How to use
Before replacing a power supply, verify compatibility with the target ThinkSystem chassis and power configuration. For hot-swap replacement, follow server manufacturer guidelines: ensure the server is in a supported state for module removal, remove the failed unit by releasing its retention latch, and slide the replacement into the bay until it seats and the latch engages. For installations involving redundant capability, install the additional module(s) and confirm the server firmware/management interface recognizes the new supply and that power-sharing and redundancy status are as expected.
Usage recommendations
Install power supplies in accordance with Lenovo service documentation and within the environmental limits of the server chassis. Use matched or approved power modules when creating redundant configurations, and verify that input voltage and rack power distribution meet the unit's 115 V/230 V requirements. For safety, perform replacements following ESD precautions and, when required, with power supplied to alternate modules to maintain system availability.
