Issue
KVM0216A KVM Series Bus Communication Behavior
Product Line
- KVM Switches
- KVM0216A Enterprise Analog
- KVM0216A Enterprise Analog
Environment
- All installations
Cause
The next generation enterprise analog KVM boasts (2) local console users, and (16) ports. It also supports (1) or (2) bus cascading. When a local connection is simultaneously being used with a cascade connection, some pieces of information should be taken under advisement for expected (2) user operation.
Resolution
On the KVM0216A, the front DB-15 connection port is for use with an optional AP5717/AP5719 Rack LCD Console with the KVM-LCDMOUNT kit. This front port, the top cascade port (Cascade 2) and local console #2 are both using bus 2, while the bottom Cascade port (Cascade 1) and local console #1 are using bus 1.
