3.1.3 LSISAS3081E and LSISAS3081EL Host Adapters Characteristics
The LSISAS3081E and LSISAS3081EL are identical HBAs with the
exception of the PCI bracket. The LSISAS3081E uses a standard PCI
bracket and the LSISAS3081EL uses a low-profile (LPPCI) PCI bracket.
Figure 3.3 shows the HBAs and their brackets.
3.1.3.1 LEDs
The LSISAS3081E and LSISAS3081EL 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 3.3 for LED locations.
The LSISAS3081E and LSISAS3081EL 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
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 provides a description of the four different connectors on the
LSISAS3081E and LSISAS3081EL host adapters. See
Figure 3.2 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
LSISAS3081E or LSISAS3081EL 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 LSISAS3081E and
LSISAS3081EL support SAS connections through connectors J2 and J5.
The J2 and J5 connectors are SFF-8087 mini-SAS internal right-angle
connectors.
