2U12, 2U24, and 2U48 Expansion Chassis – Rear Panel
Components
The 2U12, 2U24, and 2U48 RAID Chassis support attachment to the 2U12, 2U24, and 2U48 Expansion
chassis. The rear of the Q2U12, 2U24, and 2U48 Expansion chassis all look the same. The expansion
chassis uses mini-SAS (SFF-8088) connectors to facilitate backend SAS expansion.
Note:
The rear panel view is common to all three expansion chassis, with the exception that 2U48
PSUs are configured with a power switch; the 2U12 and 2U24 PSUs have no power switch.
