Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide
Cascade up to Eight Hubs to Build a Larger Network
As many as eight Model DS508, Model DS516, or Model DS524 hubs can be cascaded for up to a
maximum of 192 ports in a single repeater (or collision) domain. Any device connected to one of
the 192 ports at either 10 or 100 Mbps can connect through the network to any other device
attached to the cascade stack. The stack of eight hubs can consist of any combination of Model
DS508, Model DS516, and Model DS524 hubs daisy-chained together using the supplied cascade
cable. The LEDs in the following illustration appear as they would in an operational stack of hubs.
The cascade connectors on the Model DS508, Model DS516, and Model DS524 hubs use a shared
circuit. When power is supplied to one of the hubs in a stack, the Terminator LED in the top hub of
the stack and the Terminator LED and 10/100 Mbps Bridge LED in the bottom hub of the stack
will be on. If power is disconnected from the bottom hub in the stack, the hub above it takes over
the bridge function. Furthermore, the remaining hubs continue to operate if power is disconnected
from one hub in the stack.
