2 Overview and ordering data
2.1 Description
FL SWITCH EP74… advanced modular managed network switches provide an adaptable
platform to meet the electric power industries increasing requirements for scalable network
performance, uptime and security.
The modular 19-in. rack mount switch is hardened for areas heavily affected by EMI, such
as switchgear, transformer stations, and local substations. The switch works reliably under
extreme -40°C to +75°C/85°C environmental conditions and complies with the IEC 61850-
3 Ed 2, and IEEE 1613 specifications. The expandable “all Gigabit capable” architecture
combines cost effective answers for near term needs with upgrade paths for port quan-
tity/bandwidth and functions. A powerful Layer 2 and Layer 3 feature set with hardware-
based IEEE 1588 V2 PTP synchronization, based on the IEC61850-9-3 Utility Power Profile,
provides extensive options to meet changing performance and security needs.
The 28-port switch has four module slots. Three slots accept 10/100/1000 Mbps port mod-
ules (up to eight ports) for device connections, and a fourth slot supports a four-port SFP
module with 1 or 10 Gigabit up-link or device connections. SFP module options provide fur-
ther single point TX/fiber connection customization while allowing for electrically isolated
and secure communication lines between the control house and equipment throughout the
station.
Power is provided by redundant, modular power supplies. The modules are designed for
power source flexibility (AC/DC) and allow for hot-swappable replacement for uninterrupted
24/7 operation.
Power supply modules must be purchased separately.

Heat generated by the switch is channeled outwards from the enclosure. For improved con-
vectional airflow, make sure there is at least one rack unit (1U) or 44 mm of space around
all sides of the device or between the devices on the rack.
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 the equipment mounted in the
rack space.
The color LCD displays switch revision information and port status.
The SecureDigital (SD) port cover covers the following:
– SD card slot #1 (top) is for factory use and is disabled.
– SD card slot #2 (bottom) is available for storing up to 32 GB of Syslog event files.
– The management port, a 10/100 Base-T Ethernet port, that is used as an out-of-band
factory service port. It is disabled by default and not available for user access.
– Power status LEDs indicate the status of the installed power supply modules.

4.1 Prevention of electrical discharge damage
The device components are subject to electrostatic discharge (ESD) damage. ESD dam-
age can cause intermittent or complete component failures. Potentially destructive static
voltages can happen during handling of plastic or foam packing material, or when moving
components across plastic or carpets.
If a grounding strap is not available, then to ground yourself, touch the exposed bare metal
of the device with the other hand immediately before inserting the component into the de-
vice.
Avoid contact between the component that is subject to ESD damage and clothing. ESD
voltages emitted from fabric can damage components.
When removing or installing a component that is subject to ESD damage, always place its
components upside on an antistatic surface, in an antistatic card rack, or in an antistatic
bag. If you are returning a component, place it in an antistatic bag before packing it.
4.2 Unpacking
Inspect the package for damage before opening.
Open the package and visually inspect all items for issues.
Confirm that all items are available.
– Switch base packaged items
– Switch within a protective bag, with one power supply slot covered
– Four mounting brackets with screws to attach to the switch base
– Console cable: RJ45 to D-SUB 9
– Installation instruction sheet
– Power and port module packaged items
– Installation instruction sheet
The blank slot filler module comes with screws for securing to the switch base.
If there any missing or damaged items, contact your local Phoenix Contact office.

4.3 Electrical/mechanical hazards prevention
DANGER: Electrocution hazard
Always disconnect the power at the supply source before connecting or disconnect-
ing wires to the terminal block. The cover must be installed over the terminal block be-
fore applying power.
If redundant power supplies are used, ensure that both power supply sources are dis-
connected.
CAUTION:
This equipment is intended only for use in a restricted access area.
Access to the battery located inside the unit is prohibited.
Access to wiring terminals and replaceable modules is restricted to skilled persons
only.
For improved convectional cooling and airflow, make sure that there is at least one rack unit
(44 mm) of space exists between devices on the rack.
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 the equipment mounted in the
rack space.
When installing the device in a closed or multi-device rack, be aware that the ambient tem-
perature of the rack may be higher than the ambient temperature of the room. Make sure the
rack is installed in a suitable environment that can withstand the maximum ambient tem-
perature generated by the rack.
Do not exceed the maximum number of devices or weight restriction specified by the rack
manufacturer.
Do not overload the supply circuit. Refer to the overcurrent protection and power supply rat-
ings specified by the rack manufacturer.
Make sure the rack and all devices have a proper ground-to-Earth connection. Pay particu-
lar attention to power supply connections other than direct connections to the branch circuit
(e.g. power strips). Ensure that the rack mount adapters are installed on the correct side of
the chassis.
Do not store the switch in locations where it will be subject excessive dirt and dust and high
humidity. Conformal coating is recommended for humid/moist applications.
