1
The 0.6M and 1.5M 12X cables (#1829/#1830 or #1861/#1862) have very limited use due
to their short length. They cannot be used to connect to a system drawer because of the
short length. They are intended for use between two feature 5796 or 7314-G30 drawers
mounted side by side in the same enclosure (#7314). They can also be used to connect
between two modules located one beneath the other in a 19-inch rack.

It is possible in some limited configurations to use the 3.0 M, 12X cable (#1840 or #1865)
to locate 5796 modules in adjacent racks. The cable length requires careful management of
each drawer location within the rack. The best choice for connecting a feature 5796 or G30
I/O Drawer in an adjacent rack is the 8.0 M, 12X cable (#1834 or #1864).

The 8M 12X cable (#1834 or #1864) is intended for use when connecting between two
modules that are located in adjacent racks. This cable may not be connected to the 12X
Short Run adapter (#6446).
PCI card slots
The Power 750 has a maximum of five hot-plug slots.
• Slot 1 is a PCIe x8 short-length slot. A GX++ slot shares this slot.
• Slot 2 is a PCIe x8 short-length slot. A GX+ slot shares this slot.
• Slot 3 is a PCIe x8 full-length slot.
• Slots 4 and 5 are PCI-X DDR 266 MHz full-length slots.
• All slots are hot pluggable except slots 1 and 2 when used as GX slots.
Note: Optional 12X GX+ and GX++ adapters are used for attaching I/O expansion
drawers with PCI slots and, optionally, disk/SSD bays.
Graphics adapters
• A graphics adapter, keyboard, and mouse are not required in the minimum
configuration.
• The maximum number of graphics adapters supported in the Power 750 is three.
Not supported under IBM i.
I/O adapters
• The Integrated Virtual Ethernet feature (#5613, #5623, #5624) and the SAS
RAID Enablement feature (#5679) are not plugged into a slot, leaving the slots
available for PCI adapters or GX adapters.
• Refer to Figure 2 for additional I/O adapter information.
• The adapter installed in slot 1 or 2 must be short.
• To install a GX++ adapter in the system, two or more processor cards are
required.
