7299 Passive Hubs
Both of these low-cost models connect any 5250-type device to an AS/400,
System/38, or System/36 host over a distances of up to 100 m (326 ft). Because
these models do not require power, you can use them in wiring closets where no
power is available:
1PA This model, shown in Figure 1-3, supports one host port and up to
seven attached devices. This model can be used on a desktop or can
be mounted on a wall. The 1PA is a lower-priced equivalent of the IBM
5299 Terminal Multiconnector.
