3.1.8 LSISAS3801E and LSISAS3801EL Host Adapters Characteristics
The LSISAS3801E and LSISAS3801EL are the same HBA with the
exception of the PCI bracket. The LSISAS3801E uses a standard PCI
bracket and the LSISAS3801EL uses a low-profile (LPPCI) PCI bracket.
Figure 3.8 shows the HBAs and their brackets.
3.1.8.1 LEDs
The LSISAS3801E and LSISAS3801EL host adapters have eight LEDs,
labeled A0–A7, that turn green to indicate an activity condition on any of
the eight phys. There are also eight LEDs, labeled LNP0–LNP7, that turn
yellow to indicate a fault condition on any of the eight phys. See
Figure 3.8 for LED locations.
The LSISAS3801E and LSISAS3801EL host adapters contain two
additional LEDs. One LED turns green to indicate activity on any phy.
The other LED is bi-color. It flashes green to indicate the LSISAS1068E
heartbeat, or it turns yellow when the LSISAS1068E firmware detects a
fault condition.
3.1.8.2 Connectors
This section provides a description of the four different types of
connectors on the LSISAS3801E and LSISAS3801EL host adapters.
See
Figure 3.8 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
LSISAS3801E or LSISAS3801EL 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 LSISAS3801E and
LSISAS3801EL support SAS connections through connectors J2 and J3.
These connectors are SFF-8088 mini-SAS external right-angle
connectors.
