Setting the Hard Drive Password
On Windows 10 Enterprise 2019 LTSC, BitLocker can be used to password-encrypt
the hard drive. There is no pre-installed applications to password-encrypt the hard
drive on Linux.

Disabling the Gigabit Ethernet Port (Linux Only)
To disable the RJ45 gigabit Ethernet port on the front face of the RUGGEDCOM
APE1808 module, do the following:
1. Login or gain root access.
2. Using vim or nano, open the file /etc/network/interfaces.
3. In the file, locate the following line:
auto allow hotplug eth1
iface eth1 inet dhcp
4. Change the line to the following:

Troubleshooting the RUGGEDCOM APE1808
The following describes potential solutions for common problems.
Lost IP Address
The simplest resolution to this problem occurs when the RUGGEDCOM APE1808 is
easily reached and a monitor is attached. The RUGGEDCOM APE1808 can be queried
for the IP address and the configuration of the RUGGEDCOM APE1808 or command
module may be changed to allow networking.
If the RX15xx device is remotely situated, it may be possible to use the TCPDUMP
command to trace IP traffic from the RUGGEDCOM APE1808. If the RUGGEDCOM
APE1808 is networked successfully then one of the captured packets will almost cer-
tainly reveal the source IP address. A badly networked RUGGEDCOM APE1808, at-
tached to an incorrect subnet, may still reveal an IP address.
RUGGEDCOM APE1808 Does Not Boot
If the RUGGEDCOM APE1808 LEDs remain dark after an RX15xx device reboot, the
most likely cause of failure is a module-type mismatch. This occurs when a slot's con-
