Usually you notice nothing in your daily work. Also if you use the internal switch of the phone.
If supported by the switch, this will reduce energy consumption when there is no network traffic. Normally, you will notice no difference in your daily work, neither on the phone nor on a device (e.g. PC) connected to the phone's internal switch port.  


With one exception. Thin Client Users can loose there connection to the terminal server.
However, some switches do not support EEE properly. In such cases, you will notice spurious ''link down'' messages (e.g. in the windows ''network adapter status bubble'').  Also, some applications such as ''terminal server clients'' may drop their server connection due to the ''link down'' event.
For this case we implement from V9 hotfix 33 and V10 SR 6 an option to disable EEE - Energy Efficient Ethernet.

Ethernet link goes occasionally down when using internal switch of phones.

Applies To

This information applies to

  • all innovaphone phones with internal switch
  • V9 hotfix 33 and V10 SR6 and above (option in webgui to disable EEE)


Problem

To save power, all innovaphone phones have EEE enabled by default .

If supported by the switch, this will reduce energy consumption when there is no network traffic. Normally, you will notice no difference in your daily work, neither on the phone nor on a device (e.g. PC) connected to the phone's internal switch port.

However, some switches do not support EEE properly. In such cases, you will notice spurious link down messages (e.g. in the windows network adapter status bubble). Also, some applications such as terminal server clients may drop their server connection due to the link down event.

It is possible to disable EEE on the phone thus:
