About Keysight L8990A-01H Switch with 89600 VSA Software

The 89600 VSA software supports the Keysight L8990A-01H switch as a standalone 32-port switch, or as an expansion switch which provides an additional 32 ports when connected to a Keysight L8990A-016 or L8990A-01A switch. In the expanded case, the L8990A-016 or L8990A-01A module is the primary switch (Ports 1-32) and the L8990A-01H module is used as an expansion switch (Ports 33-64). When used as a standalone switch, the L8990A-01H switch is not expandable.
