1. A method, comprising:
obtaining, in a warm backup state, a first parameter in response to a trigger condition, wherein the first parameter includes a startup parameter that instructs a transceiver of a communications device to be started from a low-power power-off state, wherein the startup parameter comprises at least one of a gain of an amplifier in the transceiver or a filtering parameter in the transceiver, wherein the warm backup state indicates that the communications device is in a power-on state and the transceiver is in the low-power power-off state before occurrence of the trigger condition, wherein the low-power power-off state indicates that the transceiver cannot receive and transmit network traffic, wherein the trigger condition indicates that an active switchover or a standby switchover is to be performed between a second communications device that is faulty and the communications device, wherein the second communications device is an active device and the communications device is a backup device, and wherein the first parameter indicates that the transceiver is to run based on the startup parameter; and
instructing the transceiver to be powered on using the first parameter to cause the communications device to exit the warm backup state.
