Magnum 8000X Mixed-Media Fiber Hubs

Installation and User Guide (05/ 02)

 

 

 

SPM-FDSSC’s can be used together on each end of a fiber segment to get the maximum distance of 15km of single-mode fiber optic cable in a Fast Ethernet network. For an SPM-FDSSC used to connect into a separate collision domain, the cable distances and hop-counts allowable would have to be calculated taking into account all the devices’ Path Delay Values (PDVs) that are part of that domain.

An SPM operating at 100Mbps has a PDV of 50 BT, i.e., the same PDV as a DTE or NIC card in a Fast Ethernet collision domain.

2.5.4Magnum SPM-TTX

The Magnum SPM-TTX is a 10 Mbps or 100Mbps device equipped with one RJ-45 port which supports either 10BASE-T and 100BASE-TX. The 10/100 speed selection is done with a manual switch on

the unit to prevent ambiguity where it may be used with other devices such as NICs that are auto-sensing.

The SPM-TTX filters and forwards packets, maintains its address tables, and segments the network when used as a 10BASE-T or a 100BASE-TX switch port. See Sections 2.5 and

2.5.1for a general description of an SPM. The SPM-TTX

includes an up-link switch to allow for connection to either user nodes or for cascaded up-link connections to other hubs. The attached devices may be either 10 Mb or 100Mbps.
