To Remove the System Controller (CRU)
The system controller consists of a sub-enclosure that can be removed from the back
of the main system enclosure. The system controller contains the CPUs, memory, the
service processor, and optional PCI cards.
Caution – To prevent electrostatic discharge (ESD) damage to the components on
the system controller, connect a ground strap between yourself and the chassis
ground before proceeding.
1. Shut down the power from the front panel and then unplug both power supply
cords.
Caution – Although both power supplies should turn off then when you remove the
system controller, voltage could be present on the chassis connectors if either power
supply did not shut down as expected. Thus, you must pull the power cords from
the power supplies to avoid any risk from inadvertent contact with those connectors.
2. Remove the CMA from the X4500 as described in one of the following:
See one of the following docs depending on your CMA version:
