Cisco Catalyst 3750-X Series Switches support 4 optional network modules for uplink ports (Figure 1);
The default switch configuration doesn’t include the uplink module;
When purchasing switch, customers have flexibility to choose any group of network modules described below:
| Product Number | Product Description |
| C3KX-NM-1G | Four GbE port network module |
| C3KX-NM-10G | Two 10GbE SFP+ ports network module with four physical ports with two SFP+ and two regular SFP ports |
| C3KX-NM-10GT | Two 10GB-T ports network module |
| C3KX-SM-10G | Service Module with two 10GbE SFP+ ports network module for Netflow and MACsec encryption |
Dual Redundant Modular Power Supplies
Cisco Catalyst 3750-X Series and 3560-X Series Switches support dual redundant power supplies (Figure 2);
One power supply is shipped with the switch by default;
Other power supply/suppliers can be purchased when ordering the switch or next time according to your needs.
If only one power supply is installed, it should always be in the power supply bay 1.
Table below shows the different power supplies available in these switches and available PoE power.
