Installing Your Router

Connecting Hubs

If you have a Cisco 803, 804, or 804 IDSL router, you can connect as many as four hubs.

Before connecting a hub, see Table 2-2, and do the following:

•Choose Ethernet cables.

•On the router, set the HUB/NO HUB or TO HUB/TO PC button.

•On the hub, set the HUB/NO HUB button or its equivalent.

Follow the steps in Figure 2-1to connect a hub to a Cisco 800 series ISDN or IDSL router. This figure shows a Cisco 803 router with four Ethernet ports.

Caution Always connect the yellow cable or an Ethernet cable to the yellow ports on the router. Do not connect the cable to an ISDN S/T or U port, to an IDSL port, or to an NT1. Connecting the cable to the wrong port or NT1 can damage your router.
