RB260GSP can power up by POE on port 1?

Sun Nov 17, 2024 1:21 pm

Hello,

I just bought an RB260GSP Switch. I connect LAN cable with POE from the company router and it does not power up.
(PoE in: Passive PoE, PoE in input Voltage: 11-30 V

The same LAN cable is able to power up my hEX S Router.
(PoE in: 802.3af/at, PoE in input Voltage: 12-57 V)

Is the RB260GSP faulty or incompatible with the POE from the company router, or am I missing something?

In addition, if I power up the switch with the power supply provided, the POE out works for my hEX S but not for a CISCO IP Phone.

Thank you in advance.

Your company switch most likely works as "802.3 af/at" and provides around 48V. Which is pretty much incompatible with RB260GSP PoE-in requirements.

Provided power adapter is almost certainly 24V and RB260GSP only works as "passive PoE". Which is, again, completely incompatible with 802.3 af/at ... most probably required by your Cisco phones.

In short: PoE landscape can be very complicated when one wanders outside of corporate-grade devices (it's not only Mikrotik, some other vendors also use non-802.3 PoE "standards").
