3-14 Host Adapter Characteristics

3.1.7 LSISAS3800E Host Adapter Characteristics

The LSISAS3800E uses a standard PCI bracket. Figure 3.7 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 Figure 3.7 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 four different connectors on the

LSISAS3800E host adapter. See Figure 3.7 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/SATA Connectors (J2 and J3) – The LSISAS3800E supports

SAS/SATA connections through connectors J2 and J3. The J2 and J3

connectors are SFF-8470 SAS external right-angle connectors.

Activity LED Header (J4) – 4-pin, right angle, 0.1-inch pitch, pin header

for driving external activity LEDs.
