Description of Each Part
LED Lamp (STATUS) : Turns on to indicate system operating condition.
LED Lamp (BATT ALARM) : Turns on to indicate the dropping of the lithium battery voltage (less than 2.8V).
LED Lamp (MASTER) : Turns on to indicate Master / Slave operating mode.
LED Lamp (LINK/ ACT) : Link status indication : OFF : Off-line/ON : Linked normally/Flashing : In communication
LED Lamp (1000 / 100/ 10) Data transmission speed indication : OFF : 10 Mbps/Yellow ON : 100 Mbps/Green ON: 1000 Mbps
System Initialize Switch : On default startup, set the switch to the "SYSTEM INITIALIZE" position for the power ON. Return the
11
KX-NS1000UC
switch to the "NORMAL" position when the main power switch starts to flash. On normal startup, turn the power ON with the "NOR-
MAL" position.
USB connector : Connect to external UPS, to monitor UPS power alarm status.
LAN connector : MNT/LAN/WAN. Used for maintenance and the VoIP.
MOH : External music on-hold input.
PAGING : External PAGING output. Connect to the device with the built-in amplifier.
