Users Guide

An event is generated if the system continues to operate above the normally supported temperature threshold for a specified
operational time. If the average temperature over the specified operational time is greater than or equal to the warning level (> =
8%) or the critical level (> = 0.8%), an event is logged in the Lifecycle Log and the corresponding SNMP trap is generated. The
events are:
• Warning event when the temperature was greater than the warning threshold for duration of 8% or more in the last 12 months.
• Critical event when the temperature was greater than the warning threshold for duration of 10% or more in the last 12 months.
• Warning event when the temperature was greater than the critical threshold for duration of 0.8% or more in the last 12 months.
• Critical event when the temperature was greater than the critical threshold for duration of 1% or more in the last 12 months.
You can also configure iDRAC to generate additional events. For more information, see the Setting alert recurrence event section.
Viewing historical temperature data using iDRAC web interface
To view historical temperature data:
1. In the iDRAC Web interface, go to Overview → Server → Power / Thermal → Temperatures.
The Temperatures page is displayed.
2. See the System Board Temperature Historical Data section that provides a graphical display of the stored temperature
(average and peak values) for the last day, last 30 days, and last year.
For more information, see the iDRAC Online Help.
NOTE: After an iDRAC firmware update or iDRAC reset, some temperature data may not be displayed in the graph.
Viewing historical temperature data using RACADM
To view historical data using RACADM, use the inlettemphistory command.
For more information, see the iDRAC RACADM Command Line Reference Guide available at dell.com/idracmanuals.
Configuring warning threshold for inlet temperature
You can modify the minimum and maximum warning threshold values for the system board inlet temperature sensor. If reset to
default action is performed, the temperature thresholds are set to the default values. You must have Configure user privilege to set
the warning threshold values for the inlet temperature sensor.
Configuring warning threshold for inlet temperature using web interface
To configure warning threshold for inlet temperature:
1. In the iDRAC Web interface, go to Overview → Server → Power/Thermal → Temperatures.
The Temperatures page is displayed.
2. In the Temperature Probes section, for the System Board Inlet Temp, enter the minimum and maximum values for the
Warning Threshold in Centigrade or Fahrenheit. If you enter the value in centigrade, the system automatically calculates and
displays the Fahrenheit value. Similarly, if you enter Fahrenheit, the value for Centigrade is displayed.
3. Click Apply.
The values are configured.
NOTE: Changes to default thresholds are not reflected in the historical data chart since the chart limits are for fresh
air limit values only. Warnings for exceeding the custom thresholds are different from warning associated to
exceeding fresh air thresholds.
Viewing network interfaces available on host OS
You can view information about all the network interfaces that are available on the host operating system such as the IP addresses
that are assigned to the server. The iDRAC Service Module provides this information to iDRAC. The OS IP address information
includes the IPv4 and IPv6 addresses, MAC address, Subnet mask or prefix length, the FQDD of the network device, network
interface name, network interface description, network interface status, network interface type (Ethernet, tunnel, loopback, and so
on.), Gateway address, DNS server address, and DHCP server address.
