  • SERVER SYSTEM FOR MONITORING STATUS OF FANS
    Publication number: 20130162438
    Abstract: An exemplary server system includes an enclosure, a number of server groups, a number of fan rows, and a fan indicator system. The fan indicator system includes a number of fan control boards (FCBs), a baseboard management controller (BMC), and a terminal device. One FCB is connected to one of the fan rows to read rotational speeds of the fans of the corresponding fan row, and encodes the read rotational speeds to indicate positional information of the corresponding fan row and positional information of each fan on the corresponding fan row. The BMC receives and processes the encoded rotational speeds to determine whether the fans work normally. When at least one fan is determined to work abnormally by the BMC, the BMC outputs the encoded rotational speeds of the abnormal fans. The terminal device receives and displays the encoded rotational speeds of the abnormal fans.

  • SERVER SYSTEM AND FAN INDICATION METHOD
    Publication number: 20130147631
    Abstract: A server system includes a number of fan control units, a number of fan rows, a determination module, a control module, and a digital display unit. One fan control unit corresponds to one fan row. Each fan control unit reads a rotating speed of each fan mounted on a corresponding fan row, and encodes the read rotating speed positional information of the corresponding fan row and positional information of the fan on the corresponding fan row. The determination module determines whether the read rotating speed is within a predetermined rotating speed range. If the rotating speed is out of the predetermined rotating speed range, the determination module outputs the code of the one rotating speed to the control module. The control module controls a digital display unit to numerically display the code of the rotating speed.
