Black Box LE2721C Hardened Managed Modular Switch Module 8 Port

Condition: New

Black Box LE2721C Hardened Managed Modular Switch Module 8 Port Hardened Managed Modular Switch Module - 8-Port, 100/1000-Mbps, SFP.

Add eight 100-/1000-Mbps SFP ports to the LE2700 Series Hardened Managed Switch Chassis.

Scalable, flexible, cost-effective modular design enables you to add capacity as demand increases.
Customizable. Choose the right quantity, speed, and interfaces for your application.
Dual power supplies provide network redundancy with <30 millisecond failovers.
Designed for extreme temperatures of -40 to +185° F (-40 to +85°C).
Configure and monitor installations remotely. No truck rolls needed.
Supports Web, SNMP, and console user interfaces.
Accommodates high-availability protocols, including xSTP, link aggregation, and redundant ring.
Manages traffic with 802.1p/q tagged frames. Handles jumbo frames.
Supports IP multicast snooping with IGMPv2/v3.
IEEE 802.3az energy efficient.

Use the SFP+ transceivers (LFP400 Series) with this 100-/1000-Mbps module to add the connectors of your choice.
By plugging in different SFPs, you can customize the LE2700 Series switch to the distances and connectors you need.
Designed for applications such as: oil/gas wells, electric substations, railways, utilities, and other industrial environments.
Works in slots one, two, and three of the LE2700 Series Hardened Managed Modular Switch Chassis (LE2700A, LE2700UK, or LE2700AE).
