Page 7: Operation
4. OPERATION The Multi-Media Repeater requires no intervention beyond occasionally monitoring the Power and Status LEDs. Monitoring Power LED When the green Power LED is illuminated, the Token Ring Multi- Media Repeater is connected to power. Monitoring Status LEDs When the Ring In/Lobe In LED is illuminated, the Token Ring Multi- Media Repeater is connected to an active ring or lobe input. -
Page 8: Site Considerations
2. SITE CONSIDERATIONS The site for the Token Ring Multi-Media Repeater must provide: • AC power outlet for each Token Ring Multi-Media Repeater • Adequate ventilation • Standard environmental conditions • Isolation from electrical noise, including radio transmitters and broadband amplifiers, motors, high power electrical lines, or fluorescent light fixtures. -
