1. Partitioning and Re connection Personal Hubs will automatically partition a port when 32 consecutive collisions occur or after 6 5 ms of continuous transmission Network integrity is checked every 800 ms and segment re connection occurs after one 512 bit packet is transmitted without an error Preamble Regeneration Personal Hubs add bits to the preamble so that the output packet contains a minimum 64 bit preamble per the Ethernet standard 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 other ports 15 Magnum Personal Hubs Installation and User Guide 09 01 Fragment Extension Personal Hubs will automatically add bits to a received data packet of less than 96 bits a fragment so that the repeated packet is 96 bits long 16 Magnum Personal Hubs Installation and User Guide 09 01 5 0 TROUBLESHOOTING All Magnum Ethernet products are designed to provide reliability and consistently high performance in all network environments The installation of Personal Hubs is a simple procedure see Section 3 0 INSTALLATION operation is very simple and is described in Section 4 0 OPERATION Should problems develop during installation or operation this section should help to locate identify and correct such problems Please follow the suggestions listed below cont2. 1 0lbs 455gr Cooling method Convection Agency Approvals 115v 60 Hz Power Supply is UL Listed CSA certified 230v 50 Hz Power Supply is same also GS approved Emissions Meets FCC Part 15 Class A and B VDE Class B Warranty Three years see also Appendix A Made in USA Magnum Personal Hubs Installation and User Guide 09 01 1 2 Ordering Information Magnum Personal Hubs MODEL DESCRIPTION Magnum H40A d_ Personal Hub with four standard RJ 45 ports one with up link switch plus one AUI port external 115 vac 60 Hz power supply Magnum H40A i Same as H40A d but with external 230 vac 50 Hz power supply MagnumH50 d Personal Hub with four standard RJ 45 ports plus one switched RJ 45 up link port external 115 vac 60 Hz power supply Magnum H50 i Same as H50 d except with external 230 vac 50 Hz power supply Magnum H80A d_ Personal Hub with eight standard RJ 45 ports one with up link switch plus one AUI port external 115 vac 60 Hz power supply Magnum H80A i Same as H80A d but with external 230 vac 50 Hz power supply Magnum H90 d Personal Hub with eight standard RJ 45 ports plus one switched RJ 45 up link port external 115 vac 60 Hz power supply Magnum H90 i Same as H90 d except with external 230 vac 50 Hz power supply GarrettCom Inc reserves the right to change specifications performance characteristics and or model offerings without notice Magnum Personal Hubs Installation and U
