3.1.7 LSISAS3800E Host Adapter Characteristics
The LSISAS3800E uses a standard PCI bracket. Figure3.7 shows the
HBA and its bracket.
3.1.7.1 LEDs
The LSISAS3800E host adapter has eight LEDs, labeled A0–A7, that
turn green to indicate an activity condition on any of the eight phys.
There are eight LEDs, labeled LNP0–LNP7, that turn yellow to indicate
a fault condition on any of the eight phys. See Figure3.7 for LED
locations.
The LSISAS3800E host adapter has 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
LSISAS1068E heartbeat, or it turns yellow when the LSISAS1068E
firmware detects a fault condition.
3.1.7.2 Connectors
This section provides a description of the fourdifferent connectors on the
LSISAS3800E host adapter. See Figure3.7 for connector locations.
PCI Express Connector (J1) – The PCI Express interface has eight
PCI Express phys, which provide possible host-side maximum
transmission and reception rates of up to 4.0 Gbytes/s. The
LSISAS3800E supports x8, x4, and x1 PCI Express link widths, and
automatically downshifts if plugged into either a x4 connector or into a
x8 connector that is wired as a x4 connector. The connection is made
through the edge connector J1. The signal definitions and pin numbers
conform to the PCI Express specifications.
SAS/SATAConnectors (J2 and J3) – The LSISAS3800E supports
SAS/SATAconnections through connectors J2 and J3. The J2 and J3
connectors are SFF-8470 SAS external right-angle connectors.
Activity LED Header (J4) – 4-pin,r ight angle,0.1-inch pitch, pin header
for driving external activity LEDs.
