Looks like the SFP numbers are reversed, since GPIOs were mapped to SFP numbers, the need to be reversed too. This fixes swapped display of SFP stats on the webpage.

# 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.
|
|
4. All LEDs
|
|
|
|
## Known issues
|
|
|
|
None.
|
|
|
|
## PCB
|

### 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.

|
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 marked 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.
