Front Panel LED Descriptions

• LED 1 System Power
This LED illuminates green when the system power is applied. If this LED is off, either the system is powered
off or there is a power failure in the system. Troubleshoot to identify the cause.
• LED 2 System ID
This LED illuminates blue when activated and is used to identify the storage system among the other systems
installed in the rack. This LED is normally off and illuminates only during the identification process initiated
by the application.
LED 3 Host Connectivity
•
This LED illuminates green when a host port is linked up with either IOM.
• LED 4 Fault - Main Bay
This LED illuminates amber when experiencing a system hardware fault. The hardware fault can be initiated by
GEM for a component or FRU that is accessible through the main bay cover. This LED is normally off. Pull
the chassis forward from its installed position within the rack, remove the main bay cover and look for amber
colored LED on any disc drives or HS expander modules. Replace the faulty component. If no LED is
illuminated in the Main Bay then contact Seagate support.
• LED 5 Fault - Application
This LED illuminates amber when experiencing a system fault that is initiated by the Application (Host). This
LED is normally off.
