To check the sensor status and values of your system, you can use either the IPMI command or the BMC Web UI. Both methods provide you with information about the various sensors in your system, such as temperature, voltage, fan speed, and power supply status.

IPMI Command

Example: Get sensor list using the IPMI command

BMC Web UI

• To open the Sensors page, click Hardware status > Sensors from the menu bar. The Sensors page displays all the sensor related information.

  

Redfish

• Command format

  curl -k -X GET
  https://<username>:<password>@<BMC
  IP>/redfish/v1/Chassis/c885a_Sensor/<sensor type>

  Note	The <sensor type> refers to the following: Sensors: Contains the wattage of the power and status of the sensor. Thermal: Contains the sensor temperature and fan speed.

The BMC facilitates a range of LED functionalities, succinctly presented in the following Table:

The following are the System Fault conditions:

• Fan Failure.

• The component temperature reading exceeds the threshold.

• PSU not detected.

• PSU Failure.

The following are the Fan Failure conditions:

• Fan not detected.

• BMC unable to reading fan speed.

• Fan speed reading is 0.

• Fan speed below the threshold.

OpenBMC provides diverse interface, including Web GUI, Redfish, and IPMI commands, to facilitate users in the comprehensive management of the BMC's network.

Network configuration encompasses a multitude of facets, encompassing tasks such as configuring IP addresses, IP addresses source, gateways, and other pivotal elements.

The following are some fundamental network configuration features:

• IP Addresses Source

• IP Address

• Gateways

IPMI Command

• Set IP address source command format:

Ipmitool lan <channel> set ipsrc
<source>channel:eth0 = 1Note: Here,
<source> refers to the following:static = address manually
configured to be staticdhcp = address obtained by BMC running
DHCP

• Set channel IP address command format:

Ipmitool lan <channel> set ipaddr
<x.x.x.x>

• Set channel IP netmask command format:

Ipmitool lan <channel> set netmask
<x.x.x.x>

BMC Web GUI

Toggle DHCP button to enable or disable DHCP. After enabling DHCP, the IPv4 address will be automatically configured. When disabling DHCP, the IPv4 address will be manually configured.

After disabling DHCP, it pops the “Add Static IPv4 address” window to configure the IPv4 address. In the "Add Static IPv4 Address" window, enter the IP address, gateway, and subnet mask. Click “Add” button to add the static IPV4 address.

Click the "OK" button to apply the static IPv4 address configuration.

It will pop up an "Information" window, notifying the user to login to the BMC Web GUI using the new IP.

Redfish

• Command format:

curl -k -X PATCH
https://<username>:<password>@<BMC
IP>/redfish/v1/Managers/bmc/EthernetInterfaces/eth0 -H

How to enable/disable ssh/ipmi function

This procedure explains how to enable or disable the SSH (Secure Shell) and IPMI (Intelligent Platform Management Interface) functions within your system. By enabling these functions, you can gain remote access and management capabilities. Disabling them can help enhance security by limiting remote connectivity.
