3 Precautions for shipping
The MM / SM model (NJR-T01SDI-MM / SM) has an SFP+ optical transceiver that makes it vulnerable to
damage caused by mishandling during shipment if it is improperly packaged.
If, for any reason, you need to ship the NJR, use the carton and cushion which were used at the time of
purchase. Make sure to plug the attached dust cap into the SFP+ optical transceiver. If you do not have the
carton and cushion, unplug the SFP+ optical transceiver from the NJR and plug the dust cap, and then put it
in an antistatic bag with enough cushion. Use the appropriate carton and cushion for shipping.

8 Precautions
Before using NJR-T01SDI, follow the precautions and instructions below.
8.1 Attaching Rubber feet
First, clean the bottom surface of the NJRT01SDI as needed, and then peal the release papers from the
rubber feet and place them in each of the four corners.
8.2 Installation
When installing the NJR-T01SDI, please observe the following precautions.
・Do not stack or place one NJR-T01SDI directly on top of another NJR-T01SDI.
・Do not block vent holes. To provide adequate ventilation, maintain sufficient clearances around the
NJR-T01SDI (1.2 in. (30 mm) or more).
・Do not install NJR-T01SDI in a closed space.
When placing them in an EIA rack-mount unit, prepare ventilating equipment to keep the ambient
temperature at 40°C / 104°F or less. If inadequately vented, the life of parts may be shortened and
operation may be affected.
(Exception: Installing to IDK’s rack mounting RM-SF, RM-SH)
・When you do not use an EIA rack-mount unit, maintain adequate clearances (1.2 in. (30 mm) or more) as
shown below.

8.3 Cabling
When connecting the NJR-T01SDI to external devices, please observe the following precautions.
・Read manuals for the external devices.
・Before connecting cables to the NJR or an external device, dissipate static electricity by touching
grounded metal such as equipment racks before handling signal cables. Failure to observe this
precaution may result in ESD (electrostatic discharge) damage.
・Power all units off before connecting cables.
・Be sure to fully seat all plugs and connections and dress cables to reduce stress on connectors.
・Secure HDMI cables using cable clamps to prevent connectors from being accidently pulled out of ports.
