Ethernet Module 168-Pin DIMM

The 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 PD671124 PoE PSE modules are fit / form compatible with the standard plug-in memory modules used in personal computers (Dual Inline Memory Modules - DIMMs). 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 PD671124 (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 The PoE PD671xxx DIMMs implement real time mechanisms including detection, classification, port real-time protection and system level functions (power management and MIB support). The PD69012 IC, 12-channel PoE Manager IC is at the heart of these modules. PD671124 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 multiport and highly populated Ethernet switches, requiring a minimum of external components
