is solved.
v
See Chapter 3, “Parts listing, System x3755 Type 8877 and 7163,” on page 25 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).

Beep code Description Action
One
continuous
beep Microprocessor error.
1. Reseat microprocessor/memory cards. See “Removing a
microprocessor/memory card” on page 51 and “Replacing
a microprocessor/memory card” on page 51.
2. (Trained service technician only) Remove microprocessor
2 and its VRM and restart the server. See “Removing a
microprocessor/memory card” on page 51 and “Replacing
a microprocessor/memory card” on page 51.
v
If no beep code occurs, microprocessor 2 might have
failed; replace the microprocessor. See “Removing a
microprocessor/memory card” on page 51 and
“Replacing a microprocessor/memory card” on page 51.
v If the beep code remains, remove microprocessor 1 and
install microprocessor 2 in the connector for
microprocessor 1; then, restart the server. If no beep
code occurs, microprocessor 1 might have failed;
replace the microprocessor. See “Removing a
microprocessor/memory card” on page 51 and
“Replacing a microprocessor/memory card” on page 51.
3. Replace the following components one at a time, in the
order shown, restarting the server each time:
a. Microprocessor/memory card 1, 2, 3; then, 4. See
“Removing a microprocessor/memory card” on page
51 and “Replacing a microprocessor/memory card” on
page 51.
b. (Trained service technician only) I/O board. See
“Removing the I/O board assembly” on page 68 and
“Replacing the I/O board assembly” on page 69.
