Live-GSH5T Gigabit Ethernet Switch is an auto-sensing and auto-negotiating Gigabit Ethernet 
Switch with Broadcast Storm Control capability.  Its five 10/100/1000Mbps Gigabit ports provide 
10/100/1000Mbps connections to PC with gigabit cards or gigabit switches  
 
Live-GSH5T’s unique switching fabric provides non-blocking full wire speed for all ports.  Auto 
MDI/MDIX function is provided for conventional uplinking to another switch/hub using ordinary 
straight-through cable.  Each port provides up to 2000Mbps in full duplex mode. With its 
auto-sensing, Live-GSH5T automatically detects the speed of the devices you plug into, and routes 
the incoming data to its destination. Its auto-negotiating function allows existing devices running at 
different speeds to communicate easily within the same network. 
 
 
 

 
The Live-GSH5T automatically filters out the broadcast traffic when the broadcast packets exceed 
5% of the total traffic.  Broadcast storm can significantly impede the performance of the network.  
The Live-GSH5T protects your network from such situations. 
 
 

 
When network is under heavy traffic, the shared memory buffer in the switching devices might yield 
incorrect detections due to overfed memory buffer. This setback can happen either when data is 
transmitted in IEEE802.3x Full Duplex or Back Pressure Flow Control mode. To solve this problem, 
Live-GSH5T utilizes a fixed memory buffer allocation with Store-and-forward transmission to 
ensure an effective buffer allocation for each port. 
 
Store-and-forward transmission controls data flow from transmitting to receiving nodes with the 
receiving buffer threshold adjusted to an optimal value, thus guaranteeing against all possible packet 
losses. 
 

 
Live-GSH5T Gigabit Ethernet Switch implements in full duplex mode a flow control that is 
compliant to IEEE 802.3x standard.  While in half duplex mode, it employs an optional Back
