3.1.4 LSISAS3442E and LSISAS3442EL Host Adapters Characteristics
The LSISAS3442E and LSISAS3442EL are the same HBA with the
exception of the PCI bracket. The LSISAS3442E uses a standard PCI
bracket and the LSISAS3442EL uses a low-profile (LPPCI) PCI bracket.
Figure 3.4 shows the HBAs and their brackets.
3.1.4.1 LEDs
The LSISAS3442E and LSISAS3442EL host adapters 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 3.4 for LED locations.
The LSISAS3442E and LSISAS3442EL host adapters 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
greento indicate the LSISAS1068E hear tbeat, or it turns yellow when the
LSISAS1068E firmware detects a fault condition.
3.1.4.2 Connectors
This section provides a description of the fourdifferent connectors on the
LSISAS3442E and LSISAS3442EL host adapters. See Figure 3.4 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
LSISAS3442E or LSISAS3442EL 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 J5) – The LSISAS3442E and
LSISAS3442EL support SAS connections through connectors J2 and J5.
The J5 connector is an SFF-8484 SAS internal right-angle connector
with four sideband lines. The J2 connectoris an SFF-8470 SAS external
right-angle connector.
