3.1.3 SAS3080E and SAS3080EL HBAs Characteristics
The SAS3080E and SAS3080EL are identical HBAs with the exception
of the PCI bracket. The SAS3080E uses a standard PCI bracket and the
SAS3080EL uses a low-profile (LPPCI) PCI bracket. Figure 3.3 shows
the HBAs and their brackets.
3.1.3.1 LEDs
The SAS3080E and SAS3080EL HBAs have 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 3.3 for LED
locations.
The SAS3080E and SAS3080EL 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 LSISAS1068E heartbeat, or it turns yellow when the LSISAS1068E
firmware detects a fault condition.
3.1.3.2 Connectors
This section describes the connectors on the SAS3080E and
SAS3080EL HBAs. See Figure 3.3 for connector locations.
PCI Express Connector (J1) – The PCI Express interface has eight
PCI Express lanes, which provide possible host-side maximum
transmission and reception rates of up to 4.0-GB/s. The SAS3080E or
SAS3080EL 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 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 and J5) – The SAS3080E and
SAS3080EL support SAS connections through connectors J2 and J3.
The J2 and J3 connectors are SFF-8484 SAS internal right-angle
connectors with four sideband lines.
Activity LED Header (J6) – The connector is a 4-pin, right angle, 0.1-
inch pitch, pin header for driving external activity LEDs.
