+5 volt 1.7A maximum (maybe a problem with some systems !) consult the system manual.
+12 volt 40mA maximum
-12 volt 40mA maximum
35 BTU/hour Heat Output

Hardware Requirements

The following hardware is required to operate the IBM Wide Area Connector:

In order to operate, the WAC adapter card must be connected to DCE equipment with the cable that is shipped with the IBM Wide Area Connector package or with the EIB  accessory package.

Electrical Interface Board (EIB) Cable Connections

Each EIB is shipped with a cable specific to the interface it supports.

  Incorrectly matching a specific cable to an EIB link connection may cause damage to the WAC adapter card.

Installing the EIB

  1.  If the WAC adapter card has already been installed in the computer system,  you must remove the adapter to install an EIB.
  2.  Place the WAC adapter card on a flat surface
  3.  Orient the keyed EIB above the two rows sockets for the selected link.  Avoid touching the pins of the EIB. Match up the guide arrows  on the WAC adapter card 
  4.  Apply pressure evenly to the edges of the EIB until it has been inserted firmly on the WAC adapter card.
  5.  Affix a label identifying each link connector on the end plate next to the corresponding link connector.

  1.  Power Off the computer system
  2.  Disconnect the EIB-specific cable from the other equipment and install the diagnostic wrap plug.
  3.  Insert the Installation and Diagnostic Diskette  in the driskette drive.
  4.  Power ON the computer system, and follow the instructions displayed on the screen.

Error Messages
Error No. or Range    Action to Take
6501 to 6537    Replace the EIB, cable, and wrap plug for link A.
   There is an EIB, cable, or wrap  
   plug failure on link A  
6541 to 6577    Replace the EIB, cable, and wrap plug for link B.
   There is an EIB, cable, or wrap  
   plug failure on link B  
6578 to 6599    Take the following actions:
   The WAC adapter card is not 1. An EIB may not be installed properly
   working as expected.     Check to be sure the EIB is in place and the
      EIB-specific cable is connected securely.
  2. There may be a configuration error.
      Verify that the configuration parameters are correct.
  3. If the problem still exists after these actions are taken,
      replace the WAC adapter card.
  4. If the problem persists, run the diagnostics again
      for the computer system to identify the problem.

Software Requirements and Installation

The following software is required to install the OS/2 NDIS device driver for the WAC adapter card.

To install the device driver, follow these steps:
  1.  Start the OS/2 installation programm
  2.  Insert the Installation and Diagnostic Diskette  and follow the instructions  as they appear.
  3.  After you have configured the machine and installed the device driver, exit the installation  program and restart the operating system.

For more information, refer to the procedure for installing device drivers in IBM OS/2 LAN Server Network Administrator Reference  Volume 1
