With two SFP fibre optic slots, the EX41922 can be used in a daisy chain formation, and is compatible with Etherwan’s Alpha-chain redundancy protocol, providing network redundancy with minimum failover time in both indoor and outdoor environments. The dual-rate compliant SFP interfaces allow for the continued use of existing equipment when migrating to a Gigabit network, achieving full forward and backward compatibility of network systems at a low cost.

The EX41922 switches are designed to operate even in the harshest environments, and can withstand temperatures from -40°C to 75°C (-40 to 167°F). Although unmanaged, the EX41922 is feature-rich with 10K jumbo frame support, full wire speed gigabit throughput, QoS support, and eco-friendly IEEE802.3az EEE (Energy Efficient Ethernet) compliance.
