Uplink Module
(PIC 1) Uplink Module
(PIC 2)
Each SFP+ uplink module provides four ports. Each module can house four 10-gigabit
small form-factor pluggable (SFP+) transceivers or four 1-gigabit small form-factor
pluggable (SFP) transceivers.
NOTE: When a new uplink module is installed in the switch or an existing
uplink module is replaced with another uplink module, the switch detects
the newly installed uplink module. The switch creates the required interfaces
when new transceivers are installed in those ports.
The operating mode for an SFP+ uplink module is shown in the output of the
show chassis
pic fpc-slot slot number pic-slot 1
command.
You can use the uplink module ports to connect an access switch to a distribution switch.
Figure 18 on page 28 shows the SFP+ uplink module.

The SFP+ uplink module has an LED on the faceplate (labeled ST) that indicates the
status of the uplink module. See Figure 18 on page 28.
Table 12 on page 29 describes the LED on the uplink module in a J-EX4500 switch.
