The network cables for the Martian network were moved to the new Netgear switch from the old one which had the broken fan.
The martian machines look happy so far.
Above the new switch we have the GC network switch. The two fans of it were also broken. The fans were replaced.
They are now quiet and I am quite satisfied.
I removed some old equipment from the rack outside the control room and stacked them next to the filing cabinets in the control room. I also mounted the new Netgear switch in the rack.
