Explains how to upgrade firmware for P-LTE-450 MHz and Wi-Fi modules using the SD-WAN Manager. This process ensures devices maintain optimal performance through systematic firmware updates and status tracking.
Minimum supported release: Cisco Catalyst SD-WAN Manager Release 20.18.1 and Cisco IOS XE Catalyst SD-WAN Release 17.18.1a
Starting from Cisco Catalyst SD-WAN Manager Release 20.18.1 , the following module firmware upgrades are supported:
-
P-LTE-450 MHz module
-
Wi-Fi module
Summary
The module firmware upgrade process involves a sequence of actions between the SD-WAN Manager, remote server, and devices.
-
SD-WAN Manager: Sends instructions to devices and provides real-time status updates.
-
Devices: Perform pre-checks, download, validate, and install the firmware.
The process allows you to monitor and confirm the completion of the upgrade across all selected devices.
Workflow
-
Identify device or module: Identify the device or module that requires a firmware upgrade. Cisco SD-WAN Manager displays the list of devices that are eligible for firmware upgrade. Each of these devices have either a Wi-Fi module, P-LTE-450 MHz module, or a cellular modem or a combination of these.
Before you proceed with upgrading the firmware for the module, make a note of which devices to upgrade. This is an important step because firmware upgrade is done in a specific order. For more information, see Order of firmware upgrade .
-
Download firmware files: Download the firmware files for the Wi-Fi module from Cisco Software Central. All the firmware files are hosted on Cisco Software Central . After identifying the device to be upgraded, search and download the specific firmware software.
Download the firmware files for the P-LTE-450 MHz module from the Intelliport product website. For any assistance, contact the Intelliport representatives. You can download the Pluggable Interface Module (PIM) firmware or modem firmware or both.
Save the downloaded firmware upgrade files to a file server accessible by devices in the network.
-
Configure a remote server to host the firmware image: The P-LTE-450 PIM has an integrated modem, which is a core component for establishing and managing the connection to the LTE 450 MHz mobile networks. The firmware upgrade of P-LTE-450 module includes upgrading the PIM firmware and the modem firmware.
There are two phases in the P-LTE-450 firmware upgrade process, each using a separate firmware file. The sequence of upgrade is as follows:
-
Modem firmware is upgraded first
-
PIM firmware is upgraded next
You can also upgrade the modem firmware and PIM firmware separately. If the firmware upgrade fails either for PIM or modem, an error message with error details appears on Cisco SD-WAN Manager .
To configure remote file server for firmware upgrade, refer to Configure a remote file server for firmware upgrade images .
-
-
Understand the order of upgrading firmware: The firmware upgrade process follows a specific order of precedence based on the firmware files present on the remote server. For more information, see Order of firmware upgrade .
-
Start or Schedule the firmware upgrade: Use the firmware upgrade workflow in Cisco SD-WAN Manager . You can start the upgrade right away or schedule it for a specific time, for example to coincide with a maintenance window. For more information, refer to Upgrade the firmware for P-LTE-450 MHz or Wi-Fi modules .
-
Processing upgrade: Cisco SD-WAN Manager sends an upgrade request, including server details and the firmware path, to each device for the modules requiring an upgrade. Each device verifies the files, then downloads and installs the firmware either at the scheduled time or immediately.
-
Track progress: Use Cisco SD-WAN Manager to monitor the status of your firmware upgrades.
-
Upgrade execution: After verification, the P-LTE-450 MHz or the Wi-Fi module firmware is upgraded.
-
Verify the firmware upgrade: After the upgrade, verify that the devices have successfully updated to the new firmware version. For more information, refer to View the status of a cellular modem firmware upgrade .
