# PCIe Extender occupies a PCIe slot and is included in the NVMe PCIe SSD Upgrade Kit.
** Requires the selection of a PCIe riser card 2. If 145 W processors (E5-2697 v4 and E5-2699 v4) are selected, the ambient
temperature cannot exceed 35 °C (95 °F).
HDD Rear Kit configuration notes:
The HDD Rear Kit (00KA058) is supported only for models with 10x 2.5-inch drive bays; the HDD
Rear Kit is connected to the SAS expander on the 10-drive backplane.
The HDD Rear Kit is installed in place of the PCIe slots 1 and 2 (see I/O expansion), and it includes a
special riser that provides PCIe 3.0 x16 slot 3. No other riser cards can be used with the HDD Rear Kit.
The HDD Rear Kit is not supported in the configurations with NVMe PCIe SSDs.
145 W and 135 W processors cannot be used when the HDD Rear Kit is installed.
