11.1.3 Checking the System Environment


11.1.3 Checking the System Environment
The showenvironment command displays all of the system sensor values. With knowledge of the system intake temperature, voltage, and fan speed, the system administrator can check for any abnormalities in the system operating environment. Also, with knowledge of the power consumption and exhaust airflow of the system, the facility manager can identify potential energy reductions at parts of the system installation site.
Operation Procedure
  1. Execute the showenvironment command to check the system environment information and voltages.
    The following example displays the intake temperatures.
XSCF> showenvironment

Temperature:30.71C
BB#01
Temperature:29.97C

Ambient Temperature and Fan Speed Level
As a result of setting the altitude of the installation location, the fan speed level varies according to the ambient temperature. The higher the level number for the fan speed level, the faster the fan speed.

Table 11-4 lists the fan speed levels displayed by the showenvironment command, for the corresponding set altitudes and ambient temperatures.
Table 11-4  Fan Speed Levels Corresponding to Altitude and Ambient Temperature (Common to the SPARC M12/M10)
Fan Speed Level Ambient Temperature by Altitude
  500 m or Lower 501 to 1000 m 1001 to 1500 m 1501 to 3000 m
High speed
(level-3 ->level-4)
31°C or higher 29℃ or higher 27℃ or higher 25℃ or higher
Middle speed
(level-4 ->level-3)
29°C or lower 27℃ or lower 25℃ or lower 23℃ or lower
Middle speed
(level-2 ->level-3)
26℃ or higher 24℃ or higher 22℃ or higher 20℃ or higher
Low speed
(level-3 ->level-2)
24℃ or lower 22℃ or lower 20℃ or lower 18℃ or lower
Low speed
(level-1 ->level-2)
22℃ or higher 20℃ or higher 18℃ or higher 16℃ or higher
Low speed
(level-2 ->level-1)
20℃ or lower 18℃ or lower 16℃ or lower 14℃ or lower
Operation Procedure
  1. Execute the showenvironment command to check the fan speed level.
    The following example specifies the Fan operand to display the fan speed level of the fan units.
XSCF> showenvironment Fan

Power Consumption and Exhaust Airflow
Use the power monitor function and airflow indicator to display the power consumption and exhaust airflow of the system. The power monitor function and airflow indicator enable routine checks of the amount of actual power consumption by the system in operation, as well as the exhaust airflow volume.

Use the showenvironment power command to display the power consumption. The command displays the power consumption value of the system, the maximum power consumption value (Permitted AC power consumption) and actual power consumption value (Actual AC power consumption) in the chassis, etc. If the power supply type is DC, "...DC power..." is displayed instead.
Note - In SPARC M12 systems, the rated power consumption in the chassis is displayed as "Available AC power consumption."
Use the showenvironment air command to display the exhaust airflow. The SNMP agent function can also be used to acquire power consumption and exhaust airflow information.
To acquire power consumption and exhaust airflow information through the SNMP agent function, install the latest XSCF extended MIB definition file for the SNMP manager. For the place to obtain the XSCF extended MIB definition file, see the latest Product Notes for your server or the MIB definition file-related information at the firmware download site.
Note - In the following cases, the power consumption and exhaust airflow values may not be correctly displayed by MIB information, the showenvironment power command, the showenvironment air command, and XSCF Web. Check the values again after one minute.

- During system power-on/off or during a short period after the power-on/off is completed

- During active replacement of a power supply unit or during a short period after the active replacement is completed
Note - The PCI expansion unit and peripheral I/O devices are not included in power consumption and exhaust airflow information.
Operation Procedure
  1. Execute the showenvironment command to check the exhaust airflow of the system.
    The following example specifies the air operand to display the exhaust airflow of the system.
XSCF> showenvironment air
BB#00
Air Flow:306CMH
Note - The unit of exhaust airflow (CMH = m3/h) indicates how many cubic meters of airflow are generated per hour.
  1. Execute the showenvironment command to check the power consumption of the system.
    The following example specifies the power operand to display power consumption information. The display content shows, from the top, the maximum power supply value of the power supply unit (PSU) for the entire system, the minimum power consumption value and maximum power consumption value of the system, followed by the maximum power consumption value and actual power consumption value of the chassis.
XSCF> showenvironment power
Power Supply Maximum :5000W
Installed Hardware Minimum:1268W
Peak Permitted :2322W
BB#00
Permitted AC power consumption:5000W
Actual AC power consumption :1719W
Note - The measurement values of the power monitor and airflow indicator are reference values. Their values vary depending on the system load.
