5. Remove or disconnect the following devices (one at a time) until you find the
failure (reinstall, turn on and reconfigure the blade server each time):
v
I/O adapter
v
Drives
v
Memory modules (minimum requirement = two 256 MB DIMMs)
Note: Minimum operating requirements are:
a. System board
b. One microprocessor
c. Memory (with a minimum of two 256 MB DIMMs)
d. A functioning BladeCenter
6. Install and turn on the blade server. If the problem remains, suspect the
following FRUs in the order listed:
v DIMM
v System board
v Microprocessor
Notes:
1. If the problem goes away when you remove an I/O adapter from the system and
replacing that I/O adapter does not correct the problem, suspect the system
board.
2. If you suspect a networking problem and all the system tests pass, suspect a
network cabling problem external to the system.
