The electrical section is capable of interfacing with any 10BaseT or
100BaseT RJ-45 twisted pair port. If the ethernet port supports
auto negotiation, the
DL221/A
can be set to auto negotiate for
optimum performance. If the ethernet port does not support auto
negotiation, or if a fixed data rate and/or fixed half or full duplex
configuration is desired, the
Series DL221/DL221A
transceivers
can be forced into 10BaseT or 100BaseT mode, and forced into
half or full duplex mode. In addition, a crossover switch is pro-
vided, which allows the
Series DL221/DL221A
transceivers to
directly connect to either a standard or a crossover ethernet port.
The optical section is a 100BaseFX connection at all times. The
DL221
family of transceivers supports bi-directional transmission
over two single mode fibers. The
DL221A family
of transceivers
supports bi-directional transmission over a single mode fiber. In
both cases, Radiants technology allows for extended transmission
distances beyond the ethernet standard.

If the problem persists after carrying out the procedure, do the
following: exchange two different channels with one another
(both copper and fiber connections), and re-perform the requested
setup. If the problem still persists, there is probably some sort of
general network failure. Contact the Radiant Communications
technical support department for assistance.

Improper network traffic
On the setup mode switches,
move S6 to the DOWN position,
and move it back to the UP
position after one second.
Check the channel configuration
on the mode setup switches.
Check that both ends of the fiber
optic link are set to the same
mode (Half Duplex or Full
Duplex)
Check that both sides of the UTP
connection are in the same mode
(10 Mbps Half duplex or 10 Mbps
full duplex or 100 Mbps Half
Duplex or 100 Mbps full duplex).
