Safety information (for AXIS High PoE
Midspan only)
Installation and removal of the AXIS High PoE
Midspan must be carried out by qualified
personnel only.
• AC Power Cable Set:
• The power cable must have regulatory agency
approval for the specific country in which it is used
(for example, UL, CSA, VDE).
• The power cable must be a three-conductor type
(two current carrying conductors; one ground
conductor) terminated on one end by an IEC 60320
appliance coupler (for connection to the AXIS High
PoE Midspan), and on the other end by a plug
containing a ground (earthing) contact.
• The power cable must be rated for a minimum of
250Vac RMS operation, with a minimum rated
current capacity of 5 amps (or a minimum wire
gauge of 18 AWG (0.75mm
2
).
• Note: AXIS High PoE Midspans installed in Australia
require power cables with a minimum wire gauge of
16 AWG (1.0 mm2).
• The AC wall socket-outlet must be near the AXIS High
PoE Midspan and easily accessible. You can remove AC
power from the AXIS High PoE Midspan by
disconnecting the AC power cable from either the wall
socket-outlet or the AXIS High PoE Midspan appliance
coupler.
• The AXIS High PoE Midspan data and data/power
interfaces are qualified as SELV (Safety Extra-Low
Voltage) circuits according to IEC 60950. These
interfaces can only be connected to SELV interfaces on
other equipment.
WARNING!
• Read the installation instructions before connecting
the AXIS High PoE Midspan to its power source.
• Follow basic electricity safety measures whenever
connecting the AXIS High PoE Midspan to its power
source.
• A voltage mismatch can cause equipment damage
and may pose a fire hazard. If the voltage indicated
on the label is different from the power outlet
voltage, do not connect the AXIS High PoE Midspan
to this power outlet.
• This product relies on the building installation for
short-circuit (over current) protection. Ensure that a
fuse or circuit breaker no larger than 120 VAC, 3A.
U.S. (240 VAC, 1.5A international) is used on the
phase conductor.
• The AXIS High PoE Midspan "Data In" and "Data &
Power Out" ports are shielded RJ-45 data sockets.
They cannot be used as Plain Old Telephone Service
(POTS) telephone sockets. Only RJ-45 data
connectors may be connected to these sockets.

Functions and features
The AXIS T8121 High PoE Midspan 1-port injects 48V DC power into data-carrying Ethernet cabling.
It maintains IEEE802.3af specification parameters while doubling the output power. These power
levels allowed a new range of Ethernet-based applications such as PTZ Cameras to use the High PoE
Midspan.
Preliminary steps
• Ensure AC power is applied to the AXIS T8121, using an operational AC cable with appropriate ground connection.
• Ensure that output Ethernet cable is connected to the Data & Power Out port.
• Verify that a power ready Ethernet compatible device or splitter is connected.
ENGLISH
Note:
Do not use a cross over cable between the AXIS T8121 output port and the powered device.

Troubleshooting
Symptom Corrective steps
Midspan does not power up 1. Verify that an approved power cable is used.
2. Verify that the voltage at the power inlet is between 100 and
240V AC.
3. Remove and re-apply power to the device and check the
indicators during power up sequence.
A port indicator is not lit and the PD
(powered device) does not operate
The end device operates, but there is
no data link
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, straightwired cable, with four pairs.
4. If there is a connected external power splitter, 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.
1. Verify that the port indicator on the front panel is continuously
lit.
2. If an external power splitter is in use, replace it with a known
good splitter.
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 (33
feet) from the Ethernet source to the powered device.
5. Try to reconnect the same PD into a different Midspan. If it works,
there is probably a faulty port or RJ-45 connection.

Mounting instructions
The AXIS T8121 may be wall or bench mounted using the rear side holes.
Note the following before mounting the AXIS T8121 to a fixed location:
• 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 (333 feet). The midspan is not a repeater and does not amplify
the Ethernet data signal.
• Use a splitter if desired; 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 T8121 into an AC power outlet.
To mount:
1. Install two screws vertically at a distance of 9.17 cm (3.61”) on the wall or shelf.
2. Align the AXIS T8121 mounting slots to capture
the surface screws.

Fonctions et caractéristiques
L´injecteur AXIS T8121 High POE 1 port injecte une alimentation de 48V DC aux travers du cable
Ethernet. La norme IEEE802.3af est maintenue tout en doublant la puissance de sortie. Ces niveaux
de puissance permettent de nouvelles possibilités comme l´alimentation de cameras PTZ AXIS par
l´intermérdiaire d´injecteurs High PoE.
Étapes préliminaires
• Vérifiez que l'injecteur AXIS T8121 est raccordé à un câble CA en bon état de
fonctionnement et correctement mis à la terre.
• Vérifiez que le câble Ethernet de sortie est branché sur le port Data & Power Out
(données et d'alimentation de sortie).
• Vérifiez qu'un périphérique compatible Ethernet prêt à être branché est connecté.

Résolution des problèmes
Symptôme Correction
L'injecteur ne se met pas sous tension.
Un indicateur de port est éteint et le
périphérique ne fonctionne pas.
Le périphérique final
fonctionne, mais il
n'y a pas de liaison
de données.
1. Vérifiez qu'un cordon d'alimentation approuvé est utilisé.
2. Vérifiez que la tension à l'arrivée se situe entre 100 et 240 V CA.
3. Mettez l'injecteur hors tension et rallumez-le en vérifiant les
indicateurs pendant la mise sous tension.
1. L'injecteur n'a pas détecté de périphérique. Le port est donc
désactivé.
2. Vérifiez que le périphérique prend en charge la technologie PoE.
3. Vérifiez que vous utilisez un câble droits ordinaire de catégorie 5/
5e/6, à quatre paires.
4. Si un diviseur d'alimentation externe est utilisé, remplacez-le
pour vous assurer qu'il fonctionne correctement.
5. Vérifiez que le câble Ethernet d'entrée est branché sur le port de
données d'entrée.
6. Vérifiez que le périphérique est branché sur le port de données et
d'alimentation.
7. Essayez de rebrancher le périphérique sur un injecteur différent.
S'il fonctionne, il est probable que le port ou le connecteur RJ-45
soit défectueux.
8. Vérifiez qu'il n'y a pas de court-circuit sur les câbles à paires
torsadées ni sur les connecteurs RJ45.
1. Vérifiez que l'indicateur de port à l'avant de l'appareil est allumé
en continu.
2. Si un séparateur d'alimentation externe est utilisé, remplacez-le
par un séparateur que vous savez en bon état de fonctionnement.
3. Vérifiez que, pour cette liaison, vous utilisez un cable droit UTP/
FTP ordinaire de catégorie 5 (et non un cable simulateur de
modem), avec les quatre paires.
4. Vérifiez que le câble Ethernet ne fait pas plus de 100 mètres de
long entre la source Ethernet et le terminal distant.
5. Essayez de rebrancher le périphérique sur un injecteur différent. Si
cela fonctionne, il est probable que le connecteur RJ-45 soit
défectueux.
