DES-1009GEOL EOS

8-Port 10/100 Mbps Ethernet Switch with Gigabit Uplink

Tanımlama

The DES-1009G  is  a  Gigabit  Switch  with  eight 10/100 Mbps N Way Ethernet ports and one 1000 Mbps Gigabit Ethernet port. The DES-1009G provides a workgroup solution helping to increase network throughput for increased server to client response.  The DES-1009G is targeted at small to medium corporate business environments .

The DES-1009G strictly adheres to IEEE 802.3 10BASE-T, IEEE 802.3u 100BASE-TX, and IEEE 802.3z 1000BASE-TX standards. It  utilizes  the  same  packet  structure  format  support  for  the CSMA/CD  protocol. In addition, the DES-1009G supports full duplex  and  flow  control.  The  DES-1009G  delivers  high-speed 10/100 Mbps Fast Ethernet switching and maximum flexibility by providing dynamic auto-sensing capabilities for 10/100/1000Mb Ethernet segments and workstations.

The DES-1009G utilities a store and forward switching scheme to support rate adaptation and protocol conversion. The DES-1009G supports non-blocking full wire speed data forwarding and filtering rate capabilities for each port. The DES-1009G also has built-in N Way  auto-negotiation  ports, which  automatically  identify  and determine the correct transmission speed and duplex mode of the attached device.

The DES-1009G provides dynamic filtering through auto-learned MAC addresses and static filtering. In addition, The DES-1009G comes with a 4096 active MAC address entry table and hashing algorithm on address learning per device. The DES-1009G enables auto-aging  capabilities  and  collision  backpressure.  The  DES-1009G supports buffering allocation of 512 bytes each to optimize the performance on mixed network speeds.

Finally, the DES-1009G can help to protect a LAN from broadcast storms through rate filtering, which can control broadcast data and prevent unnecessary absorption of network bandwidth to keep the network speed constant. The DES-1009G provides 3 LEDs per port to connection speed, port status, and network activity. Additional switch LED, report real-time HTTP, ICQ and SMTP traffic.
