Hello Meraki customer,
We recently discovered that the external power adapter MA-PWR-90WAC (Model PA-1900-66C1, Rev. 01) included with some MS120-8LP-HW switches may be susceptible to a grounding issue.
This issue only affects MS120-8LP-HWs powered by the above-specified external power adapter. No other power adapter models are affected.
Cisco Meraki will be proactively replacing all affected external power adapters.
