Frequently Asked Questions - IFB-244 Series Planet

What is the IFB-244 Series used for?

The IFB-244 Series is an Industrial 2-channel Optical Fiber Bypass Switch that automatically bypasses the local switch in case of power failure, ensuring uninterrupted communication between remote networks.

How does the bypass mode work?

When power is lost, the IFB-244 enters Bypass Mode. The optical traffic is directly routed between the two remote network switches, bypassing the local switch entirely. The state LED turns off to indicate this mode.

What are the available models and their differences?

The series includes IFB-244-SLC and IFB-244-SSC (Single Mode, 1310nm/1550nm) and IFB-244-MLC and IFB-244-MSC (Multimode, 850nm/1300nm). They differ in optic connector type (LC or SC) and fiber mode.

What is the bypass switching time?

The bypass switching time is less than 8 milliseconds, ensuring minimal disruption to network traffic during power events.

What power supply does the IFB-244 require?

It accepts dual 9-48V DC or 24V AC inputs with reverse polarity protection. It is recommended to power it from the same source as the local switch to ensure coordinated bypass.

How do I install the IFB-244?

The device can be mounted on a DIN rail or a wall using the included kits. The manual provides step-by-step instructions for mounting and grounding. Ensure proper grounding to protect against lightning damage.

What is the operating temperature range?

The IFB-244 operates in temperatures from -40°C to 75°C and can be stored from -40°C to 85°C, making it suitable for harsh industrial environments.

How do I connect optical fibers?

Connect the Remote Network ports to the two remote switches and the Local Switch ports to the local switch. Use duplex fibers for standard connections or simplex fibers for WDM/Bi-di applications. Refer to the manual for detailed diagrams.

What do the LED indicators mean?

P1 and P2 (green) indicate power status for each input. FAULT (red) lights if either power fails. Normal (green) is lit in normal mode and off in bypass mode.

Is the IFB-244 compliant with industry standards?

Yes, it complies with FCC Part 15 Class A and CE (EMC Directive 2014/30/EU). It also meets IEC60068-2 standards for free fall, shock, and vibration.

The wire gauge for the terminal block should be in the range from 12 to 24 AWG.

When performing any of the procedures like inserting the wires or tightening the wire-clamp screws, make sure the power is OFF to prevent from getting an electric shock.

5. Hardware Installation

This section describes the functionalities of the Optical Bypass Switch's components and guides you to installing it on the DIN rail and wall. Please read this chapter completely before continuing.

This following pictures guide you to how to install the device, and the device is not IFB-244 Series.

5.1 DIN-rail Mounting Installation

5.2 Wall-mount Plate Mounting

5.3 Side Wall-mount Plate Mounting

5.4 Grounding the Device

Uses MUST complete grounding wired with the device; otherwise, a sudden lightning could cause fatal damage to the device. EMD (Lightning) DAMAGE IS NOT CONVERED UNDER WARRANTY.

6. Optical Fiber and Power Connections

6.1 Optical Fiber Connection

The IFB-244 series is equipped with a total of 4 duplex fiber connectors and they are separated into two groups - Remote Network channels and Local Switch channels.

■ Remote Network group has 2 fiber channels that are used to connect to the other two remote fiber Ethernet switches.

■ Local Switch group has 2 fiber channels that are used to connect to the local fiber Ethernet switch.

■ Connecting to the Remote Network with Duplex Fiber cables

■ Connecting to the Local Switch

■ Connecting to the Remote Network with Simplex Fiber Cables (WDM/Bi-di)

■ Connecting to the Local Switch

6.2 Power Connection

The IFB-244 Series is expected to be powered from the same power source as the Local Switch to ensure power system failure makes the IFB-244 Series change to Bypass mode. Make the IFB-244 Series share the same power source as the Local Switch.

6.3 Recovering Communication from Power Failure

Operation Mode	Power Source	State LED	Optical Traffic Route
Normal Mode	Power on	Normal LED lit on	IFB-244 forwards packets between two remote network switches and the local switch.
Bypass Mode	Power off	Normal LED lit off	IFB 244 directly forwards packets between two remote networks switches and bypass the local switch.
