Product Description
"NL" Family Principle
MEN's "NL" Ethernet switch family principle is based on a wide range of configuration
options (e.g., amount of Ethernet ports, fiber connections or Power over Ethernet) to
easily adapt the switch to application requirements.
Flexible Concept in a Small Housing
The NL30 is a 12+2-port fully managed layer 2/3 Ethernet switch, providing a wide range
of configuration options with 12 M12 Gigabit Ethernet ports. M12 connectors can be
configured to be A-, D- or X-coded and combinations are also possible. The X-coded
connectors are designed as push-pull and screwed variants (Harting concept). The NL30
offers two optional Ethernet fiber ports with 1000BASE-SX as standard variant. The
mechanical concept is an extremely compact, high-quality aluminum housing providing
high port density and ultra-high ruggedness. It is designed for wall-mounting, but
mounting in a 19" rack is also an option. Product models without optional fiber ports are
available in a housing with reduced height.
Performance, Security and Diagnostic Features
The 29 Gbit/s, TCAM based, store-and-forward switching matrix of the NL30 allows high-
performance layer 2 switching over all connected interfaces. For easy remote
management and access, layer 3 protocols, e.g., IPv4/IPv6 and DHCP, are integrated. The
switch provides extended security features like SNMPv3, SSH and HTTPS. Traffic isolation
(VLAN) and switching redundancy protocols (e.g., STP, RSTP, MSTP) provide safe running
of the network using redundant data paths in the event of a fault. The ITU-T G.8031/
G.8032 ring and linear protection switching feature set makes NL30 able to create
network ring scenarios with recovery time under 50 ms. Monitoring and diagnosis
functions, e.g., sFlow or SNMPv1, v2c, v3 are provided.
Wide-Range Power Supply
The EN 50155 compliant supply voltage range of 24 V DC to 110 V DC provides maximum
flexibility for using the switch.
Maintenance Free and Extremely Rugged
The NL30 is designed for fanless operation at temperatures ranging from -40 °C to
+70 °C (10 min @ +85 °C). The cooling fins serve as a heat sink for the internal
electronics. It is maintenance-free and developed specifically for rough environmental
conditions in rolling stock applications. Long-term availability until 2026 from product
start minimizes lifecycle management by making the system available at least for this
period of time.
