Bootloader Installation

GigaVUE-FM supports the installation of bootloader on GigaVUE HC Series and GigaVUE TA Series nodes during the GigaVUE‑OS image upgrade, but it does not automatically activate it.

Note:  Depending on your configuration, you may need to enable physical bypass mode before performing the GigaVUE‑OS image upgrade, and then restore it after the upgrade is complete.

During the GigaVUE‑OS image upgrade, GigaVUE-FM v5.6.xx (and above) first upgrades the GigaVUE‑OS image and then reboots the system. After the GigaVUE HC Series or GigaVUE TA Series node has rebooted with the new GigaVUE‑OS image, the bootloader installation will automatically initiate from GigaVUE-FM.

Note:  The bootloader upgrade will only apply if there is a bootloader version change in the specific GigaVUE‑OS software release.

When the process completes, a message about the bootloader installation will appear in the GigaVUE-FM Task Log Details, such as, “New bootloader version may have been staged based on device bootloader version. Any future reload of device will pick the new version.” This means that the bootloader binary has been installed on the device and is ready to become active upon the next reload.

Important: The newer bootloader version only goes into effect after an additional manual reboot. You must explicitly reload the GigaVUE HC series or GigaVUE TA series device to update the bootloader version. This additional reboot will cause the optical-protection switches of relevant the Bypass Modules to change states multiple times (close > open > close > open). (Table 1 provides the list of relevant modules.) Recommendation: To avoid this state-change behavior, enable the physical bypass before performing the GigaVUE‑OS image upgrade.

Refer to"Configure Inline Bypass Examples" section in the GigaVUE-OS CLI Reference Guide for instructions on how to enable the physical bypass.
