Frequently Asked Questions - High PoE Midspan AXIS

What is the AXIS T81B22 DC 30W Midspan?

It is a Power over Ethernet (PoE) injector that supplies 51 V DC power over spare pairs of Ethernet cabling. It supports both IEEE 802.3af (15W) and 802.3at (30W) standards.

How do I set the power output to 15W or 30W?

Use the Power Selector switch on the device. Set it to 15W for 802.3af devices or 30W for 802.3at devices. The switch must be set before powering on.

What are the input voltage requirements?

The midspan accepts 12 V DC (10.2-14.4 V) or 24 V DC (20.4-28.8 V) from a limited power source (LPS). The input current is up to 3.2 A at 12V or 1.6 A at 24V.

How do I interpret the LEDs?

The Port LED lights steady green for 802.3af (15W), steady yellow for 802.3at (30W). Blinking green/yellow at 1 Hz indicates overcurrent or short circuit; 4 Hz indicates input voltage out of range or internal fault. The DC input LED is steady green when power is connected.

What Ethernet cables should I use?

Use shielded Category 5 or higher straight-wired cables with all four pairs. For 802.3at devices, Category 5e or 6 is recommended. Maximum cable length from Ethernet source to powered device is 100 m for 802.3af, and 70 m (Cat5) or 100 m (Cat5e/6) for 802.3at.

Can I mount the midspan on a wall or DIN rail?

Yes, the AXIS T81B22 can be wall-mounted using rear side holes (screw distance 65 mm vertically) or mounted on a DIN rail. It can also be placed on a bench.

What is the operating temperature range?

The device operates from -20°C to 65°C (-4°F to 149°F) with humidity up to 95% non-condensing. Store between -40°C and 74°C (-24°F to 158°F).

Why is my midspan not powering up?

Check the input voltage is either 12V or 24V DC. Remove and reapply power, then observe the LED indicators. Ensure the power selector is set correctly before power on.

How do I connect the midspan?

Connect a shielded Ethernet cable from your network switch to the Data In port. Connect the Data & Power Out port to your PoE splitter or camera using another shielded cable. Then connect the DC power source to the terminal block.

Is there any safety precaution I should follow?

This product is for indoor use only. Use a limited power source (LPS) with rated output ≤100W or ≤5A. The DC power cable must be rated for at least 3A (0.5 mm², AWG24). Do not connect to a telephone socket. Ensure the product is stored in a dry, ventilated environment.

Mounting instructions

The AXIS T81B22 may be wall or bench mounted using the rear side holes. It can also be mounted on a DIN rail.

Note the following before mounting the AXIS T81B22:

• Do not cover the midspan or block the airflow to the product with any foreign object. Keep the midspan away from excessive heat and humidity, and free from vibration and dust.
• Ensure that the cable length from the Ethernet network source to your Axis video product does not exceed 100 meters (330 feet). See page 9 for information on cable lengths. The midspan is not a repeater and does not amplify the Ethernet data signal.
• Use a splitter if required, but ensure that the splitter is connected close to your Axis video product and not to the Midspan.
• There is no "on-off" switch; simply plug the AXIS T81B22 into a DC power outlet.

To mount:

1. Install two screws vertically at a distance of 65 mm (2.5") on the wall or shelf.
2. Align the AXIS T81B22 mounting slots to capture the surface screws

Troubleshooting

Symptom Corrective steps
Midspan does not power up	1. Verify that the voltage at the power inlet is either 12V DC or 24V DC for Input voltage.2. Remove and re-apply power to the device and check the LED indicators during power up sequence.
A port indicator is not lit and the PD (powered device) does not operate	1. The Midspan did not detect a PD; and the port is not enabled.2. Verify that the PD is designed for PoE operation.3. Verify that you are using a standard Category 5/5e/6, straight-wired cable, with four pairs.4. If there is an external PoE device connected, replace it to verify that it is functioning properly.5. Ensure that the input Ethernet cable is connected to the Data In port.6. Verify that the PD is connected to the Data & Power port.7. Try to reconnect the same PD into a different Midspan. If it works, there is probably a faulty port or RJ-45 connection.8. Verify that there is no shortcut over any of the twisted pair cables or over the RJ45 connectors.
The end device operates, but there is no data link	1. Verify that the port indicator on the front panel is continuously lit.2. If an external PoE device is in use, replace it with a good PoE device.3. Verify that for this link, you are using standard UTP/FTP Category 5 straight (non-crossover) cabling, with all four pairs.4. Verify that the Ethernet cable length is less than 100 meters (333 feet) from the Ethernet source to the powered device. See Ethernet interface, on page 9.5. Try to reconnect the same PD into a different Midspan. If it works, there is probably a faulty port or RJ-45 connection.
