### Networking: Caral Internet Router
|
|
|
|
A [MikroTik `CCR2004-1G-2XS-PCIe`](https://mikrotik.com/product/ccr2004_1g_2xs_pcie#fndtn-downloads) is used for internet access.
|
|
It's a fiber card with build in router, supporting 2x 25Gbit SFP28 cages and 1Gbit RJ45 eth.

[The manual](docs/CCR2004-1G-2XS-PCIe_241138.pdf) states:
|
|
|
|
> This form-factor does come with certain limitations that you should keep in mind.
|
|
> The CCR NIC card needs some time to boot up compared to ASIC-based setups.
|
|
> If the host system is up before the CCR card, it will not appear among the available devices.
|
|
> You should add a PCIe device initialization delay after power-up in the BIOS.
|
|
> Or you will need to re-initialize the PCIe devices from the HOST system.
|
|
|
|
In our case, since networking is reinitialized after the LUKS password promt, this should not be a issue in practice. However, if networking would not be available, contact someone for a physical reboot and wait longer before entering the HDD password.
|
|
|
|
To reload the card's virtual interfaces on a running system:
|
|
|
|
```bash
|
|
echo "1" > /sys/bus/pci/devices/0000\:01\:00.0/remove
|
|
sleep 2
|
|
echo "1" > /sys/bus/pci/rescan
|
|
```
|
|
|
|
To restart the card on a running system:
|
|
|
|
```bash
|
|
echo "1" > /sys/bus/pci/devices/0000\:01\:00.0/reset
|
|
sleep 2m # Wait for reboot
|
|
echo "1" > /sys/bus/pci/rescan
|
|
```

### PCIE Side

### HDD Bay

|
|
Note that the slot in the middle of the SATA bay is not connected due to the mainboard only having 4 SATA plugs.
