Transition Networks 1004 Operation, Site Considerations, Monitoring Power LED, Model

4. OPERATION

The Model 1004 Repeater Hub requires no intervention beyond occasionally monitoring the Power and Status LEDs.

Monitoring Power LED

The green Power LED is illuminated when the Model 1004 Repeater Hub is connected to power.

Monitoring Status LEDs

The green Link LED blinks, indicating a partition condition, when the Model 1004 Repeater Hub port registers sixty-four consecutive collisions.

The green Link LED is illuminated a good port link has been achieved.

The green Receive LED is illuminated continuously when the Model 1004 Repeater Hub port registers packets received.

2. SITE CONSIDERATIONS

The site for the Model 1004 Repeater Hub must provide:

•AC power outlet for each Model 1004 Repeater Hub

•Adequate ventilation

•Standard environmental conditions

•Isolation from electrical noise, including radio transmitters and broadband amplifiers, motors, high power electrical lines, or fluorescent light fixtures.

Additionally:

•The twisted pair cables should not run in the same conduit with power line cables.

•Phone lines should be separated from data cables.

•Flat or “silver satin” wires should not be used.

•RJ-45 connected cables should be configured as crossover or straight through according to installation requirements.

And:

•Since the Model 1004 Repeater Hub is an Ethernet repeater, the entire installation should comply with the IEEE Ethernet 802.3 specification

•RJ-45 connected cables should be configured as crossover or straight through according to installation requirements.
