Chapter 4  Hardware Installation and 
Upgrade
4.1  Jumpers and Connectors
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 sup-
ply, 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 dis-
assemble the panel PC, you can find more useful information in Appen-
dix B.
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.
