Instant On - Wired

I thought to help making a list with any third party vendors we came across and happened to play well with the aruba 1930 switch series.
 
   Today i tried the 0,5m UBUQUITI UC-DAC-SFP+  (H21038018...) and the connection seemed ok.  Leds on both switches are green  and the connection established is 10Gbe

Feel free to include yours as well with brand / part number / length to have alternatives.

Hello, You can also try the original Aruba cables: J9283D Aruba 10G SFP+ to SFP+ 3m DAC cable

Hi
   Yeah right I could start with those  since they are the default ones the manual recommends. Perhaps I should add to the title non standard 10G SFP+ cables though. At least for me wasn t an option at my country's e-shops at that time. Better have back up brands for urgent purchases .

Hello, You can also try the original Aruba cables: J9283D Aruba 10G SFP+ to SFP+ 3m DAC cable

This one works as well: https://www.amazon.ca/gp/product/B0784G66WW

Note that the Aruba 1930 flashes the LED to indicate an unsanctioned cable, but it works just fine.

Well it seems it has to do with cable length too? Today I ve used a 2m (instead of the 0.5m) cable of the same company and gave me an amber led.

Cable is
UBIQUITI NETWORKS UDC-2, UNIFI FIBER OPTIC DIRECT ATTACH COPPER CABLE SFP+ 10GBPS 2M (DAC) and due to it's specs

Connector LC-LC
Fiber Mode 50 / 125 μm
Fiber Type Duplex
Cable Jacket PVC
Cable Standard OM3
Insertion Loss ≤ 0.3 dB
Polish UPC to UPC
Jacket OD 2.0 mm
Wavelength 850 / 1310 nm
Jacket Color Aqua
Repeatability ≤ 0.1 dB
Durability ≤ 0.2 dB (1000 Times Mating)
Return Loss ≤ 50 dB
Operating Temperature -40 to 75° C
(-40 to 167° F)

it is a different one since it uses Fiber (light) as a cable and DAC transceivers.

PS Of course the cable is passive due the <5m length

Weird thing is I tried UBIQUITI NETWORKS UDC-1, UNIFI FIBER OPTIC DIRECT ATTACH COPPER CABLE SFP+ 10GBPS 2M (DAC instead of UDC-2 and no amber led there.
So it is definately has to do with cable length. It seems that up to 1m it gives no amber led light for different branded sfp+ cables I used. 

   Today I also used a 2m Maxlink ML-DACs+2 sfp+ and gave me the blinking amber led again.

This worked for me:

Even though this is not a DAC cable , did you use the sfp+ variant ot the sfp? Along with cat 6 cable?
It would be bette except from the link to mention the naming scheme of the cable / transceiver

Late to the party but i used a 0.5m ubiquiti to connect to a ubiquiti switc and it was all ok (UC-DAC-SFP+) so as it worked i ordered more

I used 2 x 2m versions to connect to hp servers (UDC-2) and they report as unsupported transceiver orange flashing light and i would say that its folded back to 1gb

Hi, does anyone know if Mikrotik DAC cables work with Aruba Instant On 1930 switches?

This is the cable in question: https://mikrotik.com/product/xs_da0001

I intend to connect the switch with a Mellanox NIC.
