3.3 Wiring
WARNING:
Do not disconnect modules or wires unless power has been switched off or the area is known to be non-hazardous. The devices may only be connected to the supply voltage shown on the type plate.
ATTENTION:
- Be sure to disconnect the power cord before installing and/or wiring your switches.
- Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size.
- If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.
- Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
- Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
-
You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring sharing similar electrical characteristics can be bundled together.
-
Separate input wiring from output wiring.
-
Label the wiring to all devices in the system.
3.3.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screws to the grounding surface prior to connecting devices.
3.3.2 Fault Relay
The relay contact of the 2-pin terminal block connector is used to detect user-configured events. The two wires attached to the fault contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the fault circuit remains closed.
3.3.3 Redundant Power Inputs
The LE2700 Series Industrial Managed Ethernet Switches switches support dual redundant power supplies, Power Supply 1 (PWR1) and Power Supply 2 (PWR2). The connections for PWR1, PWR2 and the RELAY are located on the terminal block.
Step 1: Insert the negative/positive DC wires into the V-/V+ terminals, respectively.
Step 2: To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connector.
Step 3: Insert the plastic terminal block connector prongs into the terminal block receptor.

3.4.3 B-Ring/B-Chain
B-Ring
You can connect three or more switches to form a ring topology to gain network redundancy capabilities through the following steps.
- Connect each switch to form a daisychain using an Ethernet cable.
- Set one of the connected switches to be the master and make sure the port setting of each connected switch on the management page corresponds to the physical ports connected. For information about the port setting, please refer to Section 4.1.2, Configuration.
- Connect the last switch to the first switch to form a ring topology.

B-RingFigure 3-10. B-Ring.
Coupling Ring
If you already have two B-Ring topologies and would like to connect the rings, you can form them into a coupling ring. All you need to do is select two switches from each ring to be connected, for example, switch A and B from Ring 1 and switch C and D from ring 2. Decide which port on each switch to be used as the coupling port and then link them together, for example, port 1 of switch A to port 2 of switch C and port 1 of switch B to port 2 of switch D. Then, enable Coupling Ring option by checking the checkbox on the management page and select the coupling ring in correspondence to the connected port. For more information on port setting, refer to Section 4.1.2, Configuration. Once the setting is completed, one of the connections will act as the main path while the other will act as the backup path.

Dual Homing
If you want to connect your ring topology to a RSTP network environment, you can use dual homing. Choose two switches (Switch A & B) from the ring for connecting to the switches in the RSTP network (Ciscos switches). The connection of one of the switches (Switch A or B) will act as the primary path, while the other will act as the backup path that is activated when the primary path connection fails.

B-Chain
When connecting multiple B-Rings to meet your expansion demand, you can create an B-Chain topology through the following steps.
- Select two switches from the chain (Switch A & B) that you want to connect to the B-Ring and connect them to the switches in the ring (Switch C & D).
-
In correspondence to the port connected to the ring, configure an edge port for both of the connected switches in the chain by checking the box in the management page (see Section 4.1.2, Configuration).
-
Once the setting is completed, one of the connections will act as the main path, and the other as the backup path.

4. Redundancy
Redundancy for minimized system downtime is one of the most important concerns for industrial networking devices. Hence, B-Ring has developed proprietary redundancy technologies including B-Ring, O-RSTP, and Open-Ring featuring faster recovery time than existing redundancy technologies widely used in commercial applications, such as STP, RSTP, and MSTP. B-Ring's proprietary redundancy technologies not only support different networking topologies, but also assure the reliability of the network.
4.1 B-Ring
4.1.1 Introduction
B-Ring is a proprietary redundant ring technology, with recovery time of less than 10 milliseconds and up to 250 nodes. The ring protocols identify one switch as the master of the network, and then automatically block packets from traveling through any of the network's redundant loops. If one branch of the ring gets disconnected from the rest of the network, the protocol automatically readjusts the ring so that the part of the network that was disconnected can reestablish contact with the rest of the network. The B-Ring redundant ring technology can protect mission-critical applications from network interruptions or temporary malfunction with its fast recover technology.
4.1.2 Configurations
B-Ring supports three ring topologies: Ring Master, Coupling Ring, and Dual Homing. You can configure the settings in the interface below.
| Table 4-1. Configuration screen components. | |
| Label Description | |
| Redundant Ring Check to enable B-Ring topology. | |
| Ring Master | Only one ring master is allowed in a ring. However, if more than one switch are set to enable Ring Master, the switch with the lowest MAC address will be the active ring master and the others will be backup masters. |
| 1st Ring Port The primary port when the switch is ring master. | |
| 2nd Ring Port The backup port when the switch is ring master. | |
| Coupling Ring Check to enable Coupling Ring. Coupling Ring can divide a big ring into two smaller rings to avoid network topology changes affecting all switches. It is a good method for connecting two rings. | |
| Coupling Port | Ports for connecting multiple rings. A coupling ring needs four switches to build an active and a backup link.Links formed by the coupling ports will run in active/backup mode. |
| Dual Homing Check to enable Dual Homing. When Dual Homing is enabled, the ring will be connected to normal switches through two RSTP links (ex: backbone Switch). The two links work in active/backup mode, and connect each ring to the normal switches in RSTP mode. | |
| Apply Click to apply the configurations. | |
NOTE: Do not set one switch as ring master and coupling ring at the same time, because this could cause heavy loading.
4.2 B-Chain
4.2.1 Introduction
B-Chain is Black Box's revolutionary network redundancy technology which enhances network redundancy for any backbone networks, providing ease-of-use and maximum fault-recovery swiftness, flexibility, compatibility, and cost-effectiveness in a set of network redundancy topologies. The self-healing Ethernet technology designed for distributed and complex industrial networks enables the network to recover in less than 10 ms for up to 250 switches if at any time a segment of the chain fails.
B-Chain allows multiple redundant rings of different redundancy protocols to join and function together as a large and the most robust network topologies. It can create multiple redundant networks beyond the limitations of current redundant ring technologies.
4.2.2 Configurations
B-Chain is very easy to configure and manage. Only one edge port of the edge switch needs to be defined. Other switches beside them just need to have B-Chain enabled.
| Table 4-2. B-Chain screen options. | |
| Label Description | |
| Enable Check to enable B-Chain function | |
| 1st Ring Port The first port connecting to the ring. | |
| 2nd Ring Port The second port connecting to the ring. | |
| Edge Port A B-Chain topology must begin with edge ports. The ports with a smaller switch MAC address will serve as the backup link and RM LED will light up. | |
4.3 MRP
4.3.1 Introduction
MRP (Media Redundancy Protocol) is an industry standard for high-availability Ethernet networks. MRP allowing Ethernet switches in ring configuration to recover from failure rapidly to ensure seamless data transmission. A MRP ring (IEC 62439) can support up to 50 devices and will enable a back-up link in 80ms (adjustable to max. 200ms/500ms).

4.4 STP/RSTP/MSTP
4.4.1 STP/RSTP
STP (Spanning Tree Protocol), and its advanced versions RSTP (Rapid Spanning Tree Protocol) and MSTP (Multiple Spanning Tree Protocol), are designed to prevent network loops and provide network redundancy. Network loops occur frequently in large networks as when two or more paths run to the same destination, broadcast packets may get in to an infinite loop and hence causing congestion in the network. STP can identify the best path to the destination, and block all other paths. The blocked links will stay connected but inactive. When the best path fails, the blocked links will be activated. Compared to STP which recovers a link in 30 to 50 seconds, RSTP can shorten the time to 5 to 6 seconds.

4.4.2 MSTP
Since the recovery time of STP and RSTP takes seconds, which are unacceptable in some industrial applications, MSTP was developed. The technology supports multiple spanning trees within a network by grouping and mapping multiple VLANs into different spanning-tree instances, known as MSTIs, to form individual MST regions. Each switch is assigned to an MST region. Hence, each MST region consists of one or more MSTP switches with the same VLANs, at least one MST instance, and the same MST region name. Therefore, switches can use different paths in the network to effectively balance loads.
Port Settings
This page allows you to examine and change the configurations of current MSTI ports. A MSTI port is a virtual port, which is instantiated separately for each active CIST (physical) port for each MSTI instance configured and applicable for the port. The MSTI instance must be selected before MSTI port configuration options are displayed.
This page contains MSTI port settings for physical and aggregated ports. The aggregation settings are stack global.

4.4.3 CIST
With the ability to cross regional boundaries, CIST is used by MSTP to communicate with other MSTP regions and with any RSTP and STP single-instance spanning trees in the network. Any boundary port, that is, if it is connected to another region, will automatically belongs solely to CIST, even if it is assigned to an MSTI. All VLANs that are not members of particular MSTIs are members of the CIST.

Such a port will be selected as an alternate port after the root port has been selected. If set, spanning trees will lose connectivity. It can be set by a network administrator to prevent bridges outside a core region of the network from influencing the active spanning tree topology because those bridges are not under the full control of the administrator. This feature is also known as Root Guard. |

5. Management
The switch can be controlled via a built-in Web server that supports Internet Explorer (Internet Explorer 5.0 or above versions) and other Web browsers such as Chrome. Therefore, you can manage and configure the switch easily and remotely. You can also upgrade firmware via a Web browser. The Web management function not only reduces network bandwidth consumption, but also enhances access speed and provides a user-friendly viewing screen.
NOTE: By default, IE5.0 or later version do not allow Java applets to open sockets. You need to modify the browser setting separately in order to enable Java applets for network ports.

| Label Description | |
| Relay Mode | Indicates the existing DHCP relay mode. The modes include:Enabled: activate DHCP relay. When DHCP relay is enabled, the agent forwards and transfers DHCP messages between the clients and the server when they are not in the same subnet domain to prevent the DHCP broadcast message from flooding for security considerations.Disabled: disable DHCP relay |
| Relay Server | Indicates the DHCP relay server IP address. A DHCP relay agent is used to forward and transfer DHCP messages between the clients and the server when they are not in the same subnet domain. |
| Relay Information Mode | Indicates the existing DHCP relay information mode. The format of DHCP option 82 circuit ID format is "[vlan_id][module_id][port_no}". The first four characters represent the VLAN ID, and the fifth and sixth characters are the module ID. In stand-alone devices, the module ID always equals to 0; in stacked devices, it means switch ID. The last two characters are the port number. For example, "00030108" means the DHCP message received form VLAN ID 3, switch ID 1, and port No. 8. The option 82 remote ID value equals to the switch MAC address.The modes include: Enabled: activate DHCP relay information. When DHCP relay information is enabled, the agent inserts specific information (option 82) into a DHCP message when forwarding to a DHCP server and removes it from a DHCP message when transferring to a DHCP client. It only works when DHCP relay mode is enabled.Disabled: disable DHCP relay information |

| Label Description | |
| Relay Information Policy | Indicates the policies to be enforced when receiving DHCP relay information. When DHCP relay information mode is enabled, if the agent receives a DHCP message that already contains relay agent information, it will enforce the policy. The Replace option is invalid when relay information mode is disabled. The policies includes:Replace: replace the original relay information when a DHCP message containing the information is received.Keep: keep the original relay information when a DHCP message containing the information is received.Drop: drop the package when a DHCP message containing the information is received. |
