4. Close the top and bottom ejectors simultaneously. Figure 2-2. ONcore Module Ejectors 5. The Reset LED should light ON briefly, and then turn OFF. 6. Fasten the spring-loaded screws on the front panel of the module to the hub using your fingers. Do not overtighten.
Installing the Module in a CELLplex 4000 Expansion Unit To install a 6412M-25-TP module in a CELLplex 4000 expansion unit, follow these steps: 1. Locate a vacant slot in the expansion unit. If the slot is filled with a blank panel, loosen the knurled screws on both sides of the cover and remove it from the front panel of the expansion unit.
2. Make sure that the slot to be used is in Isolated mode by entering the following command from the ATM console: SET MODULE slot ISOLATED where slot specifies the number of the slot to be used. For more information, see the CELLplex 4000 Installation and User's Guide .
4. Insert the 6412M-25-TP module into one of the free slots in the expansion unit as shown in Figure 2-5, matching the left and right board guides as you slide the module cleanly into place (by pressing evenly on the top and bottom of the faceplate). Figure 2-5.
Connecting ATM Devices After inserting the module, attach the cables to the ATM ports that will connect to ATM devices. Cabling Up The following sections provide instructions and guidelines for connecting ATM devices (such as switches, servers, personal computers, and workstations).
UTP/FTP/STP Cabling Information Table 2-2 details the accepted UTP/FTP/STP cables for the 25.6 Mbps ATM ports. Table 2-2. UTP/FTP/STP Cabling Details Cable Type Impedance Category Trunk Attenuation @ .
Cabling Distances Table 2-3 lists the maximum cabling distances for devices attached to the 25.6-Mbps ATM ports. Table 2-3. ATM Device Cabling Distances Cable Type Maximum Allowable Distance (meters) .
Connecting Devices to the ATM Ports You can connect devices to the ATM ports either through the building wiring or by a direct connection. Via Building Wiring To connect an ATM device via building wiring, follow the steps listed below. Note: This procedure begins with the cabling of the ATM device (such as a 25.
Direct Cabling To cable an ATM device directly to the 6412M-25-TP module: 1 Look at the cabling chart, which your network planner provided, to determine how the ONcore hub or CELLplex 4000 should be connected to the network. 2 Connect the cables between the 6412M-25-TP module and other devices as indicated by the connections in the cabling chart.
Cables, Pins and Connectors Each of the ATM ports on the 6412M-25-TP module connects to other ATM devices using an 8-pin female RJ-45 connector. The sections below describe the male RJ-45 plug and the twisted-pair cables that attach to this connector.
Twisted-Pair Cable Figure 2-7 on page 2-16 below shows the pin-outs for the straight-through cable required for connecting ATM Forum compliant devices via UNI interface to the ports on the 6412M-25-TP module. Note: Pins 3, 4, 5, and 6 are not used and are grounded on the chassis.

Chapter 3. Configuration After installing the 6412M-25-TP module and attaching media cables to ATM devices, you must enter configuration commands from the ATM console to: Configure the ports parameters. Connect the module to the network. Enable the ports.
To set individual port parameters, enter the following command at the ATM console prompt. The parameters may be entered in any order. SET PORT slot.port mode type flow_control ilmi slot Slot number of the 6412M-25-TP module. port ATM port number. mode enable or disable .
Example The following example configures port 2 of the 6412M-25-TP module installed in slot 1. ONcoreATM > set port 1.2 uni [ ENTER ] ONcoreATM > Port set. ONcoreATM > show port 1.2 verbose [ ENTER ] Type Mode Status ------------------------------------------------------------------------------- 1.
For example, to display configuration information about the 6412M-25-TP module in slot 2, you would enter the following command: ONcoreATM> show module 2 verbose Slot Install Connect Operation Gene.
Port Information To display status information about the ports of an 6412M-25-TP module, use the SHOW PORT command. The following example shows how to display detailed information about port 1 of the 6412M-25-TP module in slot 1: ONcoreATM > show port 1.
Connecting the Module to the Network When you install an 6412M-25-TP module, it is by default set to Isolated mode and all of its ports are disabled. When a module is isolated, no network activity takes place on it and it cannot be accessed by the network.
Verifying Module Operation After configuring and saving 6412M-25-TP module and port settings, you can verify that the module is operating correctly by viewing the LEDs on the front panel: The Port Status light should be lit (Green if no traffic, Yellow when traffic is present) The Module Reset LED should be off.
Front Panel ATM connections are made through the 6412M-25-TP module by means of the ports on its front panel and its backplane interfaces. The front panel is shown in Figure 3-1 on page 3-10. The meaning of each LED is shown in Table 3-1. By pressing the Module Reset button, you interrupt and reset the operation of the 6412M-25-TP module.
See Chapter 4, “Troubleshooting” on page 4-1 if: A Port Status LED does not light or is blinking. The Reset LED is ON or is blinking. The Wrong Slot LED is ON. Table 3-1 (Page 2 of 2). Meaning of the Front Panel LEDs LED Name Color State Meaning Wrong Slot Yellow OFF Normal operation.

Chapter 4. Troubleshooting This chapter describes how to diagnose and solve problems that may arise with the operation of an 6412M-25-TP module. These problems are signaled by the following conditions: The Port Status LED of a port does not light green, or is blinking, when idle (connected and enabled but no traffic).
Port Status LED Does Not Light Green or Is Blinking When Idle During normal operation, the Port Status LED of an 6412M-25-TP module should light GREEN if the port is enabled and a connection present.
Table 4-1 (Page 1 of 2). Problem Determination Using Port Status LEDs Status LED Port Status Possible Cause Corrective Action OFF Disabled Port is disabled. Enable port. Enabled 6412M-25-TP module is not powered ON. 1) Check that the ONcore or CELLplex 4000 is connected to a power supply.
Table 4-1 (Page 2 of 2). Problem Determination Using Port Status LEDs Status LED Port Status Possible Cause Corrective Action Blinking Enabled No connector is attached to the port, or there is no device at the end of the connection. Attach a connector to the port, or ensure that there is a device at the end of the connection.
Port Status LED Does Not Light Yellow During Traffic If during continous traffic the Status LED of a port does not light YELLOW, refer to Table 4-2 on page 4-6 to diagnose and solve the problem.
Table 4-2. Problem Determination Using Port Status LEDs during Traffic Status LED Possible Cause Corrective Action OFF Port is disabled. Enter the SHOW PORT command at the ATM console to see if port is enabled.
When the Reset LED Is ON or Starts Blinking When the Reset LED of an 6412M-25-TP module is ON or starts blinking, the module has entered into an error condition. Table 4-3 describes the possible problems that may occur and the corrective action to take for each problem.
When the Wrong Slot LED Is ON (ONcore only) When the Wrong Slot LED of an 6412M-25-TP module is ON, the module is not installed in the correct slot. Remove the module from the hub and re-insert it into any vacant slot in positions 1 to 8 (or 12 to 17 in 6017C-AC model).
Determining the Failing Component Using a Wrap Test In the troubleshooting procedures in this chapter, you are sometimes instructed to perform a wrap test in order to determine the failing component that caused the problem. To run a wrap test: 1. Enter the SET PORT slot.
Replacing 6412M-25-TP Modules The troubleshooting procedures in this chapter sometimes instruct you to replace a failing 6412M-25-TP module. To do so, follow these steps: 1. Enter SET MODULE slot ISOLATED where slot is the slot number of the failed module.
