Chapter 8: Enclosure Management Support l 39Connecting Drive LED Control CablesDrive LED Control Cables helps you to detect/verify the faulty drives and slots in theBackplane or Enclosure. Using an internal SATA fan-out cable, connect the controller to theSATA/SAS of the backplance. Ensure that the first data connector of the fan-out cable isconnected to the port 0 of the backplane and rest of the other connectors respectively. Notethat the port 0 starts at the bottom of the connector.Note: Depending on the jumper settings, the Backplane can be configured to use either I2C orSGPIO.The four data connectors in the fan-out end must be connected to the SATA/SAS ports presentin the enclosure. The sideband connector is connected to the I2C interface of backplane, andthis helps in enabling the function of drive LEDs.Using Mini SAS (SFF-8087) cable, the SATA/SAS controller is connected to the InternalEnclosure or Backplane. This has a built-in I2C connector, which helps in enabling thefunction of drive LEDs.Behavioral Pattern of Drive LED● Initialization of drives - If a SAS drive is present, the LED will blink continously till the I/Ooperation is initiated. If a SATA drive is present, the LED glows once and then stops.● Read/Write operation in the disk -If a SAS drive is present, the LED will blink continouslytill the I/O operation is complete. If a SATA drive is present, the LED will glow till the I/Ooperation is complete.● Faulty conditions - If you encounter any errors such as bad sectors or drive failure, theFault LED will glow red untill the problem is rectified.Internal Mini SAS x4 (SFF-8087) to SATAfanout cable with sideband - connectscontroller to a maximum of four SATAdevices or a backplane.Note: The sideband (SFF-8448) connectoris used to connect with a managedbackplane or enclosure.Internal Mini SAS (SFF-8087) to SAS x4(SFF-8484) - connects to SATA/SASbackplane
