3.2 Managed Ethernet extender
Remote diagnostics via IP
With the Managed Ethernet extenders, you can diagnose all devices and paths centrally via
IP. There are two options available for remote diagnostics:
– Web-based, via the web server on the device
– Via SNMP using separate software, e.g., an MIB browser (not supplied as standard)
SNMP
In the web-based management, activate the SNMP traps. You can send the following event
messages:
– Device start
– Ethernet connection status changed
– DSL connection status changed
– Surge protection status changed
– DSL ring error
– User access data (admin) changed
– SD card has been inserted or removed
High-quality surge protection
PLUGTRAB PT-IQ is the forward-looking surge protection system from Phoenix Contact.
Your advantage: multi-stage monitoring of protective devices. This means that failures can
be foreseen.
– Integrated, replaceable SHDSL surge protection
– Automatic notification when replacement threshold reached or in the event of overload
3.3 Functions in firmware version 5.xx
Virtually separate critical IP networks with VLAN
All Ethernet extenders in the TC EXTENDER... product family support VLAN (Virtual Local
Area Network).
VLAN enables you to separate physical networks into logical subnetworks. Communication
is then only possible within the corresponding VLAN. Critical IP networks are isolated in this
way and communication is more secure.
Configure the VLAN manually as you usually would or with the support of a software assis-
tant.
If a device fails, you can replace it by means of Plug and Play. However, to do this, the
newly inserted device must be in the delivery state. The newly inserted device then
automatically adopts the entire configuration of the device it replaces.

TC EXTENDER...
16 / 110 PHOENIX CONTACT 108102_en_01
Possible VLAN system operation:
– Managed extenders only, configuration via web-based management
– Mixed operation of Unmanaged and Managed extenders, configuration via web-based
management
– Unmanaged extenders only, configuration via PSI-CONF software
Following configuration with PSI-CONF, you can use the VLAN functions in the Ether-
net network. However, the Unmanaged extenders are not visible with an IP address.
High availability thanks to RSTP redundancy
The Managed extenders support RSTP (Rapid Spanning Tree Protocol).
RSTP enables you to set up redundant ring or point-to-point topologies. The protocol auto-
matically disables duplicate or failed paths, thereby increasing network availability.
If a device fails, you can replace it by means of Plug and Play. However, to do this, the
newly inserted device must be in the delivery state. The newly inserted device then
automatically adopts the entire configuration of the device it replaces.
RSTP telegrams can also be transmitted in a network that only consists of Unmanaged ex-
tenders. However, you must operate the devices in hub mode.
• If the network only consists of Unmanaged extenders: deactivate switch mode in the
PSI-CONF software (IP Address Learning = active).
In mixed operation with Managed extenders, switch mode is automatically deactivated as
soon as you activate RSTP. However, to do this, all devices in the extender network must
already be connected to each other.
Greater transparency during diagnostics
The Managed extenders support SNMP (Simple Network Management Protocol).
For mixed operation of Unmanaged and Managed extenders, you can also read the status
of the Unmanaged extenders via SNMP (see 6.5.5 “Diagnostics via SNMP”).
Even more system events can be detected with the help of this function extension. You can
send alarm messages and diagnose system events via SNMP. This makes the communi-
cation network more transparent. In the event of malfunctions or tampering attempts, you
can initiate countermeasures quickly.
In conjunction with an MIB browser, the states of all Unmanaged extenders are also dis-
played via the IP address of the Managed extender. However, the Unmanaged extenders
do not have their own IP address in the network.
Along with the firmware update, it may be necessary under certain circumstances to also
update the MIB file in the MIB browser.
You will find the FW5.xx update package with the file EXTENDER_Private.MIB on our
website at phoenixontact.net/product/2702255.
