CAUTION:
The CPU module is a field-replaceable unit (FRU). Replacement of the CPU
module can only be performed by certified IBM service personnel.
Replacing the CPU module consists of the following procedures:
v
“Removing the CPU module” on page 30
v “Moving the Data ONTAP software” on page 32
v
“Procedures for installing the CPU module” on page 31
Location of the CPU module and blank filler module
The CPU module is at the center position on the back of your N3700 storage
system. An active-active (clustered) N3700 storage system (2863–A20) has two
CPU modules (nodes), with Node A above Node B. On a non-active-active
(non-clustered) N3700 storage system (2863-A10), a blank filler module is in the top
position directly above the bottom CPU module. Both modules use the same cam
handle to remove and install the module.
Attention: Both modules must be in place with both bays plugged in during
operation to ensure proper airflow through the N3700 storage system.
CPU module contents
The CPU module contains the system motherboard, CPU, memory DIMM,
CompactFlash card (underside), battery pack, and other system components.
Reasons for removing the CPU module
There are several reasons for removing the CPU module:
v
Replacing a defective CPU module (IBM service representative only)
Note: If you are returning a defective CPU module, remove the SFP modules
from the defective module. Save them for reuse in the replacement CPU
module.
v Replacing the SDRAM DIMM
v Accessing the CompactFlash card
Backplane
connectors
CPU
Battery pack
Memory DIMM
