Power cords in prox to ethernet & HDMI?

I have an old mid century stereo console (stereo didn't work anymore) and I'm in the process of configuring it to hold electronics in my office. I removed all the old electronics and am working on the layout and configuration. The exterior will remain as-is but the interior will be modified.

There are 3 lower compartments side-by-side. The far left will have a UPS and 8 port ethernet switch, middle is an AVR, PS3 and small PC, last has a small subwoofer.

I want to run all the power cords down and across the bottom to the UPS through holes I'll drill in the partions. The ethernet and HDMI cables will go up, with the CAT 6 cables going across the top into the first compartment, dropping down to the switch that will be attached to the wire shelf on the wall.

My question is; will there be any negative effects of having the network switch and ethernet cables so close to the UPS/power center?

 

Years ago, the rule was to not run power cables parallel to any kind of signal cable, including speaker cables. A small electric field around the power cable could cause signal degredation in the signal cable. This is probably less likely today if you use quality cables with good shielding. Still wouldn't hurt to avoid parallel runs.

Having Ethernet cables and switch near the power center would probably not be an issue, but again, wouldn't hurt to keep em apart where possible.

 

It'll be fine. They both use pretty noise resistant protocols. But if you see anything funny in your TV picture, that would be a good place to start looking.
