Chapter 3 Starting and Configuring the Router
Checking Conditions Prior to System Startup
Fan Failures
When the system power is on, all five fans should be operational. The system continues to operate if a fan fails. When a fan fails, the system displays the following message:
router:
If the air temperature exceeds a defined threshold, the system controller displays warning messages on the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts down the system.
If the system does shut down because the temperature exceeded the shutdown threshold, the system displays the following message on the console screen and in the environment display when the system restarts:
Queued messages:
For complete descriptions and instructions for the environmental monitor commands, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications, which are available online.
Checking Conditions Prior to System Startup
Check the following conditions before you start your router:
•The port adapter is inserted in its slot and the port adapter lever is in the locked position.
•The network interface cable is connected to the port adapter.
•A CompactFlash Disk is installed.
•SFP modules and their
•The optional USB Flash memory module or Aladdin USB eToken Pro key is installed.
•The optional Fast Ethernet Management port cable is installed.
•The console terminal is turned on.
You are now ready to start your router. Proceed to the “Starting the System and Observing Initial Conditions” section on page
Starting the System and Observing Initial Conditions
After installing your Cisco 7201 router and connecting cables, start the router as follows:
Step 1 At the front of the router, place the power switch on the power supply in the on (O) position. Step 2 Listen for the fans; you should immediately hear them operating.
Step 3 During the boot process, observe the system LEDs. The LEDs on the port adapter go on and off in irregular sequence. They may go on, go out, and go on again for a short time. On the router, the green STATUS LED comes on and stays on.
Step 4 Observe the initialization process. When the system boot is complete (a few seconds), the processor begins to initialize the port adapter and the I/O subsystem. During this initialization, the LEDs on the port adapter probably will flash on and off.
