I just got a RPi 3 B+. I installed Raspbian Strech lite on a SD card using Etcher, but all I get is a solid red light, no green light flashes, no HDMI output, no LAN activity, no LAN connection LED.
Things I connected: USB power supply, SD card, HDMI and LAN cable. The LAN cable is connected to a Switch, I do not see green or yellow lights on either side. No USB Wifi connected.
I put the same SD card into a RPI 1 and it boots, I get LED flashes, I get HDMI output (Terminal), I get LAN activity and connection LED on the switch. I did not reformat the card between taking it out of PI3 into PI1.
How can I get the RPI 3 to boot?

There is a Troubleshooting guide in Issue 60 of the MagPi magazine which you can access for free online. https://www.raspberrypi.org/magpi/issues/60/
The Raspberry Pi Foundation have a Troubleshooting Guide on their website: https://www.raspberrypi.org/learning/tr ... ing-guide/
These forums have a post which contains all the information currently available about getting an RPi to boot: "STICKY: Is your Pi not booting? (The Boot Problems Sticky)" at viewtopic.php?f=28&t=58151
On the basis of what you have described my first suspect would be that the version of Raspbian Stretch lite you have installed may not be the most recent (April 2018)
You could bring it up to date in your working RPi by doing
then shutdown, move the card to the new hardware and try powering on again.

An afterthought: what model of RPi 1? Does it take an SD Card - some early RPi did - or a microSD card? Presumably the latter if you are able to move it between systems...

I downloaded the image today. It should be the newest.
I used a micro SD to SD adapter in the PI 1.

I don't have any insight beyond what is in those Troubleshooting links.
Does your power supply, and associated cable, meet the heavier power demands of the RPi3B+ ?

I already ran 4 Amps through those cables, they should work fine.
From the MagPi the only thing I can imagine is a blown fuse, but I find that unlikely.
If the fuse is blown, does the red power light turn on?
From the schematic the light should be after the fuse:

I held a multimeter to the fuse, it shows 0.2 ohms, but the meter would be faily inaccurate there.

If the PWR LED is on it is very unlikely that the polyfuse is causing your problem. If you want to check, use the multimeter to measure the 5 volt rail on the GPIO header. Do the same for the 3.3 volt one there too.
