    • A switch (100) connected to a network is configured to have one or more components that can be placed in a deep sleep mode. The switch (100) includes a management circuit (150) that is configured to wake up the components in deep sleep mode. The management circuit (150) includes a port (151) that receives packets and a wake-up circuit (152) that determines whether a packet received via the port (151) is a magic packet including a unique ID for the port (151) or the switch (100). If the packet is the magic packet including the unique ID for the port (151) or the switch (100), the wake-up circuit (151) is configured to send a wake-up signal to components in the switch (100) to wake up from the deep sleep mode.
    • 连接到网络的交换机(100)被配置为具有可以被置于深度睡眠模式的一个或多个组件。 开关(100)包括管理电路(150),其被配置为以深睡眠模式唤醒组件。 管理电路(150)包括接收分组的端口(151)和确定经由所述端口(151)接收的分组是否是包括所述端口(151)的唯一ID的魔术分组的唤醒电路(152) 或开关(100)。 如果分组是包括端口(151)或交换机(100)的唯一ID的魔术分组,则唤醒电路(151)被配置为向开关(100)中的组件发送唤醒信号到 从深度睡眠模式唤醒。
