The Lenovo accessory set with manufacturer number 4XH7A82896 is a specific riser option kit for use in rack systems. It is designed for the ThinkSystem V3 2U server platform and serves to extend the PCIe slots within the housing. The set enables the installation of PCIe cards in a 2U rack server, with the configuration set for an x16/x8/x8 distribution. The designation Riser 1/2 Option Kit refers to the support of two riser positions, where the first position provides an x16 slot and the second position provides two x8 slots. This configuration is typical for servers requiring a combination of high-performance graphics cards, network adapters, or storage expansions.

Rack systems are standard in data centers and server rooms, as they enable structured, space-saving, and cable-organized mounting of servers and network devices. The accessory set is specifically designed for use in such environments and adapts to the mechanical and electrical requirements of the ThinkSystem V3 2U model. Compatibility with this server model ensures secure mechanical fixation and correct electrical connection of the installed PCIe cards.

Accessory set refers here to a pre-configured collection of components that belong together to fulfill a specific function. In the case of Lenovo 4XH7A82896, the set includes a 3FH riser cage, a PCIe Gen4 riser card with x16/x8/x8 configuration, two M3.5 screws, and two PCIe labels (for positions 1–3 and 4–6). These labels serve to identify the slots and facilitate management and maintenance of the installed cards. The riser card itself is designed for PCIe Generation 4 (Gen4), enabling a data transfer rate of up to 16 GT/s per lane, thus providing high bandwidth for demanding applications such as virtualization, data analysis, or high-performance computing.

PCIe-Gen4 is an interface technology used in modern servers and workstations to connect expansion cards to the main system. Gen4 technology offers double the bandwidth per lane compared to previous generations, which is particularly beneficial for applications with high data throughput. The x16/x8/x8 configuration allows one card to operate at full bandwidth (x16) and two additional cards at half bandwidth (x8) simultaneously, ensuring flexible utilization of available resources.

Compatibility is a central feature of this accessory set. It is exclusively intended for the ThinkSystem V3 2U server, with mechanical fit and electrical interface tailored to this model. Use in other server models is not intended and may lead to malfunctions or damage. The riser card and riser cage are dimensioned to securely fit in the designated mounting positions of the server and comply with required cooling and ventilation specifications.

Multicolored describes the coloration of the components. As this is a technical accessory set, the coloration is functional, not decorative. Individual parts may have different colors to visually distinguish different functions or mounting positions. This facilitates installation and maintenance, especially in environments with multiple identical servers.

Installation is performed by securing the riser cage in the server housing using the included M3.5 screws. The riser card is inserted into the cage, and then the PCIe cards are plugged into the corresponding slots. The labels serve as visual aids to clearly identify the card positions.

In operation, the accessory set enables flexible server functionality expansion through the integration of PCIe cards. Gen4 support ensures high data transfer performance required for modern applications. The mechanical stability of the riser cage ensures secure fixation of the cards, which is particularly important under vibrations or mechanical stress in data centers. The combination of x16/x8/x8 slots offers balanced utilization of available bandwidth, allowing both high-performance single cards and multiple medium-sized cards to be operated simultaneously.

ThinkSystem V3 2U is the specific server model for which this accessory set was developed. It is a 2U rack server mounted in standard rack systems. The 2U designation refers to the server's height in rack units (1U = 1.75 inches), enabling compact placement in server racks. Using the accessory set extends the functionality of this server without altering its base configuration.

The accessory set is thus a specific, compatible expansion module for the ThinkSystem V3 2U server, enabling the installation of PCIe cards in an x16/x8/x8 configuration. The use of PCIe Gen4 technology ensures high bandwidth, while the mechanical design guarantees secure mounting and operational reliability in rack environments. The included labels support management of installed cards, simplifying maintenance and fault diagnosis.
