Figure 2-4. Routing Engine Utilization LEDs
The routing engine utilization LEDs indicate the degree of utilization of
the routing engine. An excessively high percentage of utilization
decreases throughput. If you see consistently high utilization—over
50–60%—reconfiguring the network will improve overall network
throughput, efficiency, and response time.
It is normal for the routing engine utilization LEDs to indicate high
utilization percentages during the self-test.

Figure 2-5. Swap Button and LED
The Swap button and LED on each interface card are used to "hot swap"
the card—that is, to replace it without switching the router off and
taking all networks down. For details, refer to "Replacing an Interface
Card (System Online)," page 3-21.
