or four ports for 1-gigabit small form-factor pluggable (SFP) transceivers when
configured to operate in 1-gigabit mode.

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.

You can use the optional uplink module ports to connect an access switch to a
distribution switch. You can also use these ports to connect members of a Virtual
Chassis across multiple wiring closets.

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.
