I have a silly question. We have a 2921 with a DC power supply. I would like to add another power supply for redundancy without adding the RPS 2300. Is the RPS 2300 the only option or is there a way to add another power supply internally?

Hi,
RPS is the only option. From datasheet...
Optional External Redundant Power Supply (RPS) |
● The Cisco 2911, 2921, and 2951 allow for power redundancy through the use of an external RPS device, thereby decreasing network downtime and protecting the network from power-supply failures.
● Redundant power on the Cisco 2900 Series is supported through the Cisco RPS 2300 Redundant Power System. You can use the Cisco RPS 2300 to provide redundant power for Cisco 2900 Series ISRs as well as Cisco Catalyst® switches.
● In order to use the Cisco RPS 2300, an external RPS adapter is required (configurable option) to connect the platform to the external RPS.
