MX75 are utter junk

[jasonm2025]

ridiculous.... on about my 10th return over the last 18 months on all different sites

there is a serious defect in manufacturing on these units

not OK for an enterprise company, especially not over 18 months to not resolve this issue - just keep shipping out this garbage to clients

look for mx75 hardware panic / kernel panic

if your mx 75 even hangs once don't troubleshoot don't anything just insist on a next day RMA

We have a decent amount of these in use, and had only one that had the random lockup issue. A power cycle fixed it every time until it did it again. We haven't had the issue return since the 19.1x train, and we never did a hardware swap. To me, that indicates a firmware bug that they indeed did finally fix.

ok lets see i have an 11th unit hanging right now,    its upgrading now

Update scheduled

Current version: MX 18.211.2

Open source licenses

Upgrading to: MX 19.1.10  -

im looking through my units here, i see lots of mx75 that are 12 months+ old on V18 firmware that have never hung........    any explanation from Meraki then how some units work fine on V18 and some don't? doesn't seem to make sense logically......

From a previous post from Meraki:

"Hi All Just a quick broadcast. If you have any customers with MX75 issues, PLEASE advise them to call into support as there are now the following fixes available: • For panics (frequent reboots) -> 19.1.8 • For lock ups (requires power cycle) -> they need to call in to support and support needs to upgrade them to a special version that upgrades the FPGA (and then the device can be downgraded to whatever firmware after that) TLDR; call support as there are fixes and there is no requirement to RMA the device"

sigh so the only solution for the lockup is to wait and see if it locks up first? which is a pain when installed at a remote location with no hands on

[BHC_RESORTS]

No, that is old news - the 19.1.x train is stable now. It should fix any of the MX75 problems. At least we haven't seen any.

@jasonm2025 I feel your pain.

We purchased some MX75's not long after release for some of our most critical sites.

We've had multiple panics/reboots and have RMA'd 4 units.

The latest recommendation was to upgrade to the 19.1.x train but I hadn't been able to as it hadn't been under stable release. Frustratingly, a 3-5 minute downtime for the site while the MX crashes and reboots is less risky than the possibility of introducing further issues by moving away from the stable release train.

Now that 19.1.x is the stable release, we'll be upgrading very soon and hopefully should see some stability.

That said, whilst frustrating, I'll take a crash/reboot any day over some of the other issues I've been dealing with on some other products from other vendors.

I've run an MX75 since they were released and indeed 18 was never stable.  However I've run 19 since the first beta and apart from some utilisation issues, it's been very solid.

We have had to RMA quite a few of this model over the last 12-18 months, but *touch wood* version 19 has been solid and we've not seen any panic's on this firmware.

[ITSDigital]

We run tens of them, and no lockups. Our 75's are running newer firmware (19.1/19.2), but never saw it on the older 18.x train.
