### SWTG024AS
SWTG024AS has at least 4 variants that look the same.
Variants are `managed` and a` unmanaged` version.
Variants are `managed` and a `unmanaged` version.
But both have pcb version `v1.0` and `v2.0`.
Also the RJ45 connects can be all plastic or metal shielding.
Also the RJ45 connectors can be all plastic/non-shielded or with metal shielding.

# SWTG024AS-v2.0 managed vs unmanged

* R95: Installed (SFP2 signal RX-LOS), mean that the manage version can use RX-LOS function.
* R270: Installed (SFP1 signal RX-LOS)
* R268: Installed (SFP2 signal TX_DISABLE, but R262 200R pull-down is to high to drive by the SOC, needs mod!)
* U5: Flash is only 512kB instead of 2/4 MBit.
### Notes
* `TX Disable`-SFP2 and Button `K1` share the same GPIO pin via `R105` and `R85`.
