The Cisco 7204 does not support a mixture of AC- and DC-input power. The Cisco 7204 provides the following features: - Online insertion and removal (OIR)—Allows you to add, replace, or remove port adapters without interrupting the system or entering any console commands.
- Dual hot-swappable, load-sharing power supplies—Provide system power redundancy; if one power supply or power source fails, the other power supply maintains system power without interruption. Also, when one power supply is powered off and removed from the router, the second power supply immediately takes over the router's power requirements without interrupting normal operation of the router.
- Environmental monitoring and reporting functions—Allow you to maintain normal system operation by resolving adverse environmental conditions before any loss of operation.
- Downloadable software—Allows you to load new images into Flash memory remotely, without having to physically access the Cisco 7204 router, for fast, reliable upgrades.
