Your Cisco 761,Cisco 762, Cisco 765, Cisco 771, Cisco 772, or Cisco 775 router can be
either a hub or a node. The HUB/NODE switch eliminates the need for a crossover cable.
When the switch is in NODE position, the router is seen as a node and connects to a hub
with a straight Ethernet cable. When the switch is in HUB position, the router can connect
to a network interface card (NIC) installed in a PC.
Cisco 766 and Cisco 776 routers have an unmanaged 4-port Ethernet hub. If you are
connecting a Cisco 766 or Cisco 776 router to another Ethernet hub, you must use a
crossover cable.
