Understanding LED hardware indicators

This topic provides information for understanding the LED status of all system
components. If you do not have an LED issue or direct access to the system,

File node hardware indicators for 2073-720

Use this information to evaluate the system LEDs, which can often identify the
source of an error.
Light path diagnostics is a system of LEDs on various external and internal
components of the server. When an error occurs, LEDs are lit throughout the
server. By viewing the LEDs in a particular order, you can often identify the source
of the error.
When LEDs are lit to indicate an error, they remain lit when the server is turned
off, provided that the server is still connected to power and the power supply is
operating correctly.
Before you work inside the server to view light path diagnostics LEDs, read the
safety information.

Definition and Action
This state indicates the Fibre Channel
adapter is attempting to resync the Fibre
Channel connection. This situation is
normally seen after a Fibre Channel
connection is unplugged and then plugged
back in.
There is no connection detected at all at the
file module Fibre Channel port. This broken
connection is most likely caused by a Fibre
Channel cable or the Fibre Channel adapter
has failed.
Definition and Action
This state indicates a good connection status.
There is no connection detected at all at the
node canister Fibre Channel port.
