Chapter 1.Overview
1.1 Introduction
This document provides backplane specific information including the features, jumper settings,
and pin definitions of 12Gb/s 4-port mini-SAS HD backplane, which is not compatible with the
previous version of SR301 chassis with screw-installed 3.5” HDD trays.
Moreover, it also lists down Chenbro worldwide technical contacts, so the user can contact our
experienced field application engineers via either a phone call or email.
1.2 Chassis Revision
The SR301 chassis has been modified to support both tool-less 3.5” HDD tray and PCI-e 3.0 slot,
and this feature-advanced chassis is named as SR301 Plus (SR301+). There is a sticker on
chassis bottom with the information of chassis revision and manufacturing code, which are must
for technical support.

Chapter 3.Function of Interface
There are various interfaces on this backplane used for connecting to mainboard and getting
system operated. Also, there are some interfaces available for system debug and configuration
purposes. All the features and signal characteristics on the interfaces will be described below.
Caution should be paid carefully to make sure the electronical characteristic is appropriate
between two ends of cables when connecting to mainboard.
3.1 SAS Connectors (CH011 / CH021 / CH031 / CH041)
There are four SFF-8482 connectors on this backplane to allow four SATA or SAS drives be
manipulated by hot-swap without powering off the server system in advance.

3.2 mini-SAS HDD Connector, CB1
For connecting to a mainboard or a HBA, this mini-SAS HD connector is applied. A proper cable
selection is essential as well to make sure good signal integrity can be maintained for the whole
connection path from mainboard or HBA/RAID card to the HDD devices.

3.3 4-pin Fan Header (JF01)
There is one 4-pin header for PWM fan, and it is alternative solution that the chassis fan can be
powered and monitored by this backplane instead of motherboard. If the chassis fan is connected
to mainboard, user needs to disable the fan monitoring function of backplane by DIP switch
(SW1).

Table 6. 4-pin Fan Header
3.4 HDD Access Mode Jumper (JP01)
This jumper allows you to configure HDD access LED and fail LED in two modes. The setting
“HDD access mode” enables that a 3.5” SATA HDD controls the activity LED through the pin 11 of
its SATA power connector. While the setting “SGPIO decode mode” is different, the HDD activity
LED is controlled by side-band SGPIO signals which also support HDD failure, indicated by a solid
red LED for each drive.

These two connectors are used to power four 3.5” hard disks, connected to this backplane, and
each can ensure that all drives are supplied with stable power inputs. If the chassis fan is also
powered by fan header (JF01), this configuration is strongly recommended.
