Hello,

i just bougth a CRS210-8G-2S+IN.

according to spec sheet https://i.mt.lv/routerboard/files/CRS210-8G-2SplusIN-141211150201.pdf it can be powered on ETH1 by PoE (Passive and IEEE 802.3af/at).
Howeverm when i connect the device on ETH1 to my 802.3af/at PoE switches i can’t power the device.

Is there anything i should consider/change?
Other devices using the same switchport & cable can be powered up to 25W (class 4).

Thank you for your help.

A cross-over cable may be required. Please check the compatibility matrix out.

it is weired…
using old poe injector and same cable the device powers up
if using old dgs-1210-10P and same cable the device powers up
if using newer switches (d-link, netgear) the device doesn’t power up at all


thank you for the link…i’ll check it ^^

i found the cause.

when using CROSSOVER Cable i can power the device successfully by a DGS-1210-10P B Rev and DGS-1100-05PD
