PCIe Flash Storage Adapters
The server supports the PCIe Flash Storage adapters listed in the following table.
Note: The server supports a maximum quantity of three of the full-height adapters, which must be installed
in slots 1, 2, and 3. These slots require the second processor and the 3-slot riser card, 88Y7371.

* These modular adapters are not available through CTO or Special build. The adapter cannot be shipped
installed and instead must be shipped in its option box and configured at the final installation location.

Power supplies
The server supports up to two redundant power supplies. Standard models come with one or two 900 W
power supplies (model dependent; see
Standard models
). 1400 W AC and 750 W DC power supplies also
available through CTO or Special Bid.
Installing a second power supply requires that the processor and memory expansion tray (88Y7365) or the
power interposer card (88Y7367) be installed. The power interposer card option enables redundancy power
support when the processor and memory expansion tray is not installed. If you do not have the processor
and memory expansion tray installed and want to install two power supplies, then the power interposer
card must be installed.

* The power interposer is not needed if the processor and memory expansion tray (88Y7365) is installed.
Each AC power supply ships standard with one 2.8 m C13 - C14 power cord.
Two installed power supplies form a redundant pair. Under extreme configurations, with two 1400 W
supplies installed, it might still be possible to exceed 1400 W DC output. If this condition exists and a
power supply fails, the server caps power at 1400 W until the second power supply is back online.
