SAS3444EL, SAS3800E, SAS3801E, SAS3801EL and SAS31601E
HBAs provide a 128K x 36-b PBSRAM memory device for storing SAS
Address Port information allowing for connection to more than 128
devices.
3.1.1 SAS3041E and SAS3041EL HBAs Characteristics
The SAS3041E and SAS3041EL are the same HBA with the exception
of the PCI bracket. The SAS3041E uses a standard PCI bracket and the
SAS3041EL uses the low-profile (LPPCI) PCI bracket. Figure 3.1 shows
the HBAs and their brackets.
3.1.1.1 LEDs
The SAS3041E and SAS3041EL HBAs have four LEDs, labeled A0–A3,
that turn green to indicate an activity condition on any of the four PHYs.
There are four LEDs, labeled LNP0–LNP3, that turn yellow to indicate a
fault condition on any of the four PHYs. See Figure 3.1 for LED locations.
The SAS3041E and SAS3041EL HBAs 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 describes the connectors on the SAS3041E and
SAS3041EL HBAs. See Figure 3.1 for connector locations.
PCI Express Connector (J1) – The PCI Express interface has four PCI
Express lanes, which provide possible host-side maximum transmission
and reception rates of up to 2.0-GB/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 SAS3041E supports
SAS/SATA connections through connectors J2 (Port 3), J5 (Port 2), J6
(Port 1), and J7 (Port 0). These connectors are SATA internal right-angle
connectors.
