For information about front panel controls and indicators, see “Front Panel
Indicators” on page 9.
The system is configured with up to eight disk drives, which are accessible from the
front of the system.
Front Panel Indicators
Several front panel indicators provide general system status, alert you to system
problems, and help you to determine the location of system faults.
During system startup, the indicators are toggled on and off to verify that each one
is working correctly. Indicators located on the front panel work in conjunction with
specific fault indicators. For example, a fault in the power supply subsystem
illuminates the power supply Service Required indicator on the affected power
supply, as well as the system Service Required indicator. Since all front panel status
indicators are powered by the system’s standby power source, fault indicators
remain lit for any fault condition that results in a system shutdown.
At the top left of the system as you look at its front are six system status indicators.
Power/OK indicator and the Service Required indicator provide a snapshot of the
overall system status. The Locator indicator helps you to quickly locate a specific
system even though it may be one of numerous systems in a room. The Locator
indicator/button is at the far left in the cluster, and is lit remotely by the system
administrator, or toggled on and off locally by pressing the button.
