Abstract:
1. A file sharing apparatus that performs file sharing processing, the apparatus comprising: a chassis; a first communication control substrate provided within the chassis, which communicates with a host computer; a second communication control substrate provided within the chassis, which communicates with a storage device; a main control substrate positioned within the chassis and connected to the first communication control substrate and the second communication control substrate, which performs the file sharing processing; a first failure detecting section provided on the first communication control substrate, which detects a failure occurring on the first communication control substrate; a second failure detecting section provided on the second communication control substrate, which detects a failure occurring on the second communication control substrate; a third failure detecting section provided on the main control substrate, which detects a failure occurring on the main control substrate; a failure information storage section provided on the first communication control substrate for storing failure information describing information on a failure detected by the failure information detecting section; a failure information managing section provided on the first communication control substrate for obtaining the failure information from the failure information storage section in a predetermined case; a power supply unit that supplies a predetermined amount of power to each of the substrates; and a switch configured to be operated by a user for supplying backup power to predetermined components at least including the failure information storage section and the failure information managing section, wherein: the main control substrate obtains the failure information from the failure information storage section and transmits it to an apparatus for maintenance in a first case where the main control substrate and the power supply unit are operating normally; the failure information managing section operates based on an inquiry from the apparatus for maintenance and obtains the failure information from the failure information storage section in a second case where the main control substrate is not operating normally and the power supply unit is operating normally; and the failure information managing section operates in response to the supplying backup power by an operation on the switch and obtains the failure information from the failure information storage section in a third case where the main control substrate and the power supply unit are not operating normally.
