Step 1542-7
The
Eserver
pSeries 630 Model 6C4 and Model 6E4 server may have up to two I/O subsystems
attached to its RIO ports. The following steps reduce the system I/O to only the I/O of the base system.
1. Turn off the system power.
2. At the base system, disconnect the cable connection at RIO-2 port 0 (U0.1-P1/Q2). Record all
connections.
3. At the base system, disconnect the cable connection at RIO-2 port 1 (U0.1-P1/Q3). Record all
connections.
4. Disconnect the power cables from the I/O subsystem(s) that were attached to the base system. All I/O
subsystems should now be physically disconnected from the base system.
Go to “Step 1542-8”.
Step 1542-8
The base system is running from the integrated I/O or from I/O attached to an adapter installed into one of
the integrated PCI slots.
1. Turn on the power to boot standalone diagnostics from CD.
2. If the Please define the System Console screen is displayed, follow directions to select the system
console.
3. Use the Display Configuration and Resource List to list all attached devices and adapters (refer to the
RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems
, order number SA38-0509,
if necessary).
4. Check that all attached devices and adapters are listed.
If the Please define the System Console screen did not display or all attached devices and adapters are
not listed, the problem is in the base system.
Did the Please define the System Console screen display and are all attached devices and adapters
listed?
NO
Go to “Step 1542-18” on page 135.
YES
Go to “Step 1542-17” on page 135.
Step 1542-9
For any I/O subsystem attached to the RIO-2 ports ot the base system:
If the I/O subsystem was recorded as
″
looped one
″
, are there any adapters in slots 1, 2, 3, 4, 5, 6,
or 7 (location codes U0.
dd
-P1-I1 through I7)?
NO
Go to “Step 1542-10”.
YES
Go to “Step 1542-11” on page 132.
Step 1542-10
For any I/O subsystem attached to the RIO-2 ports of the base:
If the I/O subsystem was recorded as
″
looped two
″
, are there any adapters in slots 1, 2, 3, 4, 5, 6,
or 7 (location codes U0.
dd
-P1-I1 through I7)?
NO
Go to “Step 1542-15” on page 134.
YES
