Abstract
One example of a system includes a DC powered monitoring device and a battery backup power supply. The DC powered monitoring device is to monitor the status of an information technology (IT) enclosure environmental infrastructure. The monitoring device is to receive main DC power and backup DC power. The monitoring device is to operate using the backup DC power in response to a loss of the main DC power. The battery backup power supply is to provide the backup DC power to the monitoring device.
Claims13
A system comprising:
- a direct current (DC) powered monitoring device to monitor the status of an information technology (IT) enclosure environmental infrastructure, the monitoring device receiving main DC power and backup DC power, and the monitoring device to operate using the backup DC power in response to a loss of the main DC power and de-energize AC power or high voltage direct current (HVDC) power input to the IT enclosure in response to detecting a fault;
- and
- a battery backup power supply to provide the backup DC power to the monitoring device.
A system comprising:
- a direct current (DC) powered rack controller to monitor the status of an environmental infrastructure of an information technology (IT) enclosure containing servers and a liquid cooling system for the servers and de-energize AC power to the IT enclosure in response to detecting a leak of liquid from the liquid cooling system, the rack controller receiving main DC power and backup DC power where the main DC power is derived from the AC power, and the rack controller to operate using the backup DC power in response to the AC power being de-energized;
- and
- a battery backup power supply to provide the backup DC power to the rack controller.
A method comprising:
- powering a direct current (DC) powered monitoring device of an information technology (IT) enclosure environmental infrastructure using main DC power derived from alternating current (AC) power;
- monitoring, via the monitoring device, the environmental infrastructure for faults;
- de-energizing the AC power in response to detecting a fault of the environmental infrastructure;
- and
- powering the monitoring device using a battery backup DC power supply in response to the AC power being de-energized.
