Introduction

This document describes the steps to replacing an additional memory card on N9K-C93180YC-FX3S.

Prerequisites

Requirements

Cisco recommends that you have knowledge of this topic:

- N9K-C93180YC-FX3S

Components Used

The information in this document is based on these software and hardware versions:

- N9K-C93180YC-FX3S

- Field Replacement Unit (FRU)

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

For some Nexus 9300 Series Switches, adding additional memory card is supported. The additional memory card is a Field Replacement Unit (FRU), it is treated as an independent part when processing RMA. The additional memory card must be removed from the old chassis to the new chassis during the chassis replacement. Similarly, you need to replace it if it is judged as a hardware failure and RMAed. As an example, this document introduces the steps of replacing additional memory card on N9K-C93180YC-FX3S.
