2. Description of the Related Art
Deployment and integration of long-distance information become crucial for enterprises as a result of global economy development and wide application of enterprise information. Electronic equipment such as servers that are often used in network environment employ a server-control mode to achieve the objectives of collection and management of data and information, as the server management is known to have characteristics that can satisfy the demands of high security, wide bandwidth, high system performance and system expansion flexibility at low cost for information maintenance.
In conventional server management, a cluster of server modules is disposed in a machine cabinet, each of the plurality of servers requires its own set of independent equipment including a power cable, Ethernet interface, system management interface, power supply interface, keyboard/display/mouse interfaces, and optical fiber exchange interfaces, and so forth, adversely necessitating a great number of cables to be disposed in the cabinet. Such server configuration has many drawbacks that include difficulties in rapidly solving the problems when encountered, and inconveniences in installation and replacement of new servers when needed. Moreover, the individual power supply and switching unit for each server also takes up a lot of space in the cabinet. In light of the above, a so-called blade server has been developed to eliminate and improve on the foregoing drawbacks.
Blade servers are a relatively new technology that provides for a more compact server system. Blade servers are smaller than traditional rack-mounted or upright-standing servers in size, and are different from the rack-mounted servers in particular that the plurality of the independent server are slimmed and integrated into individual blade-type electronic devices that highly integrate Central Processor Units (CPUs), hard drives, memories, network interfaces and control chips. The casings of these blade-type electronic devices, similar to detachable cards of various kinds disposed in a computer mainframe, are inserted side-by-side into the rear board of a blade server, allowing them to share the aforementioned equipment, such as the power supply, fan, mouse, keyboard and display interfaces collectively. The integration and application of these blade-type electronic devices occupy relatively less space than conventional vertical-type or racked-type servers and thus has less connecting circuits, which is an advantage to facilitate management.
In addition, a blade-type interface device capable of integrating interface modules, for example, peripheral component interconnect (PCI) cards, is developed and provided by the inventor of the present invention. Thus, provision of blade-type electronic device has enabled wider application of the blade server integrating the foregoing components, capable of executing and performing multiple applications that bring forth beneficial results of modularized algorithm and simulation.
In a conventional method of assembling a blade-type electronic device, the blade-type casing and the blade body integrating the CPU, memories, network interfaces, control chips, or interface modules are first inserted into a slide rail; then, a handle disposed on one side of the body for facilitating assembly is pushed towards the direction of the blade body to actuate a hooking portion provided at one end of the handle for engaging with an opening or protruding portion disposed on the slide rail, whereby a connector disposed at one end of the blade body is precisely inserted into the connector of a server mainframe.
However, this conventional way of electrical connection turns out to be disadvantageous when in use. For example, when the connector of the blade body is correspondingly inserted into the connector of the server mainframe, the two connectors may already be electrically connected to each other, i.e. the system is in operation, however, a user cannot know for sure if the system is in operation if the user has not executed any system function. If the user unknowingly pulls out the blade-type electronic device when the system is in operation, it may lead to a system crash and even cause serious damage to the system as a result.
Accordingly, needs exist for developing a hot-swappable blade-type electronic device such that a user can be aware of the operational status of the system and safely uses the device accordingly.
In light of the drawbacks above, the primary objective of the present invention is to provide a hot-swappable blade-type electronic device.
Another objective of the present invention is to provide a blade-type electronic device enabling users to identify system operational status and accordingly use the device safely.
In accordance with the above and other objectives, a blade-type electronic device proposed by the present invention comprises: a blade-type body; a handle provided on one side of the blade-type body to assist installation of the blade-type electronic device; a connector disposed on one side of the blade-type body to provide electrical connection; and a switch disposed inside of the blade-type body and electrically connected to the connector to switch on/off electric signals of the blade-type body, the switch being able to be turned on when the handle is in an installed position.
In one preferred embodiment, the blade-type body may include a blade-type casing, an adapter card and an electronic unit, wherein the adapter card may be disposed on one side of the blade-type casing, and the electronic unit may be, for example, disposed in the inside of the blade-type casing and can be electrically connected to the adapter card. The blade-type body may further include a first wedging portion, whereas the handle may include a second wedging portion to engage correspondingly with the first wedging portion when the handle is in the installed position. In addition, the handle may optionally include a hooking portion and an actuator for actuating the switch, whereas the switch may include an electrical connector and a switch actuator, the electrical connector being disposed inside of the blade-type body and the switch actuator is fastened at a position inside the front of the blade-type body that can be physically actuated by the handle when in the installed position.
Compared to prior art techniques, the present invention requires only provision of a controlling switch that is compliant with the existing structure, thereby allowing a user to connect or disconnect the blade-type electronic device without turning off power. Thus, the present invention offers advantages over prior art in that it is hot-swappable to prevent incidents of a computer crash or damages to the system due to user's ignorance. Moreover, the user can be aware of the system operational status such that the user can operate and use the device safely.

Then, as shown in
On the other hand, in pulling out the blade-type electronic device 1, one may pull the handle 13 to release it from the installed position and the second wedging portion 133 disposed at the other end of the handle 13 disengages from the first wedging portion 117 disposed at the front side of the blade-type body 11, such that the actuator 135 of the handle 13 is relieved from pressing the switch actuator 173 of the switch 17, thereby the connector 15 is disconnected from the connector disposed on the rear-board of the mainframe server to end the system operation.
Accordingly, the switch 17 is utilized for controlling on/off electrical signals of the blade-type body 11. In short, the switch 17 is actuated to be in an on state when the handle 13 is in the installed position and in an off state when the handle 13 is released from the installed position.
Compared to prior art techniques, the present invention requires only provision of a control switch that is compliant with the existing structure to control on/off electrical signals of the blade-type electronic device, allowing a user to connect or disconnect the blade-type electronic device without having to turn off power. Thus, the present invention offers advantages over prior art in that it is hot-swappable to prevent incidents of a computer crash or damages to the system due to user's ignorance. Moreover, the user can be properly aware of the system operational status, thereby allowing the user to operate and use the device safely.
It will be understood that the above description of the present invention is susceptible to various modifications, changes, and adaptations, and such similar versions are intended to be comprehended within the meaning and range of equivalents of the appended claims.
