This manual serves the following ComNet Model Numbers:
CNGE2+2SMS
CNGE2+2SMSPOE
CNGE2+2SMSPOEHO
The ComNet CNGE2+2SMS[POE][HO] is a four port intelligent switch with light management functionality. It provides two 10/100/1000Base-T(X) copper ports and two 100/1000Base-FX SFP ports. The CNGE2+2SMS[POE][HO] provides exclusive functionality for easy field deployment including DIP switch based operation of RSTP for creating redundant network topologies as well as preventing network video flooding of multicast traffic with IGMP snooping. Ports 1 and 2 can optionally supply up to thirty (30) watts of power per port based on the IEEE 802.3at standard. An optional High Output (HO) version is also available that can supply up to sixty (60) watts of PoE from ports 1 and 2. This product is fully compatible with the ComNet exclusive CopperLine® SFP modules for operation over extended distance UTP or Coax cable. The ComNet exclusive Port Guardian feature provides additional cyber security protection by enabling physical port lockout in the event that an existing cable is disconnected and prevents a potential network incursion using common spoofing techniques. The intrusion event is reported back to the operator using SNMP.

Below
Attention: ComNet recommends maximum number of units per ring is limited to 20 devices.
Numbers higher than this may cause undesired performance and are not supported by ComNet.
Note: The unit at the control room location should have DIP switch 3 ON (ROOT BR). This will
force the ring to break at the half way point and ensure most effective load sharing on the network.

Numbers higher than this may cause undesired performance and are not supported by ComNet.
Attention: Central switch must be manually configured to be the root bridge. This requirement is
mandatory for correct performance in a multiple ring scenario.
Attention: ComNet recommends maximum number of rings per core switch is limited to 3-4.
The actual number supported will depend on the processing power of the core switch used and other features that may be enabled on the core switch. Please contact ComNet Technical Support to discuss your application prior to ordering.

Upgrade Firmware allows you to update the firmware of the switch. Before updating, have your Windows firmware update application ready and the firmware image is available. RSTP is not available during the firmware update process so please, observe the network topology before upgrading.
Update Firmware interface
Details on how to upload the new image is located in Firmware Upgrade section on Page 51.
After applying a new firmware version, it is recommended that a Factory Default Reset is performed to ensure that all new or adjusted settings take effect. Please note that performing a Factory Default reset will erase all the devices settings except for the IP address.
Warning Do not enable the firmware update process unless you have a firmware file available
and are ready to upgrade the unit. Once this processed is started it cannot be cancelled and if a new firmware is not uploaded to the unit it will be necessary to return the unit to the factory for re-programming.

SNMP
Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes (servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. Network management systems learn of problems by receiving traps or change notices from network devices implementing SNMP.

Port Guardian
The Port Guardian feature provides a high security managed port lock out mode and when enabled will power down the port as soon as a link loss status is detected when a cable is disconnected. This provides high security against network attack by an intruder who accesses the edge device and disconnects it to then try and connect their own intrusion device (laptop, network sniffer etc.).
To reset a port from a lock out state the network administrator can issue an SNMP reset or can reset a port by using the CLI via the USB serial port. In PoE models a reset can also be initiated by using one of the contact inputs.
Label Description
