4 Hints, Tips, and Frequently Asked Questions for the xSeries 440:Quick Reference
Cabling For additional cabling information, see “Cabling” on page 18.
Ensure retention of main power cables
Scalability cables difficult to install and remove
Description: When sliding the server in and out of the rack enclosure, the power cords might
loosen or detach from the server.
Solution: In addition to the cable strap used to secure the power cords to the hinge
plate (as stated in step 13 of the Rack Installation Instructions), install a cable strap
around the power cords and the cable-management arm, directly behind the hinge
that connects the arm to the hinge plate.
For more information: See Tip H76202 at http://www.ibm.com/pc/support/.
Description: The EMC shield (scalability bracket) on some xSeries 440 servers is not
recessed enough, and this makes it is very difficult to install and remove the scalability cables.
(For additional information about connecting the scalability cables, see “Cabling” on page 18.)
Solution: Obtain the replacement EMC shield. For assistance in obtaining the replacement
EMC shield:
• In the United States and Canada, call 1-800-772-2227 and ask for FRU part number
24P1240.
• In all other countries, go to http://www.ibm.com/planetwide/ to view a list of the most
current support telephone numbers; then, call the support line for your country or region
and ask for FRU part number 24P1240.
A new Miscellaneous Parts Kit that includes the replacement EMC shield (24P1240) will be
available in September, 2002.
For more information: See Tip H081720 at http://www.ibm.com/pc/support/.

Chapter 2. Hints and tips 5
Covers
Top-cover latch difficult to use on servers manufactured prior to 6/14/02
Description: The top-cover latch on some xSeries 440 servers manufactured prior to June
14, 2002 are difficult to operate. Systems manufactured after 6/14/2002 are not affected.
Note: The system chassis is marked with a date on the front left side.
Solution: Replace the cover latch. Order FRU part number 24P1289 for systems that have a
chassis label dated 6/14/2002 or before.
Use a flat-blade screwdriver or similar tool to remove the existing top-cover latch; then, snap
the replacement latch into place.

6 Hints, Tips, and Frequently Asked Questions for the xSeries 440:Quick Reference
Error log messages
Machine Check Architecture (MCA) with BIOS 1.02 or earlier
Ethernet messages
PRO/1000 XT Gigabit Ethernet: NMI error or dropped connection
Description: The microprocessors or SMP Expansion Modules are disabled when the
following MCA message appears in the error log of xSeries 440 servers running BIOS 1.02 or
earlier:
Error Code: 00151200 MCA: Unrecoverable Error Detected
Error Code:
Error Data: ProcID=08
Error Data:
Entry Number: 5
Solution: Download and install the xSeries 440 BIOS Update version 1.03 or later. You can
obtain the BIOS update at http://www.ibm.com/pc/qtechinfo/MIGR-42518.html/.
MCA is still a valid error message that can appear if a problem occurs. BIOS Update version
1.03 corrects the specific problem described above.
For more information: See Tip H176213 at http://www.ibm.com/pc/support/.
Description: Nonmaskable Interrupt (NMI) errors or dropped network connections can occur
if an Intel®PRO/1000 XT server adapter is installed in any of the 133 MHz slots in the server.
Note: For additional information about NMI error messages, see “Nonmaskable Interrupts
(NMI)” on page 22.
Known configuration: An IBM xSeries 440, type 8687 server (any model) with an Intel
PRO/1000 XT server adapter (option part number 22P6801, FRU part number 22P6809)
installed. An IBM RXE-100 Remote Expansion Enclosure, Type 8684, model 1RZ is attached
to the server.
Solution: Move the PRO/1000 XT adapter to a slower PCI slot. The xSeries 440 server sup-
ports six hot-plug 64-bit adapters in the expansion slots as follows:
Slot 1 66 MHz
Slot 2 66 MHz
Slot 3 100 MHz (133 MHz if Slot 4 is empty)
Slot 4 100 MHZ (133 MHz if Slot 3 is empty)
Slot 5 133 MHZ
Slot 6 133 MHz
For more information: See Tip H033438 at http://www.ibm.com/pc/support/.

Chapter 2. Hints and tips 7
Linux For additional information, see “Network operating systems” on page 21.
Linux operating-system clock drifts from the system real-time clock
(RTC)
USB keyboard and trackpoint mouse with SuSe Linux, version 8.0
Description: The Linux operating-system clock drifts or loses time when the service
processor is in a Remote Console session. The longer the Remote Console session, the
more the clock is skewed. This occurs with any supported version of the Linux operating
system.
Linux tics their operating-system clock roughly 100 times a second. If you are in a Remote
Console session during this same time frame, there are anywhere from 8 to 60 SMI (System
Management Interrupts) events occurring (depending on the activity). Due to these events,
some of the Linux timer tics are getting missed and thus the time shift.
Notes:
1. The system real-time clock is operating correctly; only the Linux operating-system clock
is losing time.
2. SMI are used to do the remote video updates through the service processor.
Workaround: Synchronize the Linux operating-system clock to the system RTC.
There are two options:
• Periodically restart the server. This will cause the Linux operating-system clock to sync up
with the system RTC.
• Use a time server on the network to periodically synchronize the Linux operating-system
clock to the time server.
For more information: See Tip H176196 at http://www.ibm.com/pc/support/.
Description: The USB keyboard andTrackpoint mouse work fine duringinstallation; however,
after reboot one of them might cease to function properly.
Note: Unplugging and re plugging the device (into the rear USB slots) might fix the problem.
Known configuration affected: An xSeries 440 server with the following installed:
• A Trackpoint USB Space Saver Keyboard, option part number 22P5150, replacement
part number (FRU) 24P0340
• The usb-uhci device driver for the VIA USB UHCI controller
• SuSe Linux, version 8.0
This behavior occurs due to new timing code for USB that was introduced into the kernel. This
issue is being investigated and should be resolved in the third quarter of 2002.
Workaround: Use a PS/2®keyboard.
For more information: See Tip H176029 at http://www.ibm.com/pc/support/.

14 Hints, Tips, and Frequently Asked Questions for the xSeries 440:Quick Reference
Installing an SMP Expansion Module
Attention: The installation and removal of the SMP Expansion Module is a two-handed
operation. Always use two hands when installing or removing an SMP Expansion Module.
Description: You can damage capacitors on the centerplane if you are not careful when you
install or remove an SMP Expansion Module (sometimes referred to as a CEC).
Solution: To help avoid problems, use the following procedure when installing or removing
an SMP Expansion Module:
1. Hold the SMP Expansion Module level in a horizontal plane by using the blue handle with
one hand and the recessed finger hold with the other hand.
Note: Future SMP Expansion modules will have the IBM Blue touchpoint color around
the finger hold.
2. With the SMP Expansion Module slightly tilted down into the system, align the front edge
of the SMP Expansion Module against the side of the top cross member of the chassis;
then, align the side wall of the SMP Expansion Module against the inside wall of the
chassis.
3. While keeping the SMP Expansion Module in a horizontal plane and still maintaining the
tilted alignment described in Step 2, carefully lower the SMP Expansion Module into the
chassis; then, gently slide the SMP Expansion Module into the mating connectors.
4. Simultaneously move the locking levers into the locked position.
5. Reinstall the EMC shield on the rear of the server; then, tighten the blue thumbscrew.
6. Reinstall the shipping/retention bracket or brackets.
Note: If only one SMP Expansion Module is installed, install the SMP baffle.
7. Close the cover; then, connect the external cables.
Note: If two SMP Expansion Modules are installed, be sure to connect the scalability
cables. For more information, see “How should I connect the SMP Expansion
cables (scalability cables) when I have two SMP Expansion Modules installed?”
