Port LED is Off on AT-SBx31XZ4 XFP Line Card
For fiber optic uplink ports that have an XFP transceiver installed, verify
that the 1000 LINK LED is ON. If a 1000 LINK LED is off but the
transceiver is present, do the following:
Verify that the end node connected to the port is powered ON and is
operating properly.
Check that the fiber optic cable is securely connected to the XFP
transceiver in the AT-SBx31XZ4 XFP Line Card and to the port on the
remote end node. The dual ports in an XFP transceiver consist of two
separate connectors, where each connector connects to a separate
fiber strand.

When you connect a fiber optic cable, be sure that the receive fiber
connector of the XFP transceiver is connected to the transmit
connector on the remote end node, and that the transmit fiber
connector is connected to the receive connector on the remote node.
Make sure that you are using the appropriate type of fiber optic cable
and that the cable length does not exceed the allowed maximum
distance. For cable specifications, refer to the data sheet for your XFP
transceiver.
Use a fiber optic tester to test the attenuation on the cable to determine
if the strength of the fiber optic signal falls below acceptable limits. For
fiber optic port specifications, refer to the data sheet for your XFP
transceiver.
Check that the operating specifications (for instance, wavelength and
maximum operating distance) of the fiber optic port on the remote end
node are compatible with the fiber optic port on the AT-SBx31XZ4 XFP
Line Card.
Check to be sure that the fiber optic ports on theAT-SBx31XZ4 XFP
Line Card and on the remote end node are operating at the same
speed and duplex mode.
Verify that any optional XFP transceivers are completely inserted into
the SP slot on the front of the switch.
