11.2.2 Cypress* CY8C22545 Enclosure Management Controller
The backplanes support enclosure management using a Cypress* CY8C22545 Programmable
System-on-Chip (PSoC*) device.
The CY8C22545 drives the hard drive activity/fault LED, hard
drive present signal, and controls hard drive power-up during system power-on.
11.3 SAS Expander Card Option RS2CV240
The expander card RS2CV240 is an optional accessory that can support more than eight 2.5”
hard disk drives. The expander card can be mounted directly behind the drive bay assembly as
shown in the following illustration.
Figure 45. Internal SAS Expander Installation
The following diagrams are used to help identify the mini-SAS connectors found on the SAS
expander cards. Care should be taken when connecting connectors from the SAS expander to
the connectors on the backplane because each connector is pre-programmed at the factory to
provide specific drive identification mapping. Improper connections may provide undesirable
drive mappings.
