1.2. Ethernet Panel Description
Each Ethernet module is equipped with two LEDs that indicate link/activity status information. The LED
will be solid for ports with link, and will blink for activity. The diagram in Figure 1.1, “Ethernet panel LED
description” highlights the port and the associated link/activity LED.
1.2.1. Fiber Optic Transceiver Orientation and Connection
Depending on the order code of the product, the M2000 series products can be equipped with several
different types of fiber optic ports. The Transmit (TX) and Receive (RX) connections of each port must
be properly connected and matched for proper link and operation. Modules populated on the top row of
the device typically have locking mechanisms or tabs towards the top of the unit. Modules located on
the bottom row of the device have locking mechanisms or tabs towards the bottom of the device.
The drawings in the following figures show each fiber optic connector style with a side and top view
to allow the user to identify the proper cable connection orientation. If modules are populated on the
bottom row of the device, the transceiver orientation will be reversed (i.e. RS and TX will be reversed).
The M2000 series products are equipped with a versatile display panel, shown in Figure 1.5, “M2000
Series LED Display Panel”, which is designed to provide quick status information for each port, as well
as the entire device to allow for simple diagnostics and troubleshooting. It features:
• RS232 console port for "out of band" console access and configuration
• Power supply and Alarm status indicators
• Convenient port status indicators conveying Link-Activity, Duplex, or Speed via push-button control.
• System reset via push-button if held for 5 seconds
Figure 1.5. M2000 Series LED Display Panel
Device status LEDs exist to provide a quick visual indicator to operators for operational status of the
unit. Table 1.1, “LED Display - Device status LED behavior definition” defines the possible LED colours
and the corresponding description.

The port-based LEDs can be cycled between three display modes: Status, Duplex, and Speed. Pushing
the mode button causes the display mode to be cycled.
The M2000 series products can be ordered with Panel mount chassis. This option involves the use of
the panel adapters to be mounted on each side of the chassis enclosure. See Figure 2.1, “M2100 Panel
Figure 2.2. M2000 Series Phillips Screw Terminal Block
The M2000 Family supports dual redundant power supplies - "Power Supply 1 (PS1)" and "Power
Supply 2 (PS2)". The connections for PS1, PS2 and the fail-safe relay are located on the terminal block
as shown in Figure 2.2, “M2000 Series Phillips Screw Terminal Block”.
The M2000 Family chassis ground connection, shown in Figure 2.3, “Chassis Ground Connection”,
uses a #6-32 screw. It is recommended to terminate the ground connection in a #6 ring lug, and to use
a torque setting not exceeding 1.7 Nm (15 in.lbs).
Figure 2.3. Chassis Ground Connection
The M2000 Family is equipped with a Phillips Screw Terminal Block. The Phillips Screw Terminal Block
has Phillips screws with a compression plate allowing either bare wire connections or crimped terminal
lugs. RuggedCom recommend the use of #6 size ring lugs to ensure secure, reliable connections
under severe shock or vibration. The terminal block has a safety cover which must be removed via
two Phillips screws before connecting any wires. The safety cover must be re-attached after wiring to
ensure personnel safety. Refer to Table 3 below for a description of each terminal as well as sections
5.2.1 through 5.2.3 for wiring examples.

• For dual DC power supplies, Separate circuit breakers must be installed and separately
identified.
• Equipment must be installed according to the applicable country wiring codes.
2.3. Dielectric Strength (HIPOT) Testing
For dielectric strength (HIPOT) testing in the field, users must remove the metal jumper located
on terminal 2, 4, and 6 of the power supply terminal block. This metal jumper connects transient
suppression circuitry to chassis ground and must be removed in order to avoid damage to transient
suppression circuitry during HIPOT testing. Figure 2.9, “Dielectric Strength (HIPOT) Testing” shows the
proper HIPOT test connections and should be followed to avoid damage to the device.
2.4. Failsafe Alarm Relay Wiring and Specifications
The "Failsafe" output relay is provided to signal critical error conditions that may occur on the M2000
series switches. The contacts are energized upon power up of the unit and remain energized until a
critical error occurs. The proper relay connections are shown in Figure 2.9, “Dielectric Strength (HIPOT)
Testing”. One common application for this output is to signal an alarm if a power failure or removal of
control power occurs.
Figure 2.10. Failsafe Alarm Relay Wiring
2.5. Console Port Wiring
A RS232 console port for configuration and management of the device is located on the LED display
module shown in Figure 2.11, “Console port location on display board”. This port is intended to be
a temporary connection during initial configuration or troubleshooting and allows for direct access
to the serial-based management console. The connection is made using the DB9-Female to RJ45
console cable included in the device packaging shown in Figure 2.12, “M2000 Console cable”. Console
connection settings are: 57600 baud, no parity bits, 8 data bits, and 1 stop bit.

2.6.2. Protection on Twisted-Pair Data Ports
RuggedCom does not recommend the use of CAT-5 cabling of any length for critical real-time substation
automation applications. However, transient suppression circuitry is present on all copper ports to
protect against damage from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1
conformance. This means that during the transient event communications errors or interruptions may
occur but recovery is automatic.
RuggedCom also does not recommended to use these ports to interface to field devices across
distances which could produce high levels of ground potential rise, (i.e. greater than 2500V) during line
to ground fault conditions.
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet communications over
distances of up to 100 meters using all 4 pairs in category 5 (or higher) balanced unshielded
twisted-pair cabling. For wiring guidelines, system designers and integrators should refer to the
Telecommunications Industry Association (TIA) TIA/EIA-568-A wiring standard that characterizes
minimum cabling performance specifications required for proper Gigabit Ethernet operation. To
ensure reliable, error-free data communication, new and pre-existing communication paths should be
verified for TIA/EIA-568-A compliance. Table 2.5, “Cabling Categories And 1000Base-TX Compliance”
summarizes the relevant cabling standards.

Follow these recommendations for copper data cabling in high electrical noise environments:
• Data cable lengths should be as short as possible - ideally limited to 3m (10') in length. Copper data
cables should not be used for inter-building communications.
• Power and data cables should not be run in parallel for long distances, and should be installed in
separate conduits. Power and data cables should intersect at 90° angles when necessary to reduce
inductive coupling.
• Shielded/screened cabling can optionally be used. The cable shield should be grounded at one single
point to avoid the generation of ground loops.
The following sections detail fiber optic specifications on ports that can be ordered with the M2100
series Ethernet switch. The user determines the type of optics at time of ordering, and can determine the
modules installed on a particular unit by reading the factory data file via the RuggedSwitch ROS™ user
interface. The following sections detail specifications of fiber optic modules in two general categories,
Ethernet / Fast Ethernet (10/100 Mbps) and Gigabit Ethernet (1000Mbps).
The dual-port fast Ethernet optical specifications for M2100 ports 1-8 and 13-20 are shown in the
following table organized by module order code. Module order codes are contained within each product's
