d/w/s, 802.1Q, 802.1p, 802.3ad, 802.3x,
GVRP, DHCP and SNTP etc. The switches also support the multicast protocols such as
IGMP, DVMRP and PIM. Moreover, DG-GS4900 series switches support RIPv1/2, OSPF,
BGP and IPv6 protocols. All these protocols supported enable DG-GS4900 series
switches to meet the requirements of complex network constructions.
ACL
DG-GS4900 series switches support comprehensively ACL policies. The traffic can
be classified by source/destination IP addresses, source/destination MAC addresses, IP
protocols, TCP/UDP, IP precedence, time ranges and ToS. And various policies can be
conducted to forward the traffic. By implementing ACL policies, users can filter the virus
