Description

Lenovo 4XF7A99748 ThinkSystem 48U Rack Extension Kit

Overview

The Lenovo 4XF7A99748 is a 180mm rack extension kit designed for 48U ThinkSystem rack enclosures where standard depth falls short of housing deep servers, high-density storage nodes, or cable management assemblies without forcing doors closed on rear infrastructure. At 10 lb, the kit adds structural extension without meaningful load penalty, making it a practical fix for data center builds where equipment depth exceeds the stock rack interior clearance.

Compatibility

Designed for Lenovo ThinkSystem 48U rack enclosures — specifically the Onyx series. Verify your rack's base model and current depth configuration before ordering; this extension is not a universal fit across all Lenovo rack families. Confirm compatibility with your specific ThinkSystem rack model number via Lenovo's rack configurator or pre-sales engineering support before deployment.

Installation Notes

The 4XF7A99748 ships at 10 lb — factor this into rack total load calculations, particularly in high-density deployments where cumulative accessory weight against the floor-load rating matters. Country of origin is Mexico. No torque specifications, tool requirements, or environmental ratings are available in current evidence; consult the Lenovo ThinkSystem rack installation guide for your specific enclosure model before mounting.
