HUB/NO HUB button
(for Ethernet port)
Identifies device
connected to Ethernet
port and determines
Ethernet cable.
With the HUB/NO HUB button, you can connect hubs, servers, PCs, and workstations
using the yellow Ethernet (straight-through) cable instead of using a crossover Ethernet
cable, which you would need to supply. This button identifies the device that you
connect to the router Ethernet port using the yellow Ethernet cable. Setting the button
to HUB (in) indicates that you are connecting a hub; setting the button to NO HUB (out)
indicates that you are connecting a server, PC, or workstation. The default setting of this
button is HUB. If you reset the button to NO HUB, the router Ethernet connector crosses
over the signals transmitted to and received from the yellow Ethernet cable. For
information on how the setting of an equivalent hub button can affect the setting of this
router button, refer to the "Connecting an Ethernet Device" section in Chapter 2,
"Installing the Cisco 805 Router."
