Director Network Module
Director Network Module (DNM) is a pluggable, eld upgradeable Director
module with 12 network ports. Depending on the DNM model, each module
provides 6 in-line links or 12 Span ports, supporting Gigabit SX/LX/ZX Fiber
or 10/100/1000 Copper media.
Director supports up to 2 modules. Each Director chassis has two DNM slots
that may be populated with di erent models of DNM.
Virtual Zero Delay (VZD)
VZD is a new, patent-pending technology from Net Optics designed to
improve network reliability when using copper taps.
Net Optics’ new DNM-101 Module’s innovative Virtual Zero Delay circuitry
guarantees that Director™ and Director Pro™ in-line copper connections will
never lose their links when power goes o for whatever reason—such as
power failures or during planned power up and power down events. In the
past, link renegotiation has been a major challenge for copper taps, costing
precious seconds or minutes of link downtime when Tap power transitions.
DNM-101 VZD eliminates those lengthy renegotiation cycles by preserving
the link state through power transitions, as if no break existed.
