3.1.2 SAS3042E and SAS3042EL HBAs Characteristics
The SAS3042E and SAS3042EL are identical HBAs with the exception
of the PCI bracket. The SAS3042E uses a standard PCI bracket and the
SAS3042EL uses a low-profile (LPPCI) PCI bracket. Figure 3.2 shows
the HBAs and their brackets.
3.1.2.1 LEDs
The SAS3042E and SAS3042EL 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 3.2 for LED locations.
The SAS3042E and SAS3042EL 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.
3.1.2.2 Connectors
This section describes the connectors on the SAS3042E and
SAS3042EL HBAs. See Figure 3.2 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 SAS3042E or
SAS3042EL 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 Connector (J5) – The SAS3042E and SAS3042EL supports
SAS connections through connector J5. The J5 connector is an SFF-
8484 SAS internal right-angle connector 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.
