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.
