Install the device
Preparations
– Rack mounting: ESD bracelet or gloves, screwdriver, 4 screws (suitable for
securing the switch to the rack)
– Desktop mounting: ESD bracelet or gloves
– Wall mounting: ESD bracelet or gloves, screwdriver, spirit level, marker,
hammer drill, rubber hammer, ladder, 4 screws (self-prepared, thread diameter:
5 mm, length: 25 mm; Head diameter: 10 mm), 4 expansion bolts (self-prepared,
thread diameter: 5 mm, length: 40 mm)
Rack mounting (to a standard 19-inch rack)
- Ensure that the rack is stable, level and properly grounded
- Fix the two L-shaped brackets to both sides of the switch with the included screws.
- Choose a proper height and fix the L-shaped brackets to the rack with screws (self-prepared). Ensure that the switch is stable on the rack.
Desktop mounting
Paste the four footpads to the four recesses on the bottom of the switch.
Then horizontally place the switch right-side up on a big enough, clean,
stable and flat desktop. 
Wall mounting
Note
– The switch can only be installed on non-flammable walls, such as a concrete
wall.
– Do NOT install the swiitch with air vents facing downward; otherwise, there
will be potential safety hazards.
- Fix the two L-shaped brackets to both sides of the switch with the included screws.
- Place the switch horizontally onto the wall with its RJ45 ports facing upward, and then mark the screw holes on the wall with a marker.
- Drill holes in the marked positions, and then hammer the expansion bolts (self-prepared, specifications see Preparations) into the holes.
- Insert the screws (self-prepared, specifications see Preparations) through the holes of the two L-shaped brackets, and secure the screws into the expansion bolts with a screwdriver. Ensure that the switch s installed firmly with its RJ45 ports facing upward.
Typical network topologies
Tips:
– The SFP port on the switch is an independent SFP port
– The switch supports auto MDI/MDIX. You can connect the switch to Ethernet
devices by using either a straight-through cable or a crossover cable.
– To protect the switch from overload, POE ports of your switch are assigned
with power supply priorities, and the priorities decrease as the port number
increases. When the total power consumption of the PoE-powered devices
‘exceeds the maximum output of the switch, the switch starts cutting the power
supply from the port with the lowest priority, until the total consumption
does not exceed the maximum output.

Working mode toggle
| Working mode | Description |
|---|---|
| Defauit | Default mode. In this mode, al ports can communicate with each other. |
| Priority | In this mode, ports 1 to 8 are high-priority ports. All ports can |
communicate with each other
When using this mode, you are advised to connect Ethernet devices (such as IP
cameras and AP5) in critical areas to higher-priority ports to ensure that
critical services are prioritized when network congestion occurs.
Extend| In this mode, the working status of each switch is as follows:
– For TEG1120P-16-250W and TEG1120P-16-150W: The maximum
transmission distance of 9 to 16 ports can reach 250 meters, and all ports can
communicate with each other.
– For TEG1128P-24-410W and TEG1128P-24-250W The maximum transmission distance
of 17 to 24 ports can reach 250 meters, and all ports can communicate with
each other.
VALN| In this mode, the working status of each switch is as follows:
– For TEG1120P-16-250W and TEG1120P-16-150W: Ports 1 to 16 cannot communicate
with each other, but can communicate with ports 17,18, SFP1, and SFP2.
– For TEG1128P-24-410W and TEG1128P-24-250W. Ports 1 to 24 cannot communicate
with each other, but can communicate with ports 25, 26, SFP1, and SFP2.
This mode can be used to reduce broadcast storms and isolate DHCP broadcasts.
