damaged connectors.
• If a fixed cable tray is available for the server, be sure the cords and cables connected to the server are
routed correctly through the tray.
• Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
• If a device has latches, be sure they are completely closed and locked.
• Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
• If problems continue to occur, remove and reinstall each device, checking the connectors and sockets
for bent pins or other damage.
• For HP ProLiant BL c-Class Server Blades, be sure the OA tray is seated properly.
