Outlines general guidelines for replacing switch hardware in Cisco ACI environments to ensure compatibility and minimize disruption.
Follow these recommendations when performing hardware replacement to ensure compatibility and minimize traffic loss:
-
To determine which transceivers, adapters, and cables support this switch, see the Cisco Transceiver Modules Compatibility Information document.
-
To see the transceiver specifications and installation information, see Transceiver Module Installation Guides.
-
Due to potential traffic loss, it is recommended that you perform the hardware replacement during a maintenance window.
-
It is recommended to move any Cisco Application Policy Infrastructure Controllers (APICs) that are connected to the switches that you are replacing to any other switches in the fabric and wait for the Cisco APIC cluster to become "Fully Fit".
-
When the Auto Firmware Update feature is used, make sure to set the Default Firmware Version to your target version. If the node ID is part of an upgrade group, make sure that the upgrade group is set with your target version, or delete the upgrade group. See Auto Firmware Update for details.
-
The number of ports and port types of the new switches must match the old switch that you are replacing. If the number does not match, then you must change the configuration to accommodate the new ports or port types.
