Port Connection Warnings and Tips
• Keep the UTP cable length to less than 100m.
• If you need to replace an SFP uplink transceiver module while the system is operating, deactivate
the port first and then replace the transceiver module in order to avoid a system malfunction.
• This product uses lasers to transmit signals via its SFP uplink ports. These laser beams are Class
1-compliant beams that pose no threat to human eyes if operating normally. It is, however,
recommended that you do not look directly into the ports while the system is powered on.
• Do not remove the optical cable's rubber cover until it's time to connect it to the product. The
cover protects the cable from contamination.
• If using a dual-core SFP module, make sure that the user's RX port is connected to the target
device's TX port and the user's TX port is connected to the target device's RX port.
• Only use category 5 or 6 UTP cables with RJ-45 connectors to connect to the system's
10/100/1000BASE-T ports. The system's ports can automatically distinguish between MID and
MDIX connectors, so there is no need to use a crossover cable when connecting to a different
device's TX port.
• The system's RJ-45 uplink ports may be used as service ports, but they do not support PoE.
• The connection distance can be extended to 500m to 10km using fiber optic cables. The
maximum distance may vary depending on the SFP module being used.
• To ensure safety, choose optical cables with a maximum operating temperature equal to or higher
than the system's maximum operating temperature (50°C).
• Keep the ports clean. Port contamination can hinder optical signal transmission. Use a dab of
ethanol on a clean tissue or q-tip and gently clean the ports.
