Figure2-8 Connecting a DC power cord for an IE4300-12P-PWR switch
NOTE:
•
The wire colors in the preceding figure are for illustration only.
•
The IE4300-12P-PWR switch supports dual DC power feeds. You can use two H3C DG-240-55
industrial power supplies connected in parallel for the switch to achieve 1+1 redundancy.
Verifying the installation
After you complete the installation, verify the following information:
•
There is enough space around the switch for heat dissipation.
•
The DIN rail is securely installed.
•
The grounding cable is connected correctly.
•
The power source is as required by the switch.
•
The power cords are correctly connected.
•
If an interface 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.
