The EMS5-8MA-SWITCH provides
link-on and dynamic detection of cable length
and
dynamic
adjustment of power
required for the detected cable length. This feature provides high performance with
minimum power consumption.
The EMS5-8MA-SWITCH implements
link-down power saving on a per-port
basis, greatly cutting power
consumption when the network cable is disconnected. After it detects an incoming signal, it wakes up from
link-down power saving and operates in normal mode.
