*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.

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.

As the 9466-ET Ethernet switch supports Auto MDI/MDI-X, a straight connected RJ45 Cat5e cable
is used to connect to any device.
It is recommended that Cat5e cables for Hazardous Area Zone 1 use are ‘Blue’ in colour and are
of good quality (see accessories section), the Safe Area cables being a colour other than blue to
aid identification.

4 PC PACKAGE REQUIREMENTS
In order to run the package on a PC, the following minimum system configuration is required:-
• Pentium® 3 Processor or Equivalent
• 256 Mb RAM minimum
• Windows® 98(or higher)
• Serial Communications Port
5 SOFTWARE INSTALLATION
Note: Sections 5 through to 15 are relevant only if you require the 9466-ET switch
to operate in the managed mode.
The 9466-ET Ethernet switch management software is provided on a CD along with the hardware.
If the CD is not available for some reason, download the software from the Industrial Networks
section of MTL’s website at www.mtl-inst.com.
If installing from the CD - Place the CD into the CD or DVD drive on a PC. If the Setup
application does not Autorun then use Start|Run from the Windows menu and run the setup.exe
application on the CD to launch the installation program.
If installing from downloaded files - Unzip the file into a temporary directory, then run the
resulting setup.exe application in that directory to launch the installation program.
In either case, this is a conventional installation program that requires the user to specify a
destination directory for the application software, after which the setup will continue. Follow the
on-screen instructions to complete the installation.
6 COMMUNICATING WITH THE 9466-ET
6.1 In the safe area
Connect the 9466-ET Ethernet Switch to your PC using the CAB9466 RS communications lead that
is supplied with the switch. The 9-pin minature D-type connector should be plugged into a Serial
Communications (COM) port on the PC and the other end of the cable should be plugged into the
RS232 connector on the front panel of the 9466-ET Switch. Apply 12V dc power to the switch and
then open the Configuration Software application.
6.2 In the hazardous area
If the 9466-ET is installed in an intrinsically safe system in the hazardous area then the 9461-ET
Etthernet Gateway is required to connect to the 9466-ET from the safe area. Set up the 9461-ET as
instructed in its manual
7 LAUNCHING THE PROGRAM
To run the program, double click the 9466-ET Management icon. A splash screen, of the type shown

8 MAIN SCREEN
The following screen is the main page of the software and appears upon launch. On the left it shows
the status of the switch along with version numbers.
To the right of the status is the port usage. This provides an easy to view insight into the amount of
throughput on the switch and whether the Ethernet Architecture needs any maintenance.
Below these vertical bars are the settings for each of the ports, the link Speed/Duplex Mode,
Broadcast Storm Protection, Back Pressure, Learning and Port ON/Off.
At the side there are the options regarding Aging. This allows for aging to be enabled, with Link
Change or Fast and whether Aggressive Back Off is required.
In order to alter any of the parameters, Value Editing must be enabled. This is done by clicking on
the Enable Value Editing Menu Bar option and entering the password: 216231
Note: Value editing permission times-out after approximately 5 minutes.
After modifications are made they need to be sent or saved to the switch. Sending to the switch is
only temporary and will be lost on a power down whereas saving is permanent.
Also on this, and every, page is the status bar at the bottom. This records the last event that has
happened. Events can include Switch Offline, Settings Saved or Sent etc.
8.1 Menu Bar
At the top of the window is the menu bar, which gives the following options:-

9 VLAN
The 9466-ET supports 16 different tag-based VLANS. There are 12 bits in the IEEE802.1Q VLAN
ID field, allowing for 4096 different VLAN ID’s. The 9466-ET supports 16 active VLANs. Any one
of the 4096 available VLAN ID’s can be specified as one of the active VLANs. If a non tagged
packet or a null VID packet is received the 9466-ET will use the ingress ports programmable default
VID for look up.
Click Enabling Value Editing and enter the password. In order to use the 802.1Q VLAN, it must be
enabled by selecting the Enabled 802.1Q VLAN checkbox.
As can be seen on the above screen the 16 VLANs can be configured with an ID, port members
and whether currently active.
Also parameters for each of the ports can be set at the bottom, Tag Insertion, Tag Removal, Ingress
Filtering Enable, Discard Non PVID Packets and the Ports Default VLAN ID.
Again as seen on the other page, once the settings have been altered you can Save or Send them
to the switch.

10 RATE LIMIT
The 9466-ET supports programmable rate limiting on a per port basis. After password entry,
Transmit and receive rate limits for each port can also be programmed independent of one another.
The user can program a different rate limit for high and low priority packets. The rate limit can be
programmed up to the line rate in increments of 32,768 bps.
On the above screen the rates can be set in Mbps for both low and high priority messages. To limit
High priority messages ensure the Disable Priority check boxes are not selected. The rate limits can
be enabled by selecting the check boxes on the appropriate limit. The priority for each port can be
set to be Diffser, 802.1P, Port Based or None.
Again as seen on the previous pages, once the settings have been altered you can Save or Send
them to the switch.

11 MIRRORING
The 9466-ET provides a facility to mirror (i.e.copy) information on one, or more, ports to other
ports. Three options are available after Enabling Value Editing using the password.
• “Receive only” port mirroring
Information received on a port can be mirrored (copied) to another port(s).
• “Transmit only” port mirroring
Information transmitted on a port can be mirrored to another port (s).
• “Receive and Transmit” port mirroring
Information received on a port and information transmitted on a port can be mirrored to another
port(s).
Specify the port(s) by checking the boxes for the ports. In the first column (Mirror Port) you specify
the ports to receive the mirrored information, then check boxes in the second and third columns to
specify which ports are to mirror their Tx or Rx data respectively.
