Lenovo 4XF7A78616 ST50 V2 Intrusion Switch KIT

Lenovo 4XF7A78616 ST50 V2 Intrusion Switch Kit

Overview

The Lenovo 4XF7A78616 is a chassis intrusion detection kit designed specifically for the ThinkSystem ST50 V2 tower server. Intrusion switches detect unauthorized physical access — when the chassis cover is removed, the switch signals the system board, logging the event and optionally triggering alerts through the server's management firmware. For environments where physical security of server hardware is an audit or compliance requirement, this kit adds that detection capability where it is not already present from the factory. At 0.05 lb and measuring 6.70 x 4.50 x 0.60 in, 4XF7A78616 is a low-profile internal component with no external footprint.

Compatibility

This kit is designed for the Lenovo ThinkSystem ST50 V2 tower server. Verify your ST50 V2 configuration requires this kit — some factory build-outs include intrusion detection hardware at the time of order; this SKU is the field-install or add-on option for units where it was not included. It is not compatible with ST50 (Gen 1), ST250, ST550, or other ThinkSystem tower or rack form factors. Confirm compatibility against your server's server accessory options list or the Lenovo ServerProven configurator before ordering.

Installation Notes

Installation is an internal chassis procedure — the server must be powered down and the cover removed before fitting the switch. The component connects to a dedicated intrusion-detection header on the ST50 V2 system board; no external cabling or tools beyond standard server servicing practice are required. Given the 0.05 lb weight, the switch seats with light mechanical pressure — avoid forcing the connector. Retain the original chassis cover hardware to ensure the switch actuates correctly once the cover is reinstalled.
