"You can order Cisco 2911, 2921, and 2951 with a power supply that is AC, PoE, or DC. ... These platforms also offer power redundancy with the use of an external RPS device (Cisco RPS 2300). A RPS adapter is needed in order to connect a Cisco 2911, 2921, or 2951 to the external RPS device."
=> So we have ordered CAB-RPS2300 and RPS-ADPTR-2921-51.
Now we have recieved the Cable CAB-RPS2300 with 22-pin connector at one end and 14 pin connector at other end. But on the router adapter RPS-ADPTR-2921-51 and on the RPS2300, there is 22 pin Connectors, why ?!?
Is it a mistake in the Cisco document, do we have to use instead CAB-RPS2300-E ?
Please help, I can find any other document in cisco.com that explain this problem, and our end customer expect soon a solution.
Many thanks in advance for your support, Best Regards, Alexandre
