* 1. These values are per TIA/EIA and other industrial specifications.
* 2. These values are one example of the performance that can be obtained with a
new fiber installation.
4-6. System Power-On and Testing
1. Take your JetNet 3008 / JetNet 3008f Industrial 8-port Fast Ethernet
Switch out from the box.
2. To place the JetNet 3008 on the DIN-Rail track, refer to the Mounting
Installation section.
3. Pull the terminal block off the JetNet 3008 and wire the power lines.
Refer to the Wiring the DC Power Inputs section for how to wire the
power inputs.
4. PWR1 and PWR2 dual power inputs can be connected to power
sources simultaneously. When the primary power source fails (the
default setting is PWR1), the system will automatically switch to the
secondary power source (PWR2), preventing any power interruption.
5. Check the LEDs for PWR1 and PWR2 to make sure that your JetNet
3008 is operating normally.
6. Use Category-5 or above straight through Ethernet cables with RJ-45
connectors to connect network devices.
