Installing an Uplink Module in an EX3200 Switch
If your EX3200 switch includes an optional uplink module, you install it in the switch's
front panel. The different types of uplink modules are described in
“Uplink Modules in
EX3200 Switches” on page 15 .
The uplink module in EX3200 switches is a hot-removable and hot-insertable unit (FRU):
You can remove and replace it without powering off the switch or disrupting switch
functions.
NOTE: On an EX3200 switch, if you install an SFP uplink module or an SFP+
uplink module when the SFP+ uplink module is operating in the 1-gigabit
mode, all the network ports from the last four built-in ports are disabled and
remain disabled until you reboot the switch.
On an EX3200 switch, if you install a transceiver in an SFP uplink module or
in an SFP+ uplink module when the SFP+ 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 or SFP+ transceiver in port 2
on the uplink module (
ge-0/1/2
), then
ge-0/0/22
is disabled. The disabled
port is not listed in the output of
show interface
commands.
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.
