Connectors and Indicators
CONNECTORS
Eight (8) straight-through RJ-45 connectors, labeled 1X-8X, and one
(1) crossover RJ-45 connector, labeled 8I, are located on the front of
the LANMaster T8-FL.
One (1) TX and one (1) RX fiber ST connector and one (1) AC power
supply adapter connector are located at the LANMaster T8-FL back.
LED INDICATORS
Steady green Link/RX LEDs indicate (for each port 1-8) the integrity
of the network link at the RJ-45 connector. Blinking green Link/RX
LEDs indicate (for each port) reception of valid data.
Steady green FL LED indicates the integrity of the network link at the
fiber receive (RX) connector. Blinking green FL LED indicates
reception of valid data.
Blinking green TX LED
indicates transmission of
valid data at the fiber transmit
(TX) connector.
Steady green Power LED
indicates connection of the
LANMaster T8-FL to external AC power.
Blinking yellow Collision LED indicate network collisions.
5. MAINTENANCE
WARNING: DO NOT, UNDER ANY CIRCUMSTANCES, open
and attempt to repair the LANMaster T8-FL. 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-
FL, 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-FL
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?
•
Are network interface cards properly configured?
•
Are network cables and connectors properly installed?
