Daisy Chaining

MV 4105 units include a hub feature, which allows up to 4 units to be daisy chained (if each of the units is equipped with a hub). The unit at the end of the chain does not require a hub.

The built-in hub can be identified by looking at the back of the unit and at the Fibre Channel connections. The LEDs are located between the two Fibre Channel ports, as shown in Figure 4-5.
