-When looking at the RX1 GUI, under servers we can see the Locking code for license generation.
+When using the M1 chassis, it should have been installed using the official .ISO, so this is applicable to both RX1 and MKSP installation.
 \\
+\\
+Even though the interface configuration may look okay, there is an issue with the way the interfaces are installed, to remedy this you can run a small script that will recreate all of the configuration files.
+\\
+\\
+The script <color #ed1c24>update_network_devices.sh</color> can be downloaded {{ :update_network_devices.zip |here}}:
+\\
+\\
+To use the script, copy it to a folder that you have rights to use (/mfeng/home) and give the file exectue rights:
+    chmod +x update_network_devices.sh
+\\
+Now run the file using the following command:
+    ./update_network_devices.sh
+\\
+The script will create new ifcfg-ethx files depending on installed hardware (what NIC cards you have installed).
+\\
+\\
+Navigate to /etc/sysconfig/network-scripts and edit ifcfg-eth0 (as sudo)
+    sudo /etc/sysconfig/network-scripts/ifcfg-eth0
+\\
+Now add all of your IP Details.
+\\
+\\
+Alternatively you can configure the interfaces via nmtui or the front panel (might have to reboot to use the front panel)

+===== Interface Script =====

+#!/bin/sh
+# Script to assign names and hardware IDs to ifcfg-net* files as well as turn on
+# consistent NIC naming. This resolves the issue of NIC ports swapping around
+# due to boot-time race conditions. It should be run manually once after upgrade
+# if you have multiple NICs. However it will delete all network configuration
+# and rename NICs to be net0, net1, etc, which is not supported by all software.
