3.3 Connecting to the LAN
3.3.1 Connecting the IP-EXT Card
Refer to the following example to connect the IP-EXT card to the LAN.
When the IP-EXT card is connected to the LAN for the first time, you must assign IP addressing information
to the card. Refer to "4.1 Programming the IP-EXT Card" for instructions.
Note
• Use an Ethernet
straight cable with an RJ45 connector to connect the IP-EXT card to a switching hub.
The cable should be a 100BASE-TX CAT 5 (Category 5) or higher cable.
• Before connecting the IP-EXT card, attach a ferrite core (included with the card) to the cable.
• Make sure to set the port of the switching hub that connects to the IP-EXT card to operate under "Auto
Negotiation" mode.
• When using the VLAN feature on the network, make sure that the IP-EXT card is connected to a layer
2 switch that is IEEE 802.1Q compliant, and that is configured for VLANs. In addition, the port of the
switching hub to which the IP-EXT card is connected must be set to "Untagged". Consult your network
administrator for details.
• To use a KX-NT265, make sure that the Local Processor (LPR) software of the IP-EXT16 card is as
follows:
– PIPEXT Software Version 1.001 or later.
– PVOIPEX Software Version 1.011 or later.
• To use a KX-NT300 series IP-PT, make sure that the LPR software of the IP-EXT16 card is as follows:
– PIPEXT Software Version 2.000 or later.
– PVOIPEX Software Version 2.000 or later.
1. Wrap the cable once around the ferrite core, leaving 5 cm between the ferrite core and the connector.
2. Close the case of the ferrite core.
