Installing the RAID Controller
The following table describes the jumpers and the connectors on your MegaRAID SAS 9266 RAID controller.
Table 1 Jumpers and Connectors
Jumper/
Connector
Type Description
J1A2 SCS backplane management
connector 3-pin shielded header
Implements an enclosure management module that provides enclosure
management functions for storage enclosures and server backplanes.
J1A3 Local battery backup unit connector 20-pin connector
Connects the LSIiBBU09 unit directly to the RAID controller.
J1A4 SCS backplane management
connector 3-pin shielded header
Implements an enclosure management module that provides enclosure
management functions for storage enclosures and server backplanes.
J1B1 Individual PHY and drive fault
indication header
Ports 3 to 0
Ports 7 to 4
2x8-pin header
Connects to an LED that indicates whether a drive is in a fault condition. One
LED exists 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 (no SAS expanders exist).
Direct attach is defined as a maximum of one drive connected directly to
each port.
J2B4 Standard edge card connector The interface between the RAID controller and the host system.
This interface provides power to the board and an I 2 C interface connected to
the I
2
C bus for the Intelligent Platform Management Interface (IPMI).
J3A1 Drive activity LED header 2-pin connector
Connects to an LED that indicates activity on the drives connected to
the controller.
J3L1 Remote battery backup connector 20-pin connector
Connects a remote LSIiBBU09 unit to RAID controller.
J4B1 CacheVault Flash Module DDR3
interface 70-pin connector
Connects the RAID controller to the CVFM02 module. The CVFM02 unit
connects to a remote CVPM02 super-capacitor pack.
J5A1 x4 SAS Port 0 through Port 3 internal
connector SFF-8087 mini SAS 4i internal connector
Connects the controller by cable to SAS drives or SATA drives.
J5A2 Write pending LED header 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.
J5B1 x4 SAS Port 4 through Port 7 internal
connector SFF-8087 mini SAS 4i internal connector
Connects the controller by cable to SAS drives or SATA drives.
NOTE The MegaRAID SAS 9266-4i RAID controller does not contain the J5B1
connector. This connector is on the MegaRAID SAS 9266-8i RAID controller.
J6B1 Advanced Software Options
Hardware Key header 3-pin header
Enables support for the Advanced Software Options features, which include
CacheCade™, FastPath, Recovery, and SafeStore™ disk encryption.
J6B2 SBR bypass header 2-pin connector
Lets you bypass the SBR EEPROM during boot in case the EEPROM contents
are corrupt or missing.
J6B3 Global activity LED header 2-pin header
Connects to a single LED that indicates drive activity on either port.
