Chapter 3. Physical specifications
PC 300PL — tower
Dimensions
Height: 492 mm (19.4 in.)
Width: 200 mm (7.9 in.)
Depth: 445 mm (17.5 in.)
Weight
Minimum configuration as shipped: 15 kg (33 lb)
Maximum configuration: 17.3 kg (38 lb)
Environment
Air temperature:
– System on: 10° to 35°C (50° to 95°F)
– System off: 10° to 43°C (50° to 110°F)
– Maximum altitude: 2134 m (7000 ft)
Note: The maximum altitude, 2133.6 m (7000 ft.), is
the maximum altitude at which the specified air
temperatures apply. At higher altitudes, the
maximum air temperatures are lower than those
specified.
Humidity:
– System on: 8% to 80%
– System off: 8% to 80%
Electrical input
Input voltage:
– Low range:
- Minimum: 90 V ac
- Maximum: 137 V ac
- Input frequency range: 57–63 Hz
- Voltage switch setting: 115 V
– High range:
- Minimum: 180 V ac
- Maximum: 265 V ac
- Input frequency range: 47–53 Hz
- Voltage switch setting: 230 V
– Input kilovolt-amperes (kVA) (approximate):
- Minimum configuration as shipped: 0.08 kVA
- Maximum configuration: 0.38 kVA
Note: Power consumption and heat output vary depending
on the number and type of optional features installed
and the power management optional features in use.
Heat output
Approximate heat output in British thermal units (Btu) per
hour:
– Minimum configuration: 245 Btu/hr (70 watts)
– Maximum configuration: 969 Btu/hr (285 watts)
Airflow
Approximately 0.85 cubic meter per minute (30 cubic feet
per minute) maximum
Acoustical noise-emission values
Average sound-pressure levels:
– At operator position:
- Idle: 36 dBA
- Operating: 39 dBA
– At bystander position–1 meter (3.3 ft):
- Idle: 33 dBA
- Operating: 36 dBA
– Declared (upper limit) sound-power levels:
- Idle: 4.7 bels
- Operating: 5.0 bels
Note: These levels were measured in controlled acoustical
environments according to procedures specified by the
American National Standards Institute (ANSI) S12.10 and
ISO 7779 and are reported in accordance with ISO 9296.
Actual sound-pressure levels in a given location might
exceed the average values stated because of room
reflections and other nearby noise sources. The declared
sound-power levels indicate an upper limit, below which a
large number of computers will operate.
Cabling requirements for Wake on LAN adapters
The PC 300PL Personal Computer has a 3-pin header on the system board that provides the Auxiliary 5
volts (AUX5) and wake-up signal connections. Newer Wake on LAN adapters have a single 3-pin header
that connects to the 3-pin header on the riser card. Some Wake on LAN adapters have two headers: a
3-pin, right-angle header for AUX5, and a 2-pin straight header for the wake-up signal. These Wake on
LAN adapter options include a Y-cable that has a 3-pin system board connector on one end and splits into
the 3-pin and 2-pin connectors that connect to the adapter.
