(see p.6, No. 16)
Consult the documentation that comes with your SATA DOM and check whether or not Pin 7 requires 5V power supply.
If the connected SATA DOM requires 5V power supply, move the jumper c aps placed on the SATA DOM Power Jumper (SATAPWR1) from pins 2-3 (default) to pins 1-2.
If the connected SATA DOM does NOT require 5V powe r supply, connect the SATA DOM power cable to the SATA DOM power header (SATA_ PWR1) and there is no ne ed to change the default jumper setting of the SATA DOM Power Jumpe r (pins 2-3).
Warning! Incorrec t setting of the SATA DOM Power Jumper (SATAPWR1) may cause dam­age to the motherboard or your SATA DOM.

2.11 Dual LAN and Teaming Operation Guide

Dual LAN with Teaming enabled on this motherboard allows two single
connections to act as one single connection(s) for twice the transmission
bandwidth, making data transmission more eective and improving the quality of
transmission of distant images. Fault tolerance on the dual LAN network prevents
network downtime by transferring the workload from a failed port to a working
port.
e speed of transmission is subject to the actual network environment or status even with Teaming enabled.
Before setting up Teaming, please make sure whether your Switch (or Router)
supports Teaming (IEEE 802.3ad Link Aggregation). You can specify a preferred
adapter in Intel PROSet. Under normal conditions, the Primar y adapter handles all
non-TCP/IP trac. e Secondary adapter will receive fallback trac if the primary
fails. If the Preferred Primary adapter fails, but is later restored to an active status,
control is automatically switched back to the Preferred Primary adapter.
Step 1
From Device Manager, open the properties of a team.
Step 2
Click the Settings tab.
Step 3
Click the Modif y Team button.
Step 4
Select the adapter you want to be the primary adapter and click the Set Primary
button.
If you do not specify a preferred primary adapter, the soware will choose an
adapter of the highest capability (model and speed) to act as the default primary. If
a failover occurs, another adapter becomes the primary. e adapter will, however,
rejoin the team as a non-primary.
