This guide serves the following
ComNet Model Numbers:
CNGE11FX3TX8MS
CNGE11FX3TX8MSPOE
CNGE11FX3TX8MSPOEHO
The ComNet CNGE11FX3TX8MS[POE][HO] has three 100/1000Base-FX SFP ports
and eight 10/100/1000Base-TX ports. Two of the SFP ports support 2.5 Gbps
SFPs for high speed communication in bandwidth intensive applications. All SFP
ports utilize ComNet SFP modules for fiber and connector type and distance. The
IEEE802.3-compliant unit offers multiple Ethernet redundancy protocols (MSTP/RSTP/
STP/ERPS (G.8032)) which protect your applications from network interruptions or
temporary malfunctions by redirecting transmission within the network. The switch
provides advanced IP-based management that can limit the maximum bandwidth
for each connected IP device, allowing the user to adjust usage. Two models are
available which supply Power over Ethernet (PoE). The CNGE11FX3TX8MSPOE
model provides eight electrical ports supporting up to thirty watts of power. On the
CNGE11FX3TX8MSPOEHO model, four of the eight PoE ports can support up to sixty
watts of PoE power. All PoE ports are IEEE802.3at compliant.

Each switch has another installation method for users to fix the switch. A wall mount panel can be
found in the package. The following steps show how to mount the switch on the wall:
Mounting the CNGE11FX3TX8MS on a Wall
Step 1: Remove DIN-Rail kit if it is installed.
Step 2: Remove the two screws at the top of the unit’s back panel. Remove only one pair of back
panel screws at time (these hold the back panel in place on the unit).
Step 3: Use the same two screws plus one of the included screws to attach the wall mount panel to
the top set of screw holes as shown in the diagram below.
Step 4: Repeat Steps 2 and 3 to mount the second wall mount panel on the bottom of the unit’s
back panel.
ATTENTION: Do not remove the top and bottom panel screws at the same time, or the back
panel will detach from the unit. Install the wall mount panels one at a time.
In order to prevent switches from being damaged, the screws should match the size screws that
comes pre-installed in the CNGE11FX3TX8MS switch (M3 × 8 mm).

About Web-based Management
An embedded HTML web site resides in the flash memory on the CPU board. It contains
advanced management features and allows you to manage the switch from anywhere on the
network through a standard web browser such as Microsoft Internet Explorer.
The Web-Based Management function supports Internet Explorer 5.0 or later. It is based on Java
Applets with an aim to reduce network bandwidth consumption, enhance access speed and
present an easy viewing screen.
Note: By default, IE5.0 or later version does not allow Java Applets to open sockets. You need to
explicitly modify the browser setting in order to enable Java Applets to use network ports.
