Remote access appliance with backup power system

摘要

A remote access appliance (“appliance”) having a backup power subsystem for powering a digital rack interface pod (“DRIP”) that is interfacing the appliance to a remote device. The backup power subsystem may involve the use of at least one shunt regulator subsystem that is adapted to control backup power to the DRIP in the event the DRIP loses power from a USB port of the remote device while a session is in progress with the remote device. The backup power subsystem automatically applies and regulates the power available to the power pins on the RJ-45 port of the appliance to power the DRIP. In the event the DRIP is unplugged form the RJ-45 port of the appliance while backup power is being drawn by the DRIP, the backup power subsystem virtually immediately removes power being applied to the predetermined pins of the RJ-45 port of the appliance. The backup power sub system further will not make power available to the power pins of the RJ-45 port on the appliance unless predetermined operating conditions are present with the DRIP.

1. A remote access appliance adapted to enable a keyboard, video and mouse session with a remote computing device, and further being adapted to provide back-up power to an Ethernet device in communication with an output port of the appliance, where the Ethernet device is interfacing the appliance to the remote computing device, the appliance comprising:
a back-up power subsystem including:
a powering subsystem associated with a signal line of the output port for supplying a regulated power signal to the signal line of the output port; anda controller for enabling and disabling an output from the powering subsystem when communication with the Ethernet device is interrupted; and the back-up power subsystem further operating to inhibit the application of back-up power to the Ethernet device unless a KVM session was is in progress using the appliance.
