METHOD AND APPARATUS FOR DETECTING COMPONENT REMOVAL WHILE OPERATING IN A BATTERY BACKUP MODE
First Claim
1. A method to detect component removal while operating in a battery backup mode, comprising the steps of:
- providing a control card comprising a control card memory device, wherein said control card is interconnected to a battery backup unit (“
BBU”
) comprising a processor, event log, a BBU release pin, and one or more batteries;
providing power from said battery backup unit to said control card memory device; and
measuring the current drawn by said control card memory device.

Abstract
A method to detect component removal while operating in a battery backup mode, comprising providing power from a battery backup unit (“BBU”) to a control card memory device, and measuring the current drawn by the control card memory device. If the current drawn by the control card memory device is less than or equals a pre-determined disconnect current, the method determines if a BBU release pin has been asserted. If the BBU release pin has been asserted, the method encodes in an event log a battery backup removal event. If the BBU release pin has not been asserted, the method encodes in the event log a control card removal event.
