Compact rail-mountable PoE+ media converter, matte black metal casing, two RJ-45 ports and one SFP slot, AC adapter included

Black Box Corporation

Black Box Corporation LGC5210A 2-port PoE+ network switch

SKU CH-7DKE-7JNF0 MPN LGC5210A

Gigabit media converter with two PoE+ RJ-45 ports and one SFP slot for fibre uplinks

  • Two PoE+ ports power and connect devices directly
  • Gigabit Ethernet delivers 1000 Mbps wired throughput
  • Single SFP slot adds fibre uplink flexibility
  • Compact rail-mountable design fits tight enclosures
  • RoHS and WEEE certified for eco-compliance

2-Port Gigabit PoE+ Media Converter

The Black Box LGC5210A converts 10/100/1000BASE-T signals to SFP fibre links while delivering PoE+ power on both RJ-45 ports. Rail-mountable and wall-mountable, it suits integrators extending powered devices such as cameras or access points beyond copper distance limits.

SFP Uplink and Copper Distance Constraints

The single SFP slot accepts standard Gigabit transceivers for fibre reach, while the twisted-pair side remains bound to the 100-metre Ethernet segment limit. Power is sourced from the included AC adapter, so the unit needs a nearby mains outlet; there is no management port for remote configuration.

Replaces Separate Converter and Injector Pairs

Installations that previously used a standalone media converter plus a mid-span PoE injector can consolidate to this single device. The jump is worthwhile when reducing rack space, cabling complexity and point-of-failure count outweighs the need for managed switching features.

Questions about this item

Should I choose the version with two PoE+ RJ-45 ports and one SFP slot for my fibre link?

Yes — the LGC5210A provides exactly two PoE+ RJ-45 ports plus a single SFP expansion slot, so one unit handles both copper endpoints and the fibre uplink.

What does the 10/100/1000Base-TX rating deliver once the switch is installed?

It gives full gigabit throughput on each copper port, auto-negotiating down to 10 or 100 Mbps for legacy devices while still powering them over PoE+.

How does the SFP interface limit the fibre connection in practice?

The single SFP slot accepts any standard 1000Base-X transceiver, so distance and fibre type are set by the module you install rather than the switch itself.
