described in steps 2 through 4.

uprights, as shown in Figure 2-3.
Figure 2-3 Installing a Hub Stack in a Rack
8 Repeat steps 2 through 7 when placing additional hubs in the stack.
A single hub stack can contain up to eight units (eight hubs, or seven hubs
and one Management Unit) and two Redundant Power Systems.
9 For each hub, plug one end of the power cord into the AC power connector
and the other end into a power source. (Refer to the section “Using the
Redundant Power System” for information on installing the Redundant
Power System.)
All the LEDs should light momentarily. Verify that the PWR (power) LED
remains ON, indicating that the hub is receiving power.
See Chapter 3 for information about connecting the stack to the network
and interpreting LEDs.
