1. FEATURES
♦ Intrinsically Safe ATEX / IECEx certified / FM / FMC approved
♦ Ga Ex ia IIC T4 GD (surface), Ma Ex ia I M1 (mining)
♦ Zone 1/ Division 1 mounting in a suitable enclosure
♦ Input voltage: 12V dc nominal (10 – 15.4V)
♦ Input current 200mA
♦ Extended temperature range (–20°C…+70°C)
♦ PoEx™ - “Power over Ethernet” power sourcing equipment - distributes device supplies via the RJ45 ports*
♦ 5x Port 10/100Mb Ethernet twisted pair (Cat5e) RJ45 Connections (100m max)
♦ Status LED’s For :
‘Power On’
Copper UTP ‘Half/Full Duplex’ (each port)
Copper UTP ‘10Mbps/Activity’ (each port)
Copper UTP ‘100Mbps/Activity’ (each port)
♦ 10/100Mbps Half/Full Duplex with Auto-Negotiation
♦ Supports MDI / MDI-X auto crossover (easy cascading of switches with standard straight
connected 1:1 cables)
♦ Broadcast storm protection – eliminates network overload caused by excessive ‘broadcast’ and
‘multicast’ packets.
♦ Intelligent Routing - Automatic address learning, aging and migration
♦ Supports IEEE 802.3: 10Base-T, 100Base-TX
♦ IEEE 802.1q Tag/Port based VLAN, Quality of Service (QoS) priority
♦ Programmable Managed features (Serial port) VLAN, Rate Limiting, Port Mirroring etc
♦ DIN-rail mounting module
*Note – PoEx is a simple adaptation of the IEEE 802.3af Power over Ethernet (PoE) standard to
bring the benefits to the 9400 Range of Hazardous Area devices. This allows two spare pairs in the
existing Cat5e cable to distribute the power supply from a 9466-ETEthernet Switch (Power Sourcing
Equipment – PSE) to each of the devices connected to its five ports (PD – Powered Device). This
adaptation is necessary due to restrictions for Hazardous Area use. It is not implied that the device
conforms to the 802.3af (PoE) standard.
9466-ET - Managed Ethernet Switch

INM9466 rev 3
2. DESCRIPTION
The 9466-ET 10/100Mbps Managed Layer 2 Ethernet Switch allows the interconnection of other
9460-ET Series networking modules via its 5x ports, it also enables an Ethernet network to cover
a greater distance, either using Cat5e cable or fibre-optic for longer spans, this is down to the low
latency ‘store and forward’ mechanism integral to the switch which ensures that the stringent timing
associated with Ethernet is maintained. With the 9466-ET switch, each connection is effectively a
‘point-to-point’ network segment unlike the older generation hubs that were simple ‘dumb’ repeaters
– these needed to impose a limit on overall network length to ensure proper collision detection, this
limit is overcome by using the 9466-ET.
The 9466-ET switch can also distribute power to compatible devices connected to each of its five
ports via the RJ45 Cat5e cables (PoEx), this eliminates the separate power supply cable to the
device simplifying installation and maintenance.
The default mode of operation is a 5 port unmanaged switch with auto negotiation. However the
onboard EEPROM memory can be configured via the serial RS232/TTL port either in the Safe Area,
using a PC; or in the Hazardous Area using the 9461-ET Ethernet Gateway as its host processor.
Features such as Programmable Rate Limiting, VLAN support Port Mirroring and Forced Speed and
Duplex settings may be configured in this way if required. The 9461-ET module can also perform its
usual function of a serial communications gateway (eg: serial Modbus to Ethernet conversion) whilst
giving ‘online’ access to the managed features of the 9466-ET switch over the Ethernet network,
including the MIB counters for each port.
3. INSTALLATION
WARNING: This equipment must be installed, operated and maintained only be trained competent
personnel and in accordance with all appropriate international, national and local standard codes
of practice and site regulation for intrinsically safe apparatus and in accordance with the instructions
contained here. See also Sections 19, 20 & 21 for approvals and important conditions of safe use.
3.1 Protection
The module requires mounting within an enclosure providing a degree of protection of at least IP6x,
in accordance with EN60529 and in a manner that does not impair the existing creepage and
clearance distances. The enclosure must also comply with the requirements of Clauses 7 and 8 of
EN50014 and be sealed to prevent the ingress of dust.
