800-150 Exam Dumps : Supporting Cisco Devices for Field Technicians (FLDTEC)

After powering off a Cisco device in preparation for chassis replacement, theimmediate next stepis tolabel and remove all I/O cables. This step is crucial to ensure that all connections can be accurately restored after the new chassis is installed.​

Proper labeling prevents confusion and potential misconfigurations during reassembly. Only after all cables are safely disconnected should you proceed to remove the chassis ground and then the chassis itself.​

In theFLDTEC course, the process for removing or replacing asupervisor module— especially thestandbysupervisor— in a modular switch like theCisco MDS 9700is clearly outlined. Cisco documentation states:

"Before removing a standby supervisor module, it must first be placed into out-of-service mode using the CLI command system no supervisor <slot-number> or via the appropriate management interface."

This action ensures the systemacknowledges the supervisor is no longer participating in redundancy, allowing a safe and controlled removal without impacting system operations.

Why not the other options?

A. Shut down the entire switch→ Not required; MDS switches are built for high availability and allow hot-swap operations.

C. Disconnect all network interface cables→ This applies to line cards or interfaces, not to supervisor removal specifically.

D. Perform a manual failover→ Failover is requiredwhen removing the active supervisor, not the standby one.

On Cisco Catalyst 8000 Series Edge platforms, removing the chassis cover provides access to internal components such asDIMMs (Dual In-line Memory Modules)andSSDs (Solid-State Drives). These components are located internally and require the removal of the chassis cover for maintenance or replacement.​

DIMMsare used for system memory and are essential for the router's operation.

SSDsprovide storage for system software and configurations.​

Other components likeNetwork Interface Modules (NIMs)andtransceiversare typically accessible externally and do not require chassis cover removal.​
