Test 7.5.5.1 - BREAK – OpenTimeout Timer SSP Target

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

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 Target):

• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence

with the DUT. Since the DUT is a target the Testing Station should transmit an Identify Address frame
indicating that it is an Edge Expander.

• The Testing Station should open an SSP connection to the DUT from another address, imitating a SAS

Initiator.

• Wait for the DUT to transmit OPEN_ACCEPT and RRDY. The Testing Station should transmit a

SCSI INQUIRY command to the DUT, then close the connection.

• Wait for the DUT to open an SSP connection to the Testing Station to the same address that sourced

the SCSI INQUIRY command.

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

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.
