Abstract
A server system and a control method for a read/write indicator light are disclosed, in which a serial general purpose input/output signal is issued when a read/write action occurs, a bit of effective non-zero data is written into a register when the SGPIO signal has a level change, a content of the register is checked out every predetermined period, and a drive signal is outputted to drive the read/write indicator light to blink when the data in every bit of the register is not all non-zero, whereby achieving in a technical efficacy of promoting recognizability of the read/write indicator light.
Claims10
A server system, comprising:
- at least a read/write indicator light;
- at least a hard disk module, generating a serial general purpose input/output (SGPIO) signal when a read/write operation is executed therein;
- and
- an indicator control circuit, comprising:
- a register, having a size of a fixed bits each being set to a zero value at the beginning of every a predetermined period, and being written with a non-zero value to one of the fixed bits when the level of SGPIO signal thereof is changed;
- and
- a control unit, checking each of the fixed bits in the register once every predetermined period, and outputting a drive signal to drive the read/write indicator light to blink when any of the bit value is nonzero.
A control method for a read/write indicator light, comprising steps of:
- issuing a serial general purpose input/output (SGPIO) signal by a hard disk module when a read/write operation is executed in the hard disk module, and receiving an effective non-zero information when the SGPIO signal has a level change occurring;
- subsequently writing the received effective non-zero information into a register, the register having a fixed bits each having an initial value of zero;
- checking out a content of the register once every predetermined period, and outputting a drive signal to drive the read/write indicator light to blink when the content is a value other than all zero for all the fixed bits;
- and
- driving the read/write indicator light to blink by the driving signal.
