Abstract

The invention relates to a firmware activation device and a firmware activation method. According to an exemplary aspect of the present invention, a firmware activation device includes acquiring means for acquiring an activation area selection signal among firmware programs stored in a plurality of memory areas and a valid information signal. Specify the firmware program to be activated, the effective information signal includes information related to the validity of the activation area selection signal; firmware determination means, the firmware determination means is used to determine to be activated based on the activation area selection signal and the effective information signal activated activation firmware; and firmware setting means for setting the activation firmware as executable.

Description

[0001] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2016-053568 filed on March 17, 2016, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present application relates to a firmware activation device and a firmware activation method, and in particular to a firmware activation device and a firmware activation method for controllers and optical transceivers. Background technique [0003] In recent years, with the advancement and diversification of information communication services, optical communication networks are required to have large capacity and flexibility. As a result, optical transceivers used for fiber optic network connections mainly employ hot-swappable optical transceivers so that optical transceivers are added or replaced after system operation begins. [0004] An example of such an optical transceiver is described in Japanese Patent Application Laid-Open No. 20...
