Chapter 3 Hardware Installation and
Upgrading
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 remov-
ing 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 C.
3.2 Installing the 2.5" Hard Disk Drive (HDD)
You can attach one enhanced Integrated Device Electronics (IDE) hard
disk drive to the panel PC's internal controller which uses a PCI local-bus
interface. The advanced IDE controller supports faster data transfer and
allows the IDE hard drive to exceed 528 MB. The following are instruc-
tions for installation:
1.
Detach and remove the plastic 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 (1 x 44-pin to 1 x 44-pin) is next to the metal brace.
Connect the HDD cable to the PC board (CN7). Make sure that the
red/blue wire corresponds to Pin 1 on the connector, which is
labeled on the board. Plug the other end of the cable into the IDE
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.
