Switch Giga Baseline 2848-SFP Plus. 48 puertos 10/100/1000BASE-T y 4 puertos de uso dual para conexiones de cobre Gigabit o ranuras SFP para fibra 1000Base-SX o 1000Base-FX. Auto MDI/MDIX en todos los puertos.

Affordable, Versatile Smart Gigabit Switch
The "smart" 3Com® Baseline Switch 2848-SFP Plus sets new standards among small business Gigabit switches with 48 Gigabit ports and 4 SFP slots. A user-friendly web browser lets even network novices easily set up and maintain a network. Wirespeed, non-blocking Layer 2 throughput and a switching capacity of up to 96 Gbps can handle the most bandwidth-intensive applications. Gigabit ports can be used for connections to high-performance computers, as well as high-demand servers. Class of service (CoS) traffic prioritization makes sure real-time applications run effectively and enables the switch to operate in larger networks.

Any of the available ports can be trunked, or aggregated, to create an ultra-high bandwidth pipe to the network core. Copper and SFP-based fiber connections can be mixed together for versatile operation. VLAN support allows administrators to segment their network and divide available bandwidth, while traffic monitoring helps keep the network running at optimum performance even during busy traffic periods.

A new Cable Diagnostic Tool is available in this switch allowing users to troubleshoot cabling problems via the Switch web-management interface. Using the straight forward menu based web GUI, the switch performs basic connectivity tests on the cables connected to the switch and helps to identify problems quicker.

The switch also promotes "ease of use/plug and play" installation, operating straight out of the box, so it's up and running in minutes. With features like auto MDI/MDIX and autosensing ports, the small business switch eliminates the most common cabling errors and simplifies installation, as well as detecting and adjusting the speed of connected devices to optimize network performance.

Small business configurations can vary, so the 3Com Baseline Switch 2848-SFP Plus is designed to operate as a free-standing or rack-mounted unit included mounting kit. The standard one rack-unit-high (1 RU) enclosure optimizes valuable office space. Sturdy design and construction pays off in high reliability and long service life. Limited Lifetime hardware warranty and advance hardware replacement provide peace of mind long after deployment.

- 48 Gigabit copper ports support high-speed connections for demanding desktop applications, servers, network aggregation, and uplinks to the network core.
- Four dual-purpose ports support Gigabit copper or SFP transceiver slots for multimode shortwave fiber (1000BASE-SX) or multimode longwave fiber (1000BASE-LX) connections the switch has a total of 52 ports.
- A cable diagnostics tool allows the user to troubleshoot cabling problems through the convenience of a menu based Web-management interface.
- Link aggregation combines copper or fiber ports to create up to six ultra-high-speed trunks, with up to eight ports per trunk, substantially increasing bandwidth to the network backbone or other switches.
- VLANs (up to 64) enable administrators to group users based on data or traffic requirements to ensure that traffic flow is directed according to priority business needs.
- An intuitive, web-based user interface allows even network novices to set up and administer the network.
- To help administrators get top functionality and performance out of the switch, an online help system supports them through every configuration step, providing key information about switch functionality and features.
- Non-blocking performance means the switch operates at full wirespeed on all ports, delivering unimpeded access to network resources.
- Auto MDI/MDIX on all ports simplifies installation and reduces cabling errors; auto-negotiation accommodates mixed-bandwidth LANs.
- IEEE 802.1p CoS traffic prioritization enables networks to run real-time multimedia applications more effectively by reserving bandwidth for time-sensitive traffic and allows the switch to operate in larger networks.
- One Rack Unit (1RU) form factor optimizes rack space
