What this adapter does

The Black Box SW1041A is a latching Layer 1 A/B switch that connects two ports to a single common port. It suits network administrators who need to redirect a live Ethernet or serial link without interrupting the physical connection. Manual switching is available via the front-panel A/B push button, and remote control is possible through a dry-contact interface. The unit maintains the active path even when power is lost.

The spec that decides fit

This device provides one serial management port alongside its switched Ethernet paths. If your infrastructure requires an RS-232 console connection for out-of-band control, the built-in serial interface satisfies that requirement. Buyers who need multiple serial ports or a different management protocol will not find those options here.

Behaviour under sustained load

The latching relay design holds the selected path without continuous coil power, so the connection remains stable during extended operation or unexpected power interruptions. The metal enclosure measures 2.5 inches high, 6.3 inches wide and 8.1 inches deep, weighing approximately 4 lb. It complies with WEEE and RoHS environmental standards and is manufactured in the United States.

Questions about this item

What does the single RS-232 port do on this A/B switch?

It provides the remote-control interface so the switch can be toggled from another device without pressing the front button.

What does the latching design mean for the Ethernet path?

The connection stays physically latched even if power is lost, so the selected port remains linked.

How much rack depth does the unit need?

The chassis is 8.1 inches deep, so allow at least that much clear space behind the mounting ears.
