To Identify a system problem or failure through the CLI:
1
Log in to the SG210 CLI (see “Logging in to the SG210 CLI” on page 31 for information).
2
From any CLI mode, enter the following command:
sgos# show system-resource-metrics
The hardware and software system resource metrics display. These include the range for upper and
lower critical readings for each environmental statistic, followed by the current reading and threshold
status.

A Security Warning Appears for the Initial Configuration Web Page
When you open the Initial Configuration page, a security warning dialog appears. This warning indicates
that the SG210 credentials could not be verified by a known certificate authority (such as VeriSign®). This
is because the SG210 dynamically generated the self-signed credentials at the time of the last factory
reset—they are not registered with a known certificate authority.
Normally, accepting such a credential represents a security risk because of the possibility of a
man-in-the-middle attack. However, when you have connected your PC directly to the SG210, as
described in this guide, a man-in-the-middle attack is impossible. The SG210 has not yet been configured
and is connected directly to your PC. The Initial Configuration Web page is accessible only through a
SG210 that has not yet been configured.
You can verify that the serial number in the credential matches the serial number printed on the SG210 if
you want to be absolutely certain that you have connected to the correct device.
