Table 6 MegaRAID SAS 9260CV-4i and MegaRAID SAS 9260CV-8i RAID Controllers – Jumpers and Connectors
Jumper/
Connector
Type Description
J5A1 Board-to-Board Mezzanine connector 240-pin 01 nonvolatile memory module interface
Connects the controller directly to a CVFM01 module. The
CVFM01 module connects to a remote CVPM01 module.
Refer to the MegaRAID SAS 9260CV-4i and SAS 9260CV-8i RAID
Controllers Quick Installation Guide for the procedure used to
connect a CVFM01 module to a remote CVPM01 module.
JT1A1 LED Locate and Fault Indication header
Ports 0 to 3
Ports 4 to 7
2x8-pin header
Connects to an LED array that indicates whether a drive is in
a fault condition. 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.
NOTE The MegaRAID SAS 9260CV-4i RAID controller does
not contain the JT2B1 connector, which supports ports 4 to 7.
JT1A2 LSI Internal Use header Reserved for LSI internal use.
JT1A3 SBR Firmware Recovery header 2-pin header
The SBR FW recovery header is used when SBR corruption is
suspected. Installing the jumper lets the unit boot while
bypassing the SBR information. You can then reprogram the
SEEPROM using external utility software. No jumper is
present for normal operation.
JT1A4 Serial UART header Reserved for LSI internal use.
JT1B1 SEP Enclosure Support header 3-pin header
Used for connection to the Port0 enclosure.
JT1B2 Advanced Software Options Hardware Key header 2-pin header
Enables support for the Advanced Software Options
features, which include CacheCade, FastPath, Recovery, and
SafeStore disk encryption.
JT2B1 x4 SAS Ports 4 to 7 Mini-SAS 4i Internal connector SFF-8087 x4 internal mini SAS connector
Connects the controller by cable to SAS drives or
SATA 2 drives.
NOTE The MegaRAID SAS 9260CV-4i RAID controller does
not contain the JT2B1 connector.
