Preventing Router Damage
Use the following guidelines when connecting devices to your router:
• Connect the color-coded cables supplied by Cisco to the color-coded ports on
the back panel.
• If you must supply your own cable, see the “Cabling” section. If this section
does not provide specifications for a particular cable, we strongly recommend
ordering the cable from Cisco.
