  • Repeat BOOTP request after new start
    If BOOTP/DHCP is not explicitly required,
    we recommend deactivating it via the Telnet
    configuration before the firmware update.
  • Deactivation of the BOOTP client simultaneously
    switches off the RARP protocol too.
  • In addition to the standard gateway, up to four fixed routes can be configured via Telnet
  • Optimized inventorying with WuTility
