Moving the server

This should serve as a manual on moving the server to a new location, should it be necessary. First, let’s go over the minimal requirements the server needs to function:

  • Power: 2 Schuko outlets, preferably on a separate breaker.

  • Space: The server is 723 mm long, 444 mm wide and 87.3 mm high. It needs space in front and back to suck cooling air through. The space should not be dusty. It should be possible to restrict access to the server for data security reasons.

  • Network: The server needs an Ethernet connection (“LAN cable”), preferably CAT7. Be careful to connect the server directly to the router and don’t use a slow switch in between (e.g. the popular 10/100 switches).

  • Internet: The server needs an Internet connection. The minimum upload rate should be 20 Mbit/s. You can check that using speedtest.net. Importantly, the network needs to be reachable from the outside and it should not connect via DS-Lite.

Warning

Before you disconnect the power or network from the server, make sure it is completely shutdown. To shut it down, log into the server and shut it down from, or ask an admin to do so. If that is not possible, you can press the power button (small button on the very left of the front), but do not hold it down! The sever takes a few minutes to turn of completely.

Connecting the cables

1. Setup the UPS (Uninterupted Power Supply):
The UPS, which looks like a black box with serveral power outlets in the back, is a small battery that can provide energy to the server in the event of a power loss, so that the server can shutdown savely. It needs to be connected to a power outlet.
2. Connect power to the server:
The server has two power supplies, which you find in the back. If you look at back of the server, connect the rightmost power supply to the UPS, and the left power supply directly to power, without going through the UPS. This is important so that the server can detect power outages. If possible, you can also connect other appliances the server might need, such as the router or a switch, to the UPS in the leftover outlets. Please don‘t connect power hungry devices (other than the server).
3. Connect the network:
Connect the network cable from the router (if you know it, use a Gbit port at the router), to the leftmost port on the server (looking at the back). This is important, because the server expects the network on the separate network card and not the mainboard.
4. Start the server:
Press the power button, which is the small black button on the very left of the front of the server. The server will start ramping up the fans to full speed to test them. It will take a few minutes until the server started completely. Check the front for any warning lights.

Setting up the network

The network setup is here shown for a Fritz!Box, but they should be generally applicable for other routers as well.

1. Check the Internet connection:
Check if there is a Internet connection, that the speed is high enough and that it does not connect via DS-Lite. On the Fritz!Box, this can be done in the “Internet” < “Online-Monitor” section. If it does connect via DS-Lite, contact the Internet provider and ask for a “full Dual Stack” connection. If asked for a reason say you want to use IPv4 to connect from the Internet to the server.
2. Setup local network:
The server and all guests use the 192.168.1.X/24 subnet. The host connects at 192.168.1.1. These IP addresses need to be reserved in the router. The router should also be configured to be at 192.168.178.1, because the server expects that as the gateway. In the Fritz!Box, this can be done in the “Netzwerk” < “Netzwerkeinstellungen” section. Scroll down for the “weitere Einstellungen” dropdown and click the “IPv4-Einstellungen” Button. Setup DHCP in an address range other than 192.168.1.X/24, e.g. 192.168.178.20-200. Be aware that changing these settings may also change the IP addresses of printers or NAS in the same network.
3. Setup port forwarding & IPv6 suffixes:
To make the server reachable from the Internet, port forwarding needs to be set up. In the Fritz!Box, this can be done in the “Heimnetz” < “Portfreigabe” section. Click “Gerät für Freigabe hinzufügen”, choose the server (you should recognize it by the IP 192.168.1.1) and then set the interface ID to ::0:0:1:1. Add new port forwarding rule:
  • Name: SSH

    • Application: Other

    • Protocol: TCP

    • Port range: 22 to 22

    • External port: 22

    • Access via IPv4 and IPv6

  • Name: Proxmox Webinterface

    • Application: Other

    • Protocol: TCP

    • Port range: 8006 to 8006

    • External port: 8006

    • Access via IPv4 and IPv6
