Unit LEDs
The device has 4 LEDs marked as 1, 2, 3, 4 that are used to display the unit ID of
each unit (e.g. on Unit ID 1, LED 1 is ON and the other LEDs are OFF). To support unit
IDs greater than 4, the LED display is changed in accordance to the below
definition:
• Units 1-4: LEDs 1-4 are lit, respectively.
• Unit 5: LED 1 and 4 are lit.
• Unit 6: LED 2 and 4 are lit.
• Unit 7: LED 3 and 4 are lit.
• Unit 8: LED 1, 3, and 4 are lit.
Stack Topology
Types of Stack Topology
The units in a stack can be connected in one of the following types of topologies:
• Chain To p o l o g y —Each unit is connected to the neighboring unit, but there is
no cable connection between the first and last unit. See “Stack
Architecture (Chain Topology)” shows a chain topology.
• Ring Topology—Each unit is connected to the neighboring unit. The last unit
is connected to the first unit. The following shows a ring topology of an
eight-unit stack:
