Specifications

SATA-IO Confidential 37
• This requirement must be verified on 10 total sequences of PMREQ_P, if supported and 10 total sequences
of PMREQ_S, if supported.
• A sequence fails if there is no response (i.e. no PMACK or PMNAK is returned) or if the interface rate
changes from before to after the power management sequence.
Pass/Fail Criteria
• To report a single pass/fail result for all sequences, the following pass/fail rules apply:
1. If 1 or more of the sequences fails, the result is Fail.
2. If 1 or more of the sequences pass and none fail, the result is Pass.
3. If all the sequences result with PMNAKs and no pass or fail sequences, the result is NA.
2.6. Mechanical - Cable Assembly - Standard Internal and eSATA
If both ends of a cable have identical connector types, then the mechanical tests will only need to be verified on one
end of the cable.
The tester shall ensure that the cable assemblies are clearly labeled so that each line in a cable assembly can be
uniquely identified. For a standard internal cable assembly, a suggested labeling method is:
• Each of the cables is labeled
• The two ends of the cable are also labeled, e.g. Recept_A, Recept_B
• The signal lines use the pin names provided in the specification. For standard internal connectors table 2 and
Figure 29 of section 6.1.3.2, in the Serial ATA Revision 2.6 specification labels the individual signal lines as
S1, S2, S3, …S6, S7. It also defines Pair A as being the combination of signal lines S2 and S3, while Pair B
is defined as the combination of signal lines S5 and S6.
If a family of cables is being tested, all tests shall be performed on only one of the cables (longest or shortest).
To ensure that tests are executed in an order to minimize impact between results gathered for the different tests, the
following considerations are necessary for executing the mechanical cable tests.
• All SI (electrical tests) must be completed on a cable sample prior to any mechanical tests
• For internal SATA cables the cable sample used to verify MCI-02, MCI-03, MCI-04 shall be a different
physical sample from which is used to verify MCI-01 and MCX-05
• For eSATA cables the samples used for MCE-01 and MCX-05 should the same sample.

2.6.1.1. Cable Assembly Expected Behavior
See section 6.1.10.2, Table 5 of the Serial ATA Revision 2.6 specification.
See section 6.1.10.2, Table 6 and section 6.1.4, Figures 30 and 31 of the Serial ATA Revision 2.6 specification.
Measurement Requirements
This test is only applicable to standard internal (latching and non-latching) SATA cables.
• NOTE : all applicable measurements within this test must be verified as a pass for the overall result of this
test requirement to be reported as a PASS.
Pass/Fail Criteria
• The height of the slot (for the device plug tongue) shall be 1.40 +/- 0.08 mm (Figure 30, section A-A).
• The width of the slot (for the device plug tongue) shall be 10.57 +/- 0.08 mm (Figure 30).
• The height of the slot for the device plug key shall be 2.40 +/- 0.08 mm (Figure 30).
• The width of the slot for the device plug key shall be 1.31 +/- 0.05 mm (Figure 30).
• For a non-latching cable the width of the cable retention feature (bump) shall be 1.50 +/- 0.20 mm (Figure 30).
• For a latching cable there shall be no cable retention feature (bump), as shown in Figure 31.
• For a latching cable the distance from the slot to the top surface of the receptacle shall be 1.45 +/- 0.05 mm
(Figure 31).
