2.3 Appliance Chassis
The chassis consists of a sheet metal enclosure assembly containing an integrated backplane PCB,
Enclosure Management Card (with audible alarm) and drive carrier runner system. A bezel is attached
to the front.
The chassis is fitted with 19-inch rack mounting features which enables it to be fitted to standard 19-
inch racks and uses 2U (3.5 inches) of rack space.
The backplane PCB provides 12 direct dock SAS connectors to the drives and acts as the connectivity
hub of the appliance, connecting to the EM Card.
The ten cooling fans are connected to the system through the EM Card.
There are 12 drive bays at the front of the appliance. Each drive bay accommodates a plug-in drive
carrier module which houses low profile (1 inch) high 3.5-inch form factor drives.
Note A bay is defined as the space required to house a single 1.0" high 3.5-inch disk drive in its carrier
module.
At the rear, the chassis assembly accommodates two Power Supply Units and the ATX server
subsystem.
The top cover on the appliance provides access to the cooling fans and the ATX server subsystem.
Important The cover should only be removed by service personnel as it provides access to a service area.
Upon replacement, the cover MUST be secured by turning the lock mechanism to the “locked”
position with a screwdriver (see
