12.1
Accessing a Power Supply Unit
■
Because the power supply unit (PSU) does not belong to any domain, active
replacement and hot replacement use the same procedure. See
Removal and Replacement (Power supply unit/Fan unit)” on page 4-8
■
For cold replacement, stop the domain and then power off the server. See
Section 4.5.1, “Powering off the Server” on page 4-12
Caution –
To ensure that you and bystanders are not exposed to harm and to
prevent damage to the system, observe the ESD safety precautions. See
.
1. From the XSCF Shell prompt, use the
replacefru
command to disable the
power supply unit to be removed.
The
replacefru
command is a menu-driven interactive command. The
replacefru
continues operating while the power supply unit is removed.
Afterwards, it performs the power supply unit test. For details, see
“FRU Removal and Replacement (Power supply unit/Fan unit)” on page 4-8
2. Loosen the thumbscrew of the cable management arm that is located on the
right side when you are facing the rear of the server.
3. Pull out the cable management arm while keeping it from coming into contact
with the power supply unit.
