Will Power Edge Servers and Cisco Routers Power on when given power?

This post mentioned that servers can be powered on when given power (useful for remote power up by PDU).

Does anyone know if Dell PowerEdge servers have this options (particularly 2950 and 2850s). Also, will Cisco 3825 / 2800 router work this way?

The PE2850 and PE2950 servers do in fact have a BIOS setting to control the power state. Cisco devices have no BIOS level settings to control power and are controlled soley by the state of the power switch.

Since most, if not all Cisco gear has a physical rocker switch, then powering on after a power loss will be automatic anyway.
