Some links in case I ever need to jail-break a Mikrotik device:

In the past I had these manual scripts to power-cycle a hung RaaspberryPi device:
/interface ethernet poe set ether5 poe-out=off /interface ethernet poe set ether5 poe-out=forced-on
or on one line:
/interface ethernet poe set ether5 poe-out=off; /interface ethernet poe set ether5 poe-out=forced-on
I am going to try this script for the port having a Raspberry Pi on it (note: this requires a 48V power brick for the Mikrotik!) on RouterOS version 6.48.3 (stable):
/interface ethernet set [ find default-name=ether5 ] comment="RaspberryPi" poe-out=\ forced-on power-cycle-ping-address=192.168.124.38 power-cycle-ping-enabled=\ yes power-cycle-ping-timeout=2m
The above has not worked for a long time as per [Wayback] No POE Power Cycle @ hEX POE – MikroTik:
But it might be fixed as of [Wayback] RouterOS version v6.47.3[stable] as per [Wayback] MikroTik Routers and Wireless – Software: 6.47.3 (2020-Sep-01 05:24):
…
*) poe – fixed “power-cycle” functionality on RB960GSP;
…
Similar issues exist on RB760iGS/Hex S, and there the fix requires new hardware in addition to firmware as per [Wayback] POE OUT issue on ether5 rb760igs (no power) – MikroTik
Note that I did disassemble both of these routers for inspection and there are obvious changes to the hardware to correct the PoE problems – most notably a completely different relay, capacitor and some minor circuit design changes.
If it still fails, I might try
[Wayback] No POE Power Cycle @ hEX POE – MikroTik: workaround script
:local ipPing ("x.x.x.x") :local pingip # # pingip below RUNS and sets the variable # to number of successful pings ie 3 means 3 of 45 success # can also use ($pingip > 1) or ($pingip >= 1) both TESTED # ($pingip >= 1) means if only 1 or 0 pings do the IF, not the ELSE # :log info ("ping CHECK script IS RUNNING NOW") # first delay 90 b4 ping test incase this is running at POWER UP :delay 90 :set pingip [/ping $ipPing count=45] :if ($pingip <= 3) do={ :log warning (">95% lost ping LOSS to isp GW IP x.x.x.x via ether5 so DO POE powerCYCLE") /interface ethernet poe set ether5 poe-out=off :delay 12 /interface ethernet poe set ether5 poe-out=auto-on :delay 10 :log warning ("ether5 POE HAS BEEN TURNED BACK ON") :delay 90 /system script run emailPOEresult } else={ :log warning ("PoeCyclePINGcheck ELSE ran so no ping loss detected by script") }

Still need to research this further:
Somewhere around 6.44, when upgrading an existing RouterOS device, this snippet became part of the configuration:
/ip ssh set allow-none-crypto=yes forwarding-enabled=remote
A few remarks:
/ip ssh set allow-none-crypto=no forwarding-enabled=nowhich makes the snippet to disappear (because they are default settings according to [WayBack] Manual:IP/SSH – MikroTik Wiki).
Like usual, the on-line documentation is dense and insufficiently clear, hence my measure.
In the future, I need to decipher these posts (via [WayBack] winbox ssh allow none crypto – Google Search and [WayBack] winbox ssh forwarding enabled remote – Google Search):

By default, the [WayBack] MikroTik RB960PGS hEX PoE comes with a 24V power supply.
Most PoE capable devices cannot be powered by 24V but need 48V. I wrote about this before in the midst of the long post Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection (and a whole bunch of Unifi/Ubiquiti/Ubtn links)
- Mikrotik needs to make up their mind, as they ship a 24V power supply which cannot power any 802.3af/802.3at devices. The 48POW power supply enables 802.3af for the RB960PGS hEX PoE: [WayBack] hEX PoE (RB960PGS) – Need 48V Power Supply – MikroTik
So now I re-mention it in a much smaller post so it easier to find back, and a few links to Power over Ethernet – Wikipedia, where especially these bits are relevant:
- 24VDC 0.5A 100 Mbit/s or 1 Gbit/s
- 24VDC 1.0A 100 Mbit/s or 1 Gbit/s
- 48VDC 1.0A 100 Mbit/s or 1 Gbit/s
- 56VDC 1.0A and 2.0A 1 Gbit/s (used for 45W+ load point to point microwave and millimeter band radios
The 24V is what MikroTik sticks to with their default power supply.

Not sure why, but Winbox 3.17 could not connect to out of the box blank MikroTik equipment at all.
Winbox 3.19 complains every now and than, but usually connects fine.
This was while configuring a bunch of [WayBack] MikroTik Routers and Wireless – Products: CRS305-1G-4S+IN.
