Parts Replacement
Impact on the System
During the replacement of an expansion module, the system switches services from ports on
this module to ports on the other expansion module in the same disk enclosure. Only one
expansion module is working, causing the system reliability to degrade. You are advised to
replace an expansion module during off-peak hours.

You can locate a component in either of the following ways:

DeviceManager, view the help information and locate the component to be replaced.
l Locating a component based on the status of its alarm indicator: For details about the indicators on
different components, see indicator introduction in the Product Description specific to your product.
You have confirmed that the cables of the expansion module to be replaced are properly
connected using Huawei Storage Networking Assistant. For details, see
