Chassis Replacement

Table 16 Chassis replacement scenarios
Symptom
A FRU fails to seat properly, cannot be fully inserted,
or once inserted will not slide all the way into the slot.
The locking mechanism on a FRU is fully closed and
the FRU does not lock in place or locked down
properly.
A chassis with a defect that does not allow a FRU to
be installed.
An issue relating to the midplane
Recommended Action
Verify the following:
All the power supply units are working.
No slots are left open for more than two minutes. If you
might need to replace a module, leave the old module
in place until you have the replacement, or use a blank
cover to close the slot. Leaving a slot open negatively
affects the airflow and might cause the unit to
overhead.
The controller modules are properly seated in their
slots and that their latches are locked.
If the power supply module has a switch, ensure that
the switch is turned on.
Ensure that the power cables are firmly plugged into
both power supply and into an appropriate functional
electrical outlet.
Replace the power supply module.
If the power supply module has a switch, ensure that
the switch is turned on.
Ensure that the power cables are firmly plugged into
both power supply and into an appropriate electrical
outlet.
Replace the power supply module.
Replace the power supply module.
Action Required
Where a problem exists with the physical chassis itself,
replacement is necessary. Verify that a physical problem
does not exist with the specific FRU before replacing the
chassis. A mechanical issue of this type will not require
log evaluation.
A chassis must be replaced. To determine if the midplane
is the problem, collect and investigate the array logs. Also,
look for a 314 midplane FRU notification in array events
and a corresponding 247 related event.
