The receptacle is foolproof. If you cannot insert the plug into the receptacle, re-orient the plug
rather than use excessive force to push it in.
2. Use a cable tie to secure the power cord to the handle of the power supply, as shown in Figure 35.
3. Connect the other end of the power cord to the DC power source.

Verifying the installation
After you complete the installation, verify that:
• There is enough space for heat dissipation around the switch, and the rack is stable.
• The grounding cable is securely connected.
• The correct power source is used.
• The power cords are properly connected.
• All the interface cables are cabled indoors. If any cable is routed outdoors, verify that the socket
strip with lightning protection and lightning arresters for network ports have been properly
connected.
