Procedure Code
FSPSP72 The network
sideband interface
controller (NSIC) has
detected that the
physical Ethernet
link is down.
IOHUB The failing
Symbolic CRU component is the
RIO/HSL NIC on
the IPL path.
Action
1. Using SRC word 6, determine which I/O module has been identified
as having a problem:
0x00000003
Blade center I/O slot 3
0x00000004
Blade center I/O slot 4
0x00000005
Blade center I/O slot 7
0x00000006
Blade center I/O slot 8
0x00000007
Blade center I/O slot 9
0x00000008
Blade center I/O slot 10
2. Verify that the I/O module installed in the blade center I/O slot
identified by word 6 of the SRC is marked compatible in the blade
center advanced management module (AMM) interface. Click System
Status > I/O Compatibility.
If the I/O module is marked as compatible, continue with the next
3.
step. If the I/O module is not marked as compatible, select an I/O
module slot that is compatible with the current blade configuration as
identified by the AMM. Select the I/O module for Ethernet traffic by
clicking Blade Tasks > Configuration > Interface Management > blade
> Management Network > Route Traffic Through. This ends the
procedure.
4. Reseat the I/O module identified in step 1. If the problem persists,
continue with the next step.
5. Reseat the blade system. If the problem persists, continue with the
next step.
6. Using SRC word 7, determine the FRU to replace:
0x00000001
CIOv form-factor expansion card
0x00000002
CFFh expansion card
0x00000003
Blade system
This ends the procedure.
Replace the system board and chassis assembly, as described in
"Replacing the FRU system-board and chassis assembly" on page 264.
