Step 3: Install 675R/T
Install 675R/T using one of the following methods:
• Attach the rubber feet and place the unit on a flat surface.
• Fasten a bracket (included) on each side of the unit and attach it to a flat surface
(see www.kramerav.com/downloads/675R/T).
• Mount the unit in a rack using the recommended rack adapter
(see www.kramerav.com/downloads/675R/T).
• Ensure that the environment (e.g., maximum ambient temperature &
air flow) is compatible for the device.
• Avoid uneven mechanical loading.
• Appropriate consideration of equipment nameplate ratings should be
used for avoiding overloading of the circuits.
• Reliable earthing of rack-mounted equipment should be maintained.
• Maximum mounting height for the device is 2 meters.
Step 4: Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your 675R/T. For best results, we recommend that you
always use Kramer high-performance cables to connect AV equipment to 675R/T.
Make sure that you always cross-connect the fiber connections, Rx OUT to Tx IN and Rx IN to Tx OUT, as unidirectional optical
transmission is carried on simplex fiber strands.
To install/replace the OSP-MM1 or other Kramer recommended SFP+
transceiver:
1. Pull the bail out and remove the currently installed transceiver,
insert the protective cap and store in a safe place.
2. Make sure the bail of the new transceiver is pushed up, in the
closed position.
3. Insert the new transceiver into the relevant optical device SFP+ slot
and push it in until it clicks.
4. Remove the protective cap and store it in a safe place for future
use.
Warning: Connecting the SFP+ transceiver to an LC(APC) fiber
connector may cause poor performance and damage the connector!
Refer to www.kramerav.com/downloads/OSP-MM1 for more information.
Warning: Class 1 Laser Product
• Invisible laser radiation present.
• Avoid long-term viewing of laser.
• Avoid the use of magnifying viewing aids or instruments (such as binoculars, telescopes, microscopes and
magnifying lenses, but not spectacles or contact lenses).
• Avoid placing optical devices in the emitted beam that could cause the concentration of the laser radiation to be
increased.
Step 5: Connect the power
Connect the power cords to 675T and 675R and plug into the mains electricity.
Safety Instructions (See www.kramerav.com for updated safety information).
Caution:
• There are no operator serviceable parts inside the unit.
Warning:
• Use only the power cord that is supplied with the unit.
• Disconnect the power and unplug the unit from the wall before installing.
