Page 7: Introducing The Baseline Switch
Overview of the Baseline Switch 2226-PWR Plus The 3Com Baseline Switch 2226-PWR Plus is a versa- tile, easy-to-use configurable Switch. It is ideal for users who want the high-speed performance of 10/100 switching with the added functionality of Gigabit links, but do not need sophisticated manage- ment capabilities. -
Page 8: Power Over Ethernet (Poe)
1: I HAPTER NTRODUCING THE Power over Ethernet (PoE) The Switch supports Power over Ethernet (PoE) on all 24 10/100 ports. If you plug in a compatible (IEEE 802.3af compliant) device, the Switch will automati- cally detect and supply power to it. By default, PoE is enabled on all 24 ports. -
