Lenovo 4M27A11826 SR850 V2 Intrusion Detection Kit

Overview

The Lenovo 4M27A11826 is a physical intrusion detection kit designed for the ThinkSystem SR850 V2 rack server platform. It enables chassis-intrusion alerting — notifying system administrators when the server cover is removed, a critical physical security control in data center and co-location environments where unauthorized internal access must be logged or alarmed. This is a factory-new, genuine Lenovo spare/option kit, not an aftermarket substitute.

Compatibility

The 4M27A11826 is designed for the Lenovo ThinkSystem SR850 V2 platform. Verify chassis generation before ordering — SR850 and SR850 V2 are distinct platforms with different internal bay and connector layouts; this kit is not confirmed compatible with first-generation SR850 or other ThinkSystem 2U/4U models. Cross-reference against Lenovo's SR850 V2 Hardware Maintenance Manual or the server's options compatibility matrix to confirm fit for your specific chassis configuration.
