Powering the LH8050A
The LH8050A incorporates an internal universal power supply, and has a male IEC
connector for the AC power cord at the right-rear. A six foot 115vac power cord is supplied
with each unit. (Units shipped from the Black Box to outside the United States and Canada will
not include a 115vac power cord.)
The LH8050A supports installation environments where the AC voltage ranges from
90 - 260 volts with a power input frequency of between 47 - 63 Hz and will consume no more
than a maximum of 30 watts. The power connector is located on the back of the unit. In order
to power down the unit, simply unplug the unit’s power cable In a stacked configuration, this
will NOT affect the operation of other units in the stack. When connecting various Ethernet
media, there is no need to power down the LH8050A unit. Individual segments of any media
type can be connected or disconnected from PMs without concern for AC power -related
problems or damage to the unit.
