Status LEDs

Verify the status by checking the LEDs. Controller B is located above Controller A in the center of the rear panel. The power supply/cooling units are above and below the controllers.

Facing the back panel of the FS15, the Expander ports are the outer of the two ports; the Host ports are the inner of the two ports. The ports are identified by symbols on the rear panel: a circle symbol indicates a Host port; a diamond symbol indicates an Expander port.
