This PS/2 Server Interface Unit connects a server with PS/2 keyboard/mouse ports to a B064-Series NetDirector® KVM switch using Cat5e/6 cabling. Use of Cat5e/6 cables frees up space in server cabinets that would otherwise be filled by traditional, bulkier KVM cable kits. Compliant with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.Note: SIUs that were purchased prior to that of your KVM switch may require a firmware upgrade in order for them to work properly (see Maintenance under OSD Operation section in your B064-Series KVM Owner's Manual for details).
