Lenovo 4XF7A81940 SE450 1000MM Friction Rail KIT

Lenovo 4XF7A81940 SE450 1000mm Friction Rail Kit

Overview

The Lenovo 4XF7A81940 is a 1000mm friction rail kit designed for rack-mounting the ThinkSystem SE450 edge server. Friction rails support tool-free, sliding chassis access without requiring a secondary support arm — the server stays supported by rail tension alone, which matters in shallow or mid-depth rack environments where cable management space is at a premium. At 1 lb, the 4XF7A81940 adds negligible load to the rack assembly.

Compatibility

Designed specifically for the Lenovo ThinkSystem SE450 edge server. The 1000mm rail length targets standard server rack enclosures with a usable depth of approximately 1000mm — confirm your rack's inner rail-to-rail depth before ordering, as SE450 friction rail kits are depth-specific and non-interchangeable with shorter variants. Not compatible with other ThinkSystem chassis families (e.g., SR series, SD series) or non-SE450 edge platforms.

Installation Notes

Friction rail kits rely on compression fit against the rack uprights — no screws or cage nuts are required for the rail-to-rack attachment, though chassis retention points should be verified against SE450 installation documentation. Confirm rack upright hole pattern (square, round, or threaded) is supported by the SE450 rail bracket ears before installation. Pair with appropriate rack power distribution and cable arm accessories for a complete SE450 rack deployment.
