• SCSI cables
• A separately purchased BBU (a BBU is shipped in a different package)
2.7 Rackmounting
The subsystem is easily installed into a standard 19-inch rack cabinet using the
mounting holes on the sides of chassis.
The enclosure chassis can be installed using self-purchased mounting rails, or
Infortrend’s IFT-9272CEslide28 and IFT-9272CEslide36 rails.
2.7.1 Considerations for Installation Site and Chassis
• Make sure you have an appropriate site location and cables prepared with
adequate lengths to connect to main power and other devices.
• At least two people will be required to install the chassis. Disk drives should
only be installed after the chassis is properly mounted. The chassis can weigh
about 24Kgs without disk drives.
• The following tools are necessary for mounting the chassis:
