Server hard disk indicator light control system and control method thereof

Abstract

The invention provides a server hard disk indicator light control system and a control method thereof. The server hard disk indicator light control system comprises a main board, a back board, a harddisk unit and a hard disk indicator light unit. The main board comprises a programmable logic unit. The backboard comprises an expansion card unit. The hard disk indicating lamp unit is connected withthe expansion card unit and is controlled by the expansion card unit. By means of the design that the expansion card unit can directly receive the first lighting information and the second lighting information transmitted by the programmable logic unit, the expansion card unit controls the hard disk indicating lamp unit to emit light according to the received first lighting information and the received second lighting information, and therefore the operation state of the hard disk unit can be known conveniently. Furthermore, the expansion card unit is ingenuous and low in price, so that the cost is effectively saved, the expansion card unit is small in size, the aperture ratio of the back plate can be increased, the expansion card unit can be conveniently arranged on the back plate, complex arrangement design is not needed, and the production benefit is further improved.

Description

technical field [0001] The invention relates to an indicator light control system, in particular to a server hard disk indicator light control system and a control method thereof. Background technique [0002] In recent years, with the widespread application and development of servers, server systems have been constantly being introduced. In the server system, it is often necessary to use a hard disk storage unit with a large storage capacity to meet the needs of the user for the storage of a huge database, network transmission, or other technical service applications and management of the server system. In order to know in real time whether there is any abnormality in the operation of the hard disk storage unit, it is common to use a hard disk status indicator to display the operation status of the hard disk storage unit. Generally speaking, in a server system, the hard disk storage unit is electrically connected to the processing unit on the backplane and electrically con...

Problems solved by technology

However, an additional CPLD needs to be installed on the backplane, which increases the need for component arrangement, and additionally provides power to the CPLD, which increases the production cost. Moreover, the backplane is usually designed in a long and narrow form, but since the CPLD needs to occupy a large area, As a result, the space for the CPLD needs to be reserved on the backplane, which not only increases the difficulty of design, but also reduces the opening ratio of the backplane, which in turn affects the thermal solution of the server system. Practitioners still need to carefully discuss and study improvement solutions
