Copper permanent link
PATCH PANEL ===== fixed horizontal cable ===== OUTLET
Permanent-link certification targets the fixed installed cabling using the appropriate permanent-link adapters.

Installation Drawings & Diagrams
Simple diagrams that explain what is actually included in a link, path or documentation chain.
Copper channel
SWITCH -- patch cord -- PATCH PANEL ==== CABLE ==== OUTLET -- patch cord -- DEVICE
A channel includes the relevant patch cords as well as the permanent cabling.
Fibre path
ACTIVE PORT -- PATCH -- PANEL ==== FIBRE ==== PANEL -- PATCH -- ACTIVE PORT
Document connector type, fibre type, polarity and each passive event relevant to the loss budget.
A/B power path
UPS/PDU A ---- PSU A [DEVICE] PSU B ---- UPS/PDU B
Two power cords are not useful redundancy if both ultimately depend on the same single upstream source.
Typical access network
WAN -> FIREWALL -> CORE/DISTRIBUTION -> ACCESS SWITCH -> AP / CAMERA / USER
This is a logical example, not a prescribed architecture. Redundancy, routing and segmentation depend on the project.
Rack documentation chain
OUTLET ID -> CABLE ID -> PATCH PANEL PORT -> SWITCH PORT -> VLAN / DEVICE
Keeping this chain consistent is what makes later troubleshooting fast.
