Installing Fiber Optic Repeaters
Overview Prior to installing 490NRP954 Fiber Optic Repeaters, fiber optic cable must be
installed. Follow the cable manufacturer’s recommendations for routing, installation,
and testing of the cable. Take care when terminating the ends of each fiber optic
cable in order to minimize loss of the optical signal. Follow the manufacturer’s
guidelines for installing optical connectors. Test the cable for proper attenuation
prior to the connection of the fiber optic repeaters.
The cable ends should be accessible at each fiber optic installation site. Allow
sufficient cable length for a service loop and strain reliefs. Label each cable end to
facilitate future maintenance.

Mounting a
Repeater
The 490NRP954 Repeater’s bottom surface is fitted with pads. Brackets for bolting
the unit to a vertical panel are also provided. Your choice of horizontal or vertical
mounting should provide access to the device for observing the LED indicators on
the front panel and to the rear panel connectors for ease of installation and future
servicing.
Horizontal Mounting
To mount the unit on a horizontal surface, place it at or below eye level to allow
viewing the network indicators. Secure it to the surface to prevent it from shifting its
position. Do not allow the unit to pull or strain on the network cables and power
cable. The mounting brackets supplied with the unit for vertical panel mounting can
also be used to secure the unit on a horizontal surface.
Vertical Mounting
CAUTION
Possible Equipment Failure
The RIO network must be powered OFF before installing or replacing a

damage.
