If you have the Chassis Administrator privileges, you can perform the following tasks in this tab: • Power Control tasks: • Power Off (Non-graceful)-Turns off the server power, which is equivalent to pressing the power button when the server is turned on. This option is disabled if the server is already turned off. It does not notify the server operating system. • Power Cycle System (Cold Boot)-Turns off and then restarts the server (cold boot). This option is disabled if the server is already turned off. NOTE: When the chassis is power cycled all devices in the chassis are also powered cycled. The management module does not get power cycled. But, alerts are logged indicating that the connectivity to devices is lost owing to the power cycle operation. • Power Off (Graceful)-Notifies the server operating system to turn off the server. This option is disabled if the server is already turned off. • Configuration tasks: • Create Chassis Group • Join Chassis Group • Initial Configuration • Troubleshooting tasks: • Extract Log-You can extract the logs to a CIFS or NFS share, or a local drive on your system. • Diagnostic Commands • Reset management module • Terminate serial connection • Turn-on or turn off LEDs using Blink LED. • Back up, restore, export chassis profile, and perform failover. NOTE: After a chassis power off, the compute SLEDs are polled based on the event from the chassis. Each event from the chassis triggers a health-poll. You may see multiple connection loss events from compute SLEDs. Wiring chassis The automatic uplink detection and network loop prevention features in OME-Modular facilitate connection of multiple chassis with cables. The wiring saves port usage in the data center switches and access each chassis in the network. The cabling or wiring of chassis in this way is called stack. While wiring a chassis, connect one network cable from each management module to the Top of Rack (ToR) switch of the data center. Ensure that both the ports on the ToR are enabled and are in the same network and VLAN.
