CHAPTER 3: Installation
Follow these steps when stacking:
1. Switch the Stack Enable switch of the bottom Stackable MiniHub to the
“OFF” position (left).
2. Switch all other units to the “ON” position (right).
3. Using the IRB ribbon cable, connect one end to either Inter-Repeater-
Bus connector (IRB1 or IRB2) of the bottom Stackable MiniHub.
Connect the other end of the cable to the corresponding IRB connector
of the top Stackable MiniHub (i.e, the IRB cable connects from IRB1 to
IRB1, or from IRB2 to IRB2).
4. If you will add more Stackable MiniHubs, connect another IRB cable
from the unused IRB connector of the existing stack’s top unit to the
corresponding IRB connector of the Stackable MiniHub you will add.
Make sure that the Stack Enable Switch of the added unit is set to the
“ON” position. You can stack up to five Stackable MiniHubs in this way.
5. Each unit of the stack must be powered by its own external power supply.
Make sure that the PWR LED of each unit is lit to verify “Power On.” If
one unit of the stack is powered off, the rest of the stack will still function
properly.
