Cabling and powering up the system 41
NOTE: Management modules are used only for information
management (asset tracking, for example). Disconnecting the
management module cabling does not affect system operation.
IMPORTANT: Improper cabling causes all the management link
connector LEDs on the management modules to flash.
Be sure the power configuration switches are set properly if you have a full-rack
solution with two pairs of mini bus bars. Refer to Power Configuration Switches
(on page
72 ) in this guide.
