Test 7.5.1.2 - Connections through Expanders – OPEN SSP Initiator
Purpose: To determine that the DUT, an SSP Initiator, can properly open a connection through an expander to
transmit data or command frames.

7.12.1 SAS Standard
Resource Requirements: SAS Protocol Analyzer and Generator
Revision History: September 13, 2004
Test Setup: The DUT and the Testing Station are physically connected.
Test Procedure (SSP Initiator):
• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence
with the DUT. Since the DUT is an initiator the Testing Station should transmit an Identify Address
frame indicating that it is an Edge Expander.
• Wait for the DUT to open an SMP Connection to the Testing Station. Allow the DUT to transmit a
REPORT_GENERAL SMP Request. The Testing Station should respond on the same connection with
a REPORT_GENERAL SMP Response indicating that there are 2 attached Phys. One of these phys
will simulate an attached SSP target. The other phy will represent the phy that the DUT is attached to.
When the response is complete close the connection.
• Wait for the DUT to open an SMP Connection to the Testing Station. Allow the DUT to transmit a
DISCOVER SMP Request. The Testing Station should respond on the same connection with a
DISCOVER SMP Response providing a SAS address of one attached SSP Phy. Close the connection.
• Wait for the DUT to open an SSP connection to the Testing Station to the same address that was
provided by the Testing Station in the DISCOVER
• Before transmitting OPEN_ACCEPT the Testing Station should transmit AIP(NORMAL) followed by
AIP(WAITING ON DEVICE)
• Allow the DUT to transmit a SCSI Command frame to the Testing Station.
• When the DUT transmits CLOSE (NORMAL) to close the connection, the Testing Station should
transmit CLOSE (NORMAL) in response.
Observable Results: Verify that the DUT successfully transmitted the SCSI Command frame.
