LSISAS3442EL, LSISAS3443E, LSISAS3443EL, LSISAS3444E,
LSISAS3444EL, LSISAS3800E, LSISAS3801E, and LSISAS3801EL
host adapters provide a 128 K x 36-bit PBSRAM memory device for
storing SAS Address Port information allowing for connection to more
than 128 devices.
3.1.1 LSISAS3041E and LSISAS3041EL Host Adapters Characteristics
The LSISAS3041E and LSISAS3041EL are the same HBA with the
exception of the PCI bracket. The LSISAS3041E uses a standard PCI
bracket and the LSISAS3041EL uses the low-profile (LPPCI) PCI
bracket.
Figure 3.1 shows the HBAs and their brackets.
3.1.1.1 LEDs
The LSISAS3041E and LSISAS3041EL host adapters have four LEDs,
labeled A0–A3, that turn green to indicate an activity condition on any of
the eight phys. There are eight LEDs, labeled LNP0–LNP3, that turn
yellow to indicate a fault condition on any of the eight phys. See
Figure 3.1 for LED locations.
The LSISAS3041E and LSISAS3041EL 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 LSISAS1064E heartbeat, or it turns yellow when the
LSISAS1064E firmware detects a fault condition.
3.1.1.2 Connectors
This section provides a description of the five different connectors on the
LSISAS3041E and LSISAS3041EL host adapters. See
Figure 3.1 for
connector locations.
PCI Express Connector (J1) – The PCI Express interface has four PCI
Express phys, which provide possible host-side maximum transmission
and reception rates of up to 2.0 Gbytes/s. The PCI Express connection
is made through the edge connector J1. The signal definitions and pin
numbers conform to the PCI Express specifications.
SAS/SATA Connectors (J2, J5–J7) – The LSISAS3041E supports
SAS/SATA connections through connectors J2, J5, J6, and J7. These
connectors are SATA internal right-angle connectors.
