Connecting the power cord for a PSR180-56A, PSR360-56A,
PSR720-56A, or PSR1110-56A power supply
The power cord connection procedure is the same for the PSR180-56A, PSR360-56A, PSR720-56A,
and PSR1110-56A power supplies. The following procedure uses a PSR360-56A power supply as an
example.
To connect the power cord for a PSR360-56A power supply:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Plug the female connector end of the power cord into the input socket of the power supply (see
callout 1 in
Figure2-25 ).
3. Use a cable tie to secure the power cord to the handle of the power supply (see callout 2 and
callout 3 in
Figure2-25 ).
4. Connect the other end of the power cord to a power source.
For a PSR360-56A, PSR720-56A, or PSR1110-56A power supply, you can connect the power
cord only to an AC power source. For a PSR180-56A power supply, you can connect the power
cord to an AC or HVDC power source.

Verifying the installation
Before powering on the switch, verify the following items:
•
There is enough space around the switch for heat dissipation.
•
The rack or workbench on which the switch is mounted is stable.
•
The grounding cable is securely connected.
•
The power source specifications are as required by the device.
•
The power cords are correctly connected.
•
If part of the network cable for a port is routed outdoors, verify that a network port lightning
protector is used for the port.
•
If a power line is routed from outdoors, verify that a surge protected power strip is used for the
switch.
NOTE:
For information about lightning protection for the switch, see H3C Lightning Protection Guide .
