  • Patent number: 9541972
    Abstract: A card control unit for controlling a line card includes a detecting section, a collecting section, and an estimating section. The detecting section detects mounting of a module into a mounting port in the communication card equipped with multiple cages that each have a mounting port into which a module is removably mounted. When mounting of a module has been detected, the collecting section collects an environmental temperature around a mounting port into which the module has been mounted, a power consumption and specified temperature of the module, and thermal resistance information of a cage mounted with the module. The estimating section estimates an environmental temperature after activation of the module on the basis of the collected environmental temperature, power consumption, specified temperature, and thermal resistance information before the module of which the mounting has been detected is activated.
