Host Card LEDs
A fully linked and functional Host card will have 5 solid green LEDs, see photos below.
PWR LED: When “ON” indicates the board is powered UP.
CBL LED: Cable is present / detected
EDGE LED: This indicates that there is a link between the HIB and device connected to the card edge. This is typically a server or a
switch on an expansion chassis. A solid light indicates that it is linked at the maximum speed possible. Blinking light indicates that it
is linked a slower rates.
If only x4 CBL and EDGE LEDs are illuminated, this indicates that you are linking up to x4 only.
To achieve a x8 link, you must use (highly recommended) an OSS x8 Ipass cable and an OSS HIB25-x8 adapter card.
3 Identify ECA Device
The host card and ECA board are both transparent to the system. The system will only detects the third party PCIe card that is plugged-in to the
x16 slot of the ECA board.
Board and cable are only x8, it will only Link to x8, not a x16 link.
If you are using a x8-x4 cable (one side of the cable is connected to x4), you’ll have a x4 Link, x8 Link will not work.
If you are not using an OSS product (cable or adapter card) , the sideband signals will not provide proper operation.
4 Software Installation
No software or driver is required for the Host Adapter card and for the ECA board.
