CNGE24FX12TX12MS[POE]

Industrial Grade Managed Ethernet Switch w/

12 × 100/1000Base-FX + 12 × 10/100/1000Base-TX Ports w/ Optional 30W PoE

The ComNet CNGE24FX12TX12MS[POE] has twelve 100/1000Base-FX SFP* ports and twelve 10/100/1000Base-TX ports. 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. Application-based QoS can set a higher priority for data streaming. The Device-Binding function can prevent unauthorized network access, increasing security.

The CNGE24FX12TX12MSPOE models provide twelve electrical ports supporting up to thirty watts of power. All PoE ports are IEEE 802.3at compliant.

Each model is provided with redundant power inputs which can be either one mains voltage and one or two low voltage DC inputs or two low voltage DC inputs.

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.

Ports

This page displays curent port configurations. Ports can also be configured here.

Object	Description
Port	This is the logical port number for this row.
Description	The description of the port. It is an ASCII string no longer than 256 characters.
Link	The current link state is displayed graphically. Green indicates the link is up and red that it is
	down.
Current Link Speed	Provides the current link speed of the port.
Configured Link	Selects any available link speed for the given switch port. Only speeds supported by the
Speed	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.
	1Gbps FDX - Forces the port in 1Gbps full duplex.
	2.5Gbps FDX - Forces the port in 2.5Gbps full duplex mode.
Advertise Duplex	When duplex is set as auto i.e auto negotiation, the port will only advertise the specified
	duplex as either Fdx or Hdx to the link partner. By default port will advertise all the supported
	duplexes if the Duplex is Auto.
Advertise Speed	When Speed is set as auto i.e auto negotiation, the port will only advertise the specified
	speeds (10M 100M 1G) to the link partner. By default port will advertise all the supported
	speeds if speed is set as Auto.
Flow Control	When Auto Speed is selected on a port, this section indicates the flow control capability that
	is advertised to the link partner.
	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.

Object	Description
Maximum Frame Size	Enter the maximum frame size allowed for the switch port, including FCS.
Excessive Collision	Configure port transmit collision behavior.
Mode	Discard: Discard frame after 16 collisions (default).
	Restart: Restart back off algorithm after 16 collisions.
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.
Apply	Click to apply changes.
Reset	Click to revert to previous values.

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.
Add VLAN	Click to apply to add a new VLAN range.
