The ComNet CN1IPSbt-DC is an industrial grade / environmentally hardened PoE injector that complies with the PoE standard as defined by the IEEE 802.3bt Type 4 while maintaining backward compatibility with the previous standards as defined by IEEE802.3at-2009 and IEEE802.3af-2003. The media converter consists of one 10/100/1000/2.5G/5G/10GBASE-T(X) RJ-45 Ethernet port and one auto-negotiating 10/100/1000/2.5G/5G/10GBASE-T(X) RJ-45 PSE port. When supplied with an operating power input of 52 to 56 VDC, PoE that is compliant with the PoE standard as defined by IEEE 802.3bt Type 4 is injected, capable of delivering up to 90W of PoE to a compliant powered device (PD). CN1IPSbt-DC is designed to allow for optional redundant operating power inputs.
