SFP+ Interfaces
The Cisco Catalyst 3750-X Series and 3560-X Series Switches support four optional network modules for uplink
ports. The default switch configuration doesn’t include the uplink module; at the time of switch purchase the
customer has the flexibility to choose from the network modules described in Table 3.
Table 3. Network Module Numbers and Descriptions
Product Number Product Description
C3KX-NM-1G Four GbE port network module

The SFP+ interface supports both 10GbE and GbE port, allowing customers to use their investment in GbE SFP
and upgrade to 10GbE when business demands change, without having to do a comprehensive upgrade of the
access switch. The four uplink modules are hot swappable. The four network modules can be used in any of the
combinations shown in Table 4.
