slot.

The LED’s indicate the following:

This indicates that the full lane width has been established for that slot e.g. x4 card in
a x4 slot

Flashes on for 0.5 seconds then off for 1.5 seconds.

This indicates that a reduced lane width has been established and the slot is not
working to maximum efficiency e.g. a x1 card inserted into a x4 slot.

No LED’s flashing.

This indicates that lane width has not been established.

The LED’s will not flash on slots where no cards are fitted.
