directed outside the segment. A BPM connecting this segment to the rest of the network, as shown in Figure 4.2e, will keep the local segment traffic isolated from the rest of the network, thus increasing the effective bandwidth on both the local segment and the rest of the network.

Local nodes with heavy local traffic, connected to front RJ-45 ports

3.Bridge Transparency: The BPMs are transparent to both the users and the application software.

4.LINK and Traffic Status: The Magnum BPM-TP and BPM-FST indicate link integrity with an LED. This LINK LED is normally lit. An unlit LINK LED indicates a broken cable or loss of power at some point in the segment. All BPMs have FWD-I and FWD-X status LEDs. The FWD-I LED flashes when packets are forwarded into the local segment. The FWD-X LED flashes when packets are forwarded out of the local segment.

5.Self-test Diagnostics: A Magnum BPM requires 15 seconds upon power- up before bridging services are available. During this time, the BPM performs an internal self-test.

4.3Power Requirements

Magnum 1000 Hubs are designed with internal auto-ranging AC power supply

units for efficiency and for simplicity of installation and operation. See Section 3.2, “Powering the Magnum 1000 Workgroup Hub” for detailed information on the AC power needed. See Section 1.1, “Technical Specifications: Power Supply (Internal)” for detailed information on the internal power supply units.

For optional 48VDC internal power supply information, see Appendix B.
