The highlighted components in all three Cisco UCS server models (5108 B-Series Blade Server Chassis, X9508 X Series Modular Server Chassis, and C225 M6 Rack Server) are fan modules, which are field-replaceable units responsible for cooling the system.

The highlighted components in the images correspond tocooling fans— these are essential for maintaining optimal thermal conditions within each Cisco UCS server type.Here's a breakdown of what's visible in each:

Cisco UCS 5108 B-Series Blade Server Chassis: The highlighted vertical rectangular components arefan modules, which provide high-efficiency airflow for the densely packed blades.

Cisco UCS X9508 X-Series Modular Server Chassis: The front-facingfan traysare clearly marked, used to cool the modular nodes and shared infrastructure.

Cisco UCS C225 M6 Rack Server: The highlighted components on the side of the motherboard are alsofan modules, directly responsible for cooling the CPU, memory, and other internal components.

These fans arefield-replaceable units (FRUs)and are routinely accessed by technicians during preventive maintenance or fault replacement.

TheFLDTECtraining describes theTCP/IP encapsulationas a step-by-step process where data is passed down through the layers of the TCP/IP model:

Application Layer: User data is created (email, file, request) and the application layeradds the application header, creating a data payload.

Transport Layer: The data is segmented. Each segment receives a transport-layer header (TCP/UDP), enabling proper sequencing and error handling at the destination.

Internet Layer: Segments are encapsulated intopackets(IP datagrams), with an IPheader added to facilitate routing between networks.

Link Layer: Finally, packets are framed with Layer 2 headers and trailers (including theFrame Check Sequencefor error detection), creating aframeready to be transmitted on the physical medium.

This layered encapsulation ensuresinteroperabilityandtroubleshooting clarity, which is why it is emphasized inFLDTEC’s IOS Software Basics module.
