This chapter covers upgrades to the PT-9000. You can install a slim-type
CD-ROM drive, attach a customer pole display, customer rear display, or
replace the HDD, memory and CPU.
Before you can perform most of these operations, however, you must first
remove one or both of the protective chassis cover and the I/O port PCI
card.

POS Terminal components and electronic circuit boards can be damaged
by discharges of static electricity. Working on POS Terminals that are still
connected to a power supply can be extremely dangerous. Follow the
guidelines below to avoid damage to your POS Terminal or injury to
yourself.
•
Always disconnect the unit from the power outlet.
•
If available, wear a grounded wrist strap. Alternatively, discharge
any static electricity by touching the bare metal chassis of the unit
case, or the bare metal body of any other grounded appliance.
•
Hold electronic circuit boards by the edges only. Do not touch the
components on the board unless it is necessary to do so. Do not
flex or stress the circuit board.
•
Leave all components inside the static -proof packaging that they
ship with until they are ready for installation.
•
After replacing optional devices, make sure all screws, springs, or
other small parts are in place and are not left loose inside the case.
Metallic parts or metal flakes can cause electrical shorts.
