PCWS 2015 Setup Guide - 2nd Edition 1-3
What is the PCWS 2015
The System
Operator LED
The PCWS 2015 Operator LED is Green to easily distinguish the unit from the
Workstation 5A, which shares similar casework.
The Operator LED blinks two times per second as the workstation starts-up
and performs the Power On Self Test (POST). After the operating system starts
and loads the PCWS API, the Operator LED turns solid Green.
Power Button
The recessed illuminated power button is located on the lower right of the base.
It is used to power the PCWS 2015 on and off. The illuminated power button is
identified by the international symbol for power on/off.
3-Track Magnetic Card Reader
The low profile 3-Track Mag Card Reader is the same as used in the
Workstation 5A.
Cooling System
The dual-core Celeron and i5 processor selections consume sufficient power to
require active cooling. After conducting extensive thermal simulations, heat
pipe cooling technology was selected for the PCWS 2015.
Heat Pipes combine the principles of thermal conductivity and phase transition
to efficiently manage the transfer of heat between ‘warm’ and ‘cold’ surfaces.
A heat pipe consists of a sealed pipe or tube made of copper, connected to both
the ‘hot’ and ‘cold’ ends. A vacuum pump is used to remove all air from the
empty heat pipe, and then it is filled with a small amount of coolant chosen to
match the operating temperature.
On the PCWS 2015, the ‘warm’ end of the heat pipe is heatsink attached to the
processor and the ‘cold’ end of the heat pipe is located under the power supply
cover. The power supply cover is shaped to form a ‘cooling tunnel.’
The 60mm CPU fan pulls ambient air through the front of the base, across the
heat pipe radiator and power supply, before it exits from the left side of the
workstation base. This is illustrated in Chapter 3.
The CPU fan runs at full speed when you start the workstation, then slow to
about 2500 RPM in about two minutes. The fan continues to run at this speed
as long as the workstation is on. If the CPU fan temperature sensor exceeds
47°C, the CPU fan will increase speed to compensate.
Internal Speakers
The PCWS 2015 introduces Intel High Definition Audio capability. The digital
audio controller in the PCH is coupled to the analog RealTek ALC268-VB1
High Definition codec.The IO Panel includes a Line-Out audio jack for driving
external powered speakers.
