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 highlights the
port and the associated link/activity LED.
3.2.1 Fiber Optical 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 optical 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. RX and TX will be
reversed).
The M2000 series products are equipped with a versatile display panel, shown in Figure 5, 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 7: M2000 Series Philips 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 7.
The M2000 Family is equipped with a Philips Screw Terminal Block. The Philips Screw Terminal
Block has Philips 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 4.2.1 through 4.2.3 for wiring examples.
Table 3: M2100 Power terminal block connection description
power source is DC or to the (Live) terminal if the power
source is AC.
PS1 Surge Ground is connected to the Chassis Ground via
a jumper on the terminal block. Surge Ground is used as the
ground conductor for all surge and transient suppression
circuitry. NOTE: Surge Ground must be disconnected from
Chassis Ground during HIPOT (dielectric strength) testing.
PS1 Neutral / - is connected to the negative (-) terminal if
the power source is DC or to the (Neutral) terminal if the
power source is AC.
Chassis Ground is connected to the Safety Ground
terminal for AC inputs or the equipment ground bus for DC
inputs. Chassis ground connects to both power supply surge
grounds via a removable jumper.
PS2 Live / + is connected to the positive (+) terminal if the
power source is DC or to the (Live) terminal if the power
source is AC.
PS2 Surge Ground is connected to the Chassis Ground via
a jumper on the terminal block. Surge Ground is used as the
ground conductor for all surge and transient suppression
circuitry. NOTE: Surge Ground must be disconnected from
Chassis Ground during HIPOT (dielectric strength) testing.
PS2 Neutral / - is connected to the negative (-) terminal if
the power source is DC or to the (Neutral) terminal if the
power source is AC.
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 11 shows the proper HIPOT test connections
and should be followed to avoid damage to the device.
4.4 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 12. One
common application for this output is to signal an alarm if a power failure or removal of control
power occurs.
A RS232 console port for configuration and management of the device is located on the LED
display module shown in Figure 13. 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 14. Console connection settings are: 57600 baud, no parity
bits, 8 data bits, and 1 stop bit.

After initial configuration, the RuggedSwitch device can be configured via a number of new
mechanisms such as Telnet, and the built-in web server. Consult the RuggedSwitch ROS User
Guide for further details.
NOTE: This port is not intended to be a permanent connection and the cable shall be less than 2m
(6.5 ft) in length.
The M2100 may have several 10/100/1000BaseTX ports that allow connection to standard CAT-5
UTP cable with Micro-D connectors. Figure 15 shows the Micro-D port pin configuration.
The M2100 series switches may have several 10/100BaseTX ports that allow connection to
standard CAT-5 UTP cable with RJ45 male connectors. The RJ45 receptacles are directly
connected to the chassis ground and can accept shielded CAT-5 cables. If shielded cables are
used, care must be taken to ensure the shielded cables do not form a ground loop via the shield
wire and the RJ45 receptacles at either end.
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 1000Mbit/s Ethernet communications over
distances of up to 100 meters using 4 pairs of category 5 (or higher) balanced unshielded twistedpair 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 communications, new and pre-existing communication paths should
be verified for TIA/EIA-568-A compliance. Table 5 summarizes cabling standards available today

In general the following recommendations should be followed for copper data cabling in high
electrical noise environments:
• Data cable lengths should be as short as possible, ideally limited to 3m (10ft) 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 ideally 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 optical 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 ROSTM user interface. The following sections detail specifications of fiber optic
modules in two general categories, Ethernet / Fast Ethernet (10/100Mbps) 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
