Abstract

The invention provides a method and device for firmware upgrading. The method comprises the steps that when online upgrading of target POE firmware is detected and legality verification of target POE firmware of a new version is passed, the version of the new version of target POE firmware and the software version will be processed by compatibility verification; if the version of the new version of target POE firmware is compatible with the software version, upgrading of the target POE firmware will be allowed; and when the target POE firmware is upgraded, first prompt information will be output, and whether the new version of target POE firmware will be set to the target POE firmware version with default running after restarting will be determined according to a selection instruction which is input in response to the first received prompt information. Through application of the embodiment of the invention, the failure of equipment normal work caused by incompatibility between the upgraded POE firmware version and the software version could be avoided, and covering of the POE firmware upgrading caused by the equipment restarting could be avoided.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a firmware upgrading method and device. Background technique [0002] The MAC (Media Access Control, Media Access Control) chip of a traditional POE (Power over Ethernet, Power over Ethernet) device is separated from the POE daughter board (a pluggable plug-in card integrated with a POE function chip) in hardware. Serial port communication or other methods of connection realize the management of the main CPU (Center Process Unit, central processing unit) to the MCU (Microcontroller Unit, micro control unit) of the POE daughter board, which belongs to the external POE daughter board device. [0003] With the development of hardware, it can support the integration of the MCU of the POE sub-board into the MAC chip, so that the POE sub-board can save the MCU overhead and save a serial port. On the one hand, the cost is saved, and on the other hand, the hardware is more ...
