3.1 Overview of Hardware Installation and
Upgrading
The Point of Care Terminal consists of a PC-based computer that is
housed in a plastic rear panel and a metal shielding case. Your HDD,
DDR DRAM, power supply, CPU, and so on are all readily accessible
by removing the rear panel and shielding case. Any maintenance or
hardware upgrades can be easily completed after removing the rear
panel and shielding case.
Warning! Do not remove the plastic rear cover until you have
verified that no power is flowing within the panel PC.
Power must be switched off and the power cord must
be unplugged. Every time you service the panel PC,
you should be aware of this.

Care Terminal before you upgrade your system. All procedures are
