Chapter 1 Overview
Port Adapter Slot Locations on the Supported Platforms
Cisco 7204 routers and Cisco 7204VXR routers have four slots for port adapters, and one slot for an
input/output (I/O) controller. The slots are numbered from the lower left to the upper right, beginning
with slot 1 and continuing through slot 4. You can place a port adapter in any of the slots (slot 1 through
slot 4). Slot 0 is always reserved for the I/O controller. Figure 1-14 shows the slot numbering on a Cisco
7204 router. The Cisco 7204VXR router is not shown.
