1 Expansion Pedestal Option This guide describes how to install the Expansion Pedestal Option to expand the storage capability of the RAID Array 3000 subsystem. The guide provides a product description of the option and how to connect it to the base pedestal to create an enhanced storage subsystem. 1.0 Introduction This guide contains installation instructions needed to interface the expansion pedestal to the base pedestal to create your expanded storage subsystem.
RAID Array 3000 Storage Subsystem Expansion Pedestal Option Figure 1–1 Expansion Pedestal 2.1 Expansion Pedestal Cabinet The expansion pedestal cabinet is a modular free-standing storage cabinet that is completely self contained with dual fan-cooled power supplies, an internal UltraSCSI single-ended extender module, and an internal EMU circuit board.
Chapter 1.
RAID Array 3000 Storage Subsystem Expansion Pedestal Option Figure 1–3 Rear Panel Power Supplies 2.2 Expansion Pedestal Components The expansion pedestal contains a 16-bit, wide/differential UltraSCSI bus, an Environmental Monitor Unit (EMU), a SCSI bus extender module, and two universal 50/60 Hz, 100 – 240 Vac fan-cooled power supplies. The single-ended UltraSCSI bus is factory-configured as one continuous bus that runs along the backplane between the disk drive connectors and the internal cables.
Chapter 1. Expansion Pedestal Option The EMU (Figure 1-4) is an internal circuit board, which monitors the operation of the pedestal. The EMU monitors power supply voltages, fans, temperatures that are reported to the user, and controls (turns on and off) the audible alarm and status LED on the front panel of the pedestal. It is connected to the SCSI bus and powered by internal cabling.
RAID Array 3000 Storage Subsystem Expansion Pedestal Option The RAID Array 3000 base pedestal is factory-configured for split-bus operation. You must reconfigure the bus in the base subsystem from split-bus to a “throughbus” configuration prior to connecting the expansion cabinet to the base subsystem. The components needed to reconfigure the split-bus in the base subsystem are included with your pedestal expansion kit option.
