Action
1. Reseat the following components one at a time in
the order shown, restarting the server each time:
v (Trained service technician) Microprocessor 1
(see "Removing a microprocessor and heat
sink" on page 90 and "Installing a
microprocessor and heat sink" on page 94).
v (Trained service technician) Microprocessor 2,
if installed (see "Removing a microprocessor
and heat sink" on page 90 and "Installing a
microprocessor and heat sink" on page 94).
2. (Trained service technician) Complete the
following steps:
a. Remove microprocessor 2 and restart the
server (see "Removing a microprocessor and
heat sink" on page 90 and "Installing a
microprocessor and heat sink" on page 94).
b. If the problem remains, remove
microprocessor 1 and install microprocessor 2
in the connector for microprocessor 1; then,
restart the server (see "Removing a
microprocessor and heat sink" on page 90 and
"Installing a microprocessor and heat sink" on
page 94).
c. If the problem goes away, microprocessor 1
might have failed; replace the microprocessor
(see "Removing a microprocessor and heat
sink" on page 90 and "Installing a
microprocessor and heat sink" on page 94).
3. Replace the following components one at a time
in the order shown, restarting the server each
time:
v (Trained service technician) Microprocessor 1
(see "Removing a microprocessor and heat
sink" on page 90 and "Installing a
microprocessor and heat sink" on page 94).
v (Trained service technician) Microprocessor 2,
if installed (see "Removing a microprocessor
and heat sink" on page 90 and "Installing a
microprocessor and heat sink" on page 94).
v (Trained service technician) System board (see
"Removing the system-board assembly" on
page 97 and "Installing the system-board
assembly" on page 98).
