CNGE3FE8MS[POE][HO]
Environmentally Hardened Managed Ethernet Switch
3 SFP + 8 Electrical Ports with Optional 30 or 60 Watt PoE
The ComNet CNGE3FE8MS[POE][HO] has three 100/1000Base-FX SFP ports and eight
10/100Base-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 CNGE3FE8MSPOE model provides eight electrical ports
supporting up to thirty watts of power. On the CNGE3FE8MSPOEHO model, four
of the eight PoE ports can support up to sixty watts of PoE power. All PoE ports are
IEEE802.3at compliant.

Safety Information
»Only ComNet service personnel can service the equipment. Please contact ComNet Technical
Support.
»The equipment should be installed in locations with controlled access, or other means of
security, and controlled by persons of authority. When operating at temperatures above 51º C, the
equipment surfaces will be hot to the touch. Installation in restricted access location is required
for this case.
»For POE models requiring a power supply not labeled LPS, the unit should be installed in a
restricted access location using a 60950-1, 2nd Edition + Am. 1 + Am. 2 Certified power supply
rated for the ambient temperature in which it is installed. Total derated power rating should be
greater than the sum of the attached loads plus 15 W for the switch.
»Use CDRH compliant SFP modules when using fiber connectivity with this device.
»When used in Australia or New Zealand, the product is certified for intra building applications
only, and should not be directly connected to network cables with outside plant routing.

Hardware Installation
Installing the Switch on DIN-Rail
Each switch has a Din-Rail kit on the rear panel. The DIN-Rail kit affixes the switch to the DIN-Rail.

TECH SUPPORT: 1.888.678.9427
It is easy to install the switch on the Din-Rail:
Mount Series on DIN-Rail
Step 1: Tilt the switch and mount the metal spring to DIN-Rail.
Step 2: Push the switch toward the DIN-Rail until you hear the spring snap into place
.

Wall Mounting Installation
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 switch on a wall
Note: For drywall applications where no studs are available, use drywall anchors rated for 50 lbs
or more.
In order to prevent switches from being damaged, use appropriate hardware (not supplied)
for securing the unit to the wall.
#6 screws with at least ½-inch penetration into wood surface recommended.
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.
When operating at temperatures above 51ºC, the equipment surfaces will be
hot to the touch. Installation in restricted access location is required for this case.

IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an environment compatible with
the maximum ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air
flow required for safe operation of the equipment is not compromised.
