3.1.8 SAS3801E and SAS3801EL HBAs Characteristics
The SAS3801E and SAS3801EL are the same HBA with the exception
of the PCI bracket. The SAS3801E uses a standard PCI bracket and the
SAS3801EL uses a low-profile (LPPCI) PCI bracket. Figure 3.8 shows
the HBAs and their brackets.
3.1.8.1 LEDs
The SAS3801E and SAS3801EL HBAs 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 SAS3801E and SAS3801EL HBAs 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 describes the connectors on the SAS3801E and
SAS3801EL HBAs. See Figure 3.8 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 SAS3801E or
SAS3801EL 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 SAS3801E and
SAS3801EL support SAS connections through connectors J2 and J3.
These connectors are SFF-8088 mini-SAS external right-angle
connectors.
Activity LED Header (J4) – The connector is a 4-pin, right angle, 0.1-
inch pitch, pin header for driving external activity LEDs.
