The key to problem solving in this system is to try to isolate the problem to a specific subsystem. By comparing what the system is doing to what it should be doing, the task of isolating and solving the problem is greatly simplified.
When problem solving, consider the following subsystems:
Power and cooling systems---Power supply, power cable, and fan
Ports, cables, and connections---Ports on the rear panel of the gateway and the cables that connect to them
Check the following items to help isolate the problem:
When the power switch is in the on position (|) and the power LED is on, make sure the fan is operating. If the fan is not operating, check the fan.
If the gateway shuts down after being on a short time, check the environmental conditions. The gateway might be overheating, resulting in a thermal-induced shutdown. Ensure that the chassis intake and exhaust vents are clear. Review the "General Site Requirements" section in Chapter 2, "Preparing to Install the Gateway." The operating temperature for the gateway is 32° to 104° F (0° to 40° C).
If the gateway fails to boot, but the power LED is on, check the power supply.
If the gateway constantly or intermittently reboots, there might be a problem with either the processor or the software, or a dynamic random-access memory (DRAM) single in-line memory module (SIMM) might be installed incorrectly.
The LEDs indicate the current operating condition of the gateway. By observing the LEDs, you can note any fault condition that the gateway is encountering, and then contact your system administrator or customer service, when necessary.
The following illustration shows the location of the LEDs on the front panel of the Cisco VG200.
