Maximum power consumption of 440-48p g2 vs 450-48p g2 Typo?


Userlevel 3
Looking at the spec sheets for x440 g2 and x450 g2 and the sheet lists a max power usage of a 440-48p g2 10ge as 961watts,

a similar equipped x450 is listed as 228 watts.

Can anyone from Extreme verify how the x440 spec sheet is figured? or if one of them is a Typo?

The last one is a POE switch so if you loaded all the ports up with POE devices pulling power you would be pulling that amount of power...

Also there is a nice power consumption section on website for the 450 G2 but not for the 440 G2 .. under specifications section.... The both support the POE Plus at 30 watts per port.. Seems they may have separated out the power usage on the 450 G2 in the chart and just combined it on the 440 data sheets.

right, it is the inconsistency with the 2 spec sheets that is the issue.

Model min heat Min W Max Heat Max watts

Summit X450-G2-48p-GE4 238.8 70.0 778 228

X440-G2-48p-10GE4 196 53 755 (740W PoE) 961

I get what you are saying, just would like it if documentation explained what the items were,

Max on one sheet does is not the same metric as Max on the other.

Just hoping someone with extreme is reading

The X450 requires that you put either the 1100 or the 715 watt power supply inside of it. So that should be the switch max WITHOUT a the Powersupply..

They do read and they will jump in I am sure... I for sure see your point

I've forwarded a link to this thread to someone who I believe can help. We'll see what he comes back with.

Engineering has been asked to review the numbers in the datasheet since there seems to be a discrepancy in what the values listed actually indicate. Product Management should be back to comment.

I wanted to update the discussion here to note that Engineering will be testing and will provide both values for the datasheets eventually. Unfortunately, I do not have an ETA from engineering as to when that will be done.
