Drag and drop the failures from the left onto the responsible devices in the MDS...

Inability to manage or control switch functions → Supervisor module

Failure to maintain optimal temperatures → Fan module

Loss of connectivity on specific ports → Line card

Inability to establish fiber optic connections → Transceivers

Degraded internal data transfer between line cards → Fabric module

From theFLDTEC training materials, Cisco MDS switches are built for high availability and redundancy, but field technicians must know which component impacts whatfunction:

Supervisor Module: Manages control plane functions — a failure results in loss of system-level management or redundancy.

Fan Module: Essential for cooling — failure here leads to overheating and thermal alarms.

Line Card: Provides connectivity — port failures or loss of interface status originate from faulty line cards.

Transceivers (SFP/QSFP modules): Responsible for optical transmission — failure leads to fiber optic link issues.

Fabric Module: Critical for switching between line cards — its failure leads to degraded or disrupted internal traffic paths.

These mappings help techniciansisolate the source of faultsand proceed with the correctRMA or replacementprocedure.
