EtherWAN OttoE TG103 Series Installation Manual

Unpacking

Open the carton and unpack the items. Your package should include:
▪
One OttoE TG103(H) Switch. Note that the (H) indicates hardened models.
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.
▪
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 -10 and 60ºC (-14
and 140ºF).
▪
Choose a dry area with an ambient temperature between -40°C to 75°C (-
40°F to 167°F) for H models.
▪
Keep away from heat sources, sunlight, warm air exhausts, hot-air vents, and
heaters.
▪
Be sure there is adequate airflow.
▪
The product is indoor use only.
▪
Pollution degree 2.

Connect to the Data Ports

Depending on the model, your switch can have the following ports:
TG103(H)-0800 8 Gigabit PoE ports
TG103(H)-0802 8 Gigabit PoE ports + 2 100/1G SFP ports
4 Gigabit PoE ports + 4 Gigabit TX ports + 2 100/1G SFP
TG103(H)-0442
ports

Connect Power

The switch has two pairs of 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
▪
Total PoE max.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.

Power-Up Sequence

When the switch is powered 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
(802.1p)
DSCP priority
Queues
WFQ
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 Watchdog (WDG) function.
When the DIP switch for a port is set to ON, the WDG function will be enabled
after the TG103(H) has been powered on for 10 minutes to give powered devices
time to boot. Every 30 seconds WDG will detect whether the packets from a
powered device are being received or not. If no packet is received after 30
seconds, the powered device will be restarted and only the connected port with
the DIP switch set to ON will be restarted (other ports are not disturbed). If the
packet is received in the 25th second, then the 30 seconds interval will be
restarted.
If DIP switch 9 (EXT) is set to ON, the WDG function will be enabled after 5
minutes instead of 10 minutes after the switch powers on, to accommodate
faster booting powered devices.
