that port (provided this item is Enabled).

Using Line-Swap-Fast-Recovery
The Line-Swap Fast Recovery function, which is enabled by default, allows EDS-518A to return

standard commercial switches for which the recovery time could be on the order of several

has already been disabled, access either the Console utility’s Line-Swap recovery page, or the
Web Browser interface’s Line-Swap fast recovery page, as the following figure shows:
