RCHITECTURE
The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data integrity.
With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

PTIONS
With a comprehensive array of LEDs, the switch provides “at a glance” monitoring of network and port status. The switch can be managed over the network with a web browser or Telnet application, or via a direct connection to the console port. The switch includes a built-in network management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an RJ-45 serial port for out-of-band management. A PC may be connected to this port for configuration and monitoring out-of-band via the supplied RJ-45-to-DB-9 serial (RS232) cable.

The switch contains 24 RJ-45 ports that operate at 10 Mbps, or 100 Mbps, half or full duplex. Because these ports support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.
Each of these ports supports auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10, or 100 Mbps) can be selected automatically. If a device connected to one of these ports does not support autonegotiation, the communication mode of that port can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.

The Small Form Factor Pluggable (SFP) transceiver slots are shared with Gigabit

WITCHING
A network switch allows simultaneous transmission of multiple packets via noncrossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume file server), the device experiencing congestion (server, power user, or hub) can be attached directly to a switched port. And, by using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit
Ethernet network to significantly boost bandwidth while using conventional cabling and network cards.

This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.
VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links.

OTES
1.
Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server, or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode.
2.
Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.
3.
As a general rule the length of fiber optic cable for a single switched link should not exceed:
■
■
1000BASE-SX: 550 m (1805 ft) for multimode fiber
1000BASE-LX: 10 km (6.2 miles) for single-mode fiber
■ 1000BASE-LH: 80 km (50 miles) for single-mode fiber
However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment.

An optional Gigabit SFP (1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or
100BASE-FX) 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.
W ARNING :
This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1
Laser Product and are inherently eye safe in normal operation.
However, you should never look directly at a transmit port when it is powered on.
W ARNING :
When selecting a fiber SFP device, considering safety, please make sure that it can function at a temperature that is not less than the recommended maximum operational temperature of the product. You must also use an approved Laser Class 1 SFP transceiver.
1.
Remove and keep the LC port’s rubber plug. When not connected to a fiber cable, the rubber plug should be replaced to protect the optics.
2.
Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.
3.
Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing

When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you 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.
◆ Using your building’s floor plans, draw a map of the location of all networkconnected equipment. For each piece of equipment, identify the devices to which it is connected.
◆ Note the length of each cable and the maximum cable length supported by the switch ports.
◆ For ease of understanding, use a location-based key when assigning prefixes to your cable labeling.
◆ Use sequential numbers for cables that originate from the same equipment.
◆ Differentiate between racks by naming accordingly.
◆ Label each separate piece of equipment.
◆ Display a copy of your equipment map, including keys to all abbreviations at each equipment rack.

I N -B AND A CCESS
You can access the management agent in the switch from anywhere within the attached network using Telnet, a web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled.
If it has not been disabled, then check the network cabling that runs between your remote location and the switch.
