Connecting Tiers while the System is Powered Up

If necessary, you can connect a primary unit to a secondary unit while the system is
powered up. This technique can be used to isolate any problems with minimum
disruption to the system. When plugging a primary console switch into a secondary
unit, first connect the mouse and video cables, and then connect the keyboard cable.
This is important because the primary unit interprets the keyboard connection as the
secondary unit's power up. At this point, the primary unit sends initialization codes to
the secondary unit, triggering device configuration.
Refer to Chapter 4 for information on switching tiered systems.
