Connectors and Indicators

CONNECTORS

Eight (8) straight-through RJ-45 connectors, labeled 1-8, and one (1)
crossover RJ-45 connector, labeled X, are located on the front of the
LANMaster T8.

One (1) AUI connector, one (1) BNC connector, and one (1) AC
power supply adapter connector are located on the back of the
LANMaster T8.

LED INDICATORS

Steady green Act(ivity) LED
indicates connection of the
LANMaster T8 to external AC
powerr. Blinking green
Act(ivity) LED indicate
network traffic.

Steady green Link Status
LEDs 
indicate (for each port)
the integrity of the network
link at the RJ-45 connector.
Blinking green Link/Receive
LEDs 
indicate (for each port)
reception of valid data. 

5. MAINTENANCE

WARNING: DO NOT, UNDER ANY CIRCUMSTANCES, open
and attempt to repair the LANMaster T8. Failure to observe this
warning could result in personal injury or death from electrical
shock.

NOTE: Failure to observe the above warning will immediately void the
warranty.

Fault Isolation

If two network devices fail to communicate through the LANMaster T8,
consider the following:

Are the LEDs described in the previous section functioning
properly?

Do network devices have Link Integrity enabled?

Do network devices communicate when the LANMaster T8 is
not installed between them? 

Is flat or “silver satin” wire used in site internal wiring?

Are internal wiring patch cords, punch down blocks, and wall
jacks properly pinned or configured?

Is the thinnet cable unbroken and properly connected?

Are network interface cards properly configured?
