Disabling and enabling protocols and changing port numbers

Disabling unnecessary and unused communication protocol ports, such as SFTP, and network ports, reduces the attack surface. Changing port number default values reduces the predictability of use. See “Protocols, ports and connections" for port defaults.

Leave ION protocol enabled for configuration changes and upgrades. If ION protocol is disabled, use the display, Modbus programming or webpages to access the meter.

Required for this procedure:

  • Meter connection using ION Setup.

  • Login credentials.

  • Security configuration access privileges.

Ensure you maintain sufficient access to communicate with and configure your device.
Failure to follow these instructions can result in loss of access to the device.
  1. Open ION Setup > select the meter > Setup Assistant.
  2. Communications > Advanced Ethernet > Protocols.
  3. Change the default port number.
  4. Enable or disable the protocol.
  5. Click OK.
  6. Click Exit.
