9700 calculate power requirements for UPS

[nomadewolf]

Hi,

i'm trying to determine the power requirements for our 9700s and which UPS we need, but i find almost zero information on the subject.
Can anyone give me the gidelines on how to determine exactly what i need so that i don't under/over dimension this?
Each of our switches typically consist of 4x OS9-GNI-P24 boards (Full PoE load), 3x OS9-IPS-0600A power supplys, 1x OS9-GNI-C20L, 1x OS9-XNI-U2 and 2x CMW

Thanks in advance

I knew the newer AOS should show you the used power when you issue
"show cmm/chassis/ni/power"

if in doubt use a power-measurement adapter. But be aware that usage depends of PoE power drawn aso..

Hi,
you can find this information in Boilerplate - search in Business portal for it.
f.e. I find there this:

Maximum Power Consumption per board
OS9800-Chassis & Fans = 80W
OS9800-CMM = 40W
OS9700/OS9702E-Chassis & Fans = 80W
OS9700E/9702E-CMM = 27W
OS9-GNI-U24E = 55W (includes 24 SFP MiniGBIC Transceivers)
OS9-XNI-U2E = 36W
OS9-XNI-U12E = 55W
OS9-GNI-C24E = 51W
The 1000BASE-X transceivers include:
SFP-GIG-SX transceiver = 0.75W
SFP-GIG-LX transceiver = 0.9W
SFP-GIG-LH transceiver = 1.0W
The OS9800/OS9700/OS9600 chassis backplane power consumption is:
Negligible
The PoE IP Shelf (OS9-IP-SHELF) power consumption is: Negligible
The power consumption measurements were taken under fully loaded
conditions.
All power consumption figures include a 10% safety margin.
Each chassis AC-to-DC or DC-to-DC Power Supply outputs 600 watts DC
with an efficiency of 75%.

I had found all that information, but somehow, this part had eluded me:
Each chassis AC-to-DC or DC-to-DC Power Supply outputs 600 watts DC
with an efficiency of 75%.

With that, i think i got my bases covered.
Thanks.
