The Remote LAN Module (RLM) is a remote management device that is provided on the 31xx, 6040, and 6080 platforms. The RLM provides remote system management capabilities, including remote access, monitoring, troubleshooting, logging, and alerting features.
The RLM stays operational regardless of the operating state of the system. It is powered by a standby voltage, which is available as long as the system has input power to at least one of its power supplies.
The RLM has a single temperature sensor to detect ambient temperature around the RLM board. Data generated by this sensor is not used for any system or RLM environmental policies. It is only used as a reference point that might help you troubleshoot system issues. For example, it might help a remote administrator determine if the system was shut down due to an extreme temperature change.
For instructions about how to cable a system to the RLM, see the Installing or Replacing a Remote LAN Module flyer.
The following diagram illustrates how you can access the storage system and the RLM.
You use the Data ONTAP CLI to administer the system.
The RLM is directly connected to the system through the serial console. You use the Data ONTAP CLI to administer the system and the RLM.
You use the RLM CLI to monitor and troubleshoot the system.
If you have a data center configuration where management traffic and data traffic are on separate networks, you can configure the RLM on the management network.
