Procedure: Understanding the system status using the LEDs

This procedure helps you determine the system status using the LED indicators on
the system.
About this task
The LEDs provide a general idea of the system status. You can obtain more detail
from the management GUI and the service assistant. Examine the LEDs when you
are not able to access the management GUI or the service assistant, or when the
system is not showing any information about a device.
The procedure shows the status for the enclosure chassis, power supply units and
batteries, and canisters. It does not show the status for the drives.
The first step is to determine the state of the control enclosure, which includes its
power supply units, batteries, and node canisters. Your control enclosure is
operational if you can manage the system using the management GUI. You might
also want to view the status of the individual power supply units, batteries, or
node canisters.
Find the control enclosure for the system that you are troubleshooting. There is one
control enclosure in a system. If you are unsure which one is the control enclosure,
go to "Procedure: Identifying which enclosure or canister to service" on page 52.

power failure LEDs on each power supply unit in the enclosure to determine if
there is power to the system, or if there are power problems. Figure 21 on page
55 shows the LEDs on the power supply unit for the 2076-112 or 2076-124. The
LEDs on the power supply units for the 2076-312 and 2076-324 are similar, but
they are not shown here.
