3.1 Overview
The panel PC consists of a PC-based computer that is housed in a protective plastic
panel divided between the front and back halves. Any maintenance or hardware
upgrades can be completed after removing both of these panels. To access only the
HDD, SDRAM, or CPU, it is only necessary to remove the CPU and heatsink cover
and the HDD bracket..
3.2 Installing the 2.5" Hard Disk Drive (HDD)
It is possible to attach one enhanced SATA hard disk drive to the panel PC's internal
controller which uses a PCI local-bus interface. The advanced SATA controller sup-
ports faster data transfer and allows the SATA hard drive to exceed 528 MB.
The following are instructions for installation:
1. Detach the HDD bracket by unfastening the four screws on the top of the HDD
bracket.
2. Place the HDD inside the HDD bracket and tighten the four screws on both
sides of the HDD bracket.
3. The HDD cable (1 x 44-pin to 1 x 44-pin) is next to the HDD bracket. Connect
the HDD cable to the HDD. Make sure that the red wire corresponds to Pin 1 on
the connector, which is labelled on the board. Plug the other end of the cable
into the HDD, with Pin 1 on the cable corresponding to Pin 1 on the HDD.
4. Put the HDD bracket and the new HDD back into the original position inside the
chassis, and fasten the four screws to fix it.

Warning! Do not remove the plastic covers until verifying that no power is flowing
inside the panel PC. Power must be switched off and the power cord
must be unplugged. Every time that the panel PC is serviced, be aware
of this fact.
