Distribution Systems in Networking Flashcards
What is a cable distribution system?
A structured layout and organization of network media within a building to ensure efficient and reliable data communication.
What is another name for a cable distribution system?
Cable plant.
What are the main components of a cable distribution system?
Cables, wall jacks, patch panels, MDF, IDF, and supporting infrastructure.
What is the role of a Main Distribution Frame (MDF)?
Acts as the starting point for all interior cabling, hosting backbone switches and main routers.
What is the function of an Intermediate Distribution Frame (IDF)?
Serves smaller sections of the network by connecting to the MDF via trunk cables.
What is a Demarcation Point?
The point where the ISP connection ends and the organization’s network begins.
What are patch panels used for?
To organize and connect network cables to switches, preventing direct connections that may wear down switch ports.
What is a Vertical Cross-Connect?
A method of routing cables between building floors.
What is the function of a Power Distribution Unit (PDU)?
Distributes power to network equipment within racks.
What is the purpose of an Uninterruptible Power Supply (UPS)?
Provides emergency power to networking equipment during power outages.
How does a generator help in network power distribution?
Provides long-term backup power during extended outages, usually paired with UPS for seamless transitions.
What is the ideal temperature range for networking equipment?
68–77°F (20–25°C).
What is the recommended humidity range for data centers?
40–60% relative humidity.
What is the function of hot aisle/cold aisle configurations?
Optimizes airflow to manage cooling efficiently in data centers.
Why should wet pipe fire suppression systems be avoided in data centers?
They use water, which can damage sensitive electronic equipment.
What type of fire suppression system is recommended for data centers?
Clean agent systems using inert gases or halocarbon agents to prevent water damage.
What is a toner probe (fox and hound) used for?
Identifies, traces, and tests network cables in distribution systems.
