24-Port 10/100 + 2-Port Gigabit Switch + 2 MiniGBIC SR224G

High-speed 10/100 Switching with integrated Gigabit and fiber expandability

Product Description
This new Linksys rackmount switch delivers non-blocking, wire speed switching for your 10, and 100 megabit network clients, plus multiple options for connecting to your network backbone. Twenty-four 10/100 ports wire up your workstations, while the integrated 10/100/1000BaseTX port connects to the backbone at Gigabit speeds. And the mini GBIC port allows future expansion to alternate transmission media like optical fiber.
It features non-blocking, wire-speed switching that forwards packets as fast as your network can deliver them. Also included are Address Learning and Aging to prevent data transfer errors and Data Flow Control to help prevent packet collisions. The switch provides broadcast storm suppression, and supports hardware MAC and IP address learning.

All ports have automatic MDI/MDI-X crossover detection, so you don't have to worry about the cable type. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Head-of-line blocking prevention keeps your high-speed clients from bogging down in lower-speed traffic and fast store-and-forward switching prevents damaged packets from being passed on into the network.

No matter how intensive your network demands, the Linksys 24-Port 10/100 + 2-Port Gigabit Switch + 2 miniGBIC has speed, flexibility, and reliability that you can count on.

Highest Bandwidth for Great Performance

NETGEAR’ s GS608 8-port Gigabit Ethernet Switch connects your network with the dual advantages of performance and convenience. As a fast, auto-switching Ethernet connection, the GS608 integrates both Fast Ethernet and Gigabit devices into your network—supporting both Windows and Macintosh platforms at speeds up to 10 times faster than Fast Ethernet. Every port automatically senses the right speed and full/half duplex mode, while dual-color LEDs make it easy to monitor link, speed and activity. Auto Uplink™ technology adjusts for either of the two common kinds of cables; and with its embedded Plug-and-Play technology, you simply turn it on and it works. All this in NETGEAR’s compact signature design, plus a convenient stand for vertical positioning.

Product Description:
The D-Link Web Smart Gigabit Switch (DGS-1224T) blends plug-&-play simplicity with exceptional performance and reliability to create a cost-effective solution for bandwidth-starved workgroups and departments. The DGS-1224T provides a solution for any size business with any size need. It supports 2 Combo fiber SFP uplinks for uplinking to servers, storage, or other switching devices providing superior performance with exceptional value. The DGS-1224T delivers a high performance feature set sufficient to monitor and secure a SMB network efficiently.

Advanced Management Features
The DGS-1224T supports SNMP v1. SNMP is a useful tool in managing and controlling SNMP supported network devices. SNMP enables the Web Smart DGS-1224T to be polled to provide valuable information about the status of the unit and send traps on abnormal events. This sharing of vital management information saves time and money.

The DGS-1224T also supports Spanning Tree, provides protection from unintentional cabling loops forming within a network infrastructure. 802.1D Spanning tree detects and breaks these loops ensuring network uptime.

Advanced Security
The DGS-1224T provides a robust set of security features normally found only in fully managed switching solutions. It is equipped with the D-Link Safeguard Engine to protect the CPU from malicious attack. When frames enter the switch, the D-Link Safeguard Engine detects and blocks broadcast, multicast, and unicast flooding which can overload a CPU and bring network traffic to a halt. In addition, the DGS-1224T also provides support for secure encrypted 802.1x port based user authentication, broadcast storm control, and up to 256 static MAC address entries.

IEEE 802.1Q VLAN Tagging
A VLAN (Virtual LAN) is a collection of computers that are grouped together. VLANs allow the network to be segmented into groups (Departmental, Hierarchical, and Security Groups). 802.1Q is a standard that places a “tag” in a frame identifying which VLAN it belongs to. The advantage of this is that all 802.1Q compliant devices can work seamlessly together to manage VLAN traffic.

802.1p Priority Tagging
Like 802.1Q VLAN tagging, 802.1p places a tag in a frame to indicate the priority of the frame. This differs from port-based QoS in that, in port based QoS, all traffic entering a specific port is prioritized the same way with the same value. In 802.1p, a port can receive frames with varying priority tags and classify them based on these tags. For example, a VoIP phone that supports 802.1p can assign a priority to its VoIP traffic. When it enters the switch, the switch can then prioritize it so that voice traffic is always clear and jitter-free.

Link Aggregation
The DGS-1224T supports static link aggregation. Link aggregation provides a means of “trunking” multiple ports together to function as a single large bandwidth channel. When a high-bandwidth channel is needed to uplink to another switch, link aggregation makes this process simple and hassle-free.

Jumbo Frame Support
Jumbo Frame support is designed to improve network throughput and significantly reduce the CPU utilization of large file transfers (such as multimedia files or large data files) by enabling more efficient larger payloads per packet. The DGS-1224T supports Jumbo Frames up to 10KB in size.

Web Management Utility
The DGS-1224T includes the D-Link Web Smart Management Utility. This utility provides a valuable tool in managing, planning, and troubleshooting network configurations. Managing a DGS-1224T Web Smart switch takes only minutes. With full color graphic pictures, diagrams, and easy to understand navigation menus, using the Web Smart Management Utility is as easy as surfing the Internet. Some of the features include:
Discovery List – Every Smart DGS-1224T comes with auto-discovery software that automatically detects and displays up to 254 D-Link Web Smart switches running on your network along with a list of their MAC addresses.
Monitor List - The DGS-1224T can be monitored for status and trap messages sent to a designated station.
Trap View – When an abnormal event occurs on the switch, traps can be set to notify the system administrator.
Device Setting – The Device Setting feature of the Web Management Utility allows the network administrator to set the IP Address, Subnet Mask, Gateway, Send Trap To Address, System name, password, and Location of the DGS-1224T.

With an easy to use web-based interface and a robust feature set, the DGS-1224T makes a great solution for any growing business.
