A.2 Connector Pinouts

The AMC.1-HDD SAS disk includes an AMC connector, which conforms to the single-slot B+ extended connector, with 170 signal contacts.

The AMC.1-HDD SAS disk communicates with the carrier board through the AMC connectors. Connector usage for the AMC.1-HDD SAS disk is listed in the following table.

A.3 SAS Controller Ports

The AMC.1-HDD SAS disk incorporates four dedicated SAS controller ports as follows.

TABLE A-2
SAS Controller Port | Dedicated Function
0 | Routes to the onboard SAS disk drive, primary port A
1 (See Note) | Routes to AMC channel 2 (connects to SAS or SATA disk)
2(See Note) | Routes to AMC channel 3 (connects to SAS or SATA disk)
3 | No Connect

These SAS ports are shipped with PHY’s disabled and are not driving AMC ports 2 and 3. This default configuration avoids incompatibilities with systems that have other initiators driving these AMC ports.

##

A.4 e-Keying Ports

The AMC.1-HDD SAS disk connects up to two SAS ports on the AMC connector. These ports are defined by the AMC.3 specification for serial storage. The module designates four PCI Express ports, per AMC.1 specification. The link type and link type extension are defined in the following table.

TABLE 0-1 AMC e-Keying Port Assignments
Port # | Port Name | Link Type | AMC Port Map Region
--- | --- | --- | ---
0 | Unused |  |
1 | Unused |  |
2 | Channel 0 | Link type 7 = AMC.3 storage, Link type extension = 2 (SAS and SATA) AMC asymmetric match = 00b (SAS) | Common options
3 | Channel 1 | Link type 7 = AMC.3 storage, Link type extension = 2 (SAS and SATA) AMC asymmetric match = 00b (SAS) | Common options
4-7 | Channel 2 | Link type 2 = AMC.1 PCI Express typ e = 4 | Common options
4 | Channel 3 | Like type 2 = AMC.1 PCI Express type 1 |
8-20 | Unused |  |
