Carefully plug the desired SFP transceiver (see Table 1) into its front-panel
socket. Ensure that it snapped into place.
2
Plug an O3-4D1L3 into a 3192 card slot; the module is two slots wide.

If the UNIT indicator does not turn on, verify that power is connected to
the mounting and that a good fuse is properly installed.

If the UNIT indicator is red, verify that the laser transceiver is properly
latched into its socket. If the indicator remains red, the O3-4D1L3 module
is defective and should be replaced.
