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
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.
+1
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.
