Advantech PPC-140, PPC-120 manual Overview of Hardware Installation and Upgrading

4.1Overview of Hardware Installation and Upgrading

The panel PC consists of a PC-based computer that is housed in a plastic rear panel and a 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 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.
