Step 5
Listen for fans in both the router shelf and the dial shelf. You should hear them operating
immediately.
During the boot process, the LEDs on most of the port adapters in the router shelf and on the dial
shelf cards and dial shelf controller cards light on and off in irregular sequence while the system is
running initial self-diagnostic tests. On the router shelf I/O controller, the I/O power OK LED comes
on immediately.
For a description of normal dial shelf LED states, proceed to the “Observing Access Server LEDs”
section on page 4-3. Normal router shelf startup is discussed in the “Starting the Cisco 7206” section
on page 4-8. If everything seems to be normal, complete the startup check with a console connection
as described in the “Viewing Your System Configuration” section on page 4-10.
