Product Description
The Allen-Bradley 1783-BMS20CL Stratix 5700 is a 20-port managed Ethernet switch designed for high-performance industrial networks. It features 16 RJ45 Fast Ethernet ports, 2 Fast Ethernet combo ports, and 2 Fast Ethernet fiber ports. Supporting topologies like Device Level Ring (DLR) for network redundancy, it can act as a supervisor node, gathering ring information, managing DLR status, providing diagnostics, and rerouting traffic in case of a ring break. It supports CIP over Ethernet for communication with Logix controllers and visualization systems. The switch operates on 12-48V DC (0.5-3.0A) using a SELV or Class 2 power supply, with a typical power consumption of 21W at 40C and 24V DC, and a peak of 30W. It's type-tested at 850V DC for 60 seconds isolation voltage, comes in an open enclosure with a T4 IEC temperature code, weighs 2.04 kg, measures 5.1 x 5 x 5.3 inches, and operates between -40 and 60C. It supports Linear, Star, and DLR topologies and does not require a backplane, needing external power and installation within a protective enclosure.
Is Your Device Showing These Signs?
The Allen Bradley 1783-BMS20CL managed switch commonly experiences issues such as backplane failures, resulting in complete communication loss and requiring backplane replacement. Configuration corruption is a frequent problem, necessitating a firmware reset and configuration reload. Power supply failures are observed, indicated by a lack of LED activity and requiring power supply replacement. Port failures occur due to electrostatic discharge (ESD) or physical damage, demanding port disabling or switch replacement. Excessive network traffic and broadcast storms overwhelm the switch, resolved through VLAN configuration and traffic shaping.

Our Repair Process for the
1783-BMS20CL
Our repair process for the Allen Bradley 1783-BMS20CL managed switch begins with a comprehensive diagnostic evaluation to pinpoint the failure. Backplane failures, indicated by communication loss, require immediate backplane replacement. Configuration corruption necessitates a complete firmware reset and configuration reload to factory defaults, followed by a precise configuration reload. Power supply failures, identified by the absence of LED activity, demand a direct power supply replacement. Port failures resulting from ESD or physical damage result in port disabling or complete switch replacement, depending on the severity. Excessive network traffic and broadcast storms are resolved through meticulous VLAN configuration and traffic shaping implementation.
