Impressive switches! Looking forward to new hw offload capabilities for data center use. Hopefully RAM can be configured for traffic buffering..

Really wish the poe switch was multi-gig

- LtAP mini LTE kit (2024)

I hope at some point in time there will be 5G variants of devices like that.
(aside from only the Chateau 5G)

Will there be -48VDC power supplies for the CRS520? Any MPLS HW acceleration possible in the future? Stacking? Faster-than-light communication? Ok maybe that one is too big an ask.

@pe1chl
Yeah, and a couple of outdoor units wouldn't hurt. One with a directional antenna for rural areas and one omnidirectional for urban areas.

When netPower 8P8B come out?
CRS320-8P-8B-4S+OUT

Any + or -, 24V or 48V power source for CRS320-8P-8B-4S+RM ???
Only 230V? Internally no jack for 24 or 48???

Yes netpower 8P8B would be nice but please don't forget the 24V passive option (even for just the first 8 ports that are not 802.3bt).
Current netpower 16P can't power a SIKLU EH-1200F microwave link (specified as 802.3at), actually it seems a borderline case as no overload messages are logged but the radio keeps rebooting, so the overload is probably by a small margin. It worked fine with the PoE power supply from Mimosa A5, and Mimosa A5 also worked fine from CRS328-24P.
The warnings about ground loops etc. may suggest the power supply has positive ground, or possibly floating.
Perhaps external -48V DC could be hacked by using the hot-swap PSU connector instead of inserting the PSU itself.
Older CRS328-24P had negative ground for both +24V and +48V PoE.
Fully 802.3af/at/bt standard compliant devices are required to have isolated power input so it doesn't matter.
Most of the "compatible" or "passive" PoE devices have negative ground, that's why the external isolated DC/DC converter like RBGPOE-CON-HP is necessary. Some are fully isolated simply by having a plastic antenna case (but beware of USB ports).
PoE is a bit of a mess actually, MT is not the only one who makes it - latest and greatest UI Wave AP Micro has 2.5Gb port but PoE is 48V passive 2-pair or 24V passive 4-pair, and needs to be "forced on" as is not auto-detected by netpower 16P. And it's a new product and quite expensive, so one would hope they wouldn't save $1 on proper 802.3at PD circuits.

Yes, something like the wAP ac LTE or the SXT LTE6 but with 5G capability... We would not need LHG or ATL style equipment, but maybe others do.

And not another SXT with the same poor antenna. The SXT LTE6 upgrade which says “supports B28” is a bit of a joke since the antenna gives crappier performance then none at all for 700Mhz.

Actually I am amazed that it is possible to make an antenna that covers all LTE/5G bands and still has some gain/directivity, without resorting to bulky designs like a dish or a logper.
Those bands go as low as 700 MHz and as high as 4700 MHz!

Knowing that the whole Industry and Wi-Fi is moving to mGig with PoE++, having the CRS320-8P-8B-4S+RM with just 1 Gbps ports is kind of DoA

in real world is not so frecuent to see an AP reaching real 1 gigabit sustained Throughput even when it has multiple radios, most the time high density networks do not use widest channels

off course if you do a speedtest in ideal conditions using the widest channels, that can happen

And there are other (perhaps even more frequent) uses for PoE switches ... and almost none require much more than 10Mbps throughputs (doorbells/doorlocks, HD security cameras, etc.). So why should a budget vendor, such as MT, forget about a mass market of (up-to) Gbps PoE switches?
Hell, I'm expecting that MT's claims about support for 802.3bt would turn out as "actually solid support" for 802.3at (none of MT's devices declared to support 802.3at actually fully support it, they lack some detail or another ... they rather solidly support 802.3af).

Also for APs, in typical home environment (I'm willing to bet that there are more residential APs than business APs out there) there's rarely reallistic need for more than 1Gbps of throughput per wireless device (and since most of users don't require such bandwidths continously this means that same 1Gbps bandwidth can be shared by a few users without noticable congestions). Additionally, ax and newer mostly offers advantage over ac when radio link between AP and station is great ... which in typical household isn't allways the case ... so "backhaul" (wired ethernet) capacity doesn't have to be as high as wireless peak capacity.

Does the new PoE++ switch also do 24v passive on any of the ports for backwards compatibility with other tik gear?

It has a spec sheet on the website. It never mentions 24V, only 802.3af/at/bt so 48V.
I have never seen any MikroTik equipment that can be configured to provide either 24V or 48V PoE, they probably consider the required circuitry too complex.
(we do have some UBNT switches in operation that can do it)

@pe1chl
Use both of the below switches and they provide both voltages 24v/48v, so they do make them that are dual voltage.
https://mikrotik.com/product/crs112_8p_4s_in (With added second power supply for 48v)
https://mikrotik.com/product/crs328_24p_4s_rm

@cdemers : true, but those two devices can do it due to special powering arrangements (CRS112 has two power inputs with two voltages, CRS328 has a dual-voltage power adapter built in). So none of those devices regulate voltage internally.

The new CRS320 uses single-voltage internal power adapter (see specs for optional second power adapter: https://mikrotik.com/product/g1483_0600wnb ), so only 54V is available.
Further more, description of CRS320-8P-8B says "It supports only fully compliant 802.3 at/af/bt Powered Devices" (and goes on with explicitly enumerating a few MT devices). Which very likely means no support for passive PoE even if PD accepts up to 57V but doesn't state 802.3af/at compliancy.

BTW, I'm pleasantly surprised to see that device fully supports 802.3 standard (or so the specs and support docs indicate; unlike incomplete support for 802.3at by previous devices). That's a new thing for MT ... great!

I think Mikrotik is slowly migrating from passive PoE. Bit by bit we are seeing more 802.3a compliant products.

Yes, of course a "passive PoE" is very simple when there already is a 24V regulator in the device (i.e. it comes with a 24V brick).
57V is doable but requires a bit more careful design and component choice.
But standards-based PoE always was a lot more complicated. With integrated circuits that support it becoming cheaper, it has become an option to use it in low cost devices.
Good to see it, because passive PoE, and especially 24V-only, devices are always a bit of a nightmare.

I never understand why 24V devices exist... Why not 48V which is standard ? It's PITA when you, for eg., have PoE switch and than PTP antennas are 24V...

Because sometimes companies like Mikrotik dont wait until a standard is set through RFC etc and start to use pre-standard setups which later on turns out to be not compatible with the standardized setup.

But now they have a set of legacy equipment they cant get rid of and if really unlucky they will not be able to find PHY's who supports both standards and non-standards at the same time.

So here we are with 24V, 48V, 52V, 54V, passive and active negotiation along with standards and non-standards when it comes to power over ethernet...

I'd agree with you if they didn't *just* release NetMetal ax with 24V passive only support, while NetMetal ac2 (which is now discontinued) *did* support 48V af/at.

Probably because one can use 24V batteries to do power backup of remote wireless sites? It's quite common this use case. Although some new devices have a really small range of working voltages... 12V to 28V doesn't work well neither with 12V batteries nor with 24V ones. This should be 10V to 32V. THEN it would be quite easy to plug on 12 or 24 volts batteries.

24V Passive PoE is far cheaper than 50V+ DC/DC converters and PD-PSE handshakes.

10-32V is very handy voltage range indeed. Covers many battery scenarios.

I wrote it above: because it is easy to implement that when your device is already running off 24V power (powerbrick).
Most MikroTik devices are designed to run off 12-24V power. It is possible to design them to run from 12-57V power, and some devices do allow that, but it requires attention when designing the power regulator, and probably some slightly more expensive parts.

E.g. the hAP ac does allow passive PoE at 57V and it will run from MikroTik PoE devices that can be set to "forced on" and "LLDP off", but it will not run from PoE+ switches. The similar aged wAP and wAP ac (MIPSBE model) however DO work on PoE+.

Wait for RB5009 with all 2.5G LAN ports and 2xSFP+ inputs.

the PoE++ switch can only deliver the stated Voltage, to power "passive PoE" devices, you would need to use converter devices like this: https://mikrotik.com/product/rbgpoe_con_hp

This PoE++ switch is not really backward compatible with our older devices, it's more of a introduction to a new line of products, or to power other brand devices that support these standards

Seriously:

No jack, only what is in the specifications. To comply with standards fully, no such thing is possible. All of the power design is changed and all standards are fully compliant now.

I mean replacing https://mikrotik.com/product/g1483_0600wnb G1483-0600WNB with something that accept 24V or 48V.

I have netPower 16P everywhere with solar panels, and often for licensed 18GHz or 13GHz PoE++ is needed and I can not power it with directly with netPower 16P,
but I'm forced to use separate PoE++ injector.

I hope you understand what I mean.

the whole motherboard is redesigned. power supply is only a small part of what makes PoE possible

In the meantime, WISPs worldwide wait for a vendor to bump existing 48-57V passive POE switches from 1Gbps to 2.5Gbps ports (and more than four of them) to run their Wave and Tachyon gear, and with 40-90W, it would even support their Cambium and Siklu (and others?) PTP links.

The RB5009Pr-outdoor was promising, but the 400mA limit causes Wave gear to reboot. The NP16 is just what the doctor ordered, but bandwidth-limited with 1Gbps ports. The CRS310-8G+ is also nice, but no POE. This new one appears to be "standards only" POE with 1Gbps, so another miss.

Tachyon's switch is nice, but it's just a switch, and only four ports at that. Ubiquiti's is the same way (4 SFP+ and 4 2.5Gbps), is 27V 4-pair (ugh), and is also just a switch. (UI's outdoor routers pale in comparison anyway from a capabilities perspective compared to RouterOS.). Netonix has the power output, but is 1Gbps and also, alas, just a switch.

A version of the NP16 with 8 2.5Gbps ports, or a passive POE version of the CRS310-8G+ (in an outdoor enclosure like the awesome outdoor versions of the 5009 and CRS305), and/or a bigger current limiter on the 5009 (600mA+) with a couple more 2.5Gbps ports, would all literally take off (at least in our world).

I for one welcome the pending death of 24v passive PoE. I hate that none of the hAP line of equipment supports standard PoE that can run off any regular PoE switch, because it means that every conversation I have about deploying them I have to add the disclaimer that they can do PoE, only if you have one of a handful of switches that support them, now almost exclusively from one manufacturer as UBNT has dropped support 24v passive on all new models and only a few remain available that still support 24v passive as of last time I checked.

The ability for a AC2/AC3 or AX2/AX3 device to plug into any standard PoE switch from any manufacturer and just work would eliminate a lot of sales barriers to projects.

when some Performance Insight about AMPERE Hardware platform?

Hmm, still waiting for new CCR hardware for replace the CCR2004 series hardware ( currently no USB port ).
Hopefully "24x1G + 4x10G + 2x USB", is there any chance?

@pe1chl
Yeah, and a couple of outdoor units wouldn't hurt. One with a directional antenna for rural areas and one omnidirectional for urban areas.

That would also be my dream equipment right now. And at least the omnidirectional can not be that hard.. Simply but the Cheatau 5G in an Outdoor proof case.(with POE of course)
I am really waiting for something like this @Mikrotik.
