3.4.1 - Hardware Failure Issues

Flashcards covering hardware failure issues, power considerations, and troubleshooting steps in a network environment.

What type of power anomalies can affect network devices?

Surges, spikes, under-voltage events, and power failures.

What is the primary function of an uninterruptible power supply (UPS) in an enterprise network?

To provide time to switch to a secondary power source or shut down the system gracefully.

Besides power issues, what other components should be considered when troubleshooting hardware failure?

Host network adapters, switch/router/modem appliances, and cabling.

What steps can be taken to troubleshoot a potentially failing network adapter or appliance?

Verify the driver is working correctly, replace the driver, confirm operation with status LEDs, and check that plug-in cards and modules are seated correctly.

What are some considerations for preventing overheating issues with network hardware?

Ensure good airflow, check for dust clogs, and avoid direct sunlight.

How should you approach troubleshooting a suspected switch issue at the Data Link layer?

Analyze the network topology to identify the affected part of the network and the problematic bridging or switching device.

What is a simple troubleshooting step that can often resolve switch problems?

Resetting the switch to clear transitory errors.

What precautions should be taken before restarting a switch, router, or server?

Restarting a network device can be disruptive. Identify potential impacts and seek authorization before proceeding.

What happens to unsaved changes in the running configuration of a network device after a restart?

Any unsaved changes in the running configuration will be discarded.
