Powering Up the IOLAN

Powering Up the IOLAN

Desktop/Rack Mount Models

To power up the IOLAN, perform the following steps:
1. Rack Mount Models only: Using the rack mou nt brackets inclu ded with your IOLAN, you can
rack mount the IOLAN from the front or the back of the chassis, depending on your
environment. Make sure you don’t block the IOLAN’s side air vents. Each IOLAN is 1U in
height, and does not require any extra space between units; therefore, you can rack mount up to
five IOLANs in a 5U rack.
2. Plug the external power supply into the IOLAN and then into the electrical outlet. Connect it to
the PSE if you have a P series (Power over Ethernet) model.
3. You will see the LEDs cycle for several seconds and then remain a solid green, indicating that it
is ready to configure/use.
Before you start to configure the IOLAN, you should set the deskt op IOLAN jumpers if you want to
terminate the line or use the power in pin feature (instead of an external power supply, if your
desktop IOLAN model supports it).
In some circumstances, the settin g of jumpers may be required:
zIOLAN DS and SDS models where EIA-422/48 5 line termination is required.
zIOLAN I/O models with Di gital I/O for setting the channels as input or output.
zIOLAN I/O model s with Analog I/O for setting Voltage/Current.
See Appendix E, Setting Jumpers on page 361 to see how to set the jumpers for your IOLAN
desktop model.

I/O Models

To power up the IOLAN, perform the following steps:
1. Unplug the pow e r pl ugable terminal block from the IOLAN.
2. Loosen the screws and then insert your positive (+) wire into the left terminal and screw it down.
Insert the negative (-) wire into the right terminal and screw it down as shown below:
3. Plug the power terminal block back into the IOLAN.
4. Plug the power supply into the elect rical outlet.
5. You will see the LEDs cycle for several seconds and then remain a solid green, indicating that it
is ready to configure/use.
Before you start to configure the IOLAN, you should set the IOLAN jumpers for Digital I/O (see
Digital I/O Module on page 366) or Analog Input (Analog Input Mod ul e on page 367) channels.
