# TrendNet TEG-S562
Following is documentation for unmanaged switch marked as `TEG-S563/EU H/W: V1.0R`.
Original software is running UART on 57600 baud rate. The software does not allow to
do anything fancy via serial. There is `IP` configuration which can be printed as well.
There might be also some flash upload procedure, but using SPI clamp in-board seems to
be easier method.
The memory chip is `Winbond W25Q16JV` with 16M-bit size.
## What does work
1. 2.5G ports on all advertised speeds.
2. SFP+ communication.
3. Serial, Web UI.
## Known issues
1. LEDs are not initialized properly.
## PCB
Manufacturer information be found [on the product page](https://www.trendnet.com/support/support-detail.asp?prod=105_TEG-S562).

### SW1 GPIO switch?
Not populated but looks like a switch for selecting
GPIO level. Missing resistors in place.
GPIO mapping unknown.
### S2 Reset ciruit
Not populated but looks like a button can be added on `S2` connector,
requires additional `R571` resistor which will pull signal to ground.
GPIO mapping unknown.

## LEDs
Leds are not yet working as in stock firmware. This will be handled later.
Ports 1-4 are amber for 100M/1G links, Green for 2.5G.
Port 5-6 are green for 10G/1G link. Both should flash on activity.

## Power supply
Input power is delivered via barell plug, `12V 1A` adapter was provided.
Board has two supply rails. `0.95` and `3.3` volt.
### `0.95` Core Voltage
Voltage is made by a `APW8713` (U3).
### `3.3` Voltage
Voltage is crated regulated by chip marke as `GoIAT` (U2).
## SFP SPI
There is separate clock and data lines for both SFP modules. MSDA/MSCK 0 and 1 need to be enabled.
SFP1 slot is connected to SPI0. SFP2 slot is connected to SPI1.
