I2C cable connectors (connectors A and F)
– The backplane includes two 1x5 cable connectors used as a
management interface between the server board and the installed backplanes. In systems configured with
multiple backplanes, a short jumper cable is attached between backplanes, with connector A used on the
first board and connector F used on the second board, extending the SMBus to each installed backplane.

8 x 3.5” Drive Hot-Swap Backplane Overview
This section applies to the 8 x 3.5” drive hot-swap backplane (iPC – F2U8X35S3HSBP).
2U server systems that support the 8 drive backplane have support for the following drive form factors:
3.5” hard drives
2.5” SSDs using the included drive blanks as a drive bracket
Note
: Due to degraded performance and reliability concerns, the use of the 3.5” drive blank as a 2.5” drive
bracket is intended to support SSD type storage devices only. Installing a 2.5” hard disk drive into the 3.5”
drive blank cannot be supported.
This backplane has support for up to 6Gb/s SATA drives or up to 12 Gb/s SAS drives
Mounted on the front side of the backplane are eight 29-pin (SFF-8482) drive connectors. On the backside of
the backplane are connectors for power, I2C management, and SAS/SATA data.
