PAC Standby LED States
The Standby LED on the PAC indicates that software is loaded on the card, but the card is serving as a redundant
component. When the system first boots up, all installed PACs are booted into standby mode. The system must then be
configured as to which PACs should serve as redundant components (i.e. remain in standby mode) and which should
function as active components.
