NCL1100 Installation & Operation Manual 1 Introduction This manual explains how to install an NCL1100 Network Communications Link system and operate it in an Ethernet or Token Ring environment, either under IEEE 802.3 or Ethernet II specifications. Ethernet II is not supported at this time for the Token Ring to Ethernet bridge, only Token Ring to IEEE 802.2/802.3 is supported. WaveRider Communications can only provide support for hardware and software that are sold with the NCL1100.
NCL1100 Installation & Operation Manual The NCL1100 unit determines its environment at power-up, and builds its own address tables based on the observed activity on the LAN segment to which it is attached. The system is designed this way to minimize the required set-up and user administration. 2 Installation Although the NCL1100 Network Communications Link is as user-friendly as possible, keep in mind the design considerations.

NCL1100 Installation & Operation Manual 110/220 VAC 10BASE-T, AUI, or BNC Ports CPU card RF card 2-3 LAN Connection The port for the network interface card includes three interfaces: an AUI connector, a 10BASE-T connector, and a BNC or 10BASE-2 connector. You can only use one port at a time and this is determined automatically during the boot or start-up process; therefore, you must connect the LAN before you power up the bridge. Do not power up the NCL1100 system until you make all the connections.
NCL1100 Installation & Operation Manual 2-5 Error Messages When there are problems, the system displays these error messages: • Unable to open file The InterBuilding Link.CFG Cause: The configuration file for IBL.EXE was not present in the current directory when you started the NCL1100, or the file does not exist. Cure: Type dir and the file name at the C> prompt to ensure that the IBL.EXE and Link.CFG files are present. If the files are not present, use the WaveRider Communications website at www.
NCL1100 Installation & Operation Manual Figure 4 is a diagnostic screen that shows RF packets outgoing. Note that since only one bridge is transmitting, the outgoing utilization is 100%. On the 11 Mb/s, however, the maximum utilization is 84%, with the packet size set at 1514 (T 1514 then ). Figure 3: Screen, Normal Mode Figure 4: Screen, RF Packets Outgoing As well as the normal display screen, the NCL1100 has a diagnostic utility included.
NCL1100 Installation & Operation Manual show the packets received and sent since the last screen update. The system updates the screen approximately once/second. Outgoing packets are shown even if the RF link, between the local and remote RF sites, is not working. If the RF link is not working, however, no incoming RF packets are shown at the remote RF site even if the local RF site is placed in a test mode so that the local site generates outgoing RF packets.
NCL1100 Installation & Operation Manual 4. If the incoming RF utilization is less than 44%, then the RF link portion of the system is suspect. Focus your trouble-shooting on the coaxial cable, antenna, or interference. 5. If the RF link is not working, the coaxial cable is connected properly, and the antennae are in unobstructed alignment with each other, then you many need a spectrum analyzer (refer to Figure 8) to pinpoint interfering frequencies and take corrective action.
NCL1100 Installation & Operation Manual 4 SNMP Installation This section describes how to configure and use SNMP (simple network management protocol) on the wireless link. The wireless bridge includes an SNMP agent that collects valuable statistical and configuration information about the network interface card inside your wireless link. Network administrators analyze this information to keep their networks operating at peak efficiency.
NCL1100 Installation & Operation Manual 1990/07/21 • † In a TCP/IP network, these are IP addresses of network management stations to which to send traps (alerts) if an alarm occurs. In an IPX network, these are IPX network addresses (e.g., smcDosWsTrapDstAdr.1) of the network management stations where traps are sent. Traps can be sent to a maximum of three management stations (Adr.1, Adr.2, and Adr.3).
