This document describes the process that is used in order to determine if a Cisco Nexus 7000 Series (N7K)
M132XP−12 or a N7K−M132XP−12L module needs to be sent for Return Material Authorization (RMA).

Cisco recommends that you have knowledge of the Nexus operating system CLI.

The information in this document is based on the N7K M132XP−12 Linecard.

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, make sure
that you understand the potential impact of any command.

In the case of suspected hardware failure on the N7K−M132XP−12 module, the cause could be from a
software defect where an RMA is not required.

This document lists the symptoms experienced, and provides the troubleshooting steps required in order to
determine the health of the module.
