The present invention is directed to remote monitoring and control of various devices that are connected to a network. More specifically, the present invention is directed to a monitoring server providing universal serial bus (USB) connectivity between the monitoring server and devices connected to the monitoring server.
Console servers provide systems administrators and other Information Technology (“IT”) professionals a variety of tools to securely access and manage their resources. Using a console server, a network manager may configure, administer and manage various types of IT equipment in a variety of ways. The types of equipment that can be accessed and administered using a console server include, but are not limited to, servers, networking equipment such as routers, switches, storage networking, telecommunications equipment, such as PBX and voice switches, and other systems with serial interfaces, such as, for example, heating/cooling systems, security systems, and building access systems, uninterruptible power supplies, and medical devices.
Until recently, most equipment included an RS-232 serial port, sometimes called a console, auxiliary or management port, through which the equipment could be operated or administered using a computer, such as a laptop, terminal, or other equipment having a processor which could be used to communicate with and/or control the equipment being managed. Thus, the administrator communicating with the equipment needed to be in the same physical location as the equipment being managed.
Console servers or managers were developed to provide the administrator a way to access the IT equipment remotely from anywhere there is a network or modem connection. The console server is located between the IT device to be communicated and controlled and a network, which may be the Internet. The console server provides for remote management and troubleshooting of the IT device without sending a technician onsite. This reduces travel costs and downtime costs, as well as providing instant access to the IT device, reducing response time when unexpected events that affect the operation of the IT device occur. Some console servers also incorporate modern access so that the IT devices can be administered even if there is a network outage.
Modern console servers typically include a plurality of RJ-45 connection ports, usually arranged in one or more modular assemblies that are inserted into an available bay of a console server. For example, a module may include a number of RJ-45 ports, perhaps 8, 16, 32 or more ports.
Recently, however, serial access to the IT device using serial ports is being phased out in favor of Universal Serial Bus (“USB”) ports, which allow for more rapid information transfer rates and offer other advantages. Since console servers typically only offer RJ-45 serial ports, an adapter must be used to allow communication between the RJ-45 serial port of the console server and the USB serial port of the IT device.
What has been needed, and not previously available, is a console server configured to accept a module that includes one or more USB ports that may be used to connect to equipment that lack a conventional RS-232 serial port or an RJ-45 serial port. Such a console could then be directly connected to the device to be managed using a connector cable having USB connectors on each end, thus eliminating the need for either an adaptor, or a special cable that includes an RJ-45 serial connector at one end for insertion into the console and a USB adaptor for connecting to the device. Such a module could be configured to include a plurality of USB serial ports, or it could be configured to include both USB and RJ-45 serial ports, thus offering increased flexibility. The present invention satisfies these and other needs.
In its most general aspect, the invention includes a console server that includes USB ports for connecting the console server to devices that do not possess RJ-45 serial connection ports. One advantage of such a console server is to eliminate the need for RJ-45 to USB cables or translator modules in those instances where a device to be monitored and/or controlled does not have an RJ-45 serial port.
In another general aspect, the invention includes a console server having a plurality of bays, each bay being configured to receive a communication card, which may be either a USB card or a conventional RJ-45 card. An advantage of such a console server is to provide improved flexibility in IT environments having both older equipments that only have RJ-45 serial connection ports, and new equipment having only USB connection ports.
In still another aspect, the invention includes a console server, comprising: a USB port connectable to a device for providing communication with the device; and a network connection in communication with the USB port, wherein the device may be monitored or controlled through the network connection. In one alternative aspect, an RJ-45 serial port connectable to a device is included. In a further aspect, the console server may comprise a host controller and a hub electrically disposed between the USB port and the network connection.
In yet another aspect, the network connection is an Ethernet connection. In one alternative aspect the network connection is configured for communication over a telephone line. In another alternative aspect, the network connection is a wireless network connection. In yet another alternative aspect, the network connection is a cellular network connection.
In another aspect, the invention includes a console server, comprising: a main circuit board including a processor, a memory in communication with the processor, a communication bus in communication with the processor, and a network interface card in communication with the processor; a USB serial card in communication with the communication bus, the USB serial card in communication with the communication bus, the USB serial card including a host controller and at least one hub, the at least one hub in communication with a USB serial port configured for connection to a device to be monitored and/or controlled; and a network port in communication with the network interface card, the network port configured for connection to a network wherein information related to a device connected to the USB serial port may be transmitted to and received from a user connected to the network.
In an alternative aspect, the network port is in wireless communication with the network. In a further aspect, the console server also includes a dial-up connection port in communication with the processor, the dial up connection port configured to transmit and receive information related to the device connected to the USB serial port. In yet another alternative aspect, the network port is in with a cellular network.

Other features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
As will be described hereinafter in greater detail, the various embodiments of the present invention relate to an apparatus and method for providing USB port connections in a console server for connecting the console server to various devices using a USB cable and connections instead of the legacy RJ-45 or other traditional serial cables and connectors. For purposes of explanation, specific nomenclature is set forth to provide a thorough understanding of the present invention. Description of specific applications and methods are provided only as examples. Various modifications to the embodiments will be readily apparent to those skilled in the art and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Thus the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and steps disclosed herein.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art, that the present invention may be practiced without these specific details. In other instances, well known components or methods have not been described in detail but rather in a block diagram, or a schematic, in order to avoid unnecessarily obscuring the present invention. Further specific numeric references such as “first driver,” may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the “first driver” is different than a “second driver.” Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present invention. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component.
Throughout the description reference will be made to various software programs and hardware components that provide and carryout the features and functions of the various embodiments of the present invention. Software programs may be embedded onto a machine-readable medium. A machine-readable medium includes any mechanism that provides, stores or transmits information in a form readable by a machine, such as, for example, a computer, server or other such device. For example, a machine-readable medium includes read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; digital video disc (DVD); EPROMs; EEPROMs; flash memory; magnetic or optical cards; or any type of media suitable for storing electronic instructions.
Some portions of the detailed descriptions are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. These algorithms may be written in a number of different software programming languages. Also, an algorithm may be implemented with lines of code in software, configured logic gates in software, or a combination of both.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the above discussions, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers, or other such information storage, transmission or display devices.
