3.1 Introduction
The panel PC consists of a PC-based computer that is housed in a plastic rear panel
and a metal shielding case. You can install a HDD, DRAM, and battery pack 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.
3.2 Installing the 2.5" Hard Disk Drive (HDD)
You can attach one Serial Advanced Technology Attachment (SATA) hard disk drive
to the panel PC's internal controller. The SATA controller supports faster data transfer
and allows the SATA hard drive to exceed 150 MB. The following are instructions for
installation:
1. Detach and remove the metal rear cover.
2. There is a metal brace which holds the HDD to the upper left-hand side of the
metal shielding case. (See Fig. 3.1.)
3. Place the HDD in the metal brace, and tighten the screws.
4. The HDD cable (SATA 7P+1*5P-2.5/SATA(15+7)P) is next to the metal brace.
Connect the HDD cable to the PC board (CN5&CN6). Plug the other end of the
cable into the SATA hard drive.
5. Put the metal rear cover on and tighten the screws.
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.
