ID: 0300 Title: cisco_fru_power: Trying not to inventorize not plugged in FRUs Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.2.3i8 In the previous version, the check did inventorize all FRUs reported by the device. The devices also send information for slots which have no FRU plugged in. This change tries to ignore all not plugged in slots.
