We have an APC 7500 RT XL UPS, which is 208V, and a Tripp Lite PDUNV attached to it via L6-20P cable. We then have a Cisco 4500 that is plugged into the PDUNV using the C19 ports on the PDUNV. We have a second PDUNV for redundancy. The 4500 powers on and works properly. It is rated 100-240 VAC.
So here is the problem. The PDUNV has several C13 outlets. I have a Cisco 2960 switch, ASA 5520, and 5508 wireless controller that all have power supplies that are rated 100-240 VAC. I tried taking a C13 to C14 power cable and plugging the C13 into one of the PDUNV C13s and then the C14 into the device. None of the devices show any sign of power.
Am I missing something here. Is this not possible?
