7 POWER-UP/CHECK OUT PROCEDURE

Media Converter is powered up as soon as power is applied to the set top unit. The POWER
indicator (GREEN LED) on the media converter should light to indicate that power is applied.
If the POWER indicator does not come on, verify that the power connections between the media
converter and the power supply are secure. Verify that there is power present at the source. If this
procedure does not resolve the problem, replace the cable or power supply.
If the ALARM indicator (RED LED) is on, verify that the RJ45 connector and optical
connections are secure. Check power connection and verify that PWR LED is green. If the
ALM LED is still red press the reset button.

10/100 Mb/s Set Top Check Out Procedure

If the PC workstation port has been set to auto-select (i.e., full auto-negotiation) for speed and
duplex, the TPLink LED will be OFF when power is applied unless a valid optical link has
already been established with a remote optical port. If a valid optical link has been established,
FOLink LED will be YELLOW for 10 Mb/s operation or GREEN for 100 Mb/s operation. The
preferred mode of operation for the port is auto select for both speed and duplex. This will
insure that a link can be established regardless of the far end operational mode.
OptEnet 10/100BaseSX Media Converters support auto-negotiation as defined in TIA/EIA-785.
Auto-negotiation allows the unit to automatically select the highest performance level for
COPPER or FIBER.
OptEnet 10/100 Mb/s Media Converters support Medium Dependent Interface Crossover
(MDI-X). OptEnet Media Converter Ethernet ports allow connections to other hubs or switches
without a null-modem or crossover cable. If a null-modem or crossover cable has been used the
OptEnet 10/100 Mb/s Media Converter automatically detects this and switches the contacts to
match the other end.
Any blinking of a link LED indicates auto-negotiation in process. If a link LED continues to
blink for more than 30 seconds then the operation of the far end device (i.e., duplex and speed)
needs to be verified or changed.
