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.

SFP uplink modules are shipped with dust covers preinstalled in the ports.
SFP+ uplink modules can be used for either SFP+ or SFP transceivers. You configure the
operating mode on the module to match the type of transceiver you want to use—for
