Almost all of the calls that come into our support center are problems with Hardware,
Windows, Networking or other issues not directly related to the POS Software. We have
found over the years that if you adopt and follow some tried and true techniques you
will have minimal problems with your hardware and software. Most of our customers who
have followed these techniques have been running Plexis POS Software for years without
a single failure. What you will read below are recommendations and your decision to
follow them is entirely up to you.

1. DO NOT turn off your computer without exiting Plexis POS completely.
This includes all terminals as well if running on a network
2. DO NOT reset or restart your computer without exiting Plexis POS completely.
This includes all terminals as well if running on a network
3. Put battery Backups (UPS) on EVERY critical piece of hardware.
This includes the Server, ALL workstations, Network Hubs, Etc.
Leaving one computer unprotected can cause adverse effects on
all other computers.
4. Use a WIRED network on ALL computers. Wireless Networks are not
designed for high speed database applications and are not recommended
or supported with this POS Software.
5. If you use the POS system for surfing the Internet and running your
business at the same time you risk the chance of picking up a Worm or
Virus which could damage your POS program and your data.
6. If connected to the Internet, properly configure firewalls or anti-virus
programs so they don't slow your sales system down. These programs tend to
filter every read and write to the hard drive and can slow performance as
much as 75%.
7. Put a Backup Tape Drive, Mirrored Hard Drive or RAID system in your main computer.
8. Use a dedicated File Server. This means a machine that sits in a closet that
NO ONE uses for anything but running the POS Software and backup routines.
9. Turn off Automatic Windows Updates. Automatic Windows Updates can restart
your computer without properly notifying you. If the Plexis POS SQL databases
are open or you are using the system and Windows abruptly restarts the databases
could corrupt preventing further use of the system. From time to time if you wish
to update Windows do it manually under controlled conditions.
