Electrical Substation-Rated

10/100/1000 Mbps 3-Port Self-managed Ethernet Switch

RLGE2+1SMS

The ComNet RLGE2+1SMS is a substation-rated and industrially hardened three-port self-managed switch with
uplink management functionality. Fully co mpliant wit h the requirement s of IEC 61850-3, IEEE 1613 Class 2, EN50155,
and NEMA TS-1/TS-2, it is designed 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, trackside and roadside electronic equipment, and
other difficult out-of-plant applications. The DIP-switch-selec table 100BASE-FX or 1000BASE- FX port suppor ts
conventional CAT-5e/CAT-6 copper or optical transmission media by selection of the appropriate ComNet SFP*
module. User-selectable link fault pass-through provides remote indication of a network fault, and two summary
fault alarms provide a local or remote indication via dry contact closures in the event of loss of optical link or
operat in g power. T he 10/10 0/100 0B ASE-T X ports support both auto-negotiation and automatic MDI/MDI-X
crossover for full and half-duplex operation; manual MDI/MDI-X switching is not required. The RLGE2+1SMS
comes pre-programmed, preventing network video flooding with DIP-switch selection of the SFP port as uplink or as
an unmanaged switch.

The internal/self-contained 12 to 24 VDC , 48 VDC, or HV AC/DC power supply features redundant power inputs
when used with 12 to 24 VDC or 48 VDC power sources, for the highest possible reliability. The simple to install,
plug-and-play RLGE2+1SMS is DIN-rail or panel-mountable, and is ideal for mission-critical applications where very
high levels of reliability and network availability are of the utmost importance.

FEATURES

› Full duplex transmission of 10/100/1000 Mbps Ethernet:

(2) 10/10 0/1000 BASE-TX por ts and
(1) 100BASE-FX or 1000BASE-FX SFP port

› Designed to the requirements of IEC 61850-3 and IEEE 1613

Class 2 for elec trical utility substations, EN50155 for railway
applications, and NEMA TS-1/TS-2 for traffic signal control
equipment, and IEC/EN60950-1

› Extended ambient operating temperature range of -40º to +85º C,

for use in virtually any environment. Optional conformal coating
available for humidity with condensation or airborne particulate
matter environments

› Uses customer-installed ComNet SFPs for compatibility with a

wide range of optical fibers, optical connec tor types, and optical
transmission distances of up to 120 km

› Link fault pass-through provides a remote indication of a network fault

› 10/100/1000BASE-TX ports support both auto-negotiation and

automatic MDI/MDI-X crossover for full and half-duplex operation;
manual MDI/MDI-X switching is not required

› 12 to 24 VDC, 48 VDC or HV AC/DC (88 to 300 VDC/85-264 VAC)

operating power options

› Internal/self-contained high-reliability power supply eliminates

the need for an external power supply, and a screw terminal block
connec ts directly to the power source for permanent, reliable, and
maintenance-free operation

› 12 to 24VDC and 48 VDC input power supply versions feature

redundant power inputs, for extremely high levels of reliability
and availability

› No fans or forced-air cooling required; cooling via natural

convection eliminates unreliable and troublesome fans/moving
parts for improved reliability

› Indicating LEDs confirm operating status of the switch and the link

for ease in troubleshooting

SUBSTATION DIN RAIL -40º TO +85ºEXCLUSIVE

› Summary fault alarm provides a local or remote indication via dry

contact closure in the event of loss of optical link or operating power

› Rugged 19-gauge galvanized & powder-coated steel enclosure

may be DIN-rail or panel-mounted

› Made in the USA

› Lifetime Warranty
