Juniper Networks EX4200 사용자 설명서

SFP transceivers are supported in all four ports.

The ports that support SFP+ transceivers are labeled 10 G on the uplink module’s
faceplate (see Figure 25 on page 35).

NOTE: When an SFP+ uplink module is operating in 10-gigabit mode:

■

Only the 10-gigabit ports (ports 0 and 2) are enabled.

■

You can use only SFP+ transceivers in those ports.

When an SFP+ uplink module is operating in 1-gigabit mode:

■

All four ports are enabled.

■

You can use only SFP transceivers in all four ports.

The SFP+ uplink module has an LED on the faceplate (labeled Operating mode LED
in Figure 25 on page 35) that indicates the operating mode. If the uplink module is
operating in the 10-gigabit mode, the LED is lit. If the uplink module is operating in
the 1-gigabit mode, the LED is unlit.

SFP+ uplink modules are shipped with dust covers preinstalled in the ports.

NOTE: On an EX3200 switch, if you install a transceiver in an SFP+ uplink module
when the uplink module is operating in the 1-gigabit mode, a corresponding network
port from the last four built-in ports is disabled. For example, if you install an SFP+
transceiver in port 2 on the uplink module (

ge-0/1/3

), then 

ge-0/0/23

 is disabled.

The disabled port is not listed in the output of 

show interface

 commands.

The SFP+ uplink module requires JUNOS Software for EX Series switches, Release
9.4 or later.

Figure 26 on page 37 shows the XFP uplink module, which provides two ports for
10-gigabit XFP transceivers.
