Using the AMCC 3ware®I2C Multiplexer
with a Supermicro®Backplane
The AMCC 3ware I2C Multiplexer (I2C MUX) allows you to connect a
3ware 9650SE or 9550SXU RAID controller to one of 3 Supermicro
backplanes and provide enclosure services for up to 32 drives in a
single enclosure. By using the I2C MUX and the 3ware 9.4.3 software,
you can take advantage of enclosure services such as LED signaling of
drive identification, drive fault indication, and drive rebuild indication.
The I2C MUX supports these 3 Supermicro SAS Backplanes:
•826TQ (12 drive)
•836TQ (16 drive)
•846TQ (24 drive)
This document describes how to connect an I2C MUX to a 3ware
9650SE or 9550SXU RAID controller and to one of the 3 supported
Supermicro backplanes.
What’s included in this package
•AMCC 3ware I2C Multiplexer with full-height bracket attached
•One half-height bracket (for use if needed)
•One I2C-to-controller (upstream) cable, 75 cm, #150-3101-00
•One I2C-to-controller (upstream) cable, 25 cm, #150-3102-00
•Three I2C-to-backplane (downstream) cables, 75cm, #150-3103-00
What you need
•AMCC 3ware I2C Multiplexer and connector cables (this package)
•3ware 9650SE or 9550SXU RAID controller and SATA cables
•Supermicro SAS Backplane 826TQ, 836TQ, or 846TQ
Additional documentation
This document provides information on how to connect the I2C MUX
to your 9650SE or 9550SXU RAID Controller and Supermicro
backplane.
For additional information about 3ware RAID controllers, including
use of the enclosure services, refer to the following documents.
•3ware Serial ATA RAID Controller User Guide, Version 9.4.1
•3ware Serial ATA RAID Controller User Guide, 9.4.3 Addendum
For complete information about the Supermicro backplanes, see the
appropriate documentation at Supermicro’s website.

2AMCC 3ware I2C MUX Documentation
Mounting the I2C MUX
You can mount the I2C MUX in an empty slot or any available space in
the chassis.
The I2C MUX has two break-away sections that can be removed to
make the I2C MUX card smaller. They can also be used as mounting
points for one or two Battery Backup Unit (BBU) batteries, to
maximize space usage inside the enclosure.
You may wish to install the backplane and controller in their respective
enclosures before connecting them via cables.
Connecting to Power
Power is supplied to the I2C MUX via a standard 4-pin Molex power
connector.
Cable Connections
In order for LEDs to be associated with the correct drives, the cable
connections between the I2C MUX, 3ware RAID controller, and
Supermicro backplane need to map to their corresponding port number
or port number groups.
Example: The drive cable that connects to port 1 on the 9650SE RAID
controller must connect to the port 1 SATA connector on the
Supermicro backplane. In addition, the I2C MUX port 0-7 (J4)
connector cable must use one of its two cable ends to connect to
Sideband connector #1 on the backplane, which manages I2C services
for backplane SATA ports 0-3.
The illustrations on pages 3 through 5 show the cable connection
patterns between the I2C MUX and each of the three different
Supermicro backplanes.
The 826TQ and 836TQ backplanes illustrations show a 9650SE-16ML
RAID controller and the 846TQ illustration shows a 9650SE-24M8
RAID controller.
Cable Pin Definitions
Tables showing the proper cable pin definitions are in the Appendix on
page 7.
Jumper Settings
By default, Supermicro SAS Backplanes are set to use I2C to manage
enclosure services. Therefore, the default jumper settings on the
backplanes should not normally need to be adjusted. However, if
the default settings have been changed for any reason, you will
need to change them to the I2C jumper settings.
It is a good idea to review the jumper settings and make sure they are
correct. Tables showing the proper jumper settings for each backplane
are provided in the Appendix on page 6.
