12. A remote access appliance for facilitating a keyboard, video and mouse (KVM) communications session between a managed device and a user located remotely from the managed device, the appliance comprising:
a housing;
a processor disposed in the housing and adapted to facilitate the communication of keyboard, video and mouse information between the appliance and the managed device;
a rack data unit (RDU) subsystem disposed in the housing and adapted to communicate with a plurality of remotely located sensors and to receive sensor data from the remotely located sensors, without the need to transmit the sensor data over a network, the RDU subsystem including at least one of:
an RDU digital interface port;
an RDU e-link port;
an RDU one-wire port; or
an RDU digital relay; and
an interface for interfacing the appliance to the managed device, the interface including:
a serial interface port;
a universal serial bus (USB) interface port;
a video interface port; and
wherein the RDU subsystem receives inputs from the plurality of remotely located sensors, and wherein the remotely located sensors generate signals indicative of at least one of:
a condition of an environment in which the managed device is located; and
an operational state of the managed device.
13. The appliance of claim 12 , further comprising at least one autosensing power supply adapted to sense when a loss of power to a rack interface pod coupled to the appliance occurs, where the rack interface pod is interfacing the appliance to the managed device, and to automatically apply direct current (DC) power to the rack interface pod to maintain the rack interface pod in a powered on condition.
14. The appliance of claim 12 , wherein the interface includes a plurality of autosensing ports adapted to automatically sense whether an external managed device coupled thereto is a serial device or an Ethernet device.
15. The appliance of claim 12 , wherein the appliance is adapted to receive information from a service processor port of the managed device, and to send information to the service processor port of the managed device.
16. The appliance of claim 12 , wherein the interface includes at least one of an RS-232C interface port and an RS-485 interface port.
17. A method for enabling communications between a managed device and a user located remotely from the managed device, the method comprising: using an appliance having a housing to house a processor, the processor adapted to facilitate the communication of keyboard, video and mouse (KVM) information between the appliance and the managed device to implement a KVM session;
using the appliance to house a rack data unit (RDU) subsystem to manage communications with, and to receive sensor data directly from, at least one remotely located sensor located in a predetermined area or at the managed device, without the need to transmit the sensor data over a network; and interfacing the appliance to the managed device by using at least one of the following:
a serial interface port;
a universal serial bus (USB) interface port;
a video interface port; and
a plurality of RDU input ports for receiving inputs from a plurality of remote sensors operatively associated with operation or monitoring of the managed device.
18. The method of claim 17 , further comprising having the appliance automatically sense whether the managed device is a serial device or an Ethernet device.
19. The method of claim 17 , further comprising having the appliance apply backup power to an Ethernet device in communication with the appliance.
