fixed ST or SC optics
› Environmentally hardened for deployment in difficult unconditioned
out-of-plant installations: Extended ambient operating temperature
range of -40˚ C to +85˚ C, for use in virtually any environment.
Conformal coating is optionally available for humidity with
condensation or airborne particulate matter environments.
› Dual-redundant power supplies significantly reduce the possibility
of a single-point-of-failure, for the highest system and network
reliability. Multiple AC and DC operating voltages with front or rear
chassis power connection interfaces 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
› Layer 3 static routing, and RIP functions
› C-Ring compatible: Network recovery time <30ms, with >250
switches within the ring, for Ethernet redundancy.
› Supports Loop Protection function
› MSTP, with RSTP/STP compatibility
› Ethernet Ring Protection Switching (ERPS) (G.8032)
› IPV6 internet protocol (latest version)
› Support for Modbus TCP protocol
› 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-Compliant
› SMTP client, & 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
› ACL, TACACS+ and 802.1x User Authentication for network security
› 10K Bytes Jumbo Frame
› Web-based, Telnet, Console (CLI), and Windows utility (eConsole)
configuration
› Rugged 19-inch rack-mount steel housing, 1 RU high (1.75”)
(Can be mounted in front or rear facing orientation)
› No fans or forced-air cooling; cooling via natural convection
eliminates unreliable and troublesome fans/moving parts, with no
periodic maintenance requirements
› Lifetime Warranty
ComNet product series RLXE4GE24MODMS is a substation-rated and industrially-hardened
modular-configuration all-gigabit managed layer 2 switch/layer 3 router. The RLXE4GE24MODMS
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 layer 3 static routing functionality allows
for the participation and foundation of a core network infrastructure.
The user-configurable modularity provides a truly future-proof platform that may be upgraded
or changed in the field at any time, to support changes in the user’s communications and
networking requirements as they arise. Four slots are provided in the chassis for accommodating
individual modules featuring different combinations of SFP* and electrical 10/100/1000BASE-
TX communications ports. The uplink module slot can accept either a 1 gigabit or a 10 gigabit
module, with two or four 1 or 10 Gbps SFP+ ports. Dual user-replaceable redundant power supply
modules provide an extremely high level of switch/router reliability, for those applications where the
possibility of a power supply single-point-of-failure cannot be tolerated.
When configured with the 8-port 100/1000BASE-X SFP or 4 100 or 1000BASE-FX fixed ST or SC
optics communications modules, the RLXE4GE24MODMS may be used for network aggregation
applications, or where it is desirable to provide optical connectivity directly to the switch/router in
electrically-noisy environments.
The RLXE4GE24MODMS 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.
