This Board: Catalog Number: Provides a Link to:
Power Supply 1779ĆPH2 The Power Source for Your Module
MAC 1779ĆJMA/1779ĆJMAR The Data Highway II Network
Host 1779ĆJP5 The Data Highway Plus Network
The Power-Supply Board and MAC board are the same boards that you
use for the other Data Highway II modules (except the 1779-KP3). This
means that you do not need to keep a different type of spare
Power-Supply Board or MAC board for each interface on your network.
For more information on replacing the circuit boards inside your
1779-KP5, refer to the Data Highway II Replacement Boards Product
Data (Publication 1779-2.8).
Figure 6.2 shows the LED indicators on the front panel of the 1779-KP5
module. These indicators can help you in diagnosing problems with the
module’s installation and operation.
