The subject matter herein generally relates to a server.
In a server system, when a motherboard of a server needs to be repaired, a side of an enclosure of the server is detached to gain access to the motherboard. However, if the user forgets to power off the server when repairing the motherboard, he/she may be electrocuted or short-circuits to circuitries on the motherboard may occur.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The present disclosure relates to a server.
The electronic switch 43 can comprise a first terminal, a second terminal, and a third terminal. The first terminal of the electronic switch 43 is electrically coupled to the pin 1 of the connector 41, the second terminal of the electronic switch 43 is electrically coupled to the indicating unit 49 and electrically coupled to the power supply P3V3_BAT through a resistor R2, and the third terminal of the electronic switch 43 is electrically coupled to the ground. In at least one embodiment, the electronic switch 43 can be an n-channel metal-oxide semiconductor field-effect transistor (NMOSFET), and the first terminal, the second terminal, and the third terminal of the electronic switch 43 correspond to a gate, a drain, and a source of the NMOSFET. In other embodiments, the electronic switch 43 can be an npn-type bipolar junction transistor or other suitable switch having similar functions.
The switch unit 47 can comprise a buffer U1, a switch chip U2 and a jumper J1. The buffer U1 can comprise a detection pin SENSE, a delay pin CT, an input pin
The indicating unit 49 can comprise a buffer U3, at least two light-emitting diodes LED1 and LEDN, and at least two resistors R5 and RN. The buffer U3 can comprise at least two enable pins
In at least one embodiment, the control unit 45 can comprise an Integrated Baseboard Management Controller (IBMC) 453. The input pins A1 and AN of the buffer U3 are electrically coupled to the IBMC 453.
In at least one embodiment, in event that the power-on pin 50 of the server 100 receives a high level signal, such as logic 1, the server 100 is powered off. In event that the power-on pin 50 of the server 100 receives a low level signal, such as logic 0, the server 100 is powered on.
When the server 100 needs to be repaired, the cover 13 of the server 100 is detached from the base 11, and the first terminal 21 of the switch 20 is disconnected from the second terminal 23 of the switch 20. The pin 1 of the connector 41 outputs a high level signal to the first terminal of the electronic switch 43 and the input pin
When the cover 13 is detached from the base 11 and the server 100 does not need to be powered off, the pin 3 of the jumper J1 is electrically coupled to the pin 4 of the jumper J1. The pin 4 of the jumper J1 outputs a high level signal to the enable pin
The first terminal of the electronic switch 43 receives the high level signal output by the pin 1 of the connector 41, and the electronic switch 43 is turned on. Each of the enable pins
After the server 100 is repaired, the cover 13 covers the base 11. The first terminal 21 of the switch 20 is electrically coupled to the second terminal 23 of the switch 20 through the third terminal 25 of the switch 20. The pin 1 of the connector 41 is electrically coupled to the ground through the switch 20. The pin 1 of the connector 41 outputs a low level signal to the first terminal of the electronic switch 43 and the input pin
The first terminal of the electronic switch 43 receives the low level signal output by the pin 1 of the connector 41, and the electronic switch 43 is turned off. Each of the enable pins
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
