    This guide provides information about initial hardware setup, and removal and installation of customer-replaceable units (CRUs) for the Seagate 5005/4005 Series controller enclosures, which can be used with J1212/J1224/J1284 expansion enclosures. In controller enclosures, controller modules can be purchased with either of two types of host interface: SAS or FC/iSCSI.

  • Page 13: Cnc Ports Used For Host Connection

    CNC ports used for host connection Certain models use Converged Network Controller (CNC) technology, allowing you to select the desired host interface protocol from the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface protocols supported by the system. You can use the CLI to set all controller host ports to use either FC or iSCSI protocol using the set host-port-mode CLI command.

    Logical Status LED (amber) This LED indicates a change of status or fault from something other than the enclosure management system. This may be initiated from the controller module or an external HBA. The indication is typically associated with a DDIC and LEDs at each disk position within the drawer, which help to identify the DDIC affected.

  • Page 37: System Airflow

    PCMs are hot-pluggable, and replacement should only take a few seconds to do. Replacement must be completed as soon as possible after the removal of the defective PCM to avoid a thermal exception. The replacement procedure should be completed within an absolute maximum of 2 minutes. IMPORTANT: Operation of the enclosure with any modules missing will disrupt the airflow, and the disks will not receive sufficient cooling.

    The 10GbE iSCSI ports are used in either of two capacities: • To connect two storage systems through a switch for use of replication. • For attachment to 10GbE iSCSI hosts directly, or through a switch used for the 10GbE iSCSI traffic. The first usage option requires valid licensing for the replication feature, whereas the second option requires that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O.
