Troubleshooting in chassis
The Troubleshoot option on the OME–Modular home page enables you to use the following options to resolve issues that occur
in the chassis:
● Extract Log—Use this option to extract application logs and save them to the NFS or CIFS locations on the network.
● Diagnostic Commands—Use this option to run diagnostic commands and parameters to troubleshoot the chassis network.
● Reset Management Module—Use this option to reboot the management module (MM) in a single management module
configuration, and perform a failover in a dual MM configuration.
NOTE: During a factory reset process, the synchronization takes about 3-5 minutes. During this period, the serial, KVM,
and Quick Sync interfaces do not accept the factory password and the login attempt fails.
● Terminate Serial Connection—Use this option to end the existing serial sessions.
Blinking LEDs
You can use the Blink LED option on the OME–Modular home page to turn off or turn on the chassis LED.

Remote RACADM command-line
interface
Use this command-line utility to manage OME–Modular and its components. You can
use remote or firmware RACADM:
● Remote RACADM is a client utility that runs on a management station. It uses the
out-of-band network interface to run RACADM commands on the managed system
and uses the HTTPs channel. The –r option runs the RACADM command over a
network.
● Firmware RACADM is accessible by logging in to OME–Modular using SSH or telnet.
You can run the firmware RACADM commands without specifying the OME–
Modular IP, user name, or password. After you enter the RACADM prompt, you can
directly run the commands without the racadm prefix.
NOTE: A log for remote racadm session (login or logout) is displayed in the Audit
Logs page, irrespective of the remote racadm status. However, the feature does
not work if the remote racadm option is disabled.
LCD Use the LCD on the front panel to:
● View alerts, OME–Modular IP or MAC address.
● Set DHCP
● Configure OME–Modular static IP settings.
● View OME–Modular MAC address for the active MM.
