Department Security and
QoS Switch
With the security and QoS
features, it improves the
network to be efficiency
and protects the network
clients. With the four SFP
ports, the GSW-4804SF
provides the uplink to the
backbone network through
Gigabit Ethernet LX / SX SFP
modules. With the security,
Multicast IGMP Snooping
and QoS features, it improves
the network’s efficiency and
protects the network clients.
