    • Power−The cabinet and StorageWorks shelves are configured for redundant power. This configuration consists of two cable distribution units (CDUs) in the cabinet and two power supplies in each shelf. Each CDU requires a different power source. The primary shelf power supply connects to CDU A and the redundant shelf power supply connects to CDU B.

  • Page 12: Array Controller Software

    1.3.7 Array Controller Software The array controller operating software (HSOF) is the software component of the controller. It processes SCSI I/O requests from the host and performs the device-level operations required to satisfy the requests. 1.3.8 Fan Trays The bottom rear-mounted fan tray occupies one shelf to provide improved cooling for 7200 rpm devices, such as the RZ29B-series disk drive.

  • Page 19 The 8-Bit I/O module is located on the right side of the SBB shelf to the right of slot 0 (see Figure 2-1). On the front of the I/O module (see Figure 2-7) are two 50-pin female connectors: bus connector JA1, the data input connector, and bus connector JB1, the data output connector. In a split-bus configuration, both JA1 and JB1 are input connectors.

  • Page 20: Data Bus Connections

    2.4.1 Data Bus Connections The I/O module provides an external connection for the SBB shelf buses. The backplane connector on the rear of the I/O module (see Figure 2-7) routes the bus and control signals from the shelf backplane to the I/O module circuits. These circuits connect the lower eight bits (0 through 7) of bus A to external bus connector JA1 and the lower eight bits of bus B to external bus connector JB1.

  • Page 21: Sbb Ecb Shelf Fault Notification

    2.5 SBB ECB Shelf Fault Notification This section describes the SBB ECB and provides information to assist you in interpreting the fault LEDs. The external cache batteries are mounted in an SBB shelf without a backplane. The shelf is a repository for ECBs only (see Figure 2-8). The ECB is connected to the array controller’s cache module by an external cable (see Figure 2-9).
  • Page 22 The cache module is mounted under the controller and is identified by the single plug in the middle of the module (see Figure 2-9). _________________________ Note ______________________________ The cables connecting the cache module to the ECB are factory installed. To remove or replace the controller, cache, or ECB, refer to the Servicing Your StorageWorks Subsystem manual.
  • Page 23 Each ECB supports two cache modules. To check the ECB status, look at the ECB status indicator LED (one for each cache module) for the appropriate indication (see Table 2-3 and Figure 2-10). Table 2-3 ECB Status Indications LED status Battery status System power is on, and the ECB is fully charged.
