Stacking
The hubs can be stacked as many as eight high, and all models
can be mixed in the same stack, in any order or combination.
Note: Although hubs can be stacked after being connected to
a power source, it is not recommended as a safe net-
working practice.
Before stacking the hubs, pay attention to the following guide-
lines:
• Be sure to have one stacking cable for each hub you want
to stack. This cable (order number SMC3300-CABLE) is not
provided with the hub, and must be ordered separately.
• If an NMM is installed in one of the hubs, be sure to set
the Unit ID switch on each hub in the stack to a unique
number. See your NMM User Guide for instructions about
setting the Unit ID switch.
To stack the hubs:
1. Locate the SCSI connectors labeled “A” and “B” on the rear
of each hub (refer to the the illustration on the next page).
2. Attach one end of the stacking cable to the SCSI connector
labeled “B” on the right hand side of the lower hub. Attach
the other end of the cable to the left connector labeled “A”
on the upper hub.
3. Repeat Step 2 until all the hubs (maximum eight) have been
stacked.
4. Go to “Connecting Power” at the end of this chapter.
