Lenovo 4XF7A99750 Thinksystem 48U Pearl 180MM Advanced Rack Extension KIT

Lenovo 4XF7A99750 ThinkSystem 48U Pearl 180mm Advanced Rack Extension Kit

Overview

The Lenovo 4XF7A99750 is a 180mm rack extension kit designed for 48U Pearl enclosures in the ThinkSystem line. Rack extension kits solve a specific physical problem: when standard rack depth is insufficient for deep servers, storage controllers, or high-density cabling configurations, the extension adds the clearance needed to mount equipment cleanly without forcing cables or stressing rear connectors. At 10 lb, this is a structural component — account for it in total rack weight calculations before installation.

Compatibility

Designed for use with the Lenovo ThinkSystem 48U Pearl rack enclosure family. Verify your specific Pearl chassis revision against Lenovo's compatibility matrix before ordering — rack extension kits are enclosure-generation specific and not universally interchangeable across Pearl variants. This kit is not a universal fit for third-party or non-Pearl Lenovo rack enclosures.

Installation Notes

Country of origin is Mexico. Installation is mechanical — no power or data connections required. Ensure the rack is unloaded or properly supported before extending the enclosure frame, as structural modifications to a loaded rack create tipping and load-distribution risks. Consult the ThinkSystem rack installation guide for torque specifications and sequencing before beginning.
