Problems solved by technology

However, the displacement of the upper cover a5 of the case in the horizontal direction exerts a force in the horizontal direction on the light touch micro switch a1, while the force direction of the arm lever a11 is in the vertical direction, so when the upper cover a5 of the case is closed, the It will have a fatal impact on the arm a11, and it is very easy to damage the arm a11 of the light touch micro switch a1
Once the arm a11 is damaged, the upper cover a5 of the chassis is closed or the next time the upper cover a5 of the chassis is opened, the server open / close box detection function and alarm function will be invalid, and the server open / close box alarm function will not be achieved

no. 1 example

[0041] Such as figure 2 As shown, the server opening / closing box alarm device in this embodiment includes a tactile micro switch 1 and a pressing member 2 , and the tactile micro switch 1 also includes an arm 11 . The light touch micro switch 1 is installed on the backplane 3 arranged vertically in the server, and the arm lever 11 of the light touch switch 1 is pressed in the horizontal direction, and the pressing member 2 is installed under the chassis cover 4 of the server.

[0042] When the case upper cover 4 is buckled down, there is a distance between the pressing member 2 and the arm lever 11 of the slight touch switch 1, and the two do not touch each other.

[0043] When the case upper cover 4 is closed in place, the pressing member 2 is in contact with the arm lever 11, and the arm lever 11 is pressed, and the light touch switch 1 is pressed and turned on.

[0044]Because server products usually inevitably need to use the backplane 3, the backplane 3 is generally use...

no. 2 example

[0046] This embodiment is based on the first embodiment. Specifically, the micro-tact switch 1 is installed on the backplane 3 by welding, and is electrically connected to the backplane controller of the backplane 3 . The method of welding is not only more firm, but also eliminates the wire connection, saves the material cost of this part of the cable and the connector, and also saves the production and processing cost of installing the part of the cable and the connector.

no. 3 example

[0048] On the basis of the first embodiment, in this embodiment, as image 3 As shown, the micro-tact switch 1 also includes a body 12 and a contact 13 . The body 12 of the micro-tact switch 1 is welded on the backplane 3 and is electrically connected to the backplane controller of the backplane 3 . One end of the arm 11 of the light touch switch 1 is connected to the body 12 , and the other end forms a free end. The contact 13 is installed on the body 12 and is located between the arm 11 and the body 12 .

[0049] Under normal circumstances, the arm lever 11 is not in contact with the contact point 13, and the light touch switch 1 is in an off state. When the arm lever 11 is pushed by the pressing member 2 , it moves toward the body 12 , contacts the contact 13 , and presses against the contact 13 , so that the light touch switch 1 is turned on. When the pressing member 2 leaves the arm lever 11, the external force received by the arm lever 11 disappears, and the arm lever ...

Abstract

The invention discloses a server box opening / closing alarm device, system and method, and relates to the field of server safety, the device comprises a light touch micro switch and an abutting member,the light touch micro switch is installed on a backboard, and the pressing direction of an arm rod of the light touch micro switch is a horizontal direction; The abutting member is mounted below an upper cover of a case of the server; The system comprises a backboard controller, a box opening alarm device and a baseboard management controller (BMC); when an upper cover of a case of a server is closed, the abutting member presses an arm rod, a slight touch switch is switched on, and an input / output end of the backboard controller detects a low level and reports the low level to the BMC; When the upper cover of the case of the server is opened, the abutting member leaves the arm rod, the switch is slightly triggered to be switched off, and the input / output end detects a high level and reports the high level to the BMC; And when the level of the BMC changes, a server box opening / closing alarm is generated. According to the invention, the light touch microswitch is prevented from being damaged by stress in the horizontal direction, the risk of server box opening / closing alarm failure is reduced, and the reliability of server box opening / closing alarm is improved.

Description

technical field [0001] The invention relates to the field of server security, in particular to a server opening / closing box alarm device, system and method. Background technique [0002] The server is one of the core infrastructures of the data center, and users have higher and higher requirements for the security of the server. Security includes hardware, software and many other aspects, among which hardware security is the cornerstone of the entire server security. If the security of the hardware cannot be guaranteed, or even the main components are damaged, the security of the entire server cannot be guaranteed. [0003] One of the important functional characteristics of server security is: when the server is turned on or off, the server system must be able to sense the opening / closing event in a timely manner, and manage the system out of band of the server, that is, the server's BMC (Baseboard Management Controller, The alarm platform in the baseboard management contr...
