Black Box Corporation

Black Box Corporation LE2721C 8-port Gigabit hardened switch module

SKU CH-Q1X9-BERTP MPN LE2721C

Eight-port Gigabit Ethernet module with SFP slots for hardened temperature environments and Black Box LE2700 series compatibility

  • Gigabit Ethernet for high-speed data networking
  • Eight SFP expansion slots for flexible fibre connectivity
  • Hardened temperature design for demanding industrial environments
  • TAA compliant for government procurement requirements
  • WEEE certified and environmentally friendly construction

Hardened Gigabit Switch Module

The Black Box LE2721C is an eight-port Gigabit Ethernet switch module built for hardened temperature environments. It accepts eight SFP mini-GBIC transceivers to deliver 100/1000 Mbps fibre or copper connectivity. The module is designed specifically for integration with Blackbox LE2700 series switches. It suits network engineers deploying reliable data links in industrial or outdoor cabinets.

Installation and Compatibility

The unit slides into a compatible LE2700 chassis and connects via standard SFP slots, so no specialised tools are required beyond the transceivers themselves. Installers must verify that the host switch is an LE2700 model; other chassis will not accept the module. Transceiver choice determines reach and fibre type, so mismatched SFPs are the most common cause of link failures. The module carries WEEE certification and is TAA compliant for regulated projects.

Sustained Load Behaviour

Under continuous traffic the hardened design maintains Gigabit throughput across all eight ports without thermal throttling in the rated temperature range. The fanless construction eliminates moving-part wear during long-term operation. Performance stays consistent for extended data transfers typical of surveillance or SCADA networks. The five-year limited warranty reflects the manufacturer's confidence in sustained reliability.

Questions about this item

How do I verify the LE2721C module is operating correctly after installing it in a Blackbox LE2700 Series switch?

Confirm all eight SFP slots show link LEDs at 100 or 1000 Mbps and that the module reports a healthy status in the switch management interface.

What ships with the LE2721C hardened switch module and what must I purchase separately?

The module itself is supplied; SFP transceivers for the eight mini-GBIC slots are not included and must be bought separately.

Which capacity or version of the LE2721C should I choose for my network?

The LE2721C provides eight Gigabit SFP ports in a single hardened module; select it when you need exactly eight 100/1000-Mbps uplinks for a compatible LE2700 chassis.
