The LEDs labeled Link/Activity LED in Figure 8 on page 21 and Figure 9 on page 22 indicate
link activity or faults. The LEDs labeled Status LED in Figure 8 on page 21 and
Figure 9 on page 22 indicate link status.
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 5 on page 22 describes the SFP+ access port LEDs.
