Precautions
•
Wear an ESD wrist strap and make sure it makes good skin
contact and is reliably grounded.
•
Make sure the voltage of the power source is as required by the
power module, and the output voltage of the power module is as
required by the device.
•
Do not touch any bare wire or terminal.
•
Never place the power module in wet locations and prevent
liquid from flowing into the power module.
•
To avoid power module damage, do not open the power module.
If a failure occurs on the internal wires or units, contact H3C
Support.
Procedure
You need to prepare an ESD wrist strap, a flathead screwdriver, and
a Phillips screwdriver for power module installation and removal.
The installation and removal procedures are the same for the
PSR300-12A and PSR300-12D power modules. This section uses
the PSR300-12A power module as an example.
Installing a power module
1.
Remove the filler panel (if any) from the target slot.
2.
Unpack the power module and verify that the input mode of the
power module is as required.
