Serial ATA Ports
There are six Serial ATA Ports (I-
SATA0~I-SATA 5) located on the
serverboard, including four SATA2
ports and two SATA3 ports. These
ports provide serial-link signal con-
nections, which are faster than Paral-
lel ATA. See the table on the right for
pin definitions.
SAS Ports
Eight Serial Attached SCSI ports
(SAS 0~3, 4~7) provide serial link
connections. These ports are sup-
ported by an LSI 2208 ccontroller.
See the table on the right for pin
definitions.
Unit Identification Switch/LED
A Unit Identifier switch (UID) and a
rear UID LED indicator (LED3) are
located next to LAN ports on the back
of the chassis. When the user pushes
the rear UID switch, the rear UID LED
(LED3) will be turned on. Push the UID
switch again to turn off the LED indi-
cator. The UID switch provides easy
identification of a system unit that may
be in need of service. See the tables
on the right for more information.
