TIP: By default, all access ports are configured as Ethernet interfaces. If you insert a Fibre Channel
transceiver, the LEDs do not light until you configure the port as a Fibre Channel interface in
Junos OS. Likewise, the LEDs do not light if you insert an Ethernet transceiver in a port configured
as a Fibre Channel interface.
Table 98 on page 531 describes the SFP+ access port LEDs.
