Multi-Media Repeater

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.

When the Ring Out/Lobe Out LED is illuminated, the Token Ring
Multi-Media Repeater is connected to an active ring or lobe output.

Switches

The Reset switch reinitializes the Token Ring Multi-Media Repeater. 

The ZDL switch selects the Zero Delay Lockout feature. 

The Speed switch selects between 16 Mbps and 4 Mbps network
speed. 

Status Indicators (LEDs)

The Ring In/Lobe In LED indicates an active input connection to the
Token Ring Multi-Media Repeater. 

The Ring Out/Lobe Out LED indicates an active output connection to
the Token Ring Multi-Media Repeater. 

The Power LED monitors connection to external power.
