6.3 Connecting the Sunny WebBox Directly to the Computer
1. Use the blue patch cable (Ethernet crossover cable) to connect the Sunny WebBox directly to
the computer (see ➀ ). The terminal on the computer is generally marked with the same symbol
as the network connection of the Sunny WebBox. If necessary, refer to the computer manual.
2. Connect the plug-in power supply to the Sunny WebBox and plug it into the socket-outlet
(see ➁ ).
☑ The Sunny WebBox starts up and is ready for operation once the "SYSTEM" and "POWER"
LEDs are green. The start-up procedure can take up to 90 seconds.
– If the "SYSTEM" or "POWER" LEDs do not glow green, please refer to Section
12.1 "General Troubleshooting for the Sunny WebBox" (page 47).
3. Set the computer to the network area of the Sunny WebBox (see Section 6.4 "Configuring the
Network Settings on the Computer" (page 26)).
Recommendation on network cabling
Should the patch cable supplied be too short, observe the following when buying a longer
cable:
• You need an Ethernet crossover cable.
• Unnecessarily long cables have an adverse effect on the signal quality.
The maximum permitted cable length is 100 m per segment.
• Use a high quality shielded twisted pair cable of category 5 (FTP Cat 5) or higher.
