Issue 15 (2019-12-30)
Before replacing a power module, ensure that the other power module is
working properly.
One BBU is installed in each power module. When a power module is being
replaced, ensure that the BBU in the other power module is working correctly.
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.
