Intel SC5250-E Benutzerhandbuch

The SATA backplane provides support for SATA devices using Low Voltage Differential 
Signaling.  The backplane has a connector to accommodate a SAF-TE controller on an add-in 
card. The backplane supports four 1-inch hot-swap SATA drives when mounted in the docking 
drive carrier. When a RAID Controller SRCS14L is installed, two SATA backplanes may be 
connected for a total of eight SATA drives (valid only in 650-W redundant chassis). 

The Server Chassis SC5250-E supports only one SATA hot-swap drive bay, supporting four 
3.5-inch wide SATA hard drives. Drives are accessible by opening the front access door.  Four 
metal carriers are provided with each hot-swap bay to mount the hard drives. Each carrier 
features a plastic handle and bezel with an activity/fault indicator. When no drive is installed in a 
carrier, the air baffle should remain in place to ensure proper cooling of the hard drives.  

The Intel

®

 Server Chassis SC5250-E, hot-swap drive bay is designed to accept four one-inch 

peripherals that consume a maximum of 18 W of power each.  This wattage number is intended 
as a guideline.  Thermal performance of specific hard drives must be verified to ensure 
compliance to the drive manufacturer’s specifications.  A compatibility list of supported Intel® 
server boards for the Server Chassis SC5200 and Server Chassis SC5250-E is available on 
support.intel.com (URL: http://support.intel.com/). 

An optional hot-swap upgrade drive bay assembly (ASATAHSDB) is available for the Server 
Chassis SC5200 and Server Chassis SC5250-E. It should be mounted in place of the middle 
three 5.25-inch drive trays of the base, non-redundant chassis models.  For the redundant 
power models, the upgrade accessory should be installed in the lower three 5.25-inch drive 
trays to bring the total number of available hot-swap SATA drives to eight.  

Refer to the Intel

 Server Chassis SC5200 and SC5250-E Hot-swap Bay Upgrade Kit for 

installation instructions.  

The SATA interface for the SATA backplane provides the link between the SATA bus and the 
microcontroller.    

Each device on a SATA bus must have a unique ID.  The 4 x 1.0” backplane device ID is 
dependent on the connection to the controller.  The recommended configuration for the RAID 
Controller SRCS14L is listed in the following table.  It is important that the user follow this 
recommendation to ensure that the drive activity and fault LEDs correspond to the correct drive.  
It is not critical to follow a specific connection scheme if a different SATA controller is used as 
other controllers do not provide activity and fault LEDs via a 2x5 LED header.
