Connectors
The different HBA connectors are listed in the following table
(see Figure 17 for connector locations).
Table 4 HBA Connectors
|
|
PCI Express Connector (J1) |
The HBA supports an x8 interface. The
PCI Express connection is through the edge connector, J1, which
provides connections on both the top (J1B) and bottom (J1A) of the
board. The signal definitions and pin numbers conform to the PCI
Express specifications. |
UART Connector (J3) |
Debug port requiring a special cable
and support to gather detailed IOC status. |
SAS/SATA Connectors (J7 and J8) |
The HBA supports SAS connections through
connectors J7 and J8. These connectors are SFF-8087 mini-SAS, internal,
right-angle connectors. |
Activity LED Header (J6) |
4-pin, right-angle, 0.1-in. pitch, pin
header for driving external activity LEDs |
