Cabling internal hard disk drives to a ServeRAID adapter (optional)


Cabling internal hard disk drives to a ServeRAID adapter (optional)

You can install an optional ServeRAID adapter in the server to enable you to configure the internal hot-swap hard disk drives into disk arrays.
To do this, you must disconnect the cable from the integrated SCSI controller on the I/O function card, and connect the cable to a ServeRAID adapter.
To cable a ServeRAID adapter to the internal hard disk drives in the server, or to make this adapter a startup device, you must install the ServeRAID adapter in PCI slot 10, 11, or 12.
Refer to the ServeRAID adapter option documentation for complete instructions on installing a ServeRAID adapter in the server.

The following procedure describes the cable routing that is necessary when you install the ServeRAID adapter.
Refer to the following illustration while you perform the steps in this procedure.

Notes:

  1.  It might be easier for you to route the cable before you install the adapter.
  2.  You do not have to remove the I/O function card or the screws on the I/O function card to connect  the internal SCSI cable to a ServeRAID adapter.
     
     -1- Standard internal SCSI cable location for connection to internal SCSI port B
     -2- Internal SCSI port B
     -3- New internal SCSI cable location for connection to ServeRAID adapter

  3.  Disconnect the internal SCSI cable -1- from internal SCSI port B -2- on the I/O function card.
  4.  Change the setting of the three-pin, SCSI B detect jumper (identifier J19) on the I/O function card from  pins 1 and 2 to pins 2 and 3.
     This prevents the server from displaying a non-applicable error message, Cable not present .
     
    Note: For additional information on changing jumper settings, see 'Jumper settings'.
     For the jumper location, see the illustration of the I/O function card in 'I/O function card component locations'.

  5.  The SCSI cable comes with two standard folds.
     Unfold the SCSI cable at the fold that is closer to the connector on the end of the cable.
     If necessary, refer to the illustration at the beginning of this procedure.
  6.  Install the ServeRAID adapter in PCI slot 10, 11, or 12.
  7.  Connect the internal SCSI port B end of the SCSI cable to the appropriate channel on the ServeRAID  adapter -3-. Refer to the ServeRAID adapter option documentation for instructions on installing a  ServeRAID adapter in the server and connecting the SCSI cable to the ServeRAID adapter.
