1 / 14 page PD671xxx - 8 / 12 / 24-Channel PoE AF and AT DIMM Data Sheet (Non-confidential) DESCRIPTION KEY FE A T URES Microsemi’s™ new and unique family of Power over Ethernet (PoE) modules enable next-generation network devices to share data and power over the same cable. The PD671xxx PoE PSE modules are fit / form compatible with the standard plug-in memory modules used in personal computers (Dual Inline Memory Modules - DIMMs) (see Figure 1 and Figure 12). Thus, the use of these modules permit network devices to be designed for up to 96 ports, with fewer ports actually installed. Additional modules can be inserted in the field at any time. The PD671xxx (8, 12 or 24 ports DIMM) includes a wide range of functions. Some of these modules include the PD69000 micro-controller unit (PoE controller) for Enhanced features and a flexible work environment in a DIMM master or DIMM slave configuration (refer to Ordering Information, page 2). Microsemi’s PoE PD671xxx DIMMs implement real time mechanisms including detection, classification, port real-time protection and system level functions (power management and MIB support). Microsemi’s PD69012 IC, 12-channel PoE Manager IC is at the heart of these modules. PD671xxx DIMMs enable the detection of IEEE802.3at-2009 Type 1 (low power) or Type 2 (high power) Powered Devices (PDs), ensuring safe power feeding and removal over Ethernet ports. The PD69012-based DIMMs detect and disable disconnected ports, using DC or AC disconnection methods. The DIMMs are embedded in multi- port and highly populated Ethernet switches, requiring a minimum of external components. The PD671xxx DIMM is fully backwards compatible with the PD670xx DIMM and can be dropped into existing designs.
