Chapter 9. Management switch maintenance procedures

(optional)

Procedures for replacing the Lenovo ThinkAgile CP management switch.

Note: A dedicated out-of-band management switch is required for this solution. If the Lenovo ThinkSystem

NE0152T RackSwitch is not used, you must provide an out-of-band management switch with the correct

configuration. Disregard this procedure if you are not including the Lenovo NE0152T as the management

switch in your solution.

Refer to Chapter 2 "Roles and responsibilities" on page 5 to determine who can perform these procedures.

This section describes how to replace a hardware management network cable.

Procedure performed by: Customer or field service

When replacing cables that connect any Baseboard Management Controller (BMC) from the compute

enclosure, storage controllers, or the primary interconnect-dedicated port to the management switch, you

are required to unplug all hardware management network cables and then plug back into the management

switch to initiate a DHCP renewal. This operation can be done live without any specific pre- or post-steps.

During this operation, the hardware management network, the storage HA feature, and hardware detection

functionality are unavailable. Hardware-related statistics also cannot be retrieved.

Procedure performed by: Customer or field service

If during the installation, the customer performs specific configuration within the current Management

Switch, such as creating a network segmentation for the ThinkAgile CP hardware management network, this

configuration needs to be ported to the newly installed Management Switch before plugging the cables back.
