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.

#1. Activity LED Headers
The activity LED headers, designated JP26
and JP47, are used to indicate the activity
status of each SAS drive. The activity LED
headers are located on the front panel. For the
activity lead headers to work properly, connect
to them using a 10-pin LED cable. This is only
used when the activity LED is not supported
by the hard drive.
#2. MG9071 and MG9072 Chips
The MG9071 and MG9072 are enclosure
management chips that support the SES-2
controller and SES-2 protocols.

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.
