Sun Microsystems PCI cryptographiphic accelerator (2002) In computing, a cryptographic accelerator is a co-processor designed specifically to perform computationally intensive cryptographic operations, doing so far more efficiently than the general-purpose CPU.
The free polarity allows PoE to accommodate for crossover cables, patch cables and Auto MDI-X. In mode B, pins 4–5 (pair #1 in both T568A and T568B) form one side of the DC supply and pins 7–8 (pair #4 in both T568A and T568B) provide the return; these are the "spare" pairs in 10BASE-T and 100BASE-TX.
