USING LANVIEW Receive (RECEIVE) This yellow LED flashes when the repeater port receives data from the network. The LED flash is pulse stretched for viewing effect. Collision (COLLISION) This red LED flashes when the repeater port detects a collision condition or a jabber packet on the network. The flash frequency may increase as network traffic increases since more collisions are likely to occur.
POWER SUPPLY CORD The mains cord used with this equipment must be a 2 conductor plus ground type with minimum 0.75 mm square conductors and must incorporate a standard IEC appliance coupler on one end and a mains plug on the other end which is suitable for the use and application of the product and that is approved for use in the country of application.
