On the bottom of the Net Metal 5, there are 3 rubber plugs. I unplugged one of them and inserted the network cable through the hole, as simple as that. This works without question, but the hole is big enough that I’m afraid it may affect the weather sealing capability of the device. My question is that should I cut the tip of the plug, so that it will only accommodate the diameter of the cable? Here is the photo.
IMHO and from experience, it is very unlikely that water will enter the device from below, even without the plug in place. Of course it is a very nice extra assurance to have. I would cut just enough for the cable to pass through tightly, and maybe consider using silicone gel if I was paranoid about it. But remember to also apply some silicone over the semi-transparent led monitoring window, since some NetMetal units have had serious problems in the past, with water coming in from this point.
Thanks for the reply. So, my guess was correct. The rubber plug indeed can be cut. I’m doing this is that I am afraid the moisture could enter the device easily and internal parts will get rusty very soon. In my country, moisture is always a problem on electronics.
