Installation And Maintenance; Installation Guidelines - Compaq StorageWorks RAID Array 3000 Controller Shelf User Manual

This chapter describes how to install the controller shelf in a RETMA or
metric-style storage cabinet and then make the cable connections to the
Uninterruptable Power Supply (UPS), Device expansion shelves and host
system. The maintenance section describes how to interpret the status of the
LEDs on the front panel of the controller shelf. The chapter also describes how
to replace a Field Replaceable Unit (FRU).

Installation Guidelines

The controller shelf installation process consists of mounting the support
brackets for the specific number of shelves in your subsystem configuration,
setting the UltraSCSI bus termination and target ID addresses, and making the
power and SCSI cable connections between the rackmount components. The
cabling section is divided into four separate cabling procedures, one for each
of the number of device expansion shelves in your specific subsystem
configuration.

Installation and Maintenance

CAUTION: To prevent the possible loss of data, always shut down your
subsystem from the StorageWorks Command Console (SWCC). Do not turn off
system power before Shutdown is issued. When Shutdown is issued from
SWCC, the controller blinks until it has flushed the cache to the disk drive.
