EtherWAN EX78900G Series Installation Manual

Unpacking
Open the carton and unpack the items. Your package should
include:
▪
One EX78900G hardened managed switch
▪
One DB-9 to RJ-45 console cable
▪
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)
cables.
▪
Personal computer or laptop
▪
Appropriate SFP modules for SFP ports
Select a Location
▪
Installations: 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.
▪
Select a power source within 6 feet (1.8 meters).
▪
Choose a dry area with an ambient temperature between -40 and 75°C (-40
and 167°F).
▪
For indoor use, and with an altitude up to 2000 meters.
▪
Humidity range (Operational): 5% to 95%, non-condensation.
▪
Designed in accordance with pollution degree 2.
▪
Do not block the device ventilation holes.
Connect to the Data Ports
Depending on the model, your switch can have the following ports:
4-port 10/100/1000BASE-T(X) PoE++ (90W)
EX78912G-0BT
+ 4-port 10/100/1000BASE-T(X)
+ 2-port 100/1000/2500BASE SFP
8-port 10/100/1000BASE-T(X) PoE++ (90W)
EX78922G-0BT
+ 2-port 100/1000/2500BASE SFP
8-port 10/100/1000BASE-T(X) PoE++ (90W)
EX78924G-0BT
+ 4-port 100/1000/2500BASE SFP
10/100/1000BASE-T(X) (PoE) Ports
Power over Ethernet (IEEE 802.3 af/at/bt PSE standard) ports that supply power
to networked powered devices such as IP phones, wireless LAN access points, and
IP security cameras must all be within the allotted PoE power budget.

100/1000/2500BASE SFP Ports
SFP transceivers can be installed directly into SFP slots. Ensure that the same type
of transceiver is used at both ends of the link and that the correct type of fiber
cable is used.
Connect Power
▪
The switch has two pairs of power inputs. Only one power input is required
to operate the switch. However, redundant power supply functionality is
supported.
▪
Connect the supply voltage to start up the device via the terminal block.
▪
Power rating and consumption
-
Power inputs: 46 – 57 VDC, max. 9.81A
-
System: 13.91 Watts, max. 2.44A
-
System with full-load PoE: 510 Watts, max. 9.81A
-
Power supply selection should align with the power consumption of
powered devices within the system.
