Idle timeout
By default, the Web‑based Manager disconnects administrative sessions if no activity takes place for fifteen minutes. This idle timeout is recommended to prevent someone from using the Web‑based Manager from a PC that is logged in and then left unattended.
To change the Web‑based Manager idle timeout:
1. Go to System Settings > Admin > Admin Settings.
2. Change the Idle Timeout minutes as required.
3. Select OK
