Returning the defective part
In the materials shipped with a replacement SCR part, HP specifies whether or not the defective
component must be returned to HP. Where required, you must ship the defective component back to HP
within a defined period of time, normally five business days. The defective component must be returned
with the associated documentation provided in the shipping material. Failure to return the defective
component may result in HP billing you for the replacement. HP pays all shipping and return costs for
CSR components, and determines the courier/carrier used.
Replacing a power supply/blower assembly
The power supply and blower are separately replaceable components. It is not necessary to remove the
power supply to replace a failed blower.
Before you begin
Always use proper antistatic protection as described in the documentation that shipped with your system.
You do not need to power off the enclosure to replace a power supply.
Be aware that the power supply may be hot to the touch.
Verify that the status LED is out on the power supply/blower assembly that you are replacing.
CAUTION:
You have only 7 minutes to complete the power supply replacement! Both power supplies must be
installed for the enclosure to cool properly. When a power supply is removed, the enclosure can
overheat and shutdown in approximately 7 minutes. If a power supply fails, leave it installed until
a replacement is available.
Removing a power supply
To remove a power supply:
1. Disengage the power cord lock ( Figure 30 -1), and then disconnect the AC power cord from the
power supply.
TIP:
When removing the left power supply, ensure that the cord lock on the right power supply is
engaged to avoid inadvertently disconnecting the right power supply. Also, take care to avoid
disrupting the cables on the I/O module to the left of the power supply.
2. Lift up on the mounting latch ( Figure 30 -2), grasp the blower ( Figure 30 -3) and pull the power
supply out of the enclosure.
