Note: The 2145 uninterruptible power supply-1U (2145 UPS-1U) does not power
off when the SAN Volume Controller is shut down from the power button.
The amber check LED is used to indicate critical failures on the service controller.
If the check LED is off and the power LED is on, the service controller is working
correctly.
If the check LED is on, a critical service controller failure was detected.
The check LED is also on while the service controller code is being reprogrammed.
For example, when the SAN Volume Controller cluster code is being upgraded, the
check LED is on. It is normal for the power LED to be on at this time.
The operator information panel contains indicators and buttons for the SAN
Volume Controller 2145-8F2 or SAN Volume Controller 2145-8F4.

The release latch gives you access to the light path diagnostics panel, which
provides a preliminary method of determining the location of a problem.
After pressing the release latch on the information panel, you can slide the light
path diagnostics panel out to view the lit LEDs. The LEDs indicate the type of
error that has occurred. Light path diagnostics are described in more detail in the
light path maintenance analysis procedure (MAP).
To retract the panel, push it back into the node and snap it into place.
