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 9476 Ethernet 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.

DESCRIPTION

The 9479-ET(G)-CSL is an Intrinsically Safe (IS) WLAN AP/Bridge Module suitable for Zone 1 / Zone 21 mounting, (Zone 0 / Zone 20 with a suitable Ex ia Power Supply). It may be configured as either an AP or Client/Bridge. Also supporting either 2.4GHz or 5GHz operation further extends its range of applications. There are 2x RJ45 (LAN) ports that support 10/100/1000 IS Ethernet connections – these can allow ‘daisy-chaining’ of units together. Power (12V DC) is supplied to the module either locally or using Power over Ethernet (PoEx) from the LAN port – This requires the PoEx output to be wired to the Supply Input terminals by the user ( -ET version only). The compact and cost effective design makes it the ideal choice for many applications:

Petrochem Process Monitoring & Control…
Mining Underground Communication Links, PLC and Machine Monitoring

Electrical connections are via cage-clamp and/or screw type plug/socket terminals along with RJ45 type connectors for the Ethernet LAN ports.

Network Setup

To begin configuring the unit, the Default IP Address is 192.168.1.253

This page displays the current network configuration.

• Click the ADD NETWORK button to create a new IP network.
• Click the REMOVE button under the ‘action’ heading to remove the selected network.
• Click the EDIT button under the ‘action’ heading to open the network configuration page.

Network Configuration

Once you have clicked the EDIT button, you will see the network configuration page,
here you can set all the information about your network.

General Setup:

Enable Interface: Tick this box to enable the selected network interface.
Network Description: This entry is to provide an identification to your network
Protocol: Choose DHCP if you have a DHCP server in the network and you want to assign an IP address to the AP. Choose Static if you do not have a DHCP server in the network or if you need a fixed address to the interface.
Note – You cannot choose DHCP if you have enabled the DHCP server option on the
DHCP page; the AP cannot be both a DHCP client and a DHCP server.
IPv4 Address: Only available in static mode. The IP address of the AP on the local network. Assign any unused IP address in the range of IP addresses available for the LAN
IPv4 Netmask: The subnet mask of the LAN
Default IPv4 gateway: The IP address of the router on the local area net work.
DNS Server(s): The IP addresses of the DNS server(s) you want to use. If you selected the DHCP protocol, you can choose to use the value defined in the menu TOOLS/System, or you can define a new HOSTNAME, specific to this network.

Interfaces Setting:

Bridge Interfaces: If checked, all interfaces in this network are linking with the software equivalent of an Ethernet switch.
Enable STP/RSTP: If checked the STP/RSTP will be activated on this bridge. If you choose to not use STP/RSTP, you have to set up your devices to avoid network loops, by yourself.
Enable LLDP Forwarding: Check this box if the internal bridge must forward the LLDP multicast frame.
Bridge VLAN: Enable VLAN management in the bridge.
Interface: This is the list of available network interfaces. Disabled (greyed) interfaces  are already used in another network. For Bridge networks, select all the interfaces you want to bridge together in to the LAN being configured. For simple networks, select the one interface to configure.

Advanced Settings:

Network Persistence: When this option is enabled, the IP setting (routes, gateway, virtual interfaces) remains persistent when the physical interface loses its connection. Default value is enabled for static IP, and disabled for DHCP

Wi-Fi Setup

This page allows the user to configure the wireless network settings, by default the radio will be disabled and you will need to turn in on.

Country: The regulation rules of the selected country will determine the channels and transmission powers you can use. Additionally, in the client role, the product will use the country provided by the AP in its beacons.
Under the ‘actions’ heading, you can click the buttons ‘EDIT’ and ‘REMOVE’.
Click REMOVE to remove the selected SSID.
Click EDIT to open the radio windows and edit this SSID’s Properties.

Device Configuration:

General Setup:
This selection gathers all the settings that are common to each SSID you may create on this radio.
Enable Device : If this box is checked, the radio card is enabled and is able to communicate. Uncheck it to disable the radio.

802.11 Mode:
The 802.11g+n mode operates in the 2.4GHz band and is compatible with 802.11g and 802.11n devices. The 802.11a+n mode operates in the 5GHz band and is compatible with 802.11a/h and 802.11n devices. The 802.11ac+n mode operates in the 5GHz band and is compatible with 802.11ac, 802.11a/h and 802.11n devices.
Note – A unit configured in 802.11ac+n/802.11a+n cannot communicate with another one configured in 802.11g+n mode because they are using different frequency ranges. HT (high throughput) mode: In HT mode, you can aggregate adjacent channels (2 in 802.11n, 2 or 4 in 802.11ac) in order to increase bandwidth. One of the channels is the one selected in the channel section (see below). The second one may be the one directly below or directly above. If you choose 20MHz, only one channel will be used at a time.
Automatic channel select (ACS): Depending on the unit role, the channel can be selected automatically; AP Role: At start up, the AP will select the channel among all the ones allowed in your country. In order to limit the choice to specific channels, do not check ACS, but use the channels multi- selection box instead.
Client Role: The client will scan all channels allowed in your country. In order to limitthe channel scan list, do not check ACS, but use the channels multi-selection box instead. If the client is set in roaming mode, this channel list is superseded by the one in the roaming tab.

Other Roles: The other roles, (mesh portal, ad-hoc) support only one channel, this parameter is not available and you must select a channel in the dropdown box.
Channel: According the selected 802.11 mode and the regulation rules of the selected country, a list of channels is available for selection. This is not used for infrastructure client modes, as they use all the allowed channels for scanning. In some cases, a single radio card can handle multiple Wi-Fi roles simultaneously. In this case and ‘client’ function must be set to only scan the common channel. You can select several channels so that the AP will select the cleanest one and will be able to switch to another if a radar is detected on the current one. To select multiple channels, use Ctrl + click.

Advanced Settings

Max Transmit Power: The transmit power is normally set automatically based on the regulation rules for the given channel and the capabilities of the radio card. This option sets an upper bound on the transmit power. The transmit power is distributed between the configured antennas.

Antennas: NOTE: Improved RX signal strength and full TX power is achieved only buy using two antennas and selecting “All” for this option. Both are also required for 802.11n MIMO mode. For single antenna use select “Only #1” and connect the antenna to the AUX socket, however performance will be reduced with a single antenna.

Qos Profile: This option allows choosing between the two Qos profiles.

Distance optimization: Use this option if your link covers a long distance, it will update the internal timeouts.

Beacon interval: This option allows configuring the interval between two beacon frames.

Fragmentation threshold: This option configures the maximum 802.11 frame size in 802.11a/b/g mode in bytes. Frames that exceed this threshold are fragmented.

RTS/CTS threshold: The Wi-Fi standard uses the RTS/CTS protocol to avoid collision in the air; this option defines the size of the frames subject to this protection. Use RTS/ CTS when you have interference on your channel or a poor performance on the Wi-Fi.

Retry settings: Unicast data frames are normally acknowledged. If the transmitter does not receive the acknowledgment, it must resend the frame. In 802.11n mode, several frames can be aggregated into one big frame called an A-MPDU. Independent frames are acknowledged by an individual ACK frame, while A-MPDU frames are acknowledged by a single ‘Block acknowledge’ frame containing one acknowledgment for each subframe in the A-MPDU. When you check this option, you can set the number of retries.

Short Retry: This is the number of retries for a physical data frame.
Long Retry: This is the number of retries for a physical data frame sent with the RTS/  CTS protocol Aggregate Retry: This option configures the number of retries for a frame aggregated  into an A-MPDU.

Interface Configuration:
This section is duplicated for each SSID; settings only apply to the selected SSID. General setup:

Role: The unit has the following supported roles;

•  Access Point
• Isolating access point
• Client (connecting at an access point)
• Mesh 802.11s
• Point to multipoint station (ad-hoc)
• SRCC

ESSID: This is the Wireless network name.
Maximum association: Specifies the maximum number of clients allowed to connect on the Access Point.

Hide ESSID: This option allows you to not broadcast the SSID on the network. This means that your clients will need to know the SSID beforehand, since scanning will not real this SSID on the AP.

Network: This option allows selecting the network where the interface is added.
Mesh ID (only in mess mode): This option replaces the ESSID when the Mesh mode is selected.

General setup client mode:

Multiple ESSIDs: When this is checked, a multi-selection field, (Wireless network nicknames), replaces the single ESSID field. You can select several SSIDs with their security parameters and the client will associate to any AP advertising one of the combination. In case several matching APs are in range, you can prioritize the SSIDs. When using multiple ESSIDs, the roaming features are not available; the security is defined together with the corresponding ESSID in a separate menu.

Wireless Security:
This menu allows you to choose the type of wireless security you want to apply on this SSID. The different security schemes are;

• No Encryption
• WEP Open System
• WEP Shared Key
• WPA-PSK
• WPA2-PSK
• WPA-PSK/WPA2-PSK Mixed Mode
• WPA-EAP
• WPA2-EAP
• WPA-LEAP
• WPA2-LEAP
  Depending on which security option you choose, a range of options will appear that you must configure.

DHCP Server

General Setup:

Ignore interface: If checked, the DHCP server will be disabled on the selected interface.
DHCP pool first address (if enabled): First IP Address of the DHCP pool. This is interpreted as an offset relative to network address.
DHCP pool size (if enabled): Maximum number of leased addresses.
Lease time (if enabled): This represents the time during which a given IP Address remains valid. After that time, the client needs to renew his lease.

Advanced Settings

Dynamic DHCP: If unchecked, only static leases will be authorized.
Force: By default, the DHCP service doesn’t start if it detects the presence of another DHCP server on the network. If this option is checked, the DHCP server wont check for another server before start.
IPv4 Netmask: This option override the default netmask value sent to DHCP clients.
DHCP Options: This field allows you to enter an additional DHCP option (enclosed into quotes). Syntax depends on the option itself.

Static Lease:

This option allows to always give the same predefined IP Address according to the MAC address.
