This quick start guide describes how to install and use the 8-port 10/100Base-TX + 2 10/100 /1000Base-T/SFP Combo Managed Ethernet Switch.
o
The switches operate in a temperature range of -10
and SFP slot designed to support a variety of SFP modules, allowing the construction of Ethernet more flexible.
C to 60oC, supports external SFP work. It is suitable for use to build network environment,
Overview
ET8122M-S is a 8 ports 10/100Base-TX + 2 ports 10/100/1000Base-T/SFP Managed Ethernet Switch.
The Switch provides SFP ports to support the use of SFP (Small Form-factor Pluggable) transceiver
module. User can chose different types of SFPs (1000M only). The Switch supports 1 or 2 core
Single-mode or Multi-mode fiber. The product operates at temperatures ranging from -10
DIN-Rail installation.
General
To ensure trouble free transportation and storage, all OT Sys tems products must be tho roughly inspected,
o
C to 60oC and
tested and properly packed before delivery. Check the product upon receipt for any visible damage which
may have been caused during shipment.

2. Connect the optical fiber (1/2 core) to the LC connector(s) of the S FP.
3. To re move the SFP m odule, press down the lock of the LC connector of the
optical fiber to pull out the fiber cable.
4. Pull down the SFP lever and hold its position. Pull out the SFP module
from the SFP port.
Din-rail Mounting
ET8122M-S can be installed on a DIN rail. Ins t al l ati o n st ep s are as follows:
1. First, insert the top of DIN-Rail into the track.
2. Then, lightly push the DIN-Rail into the track.
3. Check if the DIN-Rail is tightened on the track or not.
4. To remove the industrial switch from the track, reverse steps above.

Setup
a) Connect the Ethernet port of the optical Ethernet switch to be used to a PC or network device with a
network cable.
b) Insert the appropriate SFP into the corresponding SFP port. Connect the fiber cable from the remote
device (media converter or switch) to the LC connector of the SFP.
c) After the device is powered on, th e PW R indicator will all be on. If the indicators are not on, check the
power supply connection.
d) After all cables are correctly connected, the indicators will be lit as per port status LEDs (page 8).
Connecting to the Console Port
The supplied cable which one end is RS-232 connector and the other end is RJ-45 connector. Attach the
end of RS-232 connector to PC or terminal and the other end of RJ-45 connector to the console port of
the switch. The connected terminal or PC must support the terminal emulation program.

Login in the Console Interface
When the connection between Switch and PC is ready, turn on the PC and run a terminal emulation
program or Hyper Terminal and configure its communication parameters to match the following default
characteristics of the console port:
Baud Rate: 115200 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Flow control: None
The settings of communication parameters
Having finished the parameter settings, click ‘OK’. When the blank screen shows up, press Enter key to
have the login prompt appears. Key in ‘ admin’ ( default value) for User name and ‘system’ for Password
(use Enter key to switch), then press Enter and the Main Menu of console management appears. Please
see below figure for login screen.
