Troubleshooting
NGA supports two serial console ports: com0 and com1. The NGA CLI can be accessed through either
of these ports. However, only the com0 port provides full output and interactivity during the bootup
process. The two serial console options (SoL or RJ-45 connector) cannot use com0 at the same time, so
you should assign com0 to the option you would customarily use within your environment. By default,
the NGA is configured with SoL on com0, so if SoL is your preferred method of access, then you need
not do anything more. If you prefer to assign com0 to the RJ-45 serial port, then follow the steps in

Setting up Serial Console Access through External RJ-45 Port
See
for Serial connector (RJ-45) location.
To setup serial console access through the external RJ-45 port:
Step 1
Log into the CIMC GUI.
Step 2
Click the Server tab and then click Remote Presence.
Step 3
Click the Serial over LAN tab.
Step 4
If you do not want to use Serial over LAN, uncheck the Enabled check box. This will make the serial
console accessible on com0 through the RJ-45 port. Alternatively, if you prefer to use the RJ-45 serial
console primarily, but maintain Serial over LAN as a secondary method for access to the NGA CLI, then
keep Serial over LAN enabled, but change Com Port to com1.

Step 5
Click the Save Changes button.
Console access through the RJ-45 console port will be enabled. Configure your terminal emulator or
terminal server to use 9600 baud/bps, 8-N-1 when connecting to the console.

In some cases, it may be necessary to power cycle the NGA before the serial console works. From the
CIMC GUI, click the Server tab and click Summary, and then click Power Cycle Server.
