10/100Mbps Unmanaged Switch With Gigabit Connections
DES-1026G
The DES-1026G switch provides 24 auto-sensing
10/100Mbps ports and 2 10/100/1000Mbps copper
Gigabit ports in a rack-mount box. The switch allows
mix and match of Ethernet, Fast Ethernet and Gigabit
in full- and half-duplex modes.
24-port 10/100Mbps Switch With 2 Built-in Copper
Gigabit Connections
The DES-1026G is an unmanaged 10/100Mbps switch designed to enhance workgroup performance while providing a high level
of flexibility. It provides 24 10/100Mbps ports for workstation connection, plus 2 copper Gigabit ports for server deployment,
allowing a workgroup to multiply bandwidths, boost response time and satisfy heavy load demands.
24 10/100Mbps Ports for Workstation Connection
The switch comes with 24 10/100Mbps ports, allowing a
small workgroup to flexibly integrate to Ethernet and Fast
Ethernet. These intelligent ports detect the network speed and
auto-negotiate between 100BASE-TX and 10BASE-T, as well
as between full and half-duplex.
2 Copper Gigabit Ports for Server Connection
2 copper Gigabit ports provide an inexpensive alternative
solution to fiber-optic. Using your existing low-cost Cat. 5
copper twisted-pair wires as the transmission media, these
ports allow you to instantly upgrade your servers to Gigabit
capability without requiring you to install new, expensive
fiber cables. Both ports support 10/100/1000Mbps network
speed auto-sensing and full/half duplex auto-negotiation.
Flow Control for Secure Transmission
All ports support flow control. This function minimizes
dropped packets by sending out collision signals when the
port's receiving buffer is full.
Auto-negotiation of MDI/MDIX Cross Over
All ports support auto-negotiation of MDI/MDIX cross
over. This eliminates the need for cross over cables or
uplink ports. Any port can simply plug to a workstation, a
server, a hub or a switch, using the usual straight-through
twisted-pair cable.
Plug-and-Play
With 26 plug-and-play ports, the switch is a perfect choice
for workgroups to upgrade performance in a client/server
environment. The ports can be connected to workstations
and servers in full-duplex, or hubs in half-duplex.
