Magnum 8000X Mixed-Media Fiber Hubs

Installation and User Guide (05/ 02)

results in more available network bandwidth on both sides and a throughput increase on for all users on both domains.

3. Software Transparency

The Magnum 8000X Dual-Speed Hubs need no software set-up and are transparent to system and application software, including network management software.

4.3Auto-negotiation and speed-sensing

The PM-RJ45 and PM-RJ45U ports independently support auto-negotiation for shared 10BASE-T and 100BASE-TX modes. When the ‘S’ LED is flashing on a port, it means that the hub is sending out auto-negotiation pulses on that port. When a LINK connection is initially made, the other device should respond and both sides should agree on the speed capability being signaled. The device connected, depending on what it is, will either signal that it is capable of 10 Mbps or 100Mbps speeds. Silence means the port defaults to 10 Mbps.

When the ‘S’ LED is steady ON, the port has auto-negotiated for 100Mbps operation and is running at 100Mbps. When it is steady OFF, it is at 10 Mbps. If a 8000X copper port is connected to a non-negotiating device, it will default to 10 Mbps speed. Since Magnum 8000Xs are hubs, front ports always operate in half-duplex mode.

General information -

Auto-negotiation per-port for dual-speed hubs occurs when:

the devices at both ends of the cable are capable of operation at either 10Mb or 100Mb speed, and can send/receive auto-negotiation pulses, and . . .

--when the second of the two connected devices is powered up*, i.e., when LINK is established for a port, or

--when LINK is re-established on a port after being lost temporarily.

NOTE – some NIC cards only auto-negotiate when the computer system that they are in is powered up. These are exceptions to the “negotiate at LINK – enabled” rule, but may be occasionally encountered.

4.4Chassis LEDs

The Magnum 8000X is equipped with six LEDs located on the front of the chassis unit (see Figure 2.3b). These LEDs are Power (PWR), Bridge(BRD), Collision (COL) and Activity (ACT) for 10 and 100Mbps speed. They are used to provide visual indication about the operational condition and traffic activity of the 8000X unit and its associated PM cards.
