Description

3Com Baseline 2250 (3c16476a) Networking Switch

HP SuperStack 3 Baseline 48-port 10/100 plus 2-port GbE Switch
(JE730A)

Features & Benefits

Affordable, Unmanaged 10/100 Ethernet Switching with Gigabit Uplinks
The 3Com® Baseline Switch 2250 delivers highly affordable wirespeed Layer 2 switching for small to mid-sized networks that don’t need management capabilities.

The switch includes 48 10/100 switching port and two dual-purpose ports for copper or fiber Gigabit connections. Choose between running high-speed 10/100/1000 for fixed copper network backbones or servers or Gigabit SFPs (Small Form-Factor Plug-in) with 1000BASE-LX or -SX transceiver modules for connections to fiber backbones or servers.

Advanced switching features such as IEEE 802.1p traffic prioritization with two Class-of-Service (CoS) priority queues make sure that real-time applications such as video and audio take priority so they run effectively, and enable the switch to operate in larger network environments.

Auto MDI/MDIX ports identify and adapt to the Ethernet cable type, eliminating the most common cabling errors and simplifying installation. Autosensing ports detect and adjust to the speed of the connected device to optimize network performance. The switch is designed to operate as a free-standing or rack-mounted switch with included mounting kit. The standard 19-inch, one rack-unit-high (1 RU) enclosure optimizes valuable office space. Its sturdy design and construction pays off in high reliability and long service life.

Fixed-configuration design makes the switch easy to install right out of the box

Two built-in 10/100/1000 Gigabit copper ports support high-speed connections for use as uplinks, or connections to servers or other switches

Two Gigabit SFP transceiver slots support multimode shortwave fiber (1000BASE-SX) or multimode longwave fiber (1000BASE-LX) connections; mix and match SFP transceivers for media support flexibility

Non-blocking performance means the switch operates at full wirespeed on all ports, delivering unimpeded access to networked resources

Auto-negotiation accommodates mixed-bandwidth LANs

IEEE 802.1p traffic prioritization allow networks to run real-time multimedia applications more effectively by reserving bandwidth for time-sensitive traffic and enables the switch to operate in larger networks

Auto MDI/MDIX on all ports simplifies installation

Easy-to-read front panel LEDs give at-a-glance status and network information to simplify diagnostics and troubleshooting.

Pre-configured setup makes sure that switches work “right out of the box” with no configuration or management software needed

One Rack Unit (1RU) form factor optimizes rack space
