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 10/100/1000BASETX 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 longterm faults or outages within the network.
