BLACK BOX 4-Port BNC Repeater Installation and User Guide
unplug the power cable from either the wall socket, power strip or the power connector on
the back of the unit.
When connecting various Ethernet media, there is no need to power down the
unit. Individual segments of any media type can be connected or disconnected from ports
without concern for AC power-related problems or damage to the unit.

4.3 LEDs

The 4-Port BNC Repeater is equipped with three common LEDs located on the
front of the chassis unit. These LEDs indicate Power (PWR), Jam (JAM), and Activity
(ACT). Each port has Receive(REC), Collision (COL) Partition (PAR) and Manual
Partition (MAN PAR) LEDs. The LEDs are used to provide visual indication about the
operational condition and traffic activity of the unit and its associated ports. See
Specifications for definition of each LED.
4.4 BNC Port Manual Termination Switch
The 4-Port BNC Repeater features a pushbutton switch on each BNC port that
enables that port to be isolated. This simplifies installation and repairs.
When a port is manually partitioned, devices and connections attached to it may
be tested or serviced without the risk of interfering with the operation of the other ports.
Especially for BNC networks where any
faulty connection will bring down the
network, this is useful in order to be
certain proper connections have been
made before restoring the BNC port
connection to the 4 Port BNC Repeater
unit. The manual partition function is similar to but additional to the auto-partition function
that is built in as part of the electronics of the unit.
An adjacent LED (labeled "MAN PAR") illuminates to indicate when the manual
partition is enabled.
When BNC networks are expanded and segments need to be extended or changed,
the 4-Port BNC Repeater product is ideal.
