SWITCH ARCHITECTURE The switch performs a wire-speed, non-blocking switching fabric. This allows wire-speed transport of multiple packets at low latency on all ports simultaneously. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. This switch uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received into a buffer and checked for validity before being forwarded.
DESCRIPTION OF HARDWARE 1000BASE-T PORTS The switch contains 24 1000BASE-T RJ-45 ports. All RJ-45 ports support automatic MDI/MDI-X operation, auto-negotiation and IEEE 802.3x auto-negotiation of flow control, so the optimum data rate and transmission can be selected automatically. SFP TRANSCEIVER SLOTS GS-2328KX supports the Small Form Factor Pluggable (SFP) transceiver slots are shared with RJ-45 port 21 to 24.
PORT AND The GS-2328KX Series switch includes a display panel for SYSTEM STATUS system and port indications that simplify installation and LEDS network troubleshooting. The LEDs, which are located on left hand side of the front panel for easy viewing. Details are shown below and described in the following tables.
can switch between Link/ACT mode and SPEED mode by pressing MODE button. When the switch is on Link/ACT mode, the LED of each port indicates the link or act status. The LED of each port shows the link speed status of the port using different colors when the switch is on SPEED mode. Table 4: Mode Status LED LED Condition Status Lit Green shows all LED of each port are in Link/ACT Green OFF Link/ACT mode. Each LED of the port lit Green when port link is good, and Blinks when any traffic is present.
NETWORK PLANNING INTRODUCTION TO SWITCHING A network switch allows simultaneous transmission of multiple packets, and it can partition a network more efficiently than bridges or routers. Therefore the switch has been recognized as one of the most important devices for today’s networking technology. When performance bottlenecks are caused by congestion at the network access point such as file server, the device can be connected directly to a switched port.

MAKING NETWORK CONNECTIONS CONNECTING NETWORK DEVICES The switch is designed to be connected to 10, 100 or 1000Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers. TWISTED-PAIR DEVICES Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.
Step2. If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”) Otherwise, attach the other end to an available port on the switch. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length. NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem.
FIBER OPTIC SFP DEVICES An optional Gigabit SFP transceiver can be used for a backbone connection between switches, or for connecting to a high-speed server. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends. WARNING: This switch uses lasers to transmit signals over fiber optic cable.
CONNECTIVITY RULES When adding hubs to your network, please note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices. 1000BASE-T CABLE REQUIREMENTS All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected.

CABLE LABELING AND CONNECTION RECORDS When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. This will allow user to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption. To best manage the physical implementations of your network, follow these guidelines: ◆ Clearly label the opposing ends of each cable.
A Basic Troubleshooting Tips TROUBLESHOOTING Most problems are caused by the following situations. Check for these items first when starting your troubleshooting: Connecting to devices that have a fixed fullduplex configuration.
Check the port configuration. A port on your Switch may not be operating as you expect because it has been put into a “blocking” state by Spanning Tree, GVRP (automatic VLANs), or LACP (automatic trunking). (Note that the normal operation of the Spanning Tree, GVRP, and LACP features may put the port in a blocking state.) Or, the port just may have been configured as disabled through software.
POWER AND COOLING PROBLEMS Installation IN-BAND ACCESS If the System indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, the internal power supply may be defective. Verify that all system components have been properly installed.
CABLES TWISTED-PAIR CABLE AND PIN ASSIGNMENTS For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. CAUTION: DO NOT plug a phone jack connector into any RJ-45 port.
4, 5, 7, 8 Not used Not used NOTE: The “+” and “-” signs represent the polarity of the wires that make up each wire pair. STRAIGHTTHROUGH WIRING If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.
1000BASE-T PIN ASSIGNMENTS All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
