Dear experts,
Researching the subject of using a Cisco 2921 router with an RPS 2300, I came across a table in the 2900 Hardware Installation Guide that I can hardly believe: table 5-3 seems to tell me that in order to back up ONE 2921 with RPS power, I will need an RPS with TWO 750 Watt or TWO 1150 Watt power supplies. When I read this, I couldn't believe what I was reading.
Is it really true that I need to throw at least 1500 Watts of backup power at a router that has a main power supply of approx 300 W?
