o
Switch. This is designed to provide power to PoE driven devices. The switches operate in a temperature range of 0
and external SFP work. It is suitable for use to build PoE network environment, and SFP slot designed to support a variety of SFP modules,
allowing the construction of Ethernet more flexible.
C to 50oC, supports PoE PSE
Overview
ET24122MPp-S is a 24 ports 10/100Base-TX + 2 ports 10/100/1000Base-T/SFP Managed PoE Ethernet
Switch. The Switch provides the PoE function for kinds of Powered Devices to receive power as well as
data over the RJ-45 cable. 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 0
and at 1U high is designed to be installed in a 19”rack cabinet.

Installation
SFP Transceiver Module
You can select different S FP modules as required (Please refer to our SFP sele c tion list for the
appropriate module).
To insert/remove the SFP, the procedures are as follows :
securely locked.
1. On the front panel, insert the SFP module into the SFP port u ntil it is
2. Connect the optical fiber (1/2 core) to the LC connector(s) of the S FP.
3. To re move the SFP modul e, 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.
