Uplink Modules in EX4200 Switches
EX4200 switches support four types of uplink modules:
•
SFP uplink module—Provides four ports for 1-gigabit small form-factor pluggable(SFP)
transceivers.
•
SFP+ uplink module—Provides two ports for 10-gigabit small form-factor pluggable
(SFP+) transceivers when configured to operate in 10-gigabit mode or four ports for
1-gigabit small form-factor pluggable (SFP) transceivers when configured to operate
in 1-gigabit mode.
•
SFP+ Media Access Control Security (MACsec) uplink module—Provides two ports for
10-gigabit small form-factor pluggable (SFP+) transceivers when configured to operate
in 10-gigabit mode or four ports for 1-gigabit small form-factor pluggable (SFP)
transceivers when configured to operate in 1-gigabit mode. All four ports on the uplink
module are MACsec-capable.
•
XFP uplink module—Provides two ports for 10-gigabit small form-factor pluggable
(XFP) 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
if the uplink module has transceivers in its ports and when new transceivers
are installed in those ports.
NOTE: The packet forwarding process (pfem) restarts and causes traffic
loss, if you:
•
Install an uplink module (SFP, SFP+, SFP+ MACsec, or XFP)
•
Replace an existing uplink module with another uplink module
•
Change the operating mode of an SFP+ or SFP+ MACsec uplink module
(10-gigabit to 1-gigabit or 1-gigabit to 10-gigabit) installed in the switch
When connecting uplink module ports, you can install an SFP uplink module at one end
of the connection and install an SFP+ uplink module configured to operate in the 1-gigabit
mode at the other end. Likewise, you can install an XFP uplink module at one end of the
connection and install an SFP+ uplink module configured to operate in the 10-gigabit
mode at the other end.
