Section 7 - Technical Support

In the unlikely event you experience difficulty in the use of the product, or if it does not operate as described, we suggest you: (1) consult the Troubleshooting section of this guide and (2) consult with your dealer.

If you still cannot resolve the problem, call the MaxTech Service Center at (201) 586-8686 between 8:00 a.m. and 8:00 p.m. (EST Monday through Friday).

Appendix A - Daisy-Chain Cable Length

When daisy-chaining, the overall length between any two nodes should not ex- ceed the limits outlined in the IEEE 802.3u standard.

The maximum length from node to node = 367m - S(Repeater Equivalent Length

@CAT-5), or 367m - S(REL@5). The FHX-8100 has an inherent repeater delay of 80BT or 72 meters (REL@5). Taking a daisy-chain of two hubs for an example, the maximum cable length from node to node is: 367m - (2 x 72m) = 223m. If node A and B are attached to separate hubs in a two hub system, each using the maximum of 100 meters of cable to connect to their respective hub, then the cable between hubs is limited to 23 meters (i.e., 223m - (2 x 100m) = 23m).

To limit the number of hubs in a path (when daisy-chaining more than two hubs), link several hubs to one central hub. Use the above formula to determine maxi- mum cable lengths. Make sure there is only one path between any two stations on the network.
