BUS EXTENSION
The IEN 2000, IEN 3000, IEN 4000 and IEN 5000 chassis contain two and sixteen slots
respectively. When your site requirements exceed the number of slots provided by a single
chassis, you use the bus extension to combine several chassis (up to 240 ports) into a single
IEN logical node. Bus connected chassis appear to IENView as a single node with many
ports.
There are two types of bus extensions supported by the IEN 2000, IEN 3000, IEN 4000 and
IEN 5000 chassis: standard and high-speed.
Note: The IEN 1000 chassis does not support bus extension.
