4.1 Overview of Hardware Installation and
Upgrading
The panel PC consists of a PC-based computer that is housed in a
plastic rear panel and a metal shielding case. Your HDD, SDRAM,
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.
If you are a systems integrator and need to know how to completely
disassemble the panel PC, you can find more useful information in
Appendix C.
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.
