Example embodiments disclosed herein relate to selectively removing or resetting a restriction from a restricted power sourcing network port. A presence of a computing device coupled to one of a plurality of power sourcing network ports off a network device is determined. A power allocation to the power sourcing network port is determined. The computing device is authenticated to determine whether the computing device has permission to receive power from the network device. The power allocation is restricted. The restriction is selectively reset or removed.

Power sourcing network port reset

A memory includes an address bus, address counter, address decoder, comparator, and control circuit. During a data read or write cycle, the address bus receives an external address, the address counter generates an internal address, which the address decoder decodes, and the comparator compares the external address to a value. Based on the relationship between the external address and the value, the comparator enables or disables the data transfer. For example, such a memory can terminate a page-mode read/write cycle by determining when the current external column address is no longer equal to the current internal column address. This allows the system to terminate the cycle after a predetermined number of data transfers by setting the external column address to a value that does not equal the internal column address. Or, the comparator can compare the external or internal address to a predetermined end address, and the memory can terminate the cycle when the external or internal address equals the end address.
