Adapter Status / LED States

Question
How do I check the state of the adapters in my IBM 2212?

Answer
LEDs on the front and rear of the IBM 2212 indicate the status of the adapter. (See Adapter Port LEDs and Additional Slot-Status LEDs.) The Maintenance Guide treats problem determination in more detail.

Adding an Adapter After Initial Configuration

Note:The compression/encryption adapter is a coprocessor (cpr) interface, not a net interface.

Question
How do I add an adapter after the IBM 2212 has been initially configured?

Answer
Install the adapter using the instructions accompanying the feature. Either use the Configuration Program and download the updated configuration to the IBM 2212, or follow these steps to configure adapters using the IBM 2212's OPCON command line interface (* prompt). (The section on FRU exchange in the IBM 2212 Service and Maintenance Manual describes the removal and replacement procedure.) Then:

  1. Access the OPCON command line interface (* prompt). See Accessing the OPCON Command Line Interface.

  2. Type talk 6 and press Enter to reach the Config> prompt. If the Config> prompt does not appear, press Enter again.

  3. Type add device type of device and press Enter.

    To see a list of device choices, type add device ? and press Enter.

    The following two steps do not apply when a dial-circuit device is being added.

  4. Enter the device slot number. If you add a PMC adapter or configure a Model 1xF or 1xH, you will not be prompted for a slot number.

  5. If you are adding an interface on a single-port adapter, go to step 6. Otherwise, continue with this step.

    Enter the port number. The range of port numbers supported depends on the multi-port adapter type.

  6. Make a note of the interface number to which this port is assigned and the net number. If you configure a WAN interface and wish to use a data-link type other than PPP, you must use the set data-link data-link type command to change the data-link type to any of the data-link protocols available on your IBM 2212 (frame relay, X.25, and SDLC for example).

  7. Enter at the Config> prompt net net number to access interface-unique configuration commands. Refer to the Access Integration Services Software User's Guide for a description of the supported interface commands.
    Note:This step does not apply to the compression/encryption adapter. At the Config> prompt, enter enable coprocessor to enable the compression/encryption adapter.

  8. Enter exit after configuring the interface.
    Note:This step does not apply to the compression/encryption adapter.

  9. Use the protocol command at the Config> prompt to configure protocols on the interface. Refer to Volume 1 and Volume 2 of the Access Integration Services Protocol Configuration and Monitoring Reference for a description of the supported commands for each protocol.

  10. Enter exit to get the Config> prompt.

  11. Repeat steps 3 through 10 if you have a multi-port adapter and you want to have more than one interface defined on the adapter.

  12. Enter write to save your changes.

  13. Press Ctrl-p to return to the OPCON (*) prompt.

  14. Enter restart at the OPCON (*) prompt.

Adding an Adapter at Initial Configuration

Note:The compression/encryption adapter is a coprocessor (cpr), not a net interface.

Question
How do I add an adapter to the software configuration when the IBM 2212 is being initially configured?

Answer
First, perform installation of the 2212 and install any additional adapters into the 2212. (The section on 2212 FRU Exchange in the IBM 2212 Service and Maintenance Manual describes the removal and replacement procedure.)

When the IBM 2212 is initially installed, it does not have any software configuration. The operating system will put you at the Config only> prompt.
Note:These steps create only the interface. Use the net command to configure characteristics unique to that interface (for example, T/R, Ethernet, PPP, FR, SDLC, X.25). (If the device is a coprocessor, then use the enable coprocessor command to enable the coprocessor.) You also need to use the protocol command to configure protocols on the interface.

If you configure a WAN interface and you want to use a data-link type other than PPP, use the set data-link data-link type command to change the data-link type to any of the data-link protocols available on your IBM 2212 (frame relay, X.25, and SDLC for example).

  1. Enter add device type of device

    To see a list of device choices, type add device ?.

    If you are adding a dial-circuit device, go to 4. Otherwise, continue with the following step.

  2. Enter the device slot number. If you add a PMC adapter or configure a Model 1xF or 1xH, you will not be prompted for a slot number.

  3. If you are adding an interface on a single-port adapter, go to step 4. Otherwise, continue with this step.

    Enter the port number. The range of port numbers supported depends on the multi-port adapter type.

  4. Make a note of the interface number to which this port is assigned and the net number.

  5. At the Config> prompt enter net net number to access interface-unique configuration commands. Refer to the Access Integration Services Software User's Guide for a description of the supported interface commands.
    Note:This step does not apply to the compression/encryption adapter. At the Config> prompt, enter enable coprocessor to enable the compression/encryption adapter.

  6. Enter exit after configuring the interface.
    Note:This step does not apply to the compression/encryption adapter.

  7. Use the protocol command to configure protocols on the interface. Refer to Volume 1 and Volume 2 of the Access Integration Services Protocol Configuration and Monitoring Reference for a description of the supported commands for each protocol.

  8. Repeat steps 1 through 4 if you have a multi-port adapter and you want to have more than one interface defined on that adapter.

  9. Enter write to save the changes.

  10. Restart the IBM 2212 to make the configuration changes active.

Disabling an Adapter Port
