Description
No, you can not implement the Remote System Upgrade (RSU) configuration feature in any configuration schemes for multiple devices in a chain. This is because the internal RSU circuitry does not support reconfiguration for multiple devices in the cascaded chain. Therefore, you can only implement RSU for a single device using any configuration mode that supports the RSU feature.
For devices that support RSU feature, please refer to Table 1 in Configuration features.
Also, please refer to the respective device handbook for more information about the configuration schemes that support RSU.
