How to install TRENDnet TPE-TG81g

• Choose a suitable mounting location. If you plan to rack-mount the switch, use the included or compatible rack ears and secure the unit in a standard 19-inch rack to ensure stability and proper airflow.
• Power the switch using the internal power supply. Connect the power cord to a grounded outlet and verify that the LED indicators illuminate, signaling normal startup.
• Connect the uplink or core network device (such as a router or another switch) to one of the Gigabit Ethernet ports on the TPE-TG81g using a Cat5e (or better) Ethernet cable. This establishes the path for data to enter and exit the PoE network.
• Power on your PoE-enabled devices (IP cameras, access points, VoIP phones, etc.) and connect them to the remaining PoE+ ports on the switch. The switch will automatically negotiate power and data speeds with each device, providing up to 30W per port where required and within the 110W total budget.
• Test connectivity and performance. Since this is an unmanaged switch, there is no software configuration required. Confirm that connected devices obtain network access and that PoE devices power on reliably. If you encounter any issues, verify cable integrity, port connections, and the total PoE consumption to ensure you stay within the 110W budget.
• Optional: For organized installations, use cable management practices to route cables neatly and maintain adequate ventilation around the switch to prevent overheating in dense rack environments.

Frequently asked questions

• Q: Does the TRENDnet TPE-TG81g support IEEE 802.3af/at PoE+ on all ports?
• A: Yes. Each port supports PoE+, delivering up to 30W per port, with a total PoE budget of 110W for the entire switch.
• Q: Is this switch unmanaged or does it require configuration?
• A: The TPE-TG81g is an unmanaged PoE+ switch. It is designed for plug-and-play deployment with no required configuration, making it ideal for quick installations and straightforward network expansion.
• Q: Can I rack-mount this switch?
• A: Yes. The switch features a metal chassis and includes rack-mount capability, allowing it to be securely installed in standard 19-inch racks for professional network setups.
• Q: How does GREENnet help with energy efficiency?
