3.1.2 LSISAS3442X and LSISAS3442XL Host Adapters Characteristics
The LSISAS3442X and LSISAS3442XL are the same HBA with the
exception of the PCI bracket. The LSISAS3442X uses a standard PCI
bracket and the LSISAS3442XL uses a low-profile (LPPCI) PCI bracket.
Figure 3.2 shows the HBAs and their brackets.
3.1.2.1 LEDs
The LSISAS3442X and LSISAS3442XL host adapters have eight LEDs
that turn green to indicate an activity condition on any of the eight phys.
There are eight LEDs that turn yellow to indicate a fault condition on any
of the eight phys. See
Figure 3.2 for LED locations.
The LSISAS3442X and LSISAS3442XL host adapters have two light
pipes routed through the PCI bracket. One light pipe turns green to
indicate activity on any phy. The other light pipe is bi-color. It flashes
green to indicate the LSISAS1068 heartbeat, or it turns yellow when the
LSISAS1068 firmware detects a fault condition.
3.1.2.2 Connectors
This section provides a description of the three different connectors on
the LSISAS3442X and LSISAS3442XL host adapters. See
Figure 3.2 for
connector locations.
PCI/PCI-X Connector (J1) – The PCI/PCI-X interface operates as a
32-bit or 64-bit DMA bus master. The connection is made through the
edge connector J1, which is a +3.3 V type board edge connector. The
signal definitions and pin numbers conform to the PCI/PCI-X
specifications.
SAS/SATA Connectors (J2 and J5) – The LSISAS3442X and
LSISAS3442XL support SAS connections through connectors J2 and J5.
The J5 connector is an SFF-8484 SAS internal right-angle connector
with four sideband lines. The J2 connector is an SFF-8470 SAS external
right-angle connector.
J5 contains four Serial General Purpose Input Output (SGPIO) signals.
SGPIO is a method to serialize general-purpose IO signals. SGPIO
defines the communication between an initiator (for example, a host bus
adapter) and a target (for example, a backplane holding disk drives). The
