Being new to figuring out UPS needs I have referred to the APC website and used the UPS selector tool. However, having discussed this issue with a data center architect, he said it is always not an easy call. so I want to make sure I calculate it correctly and would greatly appreciate input from others.
We are upgrading our IDF to have
2 WS-C3850-12x-48U with 2 SFp-10 each with PWR-C1-1100WAC
3 WS-C3850-48U each with PWR-C1-1100WAC
1 Dell EMC DD2500
1 Cisco 2951 router
The POE switches may use about 200 watts total of inline power each. We would neveruse all5 full POE.
so calculating:
Calculate Watts need to boot switch | |||
30 | Watt Global Reserve | ||
223 | Watt per switch allows boot sequence | ||
253 | Watt per switch to boot |
Calculate Watts needed for POE | (Total Number Of POE ports X 15.4 Watts (POE) X 1.05 for POE loss) |
