Using Line-Swap-Fast-Recovery
The Line-Swap Fast Recovery function, which is enabled by default, allows EDS-518A to return to normal operation extremely quickly after devices are unplugged and then re-plugged into different ports. The recovery time is on the order of a few milliseconds (compare this with standard commercial switches for which the recovery time could be on the order of several minutes). To disable the Line-Swap Fast Recovery function, or to re-enable the function after it 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:
