Substation-Rated DIN-Rail Mountable All-Gigabit Managed Layer 2 Switch
with 16 10/100/1000 BASE-TX Ports + 4 Gigabit SFP* Uplink Combo Ports
RLGE20FX4TX16MS
ComNet product series RLGE20FX4TX16MS is a substation-rated and industrially-hardened
DIN-rail mount all-gigabit managed layer 2 switch. Fully compliant with the requirements of
IEC 61850-3, IEEE 1613 Class 2, EN50155, and NEMA TS-1/TS-2, the RLGE20FX4TX16MS
is intended for deployment in environments where high levels of electromagnetic noise and
interference (EMI) and severe voltage transients and surges are routinely encountered, such
as electrical utility substations and switchyards, heavy manufacturing facilities, track-side
electronic equipment, and other difficult out-of-plant installations.
The RLGE20FX4TX16MS provides 16 10/100/1000BASE-TX communications ports, with 4
10/100/1000BASE-TX or 100/1000BASE-FX SFP uplink ports. The use of SFPs for the four
(4) gigabit uplink ports provides a truly future-proof platform where the uplink optics may be
changed in the field at any time, to support changes in the user’s networking or cable plant
requirements as they arise.
The internal/self-contained 12 to 60 VDC or 85 to 264 VAC/88 to 373 VDC power supply
features redundant power inputs, for the highest possible reliability in those installations
where network availability is of the utmost importance.
The RLGE20FX4TX16MS supports multiple Ethernet redundancy protocols, including ComNet
C-Ring (recovery time < 30ms, with >250 switches integrated within the ring), and MSTP
with RSTP/STP compatibility. With its extremely fast recovery time, the most mission-critical
applications are fully protected from network interruptions or temporary malfunctions due to
possible short or long-term faults or outages within the network.
FEATURES

out-of-plant installations: Extended ambient operating temperature
range of -40˚ C to +75˚ C, (functional to +85 degrees C) for use in
virtually any environment. Conformal coating is optionally available
for humidity with condensation or airborne particulate matter
environments.

a single-point-of-failure, for the highest system and network reliability.
Multiple AC and DC operating voltages available
› Supports IEEE 1588v2 Precision Timing Protocol, Transparent Clock
Synchronization (TC), for protective relaying and control applications
› User-programmable alarm relay for local or remote indication of a fault
condition

› VLAN Unaware: Supports priority-tagged frames to be received by
specific IEDs (Intelligent Electronic Devices)
› Provides HTTPS/SSH protocol for enhanced network security
› IEEE 802.3az Energy-Efficient Ethernet technology, for substantially
reduced power consumption during periods of low data activity.
› SMTP client, NTP server protocol, and IP-based bandwidth
management
› Application-based QoS management
› Device Binding security function
› DOS/DDOS auto-prevention
› IGMP v2/v3 (IGMP snooping support) for filtering multicast traffic
› SNMP v1/v2c/v3 & RMON & 802.1Q VLAN Network Management
› Port mirror function to monitor port data
› ACL, TACACS+ and 802.1x User Authentication for network security
› 9.6K Bytes Jumbo Frame
› Multiple notifications for warning of unexpected events
› Web-based, Telnet, Console (CLI), and Windows utility (eConsole)
configuration
› Supports LLDP Protocol eConsole support
› Ingress Protection Rating: IP-30, with rugged and robust DIN-rail
mountable metal housing
› No fans or forced-air cooling; cooling via natural convection eliminates
unreliable and troublesome fans/moving parts, with no periodic
maintenance requirements
› Lifetime Warranty
* Small Form-Factor Pluggable Module. Sold separately.
