I/O expansion options
The server supports up to seven PCIe 3.0 slots: Four slots (1 - 4) when one CPU is installed or seven slots
when two CPUs are installed. The following slot form factors are available:
Slot 1: PCIe 3.0 x8 (x8 wired); full-height, half-length
Slot 2: PCIe 3.0 x16 (x8 wired); full-height, full-length
Slot 3: PCIe 3.0 x16 (x16 wired); full-height, full-length
Slot 4: PCIe 3.0 x8 (x8 wired); full-height, full-length
Slot 5: PCIe 3.0 x8 (x8 wired); full-height, half-length (requires second processor)
Slot 6: PCIe 3.0 x16 (x16 wired); full-height, full-length (requires second processor)
Slot 7: PCIe 3.0 x16 (x16 wired) full-height, full-length (requires second processor)
Slots 3 and 6 support double-wide GPUs
The COM Port Bracket, part number 00KC332, is used for making an external serial port available at the
rear of the server. This option includes the bracket and the cable. The COM Port option is mounted in one
of the PCIe slots and that PCIe slot cannot be used. The following table lists the PCIe slot options.
