Figure A-5. Multiple Chassis Power Up Sequence
Important: While your system is operating, the following connect/disconnect rules
apply:
• If powering up too quickly or out of sequence, the PC or workstation may report
“ethernet connection timeout” and “socket timeout” errors.
• If you disconnect the primary master controller chassis, you break the
synchronization of the entire series of connected (RJ-45 Expansion In and Out
connected) chassis.
• If you disconnect a dependent chassis within a synchronized series, it breaks the
connection for itself and for all chassis following it (downstream) in the series.
• If you disconnect a master controller chassis in a stack, you automatically disconnect
all slave units connected (DB37) to it.
• If you disconnect a slave unit within a stack, the entire stack is disabled.
