▪Appropriate fiber cable for fiber ports
3Select a Location
▪Installation: DIN rail. Place the device on the DIN
rail from above using the slot. Push the front of
the device toward the mounting surface until it
audibly snaps into place.
▪Choose a dry area with ambient temperature
between -10°C to +60°C (14°F to 140°F).
▪Keep away from heat sources, sunlight, warm air
exhausts, hot-air vents, and heaters.
▪Be sure there is adequate airflow.
▪This device has been evaluated for conformity for
use in a business environment. If used in a home
environment, there is a danger of interference.
4Connect to the Data Ports
Depending on the model, your switch can have the
following ports:
▪16 10/100Base-TX Ports
▪15 100Base-FX Port + 1 100BASE-FX port
▪14 100Base-FX Port + 2 100BASE-FX ports
5Connect Power
The switch has two pairs of power inputs:
▪A 12-48VDC terminal block
▪A 12VDC jack
Only one power input is required to operate the
switch. However, redundant power supply
functionality is supported.
Terminal Block
The switch provides two power inputs on a 12-48VDC
terminal block. The terminal block has 5 terminal
posts.
Power Failure Alarm
A 2-pin terminal block is provided for power failure
detection. Do not connect a power source to these
pins.
The relay contact closes if:
▪Power 1 and Power 2 are both failed, but Power 3
is ON.
▪Power 3 is failed, but Power 1 and Power 2 are
both ON.
Power-Up Sequence
When the switch is powered up:
▪All Link/ACT LEDs blink momentarily.
▪The Power LED lights up and stays lit.
▪LEDs for every port connected to a device will
flash, as the switch conducts a brief Power On Self-
Test (POST).
