Abstract

The present invention relates to a link failure detection apparatus, and more particularly, to a link in which a failure occurs using an LED and a link failure detection apparatus for detecting a corresponding failure.

Conventional alarm display device only informs whether or not the alarm of the link through the LED. Therefore, in order to identify the failure, the operator has to input debugging equipment separately, which takes a long time and delays the recovery of the failure.

In addition, when additional LEDs are displayed for each link to indicate the type of alarm that has occurred, it takes up a lot of space in electronic equipment, and even if additional LEDs are placed, they do not have any function in most normal operations. There was a problem.

According to the present invention, by displaying an alarm type occurring on a specific link on an LED indicating only whether an alarm occurs per link, an operator can quickly identify and recover from a failure that occurs without additional debugging equipment.

The alarm collecting unit 20 collects alarm occurrence information indicating a failure for each link by monitoring a functional unit of the electronic device to which the alarm collecting unit 20 is applied, in particular, an operation state of a link.

In addition, when a failure occurs, the LEDs 11 to 14 corresponding to the corresponding link are made to emit light with the promised color so that the operator can recover the failure of the corresponding link depending on whether the LEDs 11 to 14 emit light.

When the fault is repaired by the operator and operated in the normal state, the LEDs 11 to 14 that emit light are returned to the original state by receiving a low level control signal.

As described above, the conventional alarm display device only informs whether or not the alarm of the link through the LED. Therefore, in order to identify the failure, the operator has to input a separate debugging equipment, which takes a long time and has a problem in that failure recovery is delayed.

In addition, when additional LEDs are displayed for each link to indicate the type of alarm that has occurred, it takes up a lot of space in electronic equipment, and even if additional LEDs are placed, they do not have any function in most normal operations. There was a problem.

The present invention is to solve the problems as described above, the purpose is to allow the LED assigned per link to indicate the alarm type as well as whether or not the alarm of the link, so that the operator can quickly solve the failure without the input of additional equipment To identify and recover.
