Connecting to the StackPower Ports
Caution Removing and installing the StackWise cable can shorten its useful life. Do not remove and
insert the cable more often than is absolutely necessary (installing and removing it up to 200
times is supported).
When you need to remove the StackWise cable from the connector, make sure to fully unscrew the
correct screws. When the connectors are not being used, replace the dust covers.
Connecting to the StackPower Ports
Before connecting the StackPower cables, review the “Planning a StackPower Stack” section on
page 2-8. Always use a Cisco-approved StackPower cable to connect the switches. To prevent
misconfiguration, the StackPower ports on the switch are keyed and have colored bands that match the
keying and bands on the StackPower cable connectors.
Follow these steps to connect the StackPower cable to the StackPower ports:
Step 1 Remove the dust covers from the StackPower cable connectors.
Step 2 Connect the end of the cable with a green band to either StackPower port on the first switch. Align the
connector correctly, and insert the it into a StackPower port on the switch rear panel. (Figure 2-16).
Step 3 Connect the end of the cable with the yellow band to another Catalyst 3850 switch (to configure
StackPower power sharing).
Step 4 Hand-tighten the captive screws to secure the StackPower cable connectors in place.
