Abstract
A networking device includes communication interfaces, a System-on-Chip (SoC), and pseudo-sleep mode logic. The SoC includes a processor, a memory, an internal PHY module, and other internal SoC modules. The pseudo-sleep mode logic is configured to detect receipt of a sleep command and, in response, cause the networking device to enter a pseudo-sleep mode in which the internal SoC modules are powered off, except for the internal PHY module, the processor, and the memory, which remain powered on. The logic is also configured to detect receipt of a wake command while the networking device is in the pseudo-sleep mode and, in response, cause the networking device to exit the pseudo-sleep mode.
