תאור

DES-1026G - unmanaged switch 10/100 Mbit / s , designed to improve the performance of the working group , provides a high level of network flexibility . The presence of 24 -port 10/100 Mbit / s to connect workstations and two Gigabit combo ports for connecting servers allow you to meet the needs of a large network bandwidth and reduce response time.
 
24-port 10/100 Mbit / s to connect workstations
The switch features 24 ports of 10/100 Mbit / s and can be used to connect to the small workgroup . These ports support auto-negotiation speed 100BASE-TX and 10BASE-T auto-negotiation mode and full and half-duplex .
 
2 Gigabit combo ports
Switch is equipped with 2 combo ports to connect to servers over twisted pair or core switches using fiber optic cable. Using existing Category 5 twisted pair as a transmission medium can immediately connect servers to ports Gigabit Ethernet, without requiring you to install new fiber optic cable . These ports support auto-negotiation 10/100/1000 Mbit / s and auto-negotiation . With the help of these ports can also be connected to multiple switches , together with a view to increasing the number of ports destined for network connections.
 
Flow control for secure information transfer
All ports support flow control by the " back pressure " and IEEE 802.3x. These functions allow you to avoid packet loss buffer overflow port of the receiving device .
 
Auto detect cable polarity MDI / MDIX
All ports support auto- polarity cable MDI / MDIX. This eliminates the need for crossover cables or ports uplink. To any port to connect the server , a router or a switch , using straight-through twisted-pair cable .
 
Feature «Plug-and-Play»
Switch with 26 ports «plug-and-play» is an ideal choice for workgroups to increase productivity applications " client / server ".
