We recently installed 2 x MX250 configured for warm spare failover. They are racked in consecutive rack spaces in sound proof MDF. The MDF contains 6 racks so there is quite a bit of noise now, but the MX's were installed before anything else and I don't recall them standing out to me as inordinately loud. I also recall that they POST with the fans on full speed and then throttle down unlike the MX100 which just seems to run at one speed all the time.  ... View more

Really? The MX100 is pretty far from an enterprise class product. I don't know what you qualify as a datacenter but in a city like New York where high speed fiber is ubiquitous we have plenty of branches offices where MX100 in a small wall-mount rack in an equipment closet is not uncommon.    My objections are: a) this appliance generates a tremendous amount of noise relative to competitive products. Considering the spec I expect the MX100 to be in small branches more than I do in an HQ's data center. b) Cisco Meraki does not publish spec on sound like you would expect from Cisco general. ...

First, there are absolutely comparable firewalls that produce less sound. We replaced an SonicWall NSA 3600 with the MX100 and it was noticeably louder in a fully ventilated rack. NSA 3600 is a much more capable device and was running Comprehensive Gateway Security. This is actually what prompted me to post on this thread. Based on my description of the sound Meraki suggested a proactive RMA. The replacement device sounded exactly the same. I have never heard the fans run at a different speed. From the moment it POSTs to normal operation the noise is the same or similar. ... View more

Thank Philip. In your experience, does the MX 100 operate as I described above, i.e. fans spin at same speed during boot up as normal operation?    It's almost inconceivable to me that this device operates this way. I literally don't think I've heard anything this loud for what it is. Very frustrating that nobody at Meraki can provide me with high/low fan noise in dB let alons tell me if the fans operate at one speed of multiple speeds.      ... View more

We just deployed an MX100 in our facility and it strikes me that the fans have run at one speed from the moment it POSTed. Can anyone confirm that this is normal behavior?   I don't recall any other Meraki hardware, or like appliance, behaving this way. I expect the fans to run at full speed during boot, and then throttle down during normal operation. I ran the MX outside of the rack on a cool, flat, surface for 2 hours before installing it into the rack. The fans have only run at one speed the entire time.   We have an MS120-48P in the rack that is practically silent. The MX100 is screaming loud. Thoughts?  ... View more
