We purchased a bunch of MS225-FP48 boxes for our LAN replacement project, we put one in a rack in an open office and the noise was crazy. See below below for the levels recorded by our Acoustics team;
Noise levels @ 0.5 m from the switch are all follows:
Front – 63.2 dB LAeq(2 minutes).
Back – 67.2 dB LAeq(2 minutes).
Noise levels from building services in open plan offices should be circa 40 dBA
As you can see the MS-225 is producing nearly 70% above acceptable dB for an open plan office.
we had a real bun fight with our Meraki account managers to get this addressed (took over 2 months) and in the end we paid the additional money to get a MS250-FP48 which is perfect.
My advise, if you are investing now and concerned about the noise level then stay away from the MS225-FP and invest in the MS250-FP switches
thanks
