For information about installing a fan module and fan specifications, see the "Technical Specifications"
chapter.

StackPower Connector

The switches have a StackPower connector for use with Cisco StackPower cables to configure a switch power
stack that includes up to nine 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

Planning a StackPower Stack,

.

Cisco Catalyst WS-C3850-48XS switch models do not have the StackPower connector.

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.

The 10/100/1000 Ethernet management port is an RJ-45 connector that should be connected to a Windows
workstation or a terminal server. Do not connect this port to another port in the same switch or to any port
within the same switch stack.
