RB912UAG-2HPnD-OUT with miniPCI-e card turn wifi off

RouterOS Wireless Networking
1

I’ve got a Mikrotik RB912UAG-2HPnD-OUT with R11e-2HPnD card installed.
So it’s wlan1 and wlan2 in router configuration.
But at the moment i want to use only wlan1.
And antenna will be connected only with wlan1.

I heard that it’s unsafe to power on device with unplugged antenna (wlan2)
So I want to disable wlan2, what i need to do?
I think that I should disable ‘wlan2’ interface and set TX power to 1-2 dB.
Is that correct? Thanks!

If the card is disabled you dont have to worry anymore. As you said: is unsafe to power on device without antenna.

So my actions are:

  1. Connect antennas to wlan1 and wlan2 cards
  2. Turn on Mikrotik
  3. disable wlan2 interface
  4. Turn off Mikrotik
  5. disconnect antenna from wlan2 card
  6. Turn on Mikrotik with wlan1 antenna connected

Thanks!
