Chassis
The chassis is a sheet-metal housing which contains a passive midplane and chassis
slots for the RAID Controllers, or Loop Bypass Boards, disk drives, power supplies,
and the fan modules.
Each chassis includes a chassis address switch on the midplane board that must be set
to a unique address 0 through 9 during installation. Refer to your PVS Series
Installation Guide or the Open SAN Installation Manual for information on setting the
chassis address switch depending how the PFR600 Series RAID is used. See also,
“Chassis address setting requirement” on page 28 .
The following diagram shows how disk modules are identified based on the chassis
address and physical location. The chassis with an address set to 0 contains drives
from 1 to 10; the chassis with an address set to 1 contains drives from 11 to 20; and
so forth.
Midplane
The midplane distributes power and signals to all the chassis components. All FRUs
plug directly into midplane connectors. The midplane includes a chassis address
switch that must be set during installation. Refer to
“Chassis address setting
requirement” on page 28 for information on setting the chassis address.
