system services will be interrupted.
Prerequisites
● The spare part is on hand.
● The power module that you want to replace has been located.
You can locate a component in either of the following ways:
● Locating a component based on alarms in DeviceManager: On the Alarms and Events
page of DeviceManager, view the help information and determine the ID of the
component to be replaced. Then locate the component at your site based on its ID.
● Locating a component based on the status of its Running/Alarm indicator: For details
about the indicators on
dierent components, see Indicator Introduction of each
component in the Product Description specic to your product model and version.
● Before replacing a power module, ensure that the other power module is
working properly.
Precautions
● Do not touch the connectors of a power module and a power cable.
● Remove and insert a power module with even force. Excessive force may
damage the appearance or connectors of the power module.
● Remove only one power module at a time.
● A power module must be replaced within three minutes. Otherwise, the
system heat dissipation is compromised.
