Identifying problems using the Light Path Diagnostics feature

If the system-error light in the operator information panel on the front of the server is
on, one or more lights inside the server might be on. Use the Light Path Diagnostics
panel to identify the type of error that occurred.
You can use the Light Path Diagnostics feature in your server to quickly identify the
type of system error that occurred. The Light Path Diagnostics panel is located inside
the Light Path Diagnostics drawer, located on the front right of the server. To access
the Light Path Diagnostic panel, press on the front of the Light Path Diagnostics
