Connecting the Switch Ports
Connecting the Switch Ports
10/100/1000, 10/100/1000 PoE+, or 10/100/1000 Cisco UPOE Ports
When you connect to servers, workstations, IP phones, wireless access points, and routers:
• Use a straight-through, twisted four-pair, Category 5 cable in a 10/100/1000 port.
• Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or
repeaters.
• Connect the other cable end to an RJ-45 port on the other device.
In some switch models, the 10/100/1000 ports support Power over Ethernet (PoE), PoE+, or Cisco
Universal Power Over Ethernet (Cisco UPOE).
• Support for IEEE 802.3af compliant powered devices (up to 15.4 W) PoE
• Support for IEEE 802.3at compliant powered devices (up to 30 W) PoE+
For more details, see the Catalyst 3850 Switch Hardware Installation Guide on Cisco.com.
Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. The
switch detects the required cable type for copper Ethernet connections and configures the interfaces. You
can use either a crossover or a straight-through cable for connections to a copper 10/100/1000 module
port on the switch, regardless of the type of connected device.
Step 1
Loosen the captive screws, and remove the blank
network module cover.
Step 2
Slide the network module into the opening until the
back of the module faceplate is flush with the switch
faceplate. Tighten the captive screws. For a list of
supported network modules, see the Catalyst 3850
