EtherWAN TG103H Installation Manual

Unpacking

Open the carton and unpack the items. Your package should include:
▪
One TG103H Switch
If any items are missing or damaged, notify your EtherWAN representative. If
possible, save the carton and packing material in case you need to ship or store
the switch in the future.

Equipment Needed

▪
Appropriate cables for data ports. To prevent damage to the switch from
electrical surges, it is recommended to use STP (Shielded twisted pair) cabling
with a minimum rating of cat5e.
▪
Appropriate SFP modules for SFP ports

Select a Location

▪
Installation: Place the device on the DIN rail from above using the slot. Push
the front of the device toward the mounting surface until it audibly snaps into
place.
▪
Choose a dry area with an ambient temperature between -40°C to 75°C (-
40°F to 167°F).
▪
Keep away from heat sources, sunlight, warm air exhausts, hot-air vents, and
heaters.
▪
Be sure there is adequate airflow.
▪
Pollution degree 2.

Connect to the Data Ports

The switch has the following ports:
TG103H-0802 8 Gigabit PoE ports + 2 100/1G SFP ports

Connect Power

The switch has two power inputs. Only one power input is required to operate
the switch. Connect the supply voltage to start up the device via the terminal
block.
Power rating:
▪
PoE 30 Watts per port: 52–57 VDC, 5.47-4.99 A
▪
PoE 90 Watts per port: 54–57 VDC, 5.17-4.99 A
▪
PoE power budget: 270W
▪
The power input specification complies with the requirements of SELV (Safety
Extra Low Voltage), and the power supply should comply with UL 61010-1
and UL 61010-2-201.

Terminal Block

The switch provides two power inputs on a 52-57VDC terminal block.

Relay Output Alarm

The switch provides a relay output contact. The relay is used to indicate a user-
defined power redundancy failure. The current is 0.5A@48VDC at Normally Open
or Normally Closed.

Power-Up Sequence

When the switch is powering up:
▪
All Link/ACT LEDs blink momentarily.
▪
The Power 1, 2 LEDs light up and stay lit.
▪
LEDs for every port connected to a device will flash, as the switch conducts a
brief Power On Self-Test (POST).

Quality of Service (QoS)

The QoS feature is automatically activated when the switch is running. Priority
mapping is handled according to the following tables:
CoS priority
7, 6 5, 4
(802.1p)
DSCP priority 59, 55 47, 46, 43
Queues 3 2

EtherNet/IP: UDP 2222 (Queue 2)
Profinet Ether type: 0x8892 (Queue 2)

DIP Switch Settings

There is a 10-pin DIP switch for enabling the PoE Watchdog function.
When the DIP switch for a port is set to ON, the watchdog function will be
enabled after the device has been powered on for 10 minutes to give powered
devices time to boot. Every 30 seconds, the device will detect whether the
packets from a powered device are being received or not. If no packet is received
after 30 seconds, connected ports with the DIP switch set to ON will be restarted
(other ports are not disturbed). If a packet is received in the 25th second, then
the 30 second interval will be restarted.
If DIP switch 9 (EXT) is set to ON, the watchdog function will be enabled after 5
minutes instead of 10 minutes after the switch powers on.
