Updating card firmware for your Encrypted Wavelength service

For security, you should periodically request firmware updates for the network cards associated with your Encrypted Wavelength service. When you request a firmware update, CenturyLink schedules it within a maintenance window to minimize the impact to your service.

Based on when your circuit was installed, your cards will have a slightly different process for updating firmware:

Circuits installed before 10/1/19

To update card firmware for your Encrypted Wavelength service:

  1. Click the Firmware Update Request tab.
  1. Type the passwords for both cards.
Important: Make sure you type the correct password for both cards. If you type the wrong password for one of the cards, the authentication key updates only on one card and prevents the cards from negotiating a new session key.
  1. In the Approved Update Firmware version field, type the firmware version you authorize CenturyLink to update your cards to, select the Update Approved checkbox, then click Submit.

    CenturyLink schedules the firmware update within a maintenance window to minimize the impact to your service.
