100BASE-TX, IEEE802.3i 10BASE-T, IEEE 802.3x and IEEE802.3 CSMA/CD Ethernet Standards. The Fast EtheRx Switch may be used in both standard desktop and 19” rack- mount installations (using the mounting brackets provided with the unit). For easy recognition of network status and troubleshooting, the front panel includes a variety of diagnostic LEDs including Power, 100TX Speed Detection, Link, Receive, Transmit, Collision, and Full-Duplex status.

If any of the items are missing or damaged, please contact your Kingston dealer for a replacement. Be sure the items you receive are genuine Kingston Technology products. If the Kingston name and logo are not on the front panel of your unit, it’s not a genuine Kingston product.
The Fast EtheRx switch provides a simple solution to protect your network against broadcast storming by creating segments based on Layer 2 Ethernet information. As a result, each group of stations connected to a seperate segmented port form an isolated Broadcast Domain.
Forward, which minimizes the re-transmission of faulty data packets. This means that the Fast EtheRx Switch can store the incoming frame in an internal buffer and check the packet for errors before sending it out to the destination port. If the frame does contain errors, it will be discarded and then retransmitted.
Full Duplex /Collision LEDs Link /Activity LEDs Power LED The PWR LED indicates the power status of the Fast EtheRx Switch. The LED will light up steady green when the AC power cord is connected to the unit from a power source.
Port 1 & 2 on the switch are associated with this module. If the optional module is used, then port 1 & 2 on the switch can not be used. For more details on the modules and instructions on installing them, please refer to Appendix D - Fiber FX Modules and installation.
Software Installation Software Installation The Fast EtheRx Switch has several advanced features which can be congured from a Windows 95, 98, NT or 2000 workstation using the provided conguration cable. The software utility allows for VLAN, link trunking, broadcast storm control, secure mode trafc ltering and ow control conguration.
5. Highlight the Printer Port (LPT1) and click on the Properties button. 6. Go to the Resources tab and the Input/Output Range should be displayed. This is the value which needs to be selected in the Switch Conguration Utility. KNS3250/R Users Guide - Rev. A00...

• Verify the conguration cable is well connected. • Ensure that the conguration cable is connected directly from the PC to the Switch. If any other devices are connected to the PC’s printer port, please disconnect them before attempting the conguration of the switch.
The aging time can be set between 1 and 510 seconds. • Disable: The Fast EtheRx Switch will retain the learned source MAC addresses for each port. Only dynamically learned addresses will be aged. No explicit (static) entries will be aged out.

For instance, four full duplex 100Mbps links, such as port 1-4, could be grouped into one 800Mbps link for Trunk 1. Trunking is most commonly used between the switch and server or between two switches.

3250/R switches support MAC address based and port based balancing methods. Using these methods, any packet with a trunk destination received by the switch can be forwarded to a proper trunk port. After choosing one method, the user must specify the relative load-balancing mapping to complete the conguration of the trunk port load balancing.

The group count is not limited. Users can specify n VLAN groups or even more groups for any n (n=number of ports on your switch) port switch. But note that after writing to the device, only the information of the rst n/2 added VLAN groups can be read back from the device of n port switch.
Kingston Switch Configuration Utility Explicit Address Table Page The address table of the switch uses address learning (dynamic) or manual entry (static). Static entries are added to the address table of the device in this window. Static address entries are not aged or updated by the switch’s address learning.

Here we give an example to show how to assign trunks and set VLAN groups. From the gure above, the user plans to congure a 24 port switch into two VLAN groups, one for Engineering and the other for Sales/Marketing. There are four stations connected to Port 5 to Port 8 respectively used by engineers, and a server shared by them which is connected to Trunk 1 by using four trunk ports.
