AXIS T8125 AC 24 V Midspan 60 W
Functions and Features
The high-power Gigabit single-port PoE (Power over Ethernet)
AXIS T8125 Midspan injects power over data-carrying Ethernet
cabling. It maintains the IEEE802.3at draft 3.2 and IEEE802.3af standard,
while doubling the output power (60 W). The AXIS T8125 DATA &
POWER Output port is designed to carry Gigabit Ethernet data & power
over a standard CAT5e cable or higher, delivered through all 4-pairs:
• Alt A: pins 1, 2 (-) & 3, 6 (+)
• Alt B: 4, 5 (+) and 7, 8 (-)
Preliminary Steps
• Ensure that 24 V AC is applied to the AXIS T8125. Use cables of 12
AWG for each terminal or 2X16 AWG for each terminal, with an
appropriate separate ground connection (when needed).
• Ensure that the output Ethernet cable is connected to the
DATA & POWER OUT port.
• Verify that a power-ready Ethernet compatible device is connected.
• Do not cover the AXIS T8125 or block the airflow to the PoE with
any foreign objects. Keep the AXIS T8125 away from excessive heat
and humidity, and free from vibration, dust and direct sunlight.
• Ensure that the cable length from Ethernet network source to the
terminal does not exceed 100 meters (333 feet). The AXIS T8125 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 the terminal and not on the AXIS T8125.
• No "on-off" switch exists; simply plug the AXIS T8125 into a
24 V AC power source.
Caution!
Do not use cross-over cable between the AXIS T8125
Output port and the load device.
