Updating the firmware on the Dell EMC PowerVault ME 4 series is pretty straight forward. If you are downloading the firmware on macOS, there's a small caveat though.
The download is delivered as a ZIP-file and contains a single binary file with the extension .bin. When unpacking this ZIP file through the Finder, the BIN file also gets unpacked. In order to successfully get the BIN file, you need to unpack the file through Terminal:
Download the latest firmware from support.dell.com
Start up Terminal and navigate to the folder where you downloaded the ZIP file containing the firmware.
Unzip the ZIP file using the "unzip" command:unzip GT280R004-01-dellemc.bin
Barracuda NextGen firewalls are managed either by webinterface or by using the FirewallAdmin (used to be: NGAdmin) management application. This is a standalone application consisting of a single executable which can be downloaded and run (like a portable app).

Ever since Windows 2000, by default, Numlock is turned off at the logon screen. This can be annoying if you use the numpad to type in (part of) your password. Luckily, you can change this behaviour through a registry fix.
The registry key to change is the same for all versions of Windows, but the value to enter is different depending on the version of Windows.
Fire up regedit.
Navigate to the key HKEY_USERS\.DEFAULT\Control Panel\Keyboard.
Look for the registry value InitialKeyboardIndicators, which needs to be changed to:Windows 7: set the value to 2
Windows 8, 8.1, 10 (older builds): set the value to 80000002
Windows 10 (newer builds): set the value to 2147483650
