F igure 6: ADAP-EVAL-QORIQ-XAUI Adapter Card LED and DIP Switch Locations
The LED0 and LED1 are off by default. See “Configuration” below for command to enable LEDs. Once enabled, the LEDs have the
following behavior:

9.2.1 PHY Infrastructure and Operation
The Broadcom BCM8707 Single Channel 10 GbE SFI-to-XAUI™ Transceiver with EDC connects the XAUI adapter Card-Edge-Con-
nector on the MAC side to the SFP+ socket on the front IO side.
After power up the transceiver loads the internal firmware and operates in autonomous XAUI to 10G mode without a specific
software driver on the host side.
As an option, the default register setting could be overridden by settings stored in the non-volatile I2C EEPROM, see “Config-
uration”.
9.2.2 DIP Switches
9.2.2.1 SFP+ Rate Select DIP Switch SW1
This DIP switch is used to configure signaling rates for SFP receiving and transmitting. The ON position of both switches is down
(meaning depressed in the direction of the adapter PCB).
STATE DESCRIPTION
Off No XAUI alignment from Host
On XAUI alignment from Host acquired
STATE DESCRIPTION
Off No line side TX or RX packets detected
On/Blinking Line side TX or RX packets detected
