This section describes the LED indicators on the front panel of the IRT-401:

Figure 3-1. The IRT-401 Front Panel

From left to right, the front panel includes the following.

POWER: This is the power indicator. This LED will be green when power is supplied to your IRT-401.

LAN: These LED's indicate your Ethernet connection status. The LED's represent Ethernet ports 1 4, from left to right. A constant green light indicates corresponding port connection. A flashing green light indicates transmission.

ALM: This is the alarm indicator.

B1: This is the B1 ISDN line indicator. A green LED indicates that the port is in use.

B2: This is the B2 ISDN line indicator. A green LED indicates that the port is in use.

D: This is the data line indicator. A steady green LED indicates that your ISDN line is connected and functioning properly. A flashing green LED indicates that an ISDN connection is established, but that there is a problem with the connection configuration. If the LED is not lit, it means that there is no ISDN line connection.

  1. Router Diagram - Rear panel description

This section describes the components on the rear panel of the IRT-401:

Figure 3-2. The IRT-401 Rear Panel

Note: The ports and connectors for your ISDN line and your Ethernet connections are identical. Please be sure to clearly label each cable in order to avoid confusion. Connecting cables to the wrong ports may cause damage to your equipment.

From left to right, the rear panel includes the following.

Power: Connect the supplied power cable to this port.

TEL 1 and TEL 2: You can connect analog units, such as telephones or fax machines to these ports.

ISDN-S/T Interface: Connect your ISDN line to this port.

ISDN Terminator On / Off: If your NT-1 connects more than one ISDN equipment, you can turn on the ISDN terminator for matching impedance.

Console: Connect the supplied RS-232 cable to this connector.

LAN: Connect your 10Base-T Ethernet cables with RJ-45 connectors to these ports. The port numbers are 4 1, left to right.

  1. Cable Connections

This section provides step by step instructions for cable connections.

Figure 3-3. Connecting the all Cables

Installing the ISDN Cable

Note: Connect the ISDN line to the IRT-401 Router using the supplied RJ-45 cable. Connect one end to the ISDN NT-1 device and the other end to the RJ-45 on the IRT-401 rear panel labeled ISDN. (normally, the NT-1 is provided by the telephone company).

Connecting a PC to the IRT-401 Ethernet Port

  1. Use a straight-through 10Base-T Ethernet cable with RJ-45 connectors. Connect one end of the cable to one of the four ports on the IRT-401 labeled "Ethernet".
  2. Connect the other end of the cable to your PC's Ethernet port.

Note: If you have not installed and configured your PC's Ethernet card, please refer to chapter 4.

Connecting an IRT-401 Ethernet Port to Another Hub

Note: If the hub you wish to connect to the IRT-401 provides a MDI-II (Up-link) port, you can use a straight-through 10Base-T Ethernet cable with RJ-45 connectors. If the hub does not provide a MDI (Up-link) port, you must use a 10Base-T Ethernet crossover cable with RJ-45 connectors, you can find the cable in the pakage.

  1. Connect one end of the appropriate 10Base-T Ethernet cable to one of the four ports on the IRT-401 labeled "Ethernet".
  2. Connect the other end of the cable to the appropriate hub port.

Connecting Analog Equipment

Note: If you intend to connect analog devices such as modems, telephones or faxes to the IRT-401, use standard telephone RJ-11 cable and connect them to the RJ-11 ports on the IRT-401 rear panel labeled TEL 1 and TEL 2. These are general purpose ports and either can be used for any analog devices, phone, modem, fax machine. It is recommended that connect the frequently used analog device to TEL 1 first. It will reduce some data connection problem.

  1. Connect a RJ-11 cable or adapter into the IRT-401 port labeled "TEL 1" or "TEL 2.
  2. Connect the other end of the cable or adapter to your analog device.

Connecting the Power Cable

  1. Connect the provided power adapter cable to the IRT-401 connector labeled "Power".
  2. Connect the other end of the power adapter into a surge-protected 100 240 VAC wall outlet.

Note: When power is first provided to your IRT-401, the Power LED will come on and the router will conduct an internal diagnosis, during this process the ALM LED, B1, B2 and D channel lights will flash in a set sequence until diagnosis is complete. Reset and testing of the IRT-401 takes approximately 10 seconds.

Note: The IRT-401 has no power switch. As long as power is supplied at the wall outlet, the IRT-401 will be powered up.

Your IRT-401 is now successfully installed. If you do not have TCP/IP installed and set-up appropriately on your PC/Network to make use of your Internet Access, please continue with Chapter 4. TCP/IP Configuration. If you already have TCP/IP set up and installed on your PC and no changes are required, please continue with Chapter 5. Software Installation and Connection.
