Description
2-pin connector Connects to an LED that
indicates whether a drive is in a fault
condition.
2-pin connector Connects to an LED that
indicates when the data in the cache has
yet to be written to the storage devices.
Used when the write-back feature is
enabled.
2-pin connector Reserved for factory use.
2-pin connector Connects to an LED that
indicates activity on the drives connected to
the controller.
2x8-pin header Connects to an LED that
indicates whether a drive is in a fault condi-
tion. There is one LED per port. When lit,
each LED indicates the corresponding drive
has failed or is in the Unconfigured-Bad
state. The LEDs function in a direct-attach
configuration (there are no SAS expanders).
Direct attach is defined as a maximum of
one drive connected directly to each port.
3-pin connector Supports SES (SCSI enclo-
sure services) over I2C through an internal
I2C backplane cable.
SFF-8087 mini SAS 4i internal connector
Connects the controller by cable to SAS
drives or SATA 2 drives.
SFF-8087 mini SAS 4i internal connector
Connects the controller by cable to SAS
drives or SATA 2 drives.
3-pin header Enables support for selected
advanced features, such as recovery,
Supersized cache, FastPath, and full disk
encryption.
The RAID controller interfaces with the host
system though a standard edge card. This
interface provides power to the board and
an I2C interface connected to the I2C bus
for IPMI.
4-pin connector Reserved for factory use.
