Figure 1 Layout of the MegaRAID SAS 9260-8i/
9260DE-8i RAID Controller
Table 1 describes the jumpers and the connectors
on the SAS 9260 RAID controllers.
Table 1 Jumpers and Connectors
Note: JT1, JT2, and JT4 are behind the LSIiBBU07
when it is installed, but they are still accessible.
Step 4 Install the RAID Controller
Insert the RAID controller in a PCI Express slot
on the motherboard, as shown in
Figure 2 . Press
down gently, but firmly, to seat the card correctly
in the slot. Secure the RAID controller to the
computer chassis with the bracket screw.
Note: This is a PCI Express x8 card and it can operate
in x8 or x16 slots. However, some PCI-E slots
support only PCI-E graphics cards; if a RAID
controller is installed, it will not function.
Note: Refer to the guide for your motherboard for
information about the PCI Express slot.

Connector Type
Description
JT1 Write-pending Indi-
cator (dirty cache)
LED connector 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.
JT2 SAS Activity LED
header 2-pin connector
Connects to an LED that indicates
drive activity.
JT3 Battery Backup
connector 20-pin connector
Connects the LSIiBBU07 intelli-
gent Battery Backup Unit directly
to the RAID controller.
JT4 Global Drive Fault
LED header 2-pin connector
Connects to an LED that indicates
whether a drive is in a fault
condition.
JT6 x4 SAS Ports 3–0
Mini SAS 4i
connector Connects the cables from the con-
troller to SAS drives or SATA II
drives, or a SAS expander.
JT7 x4 SAS Ports 7–4
Mini SAS 4i
connector Connects the cables from the con-
troller to SAS drives or SATA II
drives, or a SAS expander.
1. The SAS 9260-4i RAID con-
troller does not have this con-
nector.
JT8 Modular RAID Key
header 2-pin connector
Reserved for LSI use.
JT9 Set Factory
Defaults connector 2-pin connector
Returns the board settings to the
defaults set in the factory.

JT12 Individual Drive
Fault LED header
for Eight Phys (0-7) 16-pin connector
Indicates drive faults. There is one
LED per port. When lit, each LED
indicates the corresponding drive
has failed or is in the Unconfig-
ured-Bad state. Refer to the
MegaRAID SAS Software User’s
Guide for more information.
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.This header is used for RAID
controllers with internal SAS ports.
JT13 Universal Asyn-
chronous Receiver/
Transmitter (UART)
debugging 4-pin connector
Reserved for LSI use.
