Follow these steps to connect the Cisco 800 series router to a hub:
Step 1 Connect the yellow Ethernet cable from the yellow Ethernet port (Cisco 801 and 802 routers) or from the yellow
Ethernet port with the number 0 (Cisco 803 and 804 routers) on the back panel of the router to the Ethernet port on
the hub.

Step 2 Verify that the HUB/NO HUB switch on the left side of the back panel has been set to the HUB position (in). If the
button is out, press it to set it to the in position.
Note The HUB/NO HUB button corresponds to the Ethernet port on Cisco 801 and 802 routers and to Ethernet
port 0 on Cisco 803 and 804 routers.
Caution Always connect the yellow cable or Ethernet cable that you supply to the yellow ports on the router. Do not connect
the cable to an ISDN S/T or U port or to a Network Termination 1 (NT1) device. Accidently connecting the cable
to the wrong port can damage your router.
