Abstract
A system and method for providing hot-swap status indication in a computer system having redundant power supplies. In one embodiment a system comprises an electrical subsystem that is powered by a first power supply and second power supply. The system further comprises a hot-swap indicator configured to provide a first user indication to indicate whether the first power supply is hot-swappable depending on whether the first power supply is operating at greater than a predetermined power capacity usage, such as fifty percent. The system may also include a second hot-swap indicator for the second power supply.
Claims21
A system comprising:
- an electrical subsystem;
- a first power supply;
- a second power supply, wherein the first and second power supplies are coupled to provide power to the electrical subsystem;
- a first hot-swap indicator configured to provide a first user indication to selectively indicate whether the first power supply is hot-swappable depending on whether the first power supply is operating at greater than a predetermined amount of its power capacity.
A method for operating a system comprising:
- first and second power supplies providing power to the system;
- determining whether the first power supply is operating at greater than a predetermined amount of its power capacity;
- selectively providing a first user indication that the first power supply is hot-swappable depending upon whether the first power supply is operating at greater than the predetermined amount of its power capacity.
