Mounting the Device
The RSG2488 is designed for maximum mounting and display flexibility. It can be ordered with connectors that
allow it to be installed in a 48 cm (19 in) rack, 2.5 cm (1 in) DIN rail, or directly on a panel.

4 Mounting the Device to a Rack
NOTE
For detailed dimensions of the device with either rack, DIN rail or panel hardware installed, refer to
Chapter 5, Dimension Drawings.
The following sections describe the various methods of mounting the device:
•Section 2.1.1, “Mounting the Device to a Rack”
•Section 2.1.2, “Mounting the Device on a DIN Rail”
•Section 2.1.3, “Mounting the Device to a Panel”
Section 2.1.1
Mounting the Device to a Rack
For rack mount installations, the RSG2488 can be ordered with rack mount adaptors pre-installed at the front or
rear of the chassis. Additional adaptors are provided to further secure the device in high-vibration or seismically
active locations.
To secure the device to a standard 48 cm (19 in) rack, do the following:
1. Make sure the rack mount adaptors are installed on the correct side of the chassis.
• To make the modules and ports accessible, install the rack mount adaptors at the rear of the chassis
• To make the management ports and LEDs accessible, install the rack mount adaptors at the front of the
chassis
NOTE
The chassis features multiple mounting holes, allowing the rack mount adaptors to be installed up
to 25 mm (1 in) from the face of the device.

Figure 2: Rack Mount Adaptors
1. Rear 2. Front 3. Rack Mount Adaptor
2. If required, install adaptors on the opposite side of the device to protect from vibrations.
3. Insert the device into the rack.
NOTE
Since heat within the device is channeled to the enclosure, it is recommended that 1 rack-unit
of space, or 44 mm (1.75 in), be kept empty above the device. This allows a small amount of
convectional airflow.
Forced airflow is not required. However, any increase in airflow will result in a reduction of ambient
temperature and improve the long-term reliability of all equipment mounted in the rack space.
4. Secure the adaptors to the rack using the supplied hardware.

Mounting the Device on a DIN Rail
For panel installations, the RSG2488 can be ordered with panel/DIN rail adaptors pre-installed on each side of
the chassis. The adaptors allow the device to be attached to a panel using screws.
To mount the device to a panel, do the following:
1. Align the adaptors with the DIN rails and slide the device into place.

Section 2.2
Installing/Removing Power Supplies
The RSG2488 supports dual redundant AC and/or DC power supplies that can be installed in any combination.
IMPORTANT!
• In a high AC/DC and low DC (24/48 V) power supply arrangement, either power supply can be
installed in slot PM1 or PM2. However, if a high AC/DC power supply is installed in slot PM1, the
high AC/DC wiring must be connected to the high terminal block PM1 terminals. If a low DC power
supply is installed in slot PM1, the loww DC wiring must be made to the low terminal block PM1
terminals. High voltage wiring is always made to the upper Hi terminal block and low voltage (24/48
V) wiring is always made to the lower Lo terminal block.
• Use only #16 gauge wiring when connecting terminal blocks.
• A circuit breaker rated no higher than 20 A must be installed between the device and the supply
mains.
• Whenever possible, use a separate circuit breaker for each power supply.
• For maximum redundancy in a dual power supply configuration, use two independent power
sources.

Cabling Recommendations
Before connecting the device, be aware of the recommendations and considerations outlined in the following
sections:
•Section 2.5.1, “Protection On Twisted-Pair Data Ports”

Chapter 2
Installing the Device
RUGGEDCOM RSG2488
Installation Guide
12 Protection On Twisted-Pair Data Ports
•Section 2.5.2, “Gigabit Ethernet 1000Base-TX Cabling Recommendations”
Section 2.5.1
Protection On Twisted-Pair Data Ports
RuggedCom does not recommend the use of copper cabling of any length for critical, real-time substation
automatation applications. All copper Ethernet ports on RuggedCom products include transient suppression
circuitry to protect against damage from electrical transients and conform with IEC 61850-3 and IEEE 1613 Class
1 standards. This means that during a transient electrical event, communications erorrs or interruptions may
occur, but recovery is automatic.
RuggedCom also does not recommend using copper Ethernet ports to interface with devices in the field across
distances that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-ground
fault conditions.
Section 2.5.2
Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet communications over distances of
up to 100 m (328 ft) 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.
The following table summarizes the relevant cabling standards:
Table 1: Cabling Categories and 1000Base-TX Compliance
Cabling Category 1000Base-
TX Compliant Required Action
< 5 No New wiring infrastructure required.
5 Yes Verify TIA/EIA-568-A compliance.
5e Yes No action required. New installations should be designed with Category 5e or higher.
6 Yes No action required.
> 6 Yes Connector and wiring standards to be determined.
Follow these recommendations for copper data cabling in high electrical noise environments:
• Data cable lengths should be as short as possible, preferrably 3 m (10 ft) 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 be used when required. The cable shield should be grounded at one single
point to avoid the generation of ground loops.
