F THE DUAL SOURCE DESIGN a The Switch unit can receive power from either input A or B The hub will normally draw its power from the DC source with the highest voltage at a given time b The Switch unit will not allow power to flow from a higher voltage input to a lower voltage input i e the two DC power sources are not mixed together by the hub c When one correct DC input is present the Switch will receive power if the other DC input is absent or even if it is connected with reverse polarity or shorted or grounded d Reverse polarity connections if they should accidentally occur on either input will not damage the Switch or power supply internally nor will it blow the fuse in the internal power supply because of the blocking action of the diodes This is true even if one input connection is reversed while the Switch is operating from the other source e The Switch will not receive power and will not work when both inputs are simultaneously absent or are both incorrectly connected C5 0 INSTALLATION This section describes the proper connection of the 48VDC 24VDC amp 125VDC dual source leads to the 48 VDC 24VDC and 125VDC power terminal block on the Magnum 4K Series Switch shown in Figure The 48VDC terminal block on the Magnum 4K Series Switch is located on the right rear of the unit and is equipped with five 5 screw down lead posts see Fig C5 0 The primary terminals are identified as positive A nega

Fixed full duplex mode the 4K16 Switch s RJ 45 ports will default to operate at half duplex 4 6 Flow control IEEE 802 3x standard Magnum 4K Series Switches incorporate a flow control mechanism for Full Duplex mode The purpose of flow control is to reduce the risk of data loss if a long burst of activity causes the switch to save frames until its buffer memory is full This is most likely to occur when data is moving from a 100Mb port to a 10 Mb port and the speed difference makes the 10Mb port unable to keep up It can also occur when multiple 100Mb ports are attempting to transmit to one 100Mb port and in other protracted heavy traffic situations Magnum 4K Series Fiber Switches implement the 802 3x flow control non blocking on Full Duplex ports which provides for a PAUSE packet to be transmitted to the sender when the packet buffer is nearly filled and there is danger of lost packets The transmitting device is commanded to stop transmitting into the switched port for sufficient time to let the Switch reduce the buffer space used When the available free buffer queue increases the Switch will send a RESUME packet to indicate the transmitter to start sending the packets Of course the transmitting device must also support the 802 3x flow control standard in order to communicate properly during normal operation Note When in Half Duplex mode the 4K16 switch implements a back pressure algorithm on 10 100 Mb ports for fl
