If your site uses only a few hubs and is not equipped with a mounting
rack, you may choose to place the LFH hub on a table or wiring closet
shelf. In this case, use the four self-adhesive rubber feet, which are
provided with the hub for cushioning purposes. Stick them at the four
corners of the bottom surface of the hub to cushion it against vibration.
2.5 Stacking LFH8-S/LFH16-S Hubs
You can stack up to six LFH8-S/LFH16-S hubs together using the
special connectors on the back panel. A single stack can contain a
mixture of 8-port and 16-port hubs. The maximum allowable any of
LFH8-S and LFH16-S hubs in a stack are 6 hubs.
When the LFH hubs are stacked together they are counted as a single
Fast Ethernet repeater, and the entire stack can be chained as a unit to
another Class II hub or hub stack.
To stack two LFH8-S/LFH16-S hubs together (see Figure 2-4):
1. Position the LFH hubs with one on top of the other.
2. Connect one end of the stacking cable to either one of the connectors
on the rear of the LFH hub. Make sure the cable snaps firmly onto
the connector.
3. Connect the other end of the stacking cable to either one of the
connectors on the other LFH hub.
