Universal programmable PoE injector (P/N I0ATPI24/I0ATPI44)
The I0ATPI24 and I0ATPI44 injectors are designed to operate with any PoE-capable product
with a Fast Ethernet / Gigabit Ethernet interface. Built-in protection conforms to the IEC
61000-4-5 standard.
The accepted input voltage is 20
…
65VDC. The output voltage is stabilized to 54VDC.
Interconnection scheme:
The front panel has 3 indication LEDs. LED3 indicates the position of DIP switch S1. Color
indication of all LEDs must be ignored in Forced mode (DIP switch S4 in DOWN position).
Load detected and voltage fed at the
output of PoE injector (POWER GOOD)
No load at the output of the PoE injector
(OPEN)
PoE controller detected and voltage fed
at the output of PoE injector (POWER
ON)
Short at the output of PoE injector
(SHORT)
Auto PoE mode if S4 is UP; see table
below.
Manual PoE mode if S4 is UP; see table
below.
The back panel has 4 switches to operate the PoE injector in different modes.
The appropriate I
max
selection, while manual PoE mode is enabled (S1 UP, S4 UP), will
provide the most effective surge protection for the radio. In case I
max
exceeds the set value,
upper LEDs (LED1&LED2) will blink in green color.
Connecting a device in Manual or Forced modes will introduce approx. 5-second delay of
LED indication.
In case of Auto PoE mode is enabled (S1 position DOWN, S4 position UP) I
max
mode (PD
class) is negotiated automatically with the device connected.
The position of DIP switches should be changed only while the PoE injector is turned off.
