Cisco SG300-28 1U DM L3 Managed Switch 128MB RAM 16MB Flash 28xGbE 2xSFP 1xPSU (AR)

This rackmount switch delivers non-blocking, wirespeed switching for your 10, 100, and 1000Mbps network clients, plus multiple options for connecting to your network backbone. 24 10/100/1000 ports wire up your workstations, while the two mini GBIC ports allow future expansion to alternate transmission media like optical fiber for your backbone. It features WebView monitoring and configuration via your web browser, making it easy to manage the 64 VLANs and up to 8 trunking groups. Or, if you prefer, you can use the integrated console port to configure the switch.

The non-blocking, wire-speed, full-duplex switching 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. Four Quality of Service egress queues per port let you prioritize traffic via 802.1p. The switch provides broadcast storm suppression, has hardware MAC address learning, and supports packet filtering and port security. All ports have automatic MDI/MDI-X crossover detection, so you don't have to worry about the cable type, and polarity detection will even automatically correct wiring errors. 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.
