Ethernet Router
Model: ER-X
EdgeRouter X Power Adapter
(12V, 0.5A)
Installation Requirements
• For indoor applications, use Category 5 (or above) UTP
cabling approved for indoor use.
• For outdoor applications, shielded Category 5 (or above)
cabling should be used for all wired Ethernet connections.
To enhance ESD protection, attach a ground wire (not
included) to the back panel of the EdgeRouter X.
We recommend that you protect your networks
from harmful outdoor environments and destructive
ESD events with industrial‑grade, shielded Ethernet
cable from Ubiquiti Networks. For more details, visit:

WARNING: To reduce the risk of fire or electric shock, do
not expose the EdgeRouter X to rain or moisture.
Note: Although the cabling can be located outdoors,
the EdgeRouter X itself should be housed inside a
protective enclosure.
TERMS OF USE: All Ethernet cabling runs must use CAT5 (or above). It is the professional
installer’s responsibility to follow local country regulations, including operation within legal
frequency channels, output power, indoor cabling requirements, and Dynamic Frequency
Selection (DFS) requirements.

RJ45 port accepts 24V passive PoE
and supports a 10/100/1000 Ethernet
connection.
RJ45 ports support 10/100/1000 Ethernet
connections.
RJ45 port supports passive PoE passthrough
and a 10/100/1000 Ethernet connection.
Passive PoE Passthrough
The EdgeRouter X can be powered by either method:
• Power adapter
• 24V passive PoE on the eth0/PoE Inport
Passive PoE output on port eth4/PoE Out works as a
passthrough and depends on the input power source.
If the included Power Adapter (12V, 0.5A) is used, there may not
be sufficient passthrough to power another device because
the EdgeRouter X can consume up to 5 watts on its own.
We recommend using a more powerful input power source
(not included); here are a few examples of viable power input
options for passive PoE passthrough:
Power Input Passive PoE Passthrough
24V passive PoE (on eth0/PoE In)* ≈23V, 5W
12V, 1A
(ERLite‑3 Power Adapter)
24V, 2.5A
(ERPoe‑5 Power Adapter)
≈11V, 5W
≈23V, 11W
* Not compatible with 24V, 1A Gigabit PoE Adapter.

and the EdgeRouter X will automatically
Reset
reboot.
Power‑on Reset
1. Disconnect the Power Adapter from the
EdgeRouter X.
2. Press and hold the Reset button while
connecting the Power Adapter to the
EdgeRouter X. Keep holding the button
until the eth4 LED starts flashing and then
stops flashing after a few seconds.
