Application Examples 2-3 2 Network Aggregation Plan When used in standalone mode, the MIL-SM4804G provides 52 parallel bridging ports (i.e., 52 distinct collision domains), which can be used to collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and thr...

Network Planning 2-4 2 Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This allows a Gigabit ...

Application Examples 2-5 2 Making VLAN Connections This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more...

Network Planning 2-6 2 Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. 2. Avoid using flow control on...
