Hot Swappable Power Supplies (3G+ Rack-Mount Only)
The 3G+ Rack Mount units are equipped with dual hot-swappable, current sharing power supply
modules. Each module has an ON/OFF rocker-type power switch. When the power supply is ON
the LED on the front of the power supply will be lit.
Note: If no modules are plugged in but both power supplies are powered “On”
the front LED status may flash or malfunction, giving you an inconclusive reading
of power supply status for the unit. An uninstalled power module will not report an
alarm.
In the unlikely event that a power module fails, the replacement can be swapped with no
interruption in unit functionality. To hot swap a power supply, simply unscrew the failed module
and replace it with a new power supply module (part number VTM-000001, which can be ordered
from Thinklogical™).

Fiber Optic Cable
Fiber optic cable must run between the Transmitter unit and the Receiver unit. The multi-mode
fiber optic cable must be 50 microns, terminated with a LC-type fiber optic connector and no longer
than 3280 running feet (1000 meters). Single-mode fiber can extend to distances beyond 1000m.
Unlike copper cabling, fiber optic cable requires special handling. A small speck of
dust or a scratch to the ferrule tip can attenuate the optical signal, making the fiber cable
unusable.
Warning! The ends of the connectors (the ferrule) should never come in contact
with any foreign object, including fingertips.
Warning! Minimum bend radius must be 3”. Be careful not to pinch the fiber
when using ties.
