Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required be-
fore any warranty service will be rendered. You can obtain service by calling your
vendor for a Returned Merchandise Authorization (RMA) number. When returning
to the manufacturer, the RMA number should be prominently displayed on the
outside of the shipping carton, and mailed prepaid or hand-carried. Shipping and
handling charges will be applied for all orders that must be mailed when service
is complete.
For faster service, RMA authorizations may be requested online (http://www.super-
micro.com/support/rma/).
Whenever possible, repack the backplane in the original Supermicro box, using the
original packaging materials. If these are no longer available, be sure to pack the
backplane in an anti-static bag and inside the box. Make sure that there is enough
packaging material surrounding the backplane so that it does not become damaged
during shipping.
This warranty only covers normal consumer use and does not cover damages in-
curred in shipping or from failure due to the alteration, misuse, abuse or improper
maintenance of products.
During the warranty period, contact your distributor rst for any product problems.

SAS-827T Safety Guidelines
To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.
1-1 ESD Safety Guidelines
Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-
age to your system, it is important to handle it very carefully. The following measures
are generally sufcient to protect your equipment from ESD.
Use a grounded wrist strap designed to prevent static discharge.•
Touch a grounded metal object before removing a component from the antistatic •
bag.
Handle the backplane by its edges only; do not touch its components, peripheral •
chips, memory modules or gold contacts.
When handling chips or modules, avoid touching their pins.•
Put the card and peripherals back into their antistatic bags when not in use.•
1-2 General Safety Guidelines
Always disconnect power cables before installing or removing any components •
from the computer, including the SAS-827T backplane.
Disconnect the power cable before installing or removing any cables from the •
SAS-827T backplane.
Make sure that the SAS-827T backplane is securely and properly installed on •
the motherboard to prevent damage to the system due to power shortage.

5. - 8. Chassis Fan Connectors
These connectors, designated JP54, JP55, JP56 and JP57 supply power to the
chassis cooling fans.
9. - 12. Fan Connector Y-Cable
(Optional feature, sold separately)
A Y-cable is used to connect the fan connector from the backplane to the mother-
board's fan connectors. These fan connectors are designated JP58, JP59, JP60 and
JP65. Only connect a Y-cable into these four connectors. Never directly connect a
fan to these connectors as it may damage both the fans and/or the backplane.

21. Manufacturer's Test Connectors
The manufacturer's test connectors are desig-
nated JP26 and JP49. These test connectors
are for manufacturing use only.
20. Upgrade Connector
The upgrade connector is designated JP69.
Upgrade connectors are for manufacturing
use only.
16. - 19. Motherboard to Backplane Con-
nectors
These connectors, designated JF1, JF2,
JF3 and JF4, connect the motherboards to
the front LED panels on the chassis. JF1
connects to motherboard A. JF2 connects
to motherboard B. JF3 connects to mother-
board C and JF4 connects to motherboard
D. See the table on page 2-2 to determine
the locations of the motherboards within
the chassis.
14. - 15. Backplane to Front Panel Headers
These connectors are designated JF5 and
JF6. They connect the backplane to the
front LED panels on the chassis. JF5 con-
nects to the LED display panel for mother-
boards A and B. JF6 connects to the LED

22. - 33. SAS Ports
The SAS-827T backplane is designed with
four separate sectors, which support from
one to four motherboards independently
of each other. The SAS ports are used to
connect the SAS drive cables. The 12 ports
are designated A0, A1, A2, B0, B1, B2, C0,
C1, C2 and D0, D1, D2. Each port is also
compatible with SATA drives. Use the table
below to determine the SAS port to moth-
erboard conguration that is appropriate for
your system.

Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identied with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.

*The buzzer sound indicates that a condition requiring immediate attention has
occurred.
The backplane buzzer alarm is triggered by the following condition:
Backplane temperature over 45º, 50º or 55º Celsius, depending upon the overheat
setting selected. See the table above for details.
