Accept
Compare the transceiver model
against a list of supported
models. Accept if it is in the
list. Otherwise, automatically
set the speed to 1 Gbps and
set auto-negotiation to On.
If the transceiver is accepted, the Media parameter under Ethernet Ports » Configure Port Parameters shows
detailed information about the SFP transceiver, including Gigabit Ethernet Compliance Code, transmission media,
connector type, and link length. For example:
SFP 1000LX SM LC 10 km
SFP 1000T 100 m
If the transceiver is not recognized, it is rejected. An alarm is also generated and the port is blocked so that
no link can be established until the transceiver is replaced. The Media parameter shows the rejected SFP
transceiver is unidentified. For example:
SFP Unidentified
If no transceiver is installed on an SFP port, the Media parameter shows the SFP transceiver is unplugged:
SFP Unplugged
