StackPower Connector

The C9300 switches have a StackPower connector for use with Cisco StackPower cables to configure a switch
power stack that includes up to four switches. A switch power stack can be configured in redundant or
power-sharing mode.
You can order these StackPower cables from your Cisco sales representative:
• CAB-SPWR-30CM (0.3-meter cable)
• CAB-SPWR-150CM (1.5-meter cable)
For details about connecting StackPower cables and StackPower guidelines, see

USB 3.0 SSD Port

To support the storage needs on the switch, the Cisco Catalyst 9300 Series Switches provide support for
pluggable 120 GB and 240 GB USB 3.0 Solid State Drive (SSD) modules. The USB 3.0 SSD module slot is
located at the rear panel of the switch. The storage drive can also be used to save packet captures and trace
logs generated by the operating system. The USB 3.0 SSD device is field replaceable.
Note

Ethernet Management Port

You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100/1000 Ethernet management port or one of the console ports. The 10/100/1000 Ethernet management
port is a VPN routing/forwarding (VRF) interface and uses a RJ-45 crossover or straight-through cable.
