Wiring Requirements ATTENTION Safety First! Be sure to disconnect the power cord before installing and/or wiring your EDS-208. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment. You should also pay attention to the following items: Use separate paths

Wiring the Power Inputs The two left-most contacts of the 3-contact terminal block connector on EDS-208’s top panel are used for both the DC and AC inputs of EDS-208. Top and front views of one of the terminal block connectors are shown here. STEP 1: Insert the negative/positive DC or AC wires into the V-/V+ terminals. STEP 2: To keep the DC or AC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connecto

RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring 100BaseFX Ethernet Port Connection The concept behind the SC/ST port and cable is quite straightforward. Suppose you are connecting devices I and II. Contrary to electrical signals, optical signals do not require a circuit in order to transmit data. Consequently, one of the optical lines is used to transmit data from device I to device II, and the other optical line is used to transmit data from device II to device I, for full-duple

Switching, Filtering, and Forwarding Each time a packet arrives at one of the switched ports, a decision is made either to filter or to forward the packet. Packets with source and destination addresses belonging to the same port segment will be filtered, constraining those packets to one port, and relieving the rest of the network from the need to process them. A packet with destination address on another port segment will be forwarded to the appropriate port, and will not be sent to the
