Introduction
About this Guide
The SAS expander backplane user’s manual provides the information for functions,
capabilities, configuring and assembly / disassembly of this backplane.
Introducing the SAS Expander
SAS expander expands one SAS address to a number of additional ports. It is an optimal
device for usage in data centers.
The CHENBRO SAS Expander Backplane provides high performance, 24 x 2.5” disk drives
connectivity and flexibility in RM235/RM418/RM417. It is a valuable solution to other
expansive and complex topologies. The SAS expander is ideal for high availability,
scalable server clustering environments, front-end storage subsystems used in clusters,
SANs and NAS environments.
The CHENBRO SAS Expander Backplane is based on LSI SAS2 X36 IC that enables the
connection of 24 drives in directly attached SAS or SATA HDD. This Backplane performs
SAS and SATA transfer rate at 6.0 Gb/s or 3 Gb/s with individual configurations.
The SAS expander IC supports the Serial SCSI Protocol (SSP), SATA Tunneled Protocol
(STP) and Serial Management Protocol (SMP). Those are based on SAS protocol and
described in the SAS standard.
Backplane

Features
General
• To expand one Mini-SAS port (SFF-8087) to 24 x SATAII/SAS 2.5” HDD
• Support HDD Failure / Activity Indication and HDD ID Mapping
• Support RM235/RM418/RM417 only
High-Speed I/O
• 6.0 Gb/s or 3.0 Gb/s operations
• Automatic negotiation of linking speed
Application
• SAS / SATA HDD NAS storage sever or enclosure
• Security system
• Video streaming / editing workstation
SAS expander Backplane must be used only with SAS RAID card
The supported HDD quantity is depended on the capability of the
SAS RAID card in the system.

How To Assemble On The HDD Cage
Step 1 : Attach three “ L “ shape metal brackets on the backplane by screw
Step 2 : Fasten backplane on the rear side of HDD cage by screw
Step 3 : Insert two bridge boards on the backplane

Step 4 : Screwing four studs on the backplane
Step 4 : Ducking SAS Expander daughter board on the bridge board
Step 5 : Align with the screwing hole on the studs and fasten by four screws to finish
whole HDD Cage assembly
Note : Regarding assembly for HDD cage on the chassis ,
