Preventing Damage to the Router
To prevent damage to your router, follow these guidelines when connecting devices to your router:
• Turn off power to the devices and to the router until all connections are completed.
Caution Do not turn on the devices until after you have completed all connections to the 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 “Cable Specifications” section on page A-28 for cabling
specifications. If this appendix does not provide specifications for a particular cable, we strongly
recommend ordering the cable from Cisco.
