3Com 3CRUS2475
A switch that can be all things to all networks
It may be a bit of a mouthful, but the 3CRUS2475's full name, Unified Gigabit Wireless PoE Switch 24, tells you more or less all you need to know about 3Com's latest small-business networking product.
Aimed at companies with five to 250 users, the idea is to provide a unified infrastructure for both wired and wireless networking, starting with a Gigabit Ethernet switch. This comes in a large 1U rackmount casing with 24 auto-sensing 10/100/1,000Mbits/sec UTP ports at the front. Four SFP (small form factor pluggable) slots are also on the front panel which, with suitable SFP modules fitted, allow the switch to be connected to others via a backbone fibre network.
So far, so good, but it's quite expensive for a switch. So in addition, you get support for 802.3af Power over Ethernet (PoE) to power items such as wireless access points and IP phones over the Lan.
Unlike a lot of small-business PoE switches, the 3Com Unified Switch can deliver the full 15.4W of power allowed for by the IEEE standard to all 24 ports simultaneously. So there's no management involved -- just plug in an 802.3af device and it can get as much power as it needs.
