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.
