Making External Connections
to Cisco 4000 Series Routers
4
This chapter describes how to connect your Cisco 4000 series router to networks and
external devices, and contains the following sections:
• Preparing to Make Connections
• Console Port and Auxiliary Port Connection Considerations
• Network Connection Considerations
• Connecting Routers with a DC-Input Power Supply
• Powering Up the Router
Preparing to Make Connections
When viewed from the rear, the power cable and power switch appear on the right side of
the router chassis. The system console port, auxiliary port, and network processor module
ports appear to the left of the power cable and switch. (See Figure 4-1.)
Slot Numbering
The chassis contains slots for three network processor modules. These slots correspond to
the three slot numbers printed on the front panel of the chassis. (See Figure 4-1.) Slot
numbers represent the order in which the system scans the network processor modules.
Network processor module location is not slot dependent. Any module can be moved to any
other available slot location. For optimum heat dissipation, use the center slot position, slot
2, for the FDDI module if one is present.
