FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What should be backed up before replacing Allen-Bradley 1783-BMS20CL?
Export or record the complete switch configuration, including the management IP address, VLANs, Smartport roles, DLR settings, port security, and alarm configuration before removing the installed switch.
Are SFP transceivers and network cables included with Allen-Bradley 1783-BMS20CL?
No. Select supported SFP transceivers, fiber patch leads, and copper cables separately for the installed port and media requirements.
Can Allen-Bradley 1783-BMS20CL use redundant DC power inputs?
Yes. The switch provides two DC power-input connections that can be wired to separate Class 2 or SELV sources; confirm polarity, source ratings, grounding, and the alarm configuration.
What must be checked when selecting fiber media for Allen-Bradley 1783-BMS20CL?
Match the supported SFP catalog number, fiber type, wavelength, connector type, link distance, and the SFP used at the opposite end of the link.
What should be verified before commissioning a DLR ring on Allen-Bradley 1783-BMS20CL?
Verify the selected ring ports, supervisor or ring-node role, beacon settings, IP configuration, firmware compatibility, and the configuration of every device in the ring.
How can the alarm connection on Allen-Bradley 1783-BMS20CL be used?
The alarm relay can report configured switch conditions to external monitoring equipment. Confirm the selected alarm triggers and wire the relay within the published contact ratings.
Is 1783-CMS20DB a direct drop-in replacement for Allen-Bradley 1783-BMS20CL?
Treat 1783-CMS20DB as an engineering replacement, not an automatic drop-in substitution. Compare port media, mounting, power, firmware, licensed features, DLR behavior, and the saved switch configuration before migration.
