CNGE3FE8MSPOEHO
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.

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.

Green Ethernet
LED
Object Description
LEDs Intensity The LEDs power consumption can be reduced by lowering the LEDs intensity. LEDs intensity could
for example be lowered during night time, or they could be turn completely off. It is possible to
configure 24 different hours of the day, at where the LEDs intensity should be set.
Start Time The time at which the LEDs intensity shall be set to the corresponding intensity.
End Time The time at which the LEDs intensity shall be set to a new intensity. If no intensity is specified for
the next hour, the intensity is set to default intensity.
Intensity The LEDs intensity (100% = Full power, 0% = LED off).
Maintenance On time at link change
When a network administrator does maintenance of the switch (e.g. adding or moving users) he
might want to have full LED intensity during the maintenance period . Therefore it is possible to
specify that the LEDs shall use full intensity a specific period of time. Maintenance Time is the
number of seconds that the LEDs will have full intensity after either a port has changed link state,
or the LED pushbutton has been pushed. Valid range is from 0 to 65535 seconds.
On at errors
In the case where maximum power saving is enabled by turning the LEDs completely off, it might
be convenient to indicate to the network administrator that an error has been recorded in the
system log. By checking the "On at errors" the LEDs will be turned on at 100% in the case that
errors are logged in the system log.

Port Power Savings
This page allows the user to configure the port power saving features.
Object Description
Port Power Savings Configuration
Optimize EEE for The switch can be set to optimize EEE for either best power saving or least traffic latency.
Port Configuration
Port The switch port number of the logical port.
ActiPHY Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is power up for
short moment in order to determine if cable is inserted.
PerfectReach Cable length power savings enabled.
PerfectReach works by determining the cable length and lowering the power for ports with
short cables.
EEE Controls whether EEE is enabled for this switch port. For maximizing power savings, the circuit
isn’t started at once transmit data is ready for a port, but is instead queued until a burst of data
is ready to be transmitted. This will give some traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the frames to a
specific queue (done with QOS), and then mark the queue as an urgent queue. When an urgent
queue gets data to be transmitted, the circuits will be powered up at once and the latency will
be reduced to the wakeup time.
EEE Urgent Queues Queues set will activate transmission of frames as soon as data is available.
Otherwise the queue will postpone transmission until a burst of frames can be transmitted.

Thermal Protection
This page allows the user to inspect and configure the current setting for controlling thermal
protection. Thermal protection is used to protect the chip from getting overheated.
When the temperature exceeds the configured thermal protection temperature, ports will be
turned off in order to decrease the power consumption. It is possible to arrange the ports with
different groups. Each group can be given a temperature at which the corresponding ports shall
be turned off.
Object Description
Temperature The temperature at which the ports with the corresponding group will be turned off.
Temperatures between 0 and 255 C are supported.
Group The group the port belongs to. 4 groups are supported.

Selects any available link speed for the given switch port. Only speeds supported by the
specific ports are shown. Possible speeds are:
Disabled - Disables the switch port operation.
Auto - Port auto negotiating speed with the link partner and selects the highest speed that is
compatible with the link partner.
10Mbps HDX - Forces the cu port in 10Mbps half duplex mode.
10Mbps FDX - Forces the cu port in 10Mbps full duplex mode.
100Mbps HDX - Forces the cu port in 100Mbps half duplex mode.
100Mbps FDX - Forces the cu port in 100Mbps full duplex mode.

When a fixed-speed setting is selected, that is what is used. The Current Rx column indicates
whether pause frames on the port are obeyed, and the Current Tx column indicates whether
pause frames on the port are transmitted. The Rx and Tx settings are determined by the result
of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the setting for
Configured Link Speed.
Configure port transmit collision behavior.
Discard: Discard frame after 16 collisions (default).
Restart: Restart back off algorithm after 16 collisions.

Object Description
Frame Check Length Configures whether frames with incorrect frame length in the EtherType/Length field shall
be dropped. An Ethernet frame contains a field EtherType which can be used to indicate the
frame payload size (in bytes) for values of 1535 and below. If the EtherType/Length field is
above 1535, it indicates that the field is used as an EtherType (indicating which protocol is
encapsulated in the payload of the frame). If "frame length check" is enabled, frames with
payload size less than 1536 bytes are dropped, if the EtherType/Length field doesn't match
the actually payload length. If "frame length check" is disabled, frames are not dropped due
to frame length mismatch.
Note: No drop counters count frames dropped due to frame length mismatch.

DHCP Server
Mode
This page configures global mode and VLAN mode to enable/disable DHCP server per system
and per VLAN.
Object Description
Global Mode
Mode Configure the operation mode per system. Possible modes are:
Enabled: Enable DHCP server per system.
Disabled: Disable DHCP server per system.
VLAN Mode
VLAN Range Indicate the VLAN range in which DHCP server is enabled or disabled. The first VLAN ID must be
smaller than or equal to the second VLAN ID. BUT, if the VLAN range contains only 1 VLAN ID, then
you can just input it into either one of the first and second VLAN ID or both.
On the other hand, if you want to disable existed VLAN range, then you can follow the steps.
1. press “Add VLAN Range” to add a new VLAN range.
2. input the VLAN range that you want to disable.
3. choose Mode to be Disabled.
4. press “Save” to apply the change.
Then, you will see the disabled VLAN range is removed from the DHCP Server mode configuration
page.
Mode Indicate the operation mode per VLAN. Possible modes are:
Enabled: Enable DHCP server per VLAN.
Disabled: Disable DHCP server pre VLAN.
