Access Port and Uplink Port LEDs on a QFX3500 Device

Each access port and uplink port on a QFX3500 device has two LEDs. The two figures in this topic show the location of those LEDs:

  • Figure 1 shows the location of the LEDs on the SFP+ access ports.

  • Figure 2 shows the location of the LEDs on the QSFP+ uplink ports.

The LEDs labeled Link/Activity LED in Figure 1 and Figure 2 indicate link activity or faults. The LEDs labeled Status LED in Figure 1 and Figure 2 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 1 describes the SFP+ access port LEDs.

Table 2 describes the QSFP+ uplink port LEDs.
