PSX/MS1008 Models with Gigabit Uplink 
providing the 100Mbps bandwidth required for multimedia applications. All RJ45 ports 
support the Auto MDI/MDIX function. 
With the built-in Web-based management functionality, managing and configuring the 
switch is easy. From cabinet management to port-level control and monitoring, you can 
visually configure and manage your network via your Web Browser. Just click your mouse 
instead of typing command strings. The 1008 switch can be managed via Telnet, Console, 
or SNMP Management. 
Ethernet switching technology dramatically boosted the total bandwidth of a network, 
eliminating congestion problems inherent with the carrier sense multiple access with the 
collision detection (CSMA/CD) protocol and greatly reduced unnecessary transmissions. 
This revolutionized networking. First, by allowing two-way, simultaneous transmissions 
over the same port (full-duplex), bandwidth was essentially doubled. Second, by 
reducing the collision domain to a single switch-port, the need for carrier sensing was 
eliminated. Third, by using the store-and-forward technology’s approach of inspecting 
each packet to intercept corrupt or redundant data, switching eliminated unnecessary 
transmissions that slow down network traffic.   
Auto-negotiation regulates the speed and duplex of each port, based on the capability of 
both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node 
without loss of data. Auto-negotiation and flow-control may have to be disabled for some 
networking operations that involve legacy equipment. Disabling the auto-negotiation is 
accomplished by hard setting the speed or duplex mode of a port.
