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.
