Lenovo 4TA7A70026 SR650 X16/X8(X16) PCIE FH Riser 2 KIT V2

Lenovo 4TA7A70026 SR650 Riser Kit V2

Overview

The Lenovo 4TA7A70026 is a PCIe riser kit designed for the Lenovo ThinkSystem SR650 server. This kit provides an additional two PCIe slots (one x16 physical, x8 electrical; one x8 physical, x8 electrical) to expand the server's internal expansion capabilities. It is specifically intended to accommodate additional adapter cards, such as GPUs or high-speed network interfaces, within the SR650 chassis. This riser kit is essential for configurations requiring more PCIe connectivity than the base server offers, particularly for compute-intensive tasks or specialized I/O requirements.

Compatibility

This riser kit is compatible with the Lenovo ThinkSystem SR650 server. It supports the installation of specific adapter cards, including GPUs such as NVIDIA A2, NVIDIA P600, NVIDIA P620, NVIDIA T4, and Cambricon MLU270-S4. Ensure your selected adapter cards are within the power and physical dimensions supported by the SR650 chassis and its power supply configuration when using this riser.

Installation Notes

The riser kit facilitates the installation of PCIe cards. The SR650 server supports up to 24 DIMM slots and various drive bay configurations (eight 3.5-inch, eight 2.5-inch, or sixteen 2.5-inch). For GPU installations using this riser, ensure adequate power is available: 1100-watt or 1600-watt PSUs are required for one GPU, while two or three GPUs necessitate 1600-watt PSUs. The server requires specific fan configurations: five hot-swap fans (including one redundant fan) for a single processor, and six hot-swap fans (including one redundant fan) for dual processors. The operating environment should adhere to ASHRAE Class A2 standards (8%–80% humidity, max dew point 21°C) for optimal performance.
