Lenovo 4M17A13564 SR250/SR150 Toolless Friction Rail

Lenovo 4M17A13564 SR250/SR150 Toolless Friction Rail

Overview

The Lenovo 4M17A13564 is a toolless friction rail designed for the ThinkSystem SR250 and SR150 1U rack servers. At 32.90 inches deep and weighing 4.60 lb, this rail slides into standard EIA-310 rack columns without requiring loose hardware during installation — the friction-retention mechanism holds the rail in position while you seat the chassis, which matters when you're racking a server without a second pair of hands. If you're building out a dense edge compute stack or a compact surveillance back-end and need clean, repeatable 1U installations, the 4M17A13564 is the correct rail for these two platforms.

Key Features

• Toolless Installation: The friction-retention design eliminates screws during rail mounting. This cuts per-server rack time meaningfully in multi-unit deployments — no dropped hardware, no stripped threads in the rail flange.
• SR250 and SR150 Compatibility: Engineered specifically for the ThinkSystem SR250 and SR150 chassis geometry. Using a non-matched rail on a 1U server risks chassis flex, poor slide action, and voided support — this is the matched-fit option for these platforms.
• 32.90-Inch Rail Depth: At 32.90 in (2.74 ft) of usable depth, the 4M17A13564 accommodates standard 4-post racks in most data center and IDF/MDF closet configurations. Verify your rack's usable depth before ordering if you're working with shallow-depth enclosures under 30 in.
• 4.60 lb Rail Weight: Light enough for single-technician handling during install, with enough structural mass to provide stable chassis support under the SR250's loaded weight.

Integration & Compatibility

The 4M17A13564 is confirmed for the Lenovo ThinkSystem SR150 and SR250 server platforms. It is not a universal rail — do not attempt to fit it to other ThinkSystem generations or third-party chassis without verifying rail-to-chassis mounting geometry. For broader server rack accessories or to explore the full Lenovo server and infrastructure catalog, including compatible rack enclosures and power distribution units, confirm platform generation before adding to your rack BOM.

Frequently Asked Questions

Q: Which server models is the 4M17A13564 compatible with?

A: The 4M17A13564 is designed for the Lenovo ThinkSystem SR250 and SR150 1U rack servers. It is not a universal rail and should not be used with other server platforms without verifying mechanical fit.

Q: Does installation require tools?

A: No. The 4M17A13564 uses a toolless friction-retention mechanism, allowing the rail to be mounted in standard rack columns without screws or additional hardware during the rail-seating step.

Q: What rack depth does the 4M17A13564 support?

A: The rail measures 32.90 inches in length. Verify your rack's usable interior depth before ordering — shallow-depth enclosures under approximately 30 inches may not accommodate this rail.

Q: How much does the 4M17A13564 weigh?

A: The rail weighs 4.60 lb, making it manageable for a single technician during installation.

Q: Is this a single rail or a pair?

A: The evidence on file covers the 4M17A13564 as a single kit unit. Confirm quantity with your order to ensure you receive the correct number of rails for a full server installation.

Karl Wilson

The 4M17A13564 is a straightforward platform-matched rail — but 'straightforward' only holds if you're installing it on the right chassis. At 32.90 inches deep, it fits the overwhelming majority of 4-post data center racks; where integrators run into trouble is in edge deployments with shallow-depth network cabinets (24–28 in interior depth), where this rail physically will not seat. Confirm rack interior depth before it ships to the site.

Technical Highlights:

• 32.90 in Rail Length: Covers standard 4-post rack depths for most IDF, MDF, and data center configurations — but incompatible with shallow-depth edge cabinets under ~30 in usable depth.
• Toolless Friction Design: Eliminates loose hardware at the rail-mounting step, reducing per-server install time and the risk of dropped screws inside a populated rack during a live deployment window.
• 4.60 lb Unit Weight: Light enough for single-technician handling — relevant when you're racking SR250 units in a remote edge closet without a full install crew.

Deployment Considerations:

• Confirm rack usable depth before ordering. The 32.90 in rail length requires adequate clearance in both front and rear rail-mounting positions — a common miss on APC AR3100 and similar 29.5 in usable-depth two-post open-frame racks.
• This rail is platform-specific to the SR150 and SR250. It will not transfer to SR630, SR650, or other ThinkSystem generations — order by server model, not by rack U-position.

The 4M17A13564 is the right call for SR250-based edge surveillance back-end builds — compact NVR or VMS server installations in IDF closets where clean 1U racking and minimal install time per node matter more than flexibility.
