Interpreting LEDs

Rear Indicator Panel Controls and LEDs

On SPARC M8-8 and SPARC M7-8 servers, the rear indicator panel is located on the CMIOU

chassis. On the SPARC M7-16 server, rear indicator panels are located on both CMIOU chassis

and on the switch chassis.

The front and rear indicator panel LEDs are always in sync. For example, if the green OK LED

is lit on the front indicator panel, the OK LED will also be lit on the rear indicator panel.
