The Power light, which is green, comes on and stays on continuously
when power is supplied to the 2104 by one or both of the
fan-and-power-supply assemblies within the 2104.
The Check light, which is amber, comes on if a failure occurs in the 2104.
Note: The 2104 might be able to continue operating correctly even when
