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)

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.
