Test 7.5.5.4 - BREAK – OpenTimeout Timer SMP Initiator

Purpose: To determine that the DUT, an SMP Initiator transmits BREAK after the OpenTimeout Timer expires.

7.12.2.1, 7.12.6 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 (SMP 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 Fanout 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 is 1 attached Phy. 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 SMP Phy. Close the connection.

• Wait for the DUT to open an SMP connection to the Testing Station to the same address that was

provided by the Testing Station in the DISCOVER

• The Testing Station should wait for the DUT to transmit an OpenAddress frame for an SMP

connection. The Testing Station should not respond to the OpenAddress frame with OPEN_ACCEPT
or OPEN_REJECT.

Observable Results: Verify that 1msec after transmitting the OpenAddress frame, the DUT transmitted BREAK.
