Important: When a SAS cable is inserted, ensure that the connector is oriented correctly by confirming that the following conditions are met: 

GLYPH<SM590000> The pull tab must be below the connector. 

GLYPH<SM590000> Insert the connector gently until it clicks into place. If you feel resistance, the connector is probably oriented the wrong way. Do not force it. 

GLYPH<SM590000> When the connector is inserted correctly, the connector can be removed only by pulling the tab. 

GLYPH<SM590000> Cabling is done from the controller view top →  down. Top/down button up is not supported.
