Re: 48vDC Output UPS
I should have been more specific(Quite obvious by the responses I have been getting). I am looking for a rack mount rectifier type device for a remote site(Not a Datacenter/Colo) which outputs 48vdc & has an 120vac input. I would like it to be remote monitor-able via snmp(battery charge, running on batteries etc). I am looking for a runtime of about an hour at about 500w load. A built in battery would be great but an external battery would work as well-I would like the whole setup to be no more than 3ru. The purpose this device will serve to allow remote monitoring of power conditions(Advance Power Outage Notification, Power Glitches etc) as well as power the connected devices for a short while in the event of a power glitch(Brown-Out, Power outages up to 30-45 minutes etc).

Re: Broken SSL cert caused by router?
Meraki Access Points are interesting devices. I have found they cause issues with Linux firewalls if the merakis are not configured correctly. Meraki Access Points do content inspections which I have found can cause produce symptoms similar to yours, although I have not experienced what you are describing. Since the MX64W is both an Access Point security gateway, it has some additional content inspection/intelligence for it's security appliance role on top of the functions it performs as an access point, the same functions which are found in Meraki standalone access points as well. I am not sure what the specifics are as I do not use Meraki security appliances but it is worth checking. I have found with Meraki that items in the control panel/dashboard are not always labeled the best so I have found it is usually worth putting in a ticket with them and/or a call to them to see what they think (1-888-490-0918).

Hi, I have a very odd problem. We've recently gotten a 'real' ssl certificate from godaddy to cover our domain (*.domain.com) and have installed it in several places where needed for email (imap/starttls and etc) and web. This works great, seems ok according to various online TLS certificate checkers, and I get the green lock when testing using my own browsers and such. I have a customer however that uses our web mail system now secured with ssl. I myself and many others use it and get the green lock. But, whenever any station at the customer tries using it, they get a broken lock and 'your connection is not private'. The actual error displayed below is 'cert_authority_invalid' and it's Go Daddy Secure Certificate Authority - G2. And it gets worse - whenever I go to the location and use my own laptop, the very one that 'works' when at my office, I ALSO get the error. AND EVEN WORSE - when I connect to my cell phone provided hotspot, the error goes away! As weird as this all sounds, I got it nailed down to one device - they have a Cisco/Meraki MX64W as their internet gateway - and when I remove that device from the chain and go 'straight' out to the internet, suddenly, the certificate problem goes away entirely. How is this possible? Can anyone comment on these devices and tell me what might be going on here? Mike-

I knew that access to change configuration might disappear but, I was not aware that the data plane could be interrupted as well. That is a excellent item for me to investigate further as I have investigated Meraki as a solution in the past. On a side note, those of you in this situation described below-you may want to take a peek at this: https://meraki.cisco.com/support/#policies:gpl .
