PCIe x16 host card). To check the functional status the enclosure of the Ndigo Crate has to be
open as the control LEDs are installed on the base board beside each slot.
The Ndigo Crate is capable of any link width up to the number of lanes electrically connected
at the slot (x4 or x8, see Table 7). This might not be true for all third party PCIe boards. The
negotiated link width will be the maximum width supported by both the third party PCIe board
and the Ndigo Crate (Table 3.3 ).
