Managed ethernet Switch with (16) 10/100tX +
(2) configurable 10/100/1000tX / 100/1000fX PortS
v2.01 Jan 2012
The ComNet™ CNGE2FE16MS Managed Ethernet Switch provides robust transmission
of (16) 10/100 BASE-TX and (2) 10/100/1000TX or 100/1000FX combo ports, of gigabit
Ethernet data. Unlike most Ethernet switches, these environmentally hardened units
are designed for direct deployment in difficult out-of-plant or roadside operating
environments, and are available for use with either conventional CAT-5e copper or
optical transmission media. Diverse media selection allows for easy implementation
of point-to-point, linear add-drop, drop-and-repeat, star, or true self-healing ring and
mesh network system architectures. The 16 electrical ports support the 10/100 Mbps
Ethernet IEEE 802.3 protocol, and auto-negotiating and auto-MDI/ MDIX features are
provided for simplicity and ease of installation. 2 ports are 10/100/1000 configurable
for copper or fiber media for use with multimode or single mode optical fiber, selected
by optional SFP modules. These network managed layer 2 switches are optically
(100/1000 BASE-FX) and electrically compatible with any IEEE 802.3 compliant
Ethernet devices. Plug-and-play design ensures ease of installation, and no electrical
or optical adjustments are ever required. The CNGE2FE16MS incorporates LED
indicators for monitoring the operating status of the managed switch and network.
These units are DIN-rail or wall mountable.

  • Page 95 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS Legacy_Ring Mode Setting the X-Ring2 Operation Mode on Legacy-Ring mode means the switch is configured as a backward compatible device that could only be a non-master switch when joining a legacy X-Ring group. » 1st Ring Port: Use the pull-down menu to select a port as the first ring port.
  • Page 96 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS LLDP Configuration Link Layer Discovery Protocol (LLDP), a one-way protocol, specified in the IEEE 802.1ab standard allows stations attached to the same IEEE 802 LAN to advertise their information to neighbors and store the information received from adjacent stations.
  • Page 97 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS 802.1X/Radius 802.1x is an IEEE authentication specification that allows a client to connect to a wireless access point or wired switch but prevents the client from gaining access to the Internet until it provides authority, like a user name and password that are verified by a separate server.
  • Page 98 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS Port Configuration You can configure the 802.1x authentication state for each port. The state provides Disable, Accept, Reject, and Authorize. » Reject: The specified port is required to be held in the unauthorized state. » Accept: The specified port is required to be held in the authorized state.
  • Page 99 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS Misc Configuration » Quiet Period: Set the period that the port does not try to acquire a supplicant. » TX Period: Set the period the port waits for retransmitting the next EAPOL PDU during an authentication session.
  • Page 100 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS MAC Address Table Here users can determine whether the incoming traffic passes through the particular ports or is blocked in accordance with the MAC-address filtering table. Static MAC Address Configure the static MAC address tab to make a list in which traffic from devices with the MAC address included will pass the port.
  • Page 101 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS MAC Filtering The switch will block traffic from devices with the MAC address listed in this table. Figure 92 – MAC Filtering interface » MAC Address: Enter up to 256 MAC addresses. » Select the Add button.
  • Page 102 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS All MAC Addresses This tab displays dynamic and static MAC addresses on each port. » Port No: Use the pull-down menu to select a particular port to show its MAC address information. » Select the Clear MAC Table button to clear the listed entries of the current MAC address information.
  • Page 103 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS IGMP/MLD Snooping IGMP is the protocol used by IPv4 systems to report their IP multicast group memberships to neighboring multicast routers. To handle multicast management on IPv6 networks, Multicast Listener Discovery (MLD) is used in a similar way by IPv6 systems.
  • Page 104 INSTALLATION AND OPERATION MANUAL CNGE2FE16MS Static Filtering Multicasts are similar to broadcasts, they are sent to all end stations on a LAN or VLAN. Static filtering is the function for users to configure a list of multicast groups by specifying the multicast MAC address and member ports for each entry.

    INSTALLATION AND OPERATION MANUAL CNGE2FE16MS Troubleshooting » Verify that you are using the right power cord/adapter. Do not use a power adapter with DC output higher than the rated voltage of the switch. This will result in severe damage. » Select the proper network cable to construct your network. Please confirm that you are using the correct cable.
