Connecting your IOLAN to the Network

Dedicated Console Port

The rack mount IOLAN models have a dedicated Console port, located on the LED side of the
IOLAN. You can use the supplied Administration cable (with the supplied RJ45JDB9F adapter if
needed) to connect a terminal to the Console/Admin port to view diagnostic information and/or
configure the IOLAN using the Menu or Command Line Interface (CLI). You can configure the baud
rate and flow control of the dedicated Console port.
Connecting your IOLAN to the Network
To connect the IOLAN to the network, use a straight-through two-pair Category 5 unshielded
twisted-pair (UTP) cable, or four-pair for Gigabit connections. Connect the RJ-45 Ethernet port on
the IOLAN to a switch, hub, repeater, server or other network device.
Powering up your IOLAN

Desktop/Rack Mount Models (excluding Electric Utility models)

To power up the desktop or rack mount IOLAN, perform the following steps:
1. Rack mount models only: Using the rack mount brackets included 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. Rack mount models only: Power on the IOLAN unit using the Power ON/OFF switch.
4. You will see the LEDs blink 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 desktop 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 setting of jumpers may be required:
zIOLAN DS and SDS models where EIA-422/485 line termination is required.
zIOLAN I/O models with Digital I/O for setting the channels as input or output.
Note: To comply with the Telcordia GR-1089 NEBS standard, connect Ethernet interfaces only to
intra-building or unexposed wiring or cabling. The intra-building cable must be shielded and
the shield must be grounded at both ends.
Alternatively, if shielded cabling is not used, the Ethernet wiring (cabling) must directly
connect to equipment within the same frame, cabinet or line-up and the equipment must be
separated by a distance of 6 meters or less.
Note: WARNING
The intra-building port(s) of the equipment or subassembly is suitable for connection to
intra-building or unexposed wiring or cabling only. The intra-building port(s) of the
equipment or subassembly MUST NOT be metallically connected to interfaces that
connect to the OSP or its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and
require isolation from the exposed OSP cabling. The addition of Primary Protectors is not
sufficient protection in order to connect these interfaces metallically to OSP wiring.
