That sort of cash should get you a Ribbon (Sonus) SBC 1000. RRP in £ is around 3k and you know the sorts of discounts anything like this attracts just for asking.

How painful is it going to be to manage macOS in SCCM if I've never done it before? A client is asking for it and the first search I did turned up "PKI" so I almost threw up

Not worth it unless you have another product that ties into it and makes it meaningful.

They wanted to do update management but SCCM doesn't do that without Parallels anyway so I'm probably just gonna suggest enrolling in Intune, won't do poo poo as well but at least they have a list of devices.

I think the preferred Microsoft route these days is to just use JAMF and do the integration with that for SCCM/Intune, they announced a big partnership thing last Ignite.

I have a situation which has upset me and yet I have reached the end of my troubleshooting abilities.

Situation is like this. Hotel network. At 9PM every night the entire network (that I built) goes insane. My main Mikrotik router starts telling me that 5 network (Access Point) cables are being unplugged /losing connection and this happens for 5-10 minutes after which everything goes back online as if nothing happens.

These cables are direct links with PoE to Access Points, so there should be nothing else in the way to cause issues. Still this happens every night at 9PM.

Has anyone seen anything like this before. Any ideas WTF to look at? My instinct is to look for EM interference from something happening at 9PM.

Is it 9PM on the dot every night? If it is exactly that I would think that something is going on with the APs (pulling updates or something like that), if it varies it's probably something someone is doing like turning something off, turning something on, or plugging a vacuum into a UPS.

Yep 9PM on the dot. My APs are set to pull updates at like 3AM in the morning, but also this is knocking my entire network offline, I have security cameras that lose footage for those 5-10 minutes but continue as if nothing happens.

I got kind of weirded out by the whole thing so I pointed a security camera at my network rack. Absolutely no one is loving with the stuff at that time. My current theory is their sprinkler system might be doing it since it triggers around that time.

Ohh I read your initial info wrong; are all of the devices supposedly losing connection POE devices, or do non-POE devices lose connection too?
I assume your router doesn't report losing power/rebooting during this time?

Do the mikrotik routers have POE ports, or is there a POE switch behind it? Are there any logs you can pull about spikes/dips in power?
Is there a UPS that the router is plugged into? If not, it might be beneficial to plug it into one and see if the problem still happens.

Could be something drawing a bunch of juice and that causes whatever is doing POE to not have enough to power everything.

The mikrotik router has 10 Gigabit ports. Only ports 6-10 are losing connection according to the router logs. I need to recheck but i *think* those cables go into the floor and then out to APs (direct burial). So like I said, I turned a video camera at my rack and let it record for a day. Its network cable is right inside the server room and is only 7 feet long but still, it starts cutting out too. Right at 9PM the actual video footage starts skipping and cuts out but the DVR is still recording as per time stamps. At this time, ports 6-10 start reporting disconnections and reconnections within say 10 seconds over and over for about 5-10 minutes. I also have remote access connection to the property and noticed THAT dropped right at the same time. That remote connection is on a Windows 2012 Server wired directly into the router.

So the POE APs are showing disconnections but the entire network is freaking out too, so I think they are part of the same problem.

I have a gigantic APC UPS running the network rack and the PoE injectors (ubiquiti gigabit units). Besides that, I called and confirmed there were no power issues at 9PM the entire week. I bet the APC has power logs somewhere. It's a decent idea to retrieve those and check it but I have no evidence that it is a power issue yet.

[edit] just had a thought, if the APC UPS is not a pure sine wave unit, could this contribute to the problem? I have had simulated sine ups's do WEIRD stuff to equipment before.

The ground below the network rack is an Indian burial ground.

If each router interface is routed and not switched you can rule out spanning tree weirdness.

If your UPS isnít a double-conversion unit then itís not isolated from the mains input.

I have a thing for courageous dongles



Pretty much every UPS made in the last decade is able to transfer within a half-sine disruption which is well within the capacity for a PSU to ride out. We did have a similar issue where the the UPS was doing a self-test where it cut itself off from line power and did a partial discharge on battery to make sure it was still able to supply power at the rated capacity. Maybe its doing that and failing/drooping voltage and there isn't monitoring set up to alert on it?

So we have basic Teams -> PSTN calling working fine. My SBC guy needs to spend a bit more time on call routes, once you force him to slow down and break things down logically then he can probably figure it out.

For what it's worth, if you call the PSTN number of another user in your tenant then it realises and just routes it internally, it doesn't dump out to PSTN to come back in again. There's slightly more delay than we get on a SIP call with the server hosted remotely (e.g. call flow going as SIP from our office to a data centre and then back to our office), presumably because the media processor adds a bit of latency. I expect media bypass will fix this.

Me too. They are using an APC Pro UPS 1500 with the 1500va extra battery. Simulated sine wave. I just bypassed it entirely for the whole rack since that's all I have at my disposal at the moment. I will know by 9PM tonight if it helps.

This could be. I didn't have time to figure that out yet but I do know specifically every piece of equipment in that rack specifically says NO on simulated sine wave consumer type stuff. I don't really care to use the APC if just bypassing it works. Its easy to justify the money spent when I have proof the thing isn't working for their setup.
