<P>The HP ProCurve 10/100 Hub 12 M & 24M offer 12 and 24 10/100 autosensing ports respectively, with a built-in bridge for easy connection to any 10BaseT or 100BaseT device. The rack-mountable hubs feature built-in management -- including SNMP, RMON and Extended RMON. This provides all the benefits of HP Proactive Networking, including "find-fix-inform" functionality with automatic cable sensing and a Web-style interface. Comprehensive LED displays show information about hub traffic and the status of each port at a glance. In addition to either 12 or 24 RJ-45 ports, both hubs feature an MDI/MDI-X switch for easy connection to other Hubs & Switches using standard twisted-pair cable. The slim 1.7" (1U) profile is ideal for rack mounting in tight spaces. </P>
