Black Box LGC340A-R2 Managed Industrial Media Converter, 2 Gb RJ45 & 2 SFP Ports

Black Box LGC340A-R2 Industrial Media Converter, 2 Gb RJ45, 2 SFP Ports, Hardened Temperature

The LGC340A-R2 Media Converter Network Interface Device, (2) 10-/100-/1000-Mbps Copper to (2) SFP is a carrier-class DIN-rail switch that has the versatility to handle many applications at the edge of your network. Two autosensing 10-/100/1000-Mbps ports plus two autosensing 100-/1000-Mbps SFP slots in an intelligent switch enable you to use the Media Converter Network Interface Device for managed fiber termination, fiber drop and insert, fiber repeater, fiber mode conversion, and dual independent copper-to-fiber media conversion with automatic failover.

You can use the LGC340A-R2 as a copper/fiber or all copper switch. The versatility is in the SFP slots. As a copper/fiber switch, you can have two 10-/100-/1000-Mbps copper ports and two autosensing 100-/1000-Mbps fiber SFP ports. But the SFPs also support 10-/100-10000-Mbps copper operation. So if you insert two copper SFPs, you will have an entirely copper switch.

For more application diversity, the LGC340A-R2 gives you media conversion flexibility for distance extension. You can install it as a dual copper/fiber media converter then use it as two independent converters, saving a bundle in equipment costs. You can deploy this device as a 4-port device with fiber redundancy. And it gives you two different mode conversions to choose from 1+1 Non-Revertive and 1+1 Revertive. Both relate to how the box responds if a primary link fails. In Non-Revertive mode, the box will continue to use the backup fiber link after the failure on the primary link has been fixed. In Revertive mode, the box will revert to the primary link. The SFP slots auto-detect 100- or 1000-Mbps SFPs and comply with SFP Multi-Source Agreements standards (MSA) for complete compatibility with all standard SFPs.

It's designed for industrial use, featuring an extended temperature range of -40 to +185° F (-40 to +85° C) plus dual DC power (-48 VDC or 5-24 VDC).

The switch is fully manageable via CLI or SNMP. The switch has a mini-serial (RS-232) console management port that is accessed via the included mini-jack to DB9F cable.
