Setting the Blower Speed Control
UltraSCSI enclosure blowers normally operate at low-speed and
provide sufficient air flow to cool the enclosure components and
ensure proper operation. Use the CLI
set emu fanspeed
command as follows to change the operating speed of the blowers:
•
Enter
set emu fanspeed=high
and all blowers in all
enclosures operate at high-speed.
•
Enter
set emu fanspeed=automatic
and the local
EMU controls the blower speed in each enclosure.
4.
EMU firmware versions 1.0 or 1.1 cannot use the
set emu
sensor_
n_setpoint=default
command. Instead, the
following command is required:
set emu sensor_
n_setpoint=nn
(where nn is the desired temperature in °C).
Table 3–4
Temperature Set Point Rules—EMU Firmware
Versions 1.2
1.
Enter all temperatures in degrees Celsius (°C). Do not use fractions,
decimals, or degrees Fahrenheit (°F).
2.
The EMU set point (sensor_3) temperature must be a minimum of
2°C (4°F) greater than the highest expected ambient (intake)
temperature.
3.
The backplane set points (sensor_1 and sensor_2) must be the same
temperature and a minimum of 12°C (22°F) greater than the highest
expected ambient temperature. This requires a minimum setting of
10°C (18°F) greater than the EMU set point.
