Magnum 1000 Workgroup Hubs Installation and User Guide (04/02)

The family of Magnum 1000 Workgroup Hubs is comprised of Models 1008 (pronounced “ten oh-eight”), 1016 (“ten sixteen”) and 1024 (“ten twenty-four”). These models are equipped with 8, 16 or 24 front-mounted, shielded RJ-45 ports, respectively. Magnum 1000 Workgroup Hubs support full Ethernet segment lengths and operate in compliance with the IEEE 802.3 specification for repeater functionality to perform signal amplification, re-timing, and regeneration of preamble bits for each packet received. Consistent with IEEE 802.3 specifications, Magnum 1000 Hubs will detect collisions, generate jam signals, extend collision fragments, and automatically partition and re-connect individual ports.

For models with optional 48V DC power supply built in, see Appendix B.

2.2.1Magnum 1008 Workgroup Hub

The Magnum 1008 Workgroup Hub, shown in Figure 2.2.1a, has eight front- mounted, shielded RJ-45 ports and one rear-mounted AUI port. The left-most RJ-45

port (port 1) is equipped with a slide switch to allow cascading or an up-link without a crossover cable. Refer to section 3.3.1 for details about the up-link switch.

Status LEDs are located on the front panel of the Magnum 1008 for convenient monitoring of PWR, ACT (Activity) and LINK (per port). Magnum 1008s have an auto-ranging internal power supply, and are suitable for table-top-, wall-, or rack-mounting. Optional rack-mount brackets may be ordered, part number 1008-RMB.

Figure 2.2.1b shows the rear-mounted AUI port. This is the base or default configuration for the Magnum 1008. The basic AUI (standard female) port may be used for a direct connection with an AUI drop cable or for connection to any media type via an external mini-transceiver.

When using standard AUI cabling to connect to other Ethernet devices, it is important to consider the AUI segment length, including any cascading. Refer to Section 3.3.2 for detailed information on the AUI port, connector pins and standard cable length requirements.
