Many PCs will already have the necessary cabling and connection needed for the N-GXE-POE-xx-01 PoE NIC. However, for some configurations, the PoE NIC needs an additional power source connection at the ATX port. Transition Networks offers optional cable accessories in case the power source connection is not already available. The N-POE-CBLKIT provides all three cable options and is typically used for pre-sales proof of concept. After evaluation, the specific cable required can be ordered individually.
