Magnum 1000 Workgroup Hubs

Installation and User Guide (04/02)

Collisions: When carrier is detected simultaneously on multiple ports, a jam pattern is generated on each port to create a collision condition. When a collision signal from one port is detected, it generates a jam pattern to the other ports.

Partitioning and Re-Connection:Magnum 1000 Hubs will automatically partition any port where 32 consecutive collisions occur or after 6.5 milliseconds (msec) of continuous transmissions. Network integrity is checked every 800 msec and segment re-connection occurs after one 512-bit packet is transmitted without an error.

Fragment Extension: Magnum 1000 Hubs will automatically add bits to a received data packet of less than 96 bits (a "fragment") so that the minimum output packet to the other port is 96 bits long.

Preamble Regeneration: Magnum 1000 Hubs will add bits to the preamble so that the output packet contains a minimum of a 64-bit preamble.

Status LEDs: Each Magnum 1000 Workgroup Hub is designed with front panel LEDs to allow for quick visual assessment of the operational condition of the hub and the network. Each Magnum 1000 Hub is equipped with PWR, ACT, and LINK LEDs. Bonus Port RPMs are also equipped with status LEDs (see Section 2.4).

PWR LED: Illuminates GREEN to indicate proper operation of the internal power supply.

ACT LED: Illuminates GREEN to indicate “activity”, i.e., that the hub is processing network packets. Normally flashes to indicate data traffic.

LINK LEDs: Illuminates GREEN when connectivity is established between the hub and the attached device. Each RJ-45 port is represented by its own LINK LED. LINK should always be on during normal operation. LINK is OFF if connectivity or power is lost anywhere along the segment.
