Servicing Information

To Clear a “Lost” Password

1)Remove power from the bridge/router.

2)Remove the screw securing the LAN / Console module to the rear of the bridge/router. Be sure to grip the module only by the flange at the bottom of the metal panel.

3)Unplug the LAN / Console module approximately 1/2 inch from the bridge/router. Be sure to grip the module only by the flange at the bottom of the metal panel. The module only needs to be removed slightly to disconnect the module from the internal main board.

WARNING:

Because of the close proximity of the AC power from the power

coupler, do not insert anything into the LAN / Console opening while

the bridge/router is powered up.

4)Reattach the power to the bridge/router and wait for the power-up diagnostics to finish. The Power LED will turn green.

5)Remove power from the bridge/router.

6)Re-install the LAN / Console module and secure it with the screw.

7)Power up the bridge/router.

8)Log into the bridge/router using the default password “BRIDGE” and change the password as desired.

Changing LAN or WAN Interfaces

1)Remove power from the bridge/router.

2)Remove the screw securing the interface module to the rear of the bridge/router.

3)Remove the interface module from the bridge/router. Be sure to grip the module only by the flange at the bottom of the metal panel.

4)Install the new interface module and secure it with the screw.

5)Power up the bridge/router.

Important: there must be a module in slot 1 (left side module position when viewed from the rear of the unit) before a module in slot 2 (center position) will operate.

For this model, if a LAN 2 module is installed it must go in slot 1. Note in addition that installing a LAN 2 module will clear the IP address of LAN 1. After installing a LAN 2 module, the IP address for both LANs must be entered.

Selecting MDI or MDI-X LAN Interface

For most LANs, where a number of devices are connected via a hub, this router will be connected via the LAN cable to the MDI port. However, in locations where a single workstation is to be connector to the router, the cable from the workstation should be plugged into the MDI-X port. This eliminates the need for a hub at a remote site that has only one LAN device.

LR5200A-R2, LR5100A-T specifications

The Black Box LR5100A-T and LR5200A-R2 are advanced network media converters designed to facilitate seamless data transmission across various media types. These devices are particularly valuable for organizations seeking high-performance solutions for extending network communications beyond traditional limits.

The LR5100A-T is an Ethernet media converter that operates over twisted pair cabling, efficiently converting 10/100/1000 Mbps Ethernet signals into fiber optic signals. This capability allows businesses to harness the long-distance advantages of fiber optics while maintaining compatibility with existing Ethernet infrastructure. With a broad range of supported distances, users can effectively communicate over distances up to 100 kilometers, depending on the type of fiber optic cable used and the transmission rate.

In contrast, the LR5200A-R2 emphasizes compatibility with a wider range of fiber types and supports both multimode and single-mode fiber connections. It also provides auto-negotiation capabilities, which enable it to automatically detect and configure to the optimal speed of connected devices, streamlining setup and enhancing user experience.

One of the key features of both the LR5100A-T and LR5200A-R2 is their rugged design, making them suitable for deployment in harsh environments. They are engineered to withstand extreme temperatures and are resistant to vibration, ensuring reliability in challenging settings. Additionally, both models adhere to industry standards, ensuring interoperability with a diverse array of networking equipment.

Notably, these converters come equipped with LED indicators that allow for real-time monitoring of device status, simplifying network management and troubleshooting. This feature ensures that technicians are promptly alerted to any connectivity issues, significantly reducing downtime.

Powering options for both models include standard AC power supplies or Power over Ethernet (PoE), allowing for flexible deployment scenarios without the need for additional power outlets. This flexibility can be a crucial factor in environments where power availability may be limited.

With their blend of performance, durability, and advanced features, the Black Box LR5100A-T and LR5200A-R2 media converters represent a solid choice for organizations looking to future-proof their network infrastructure while ensuring high levels of connectivity and reliability. Whether extending existing networks or implementing new solutions, these devices provide the necessary tools for effective communication in today’s digital world.
