Catalyst Family Inline-Power Patch Panel works with any Cisco 10/100 Mbps switching product capable of supporting IP telephones. The inline-power patch panel eliminates the need for external power sources; it is a standalone chassis that can be co-located with the Catalyst switch to provide -48 VDC power directly to the telephone through existing Catalyst family 10/100BASE-TX switching modules. When used with an uninterruptible power supply (UPS), the inline-power patch panel can provide power to the telephone even in a power failure. The inline-power patch panel has 48 RJ-45 input ports and 48 RJ-45 output ports. There are two RJ-45 connectors per port for a total of 48 ports.
