viii IBM System x3550 M4 Type 7914: Installation and Service Guide

Guidelines for trained service technicians

This section contains information for trained service technicians.

Inspecting for unsafe conditions

Use this information to help you identify potential unsafe conditions in an IBM product that you are working on.
Each IBM product, as it was designed and manufactured, has required safety items to protect users and service technicians from injury. The information in this section addresses only those items. Use good judgment to identify potential unsafe conditions that might be caused by non-IBM alterations or attachment of non-IBM features or optional devices that are not addressed in this section. If you identify an unsafe condition, you must determine how serious the hazard is and whether you must correct the problem before you work on the product.
Consider the following conditions and the safety hazards that they present: v Electrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
v Explosive hazards, such as a damaged CRT face or a bulging capacitor. v Mechanical hazards, such as loose or missing hardware.
To inspect the product for potential unsafe conditions, complete the following steps:
1. Make sure that the power is off and the power cords are disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and observe
any sharp edges.
3. Check the power cords: v Make sure that the third-wire ground connector is in good condition. Use a
meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.
v Make sure that the power cords are the correct type. v Make sure that the insulation is not frayed or worn.
4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the system for any obvious unsafe conditions, such as metal filings, contamination, water or other liquid, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Make sure that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.
®
Safety ix

Guidelines for servicing electrical equipment

Observe these guidelines when you service electrical equipment. v Check the area for electrical hazards such as moist floors, nongrounded power
extension cords, and missing safety grounds.
v Use only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live electrical current.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
v Do not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if it touches a live electrical circuit.
v Some rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical accident.
v Disconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
v Before you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that supplies power to the equipment and lock the wall box in the off position.
v Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
v If you have to work on equipment that has exposed electrical circuits, observe
the following precautions: – Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you work with powered-on electrical equipment, use only one hand.
Keep the other hand in your pocket or behind your back to avoid creating a complete circuit that could cause an electrical shock.
– When you use a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
v Use extreme care when you measure high voltages. v To ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of their normal operating locations.
v If an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that the following requirements are met.
v Each of the drive bays has a drive or a filler panel and electromagnetic
compatibility (EMC) shield installed in it.
v Each of the power-supply bays has a power supply or a filler installed in it. v If the server has redundant power, each of the power-supply bays has a power
supply installed in it.
v There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the server cover before you turn on the server. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components.
v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours. v You have replaced a hot-swap fan within 30 seconds of removal. v You have replaced a hot-swap drive within 2 minutes of removal. v You have replaced a failed hot-swap power supply within 2 minutes of removal. v You do not operate the server without the air baffle installed. Operating the
server without the air baffle might cause the microprocessor to overheat.
v Microprocessor socket 2 always contains either a socket cover or a
microprocessor and heat sink.
v You have installed the fourth and sixth fans when you installed the second
microprocessor option.

Working inside the server with the power on

Use this information when working inside the server with the power on.
Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.
You might have to have the server turned on while the cover is off, to look at light path diagnostics LEDs or replace hot swap components. Follow these guidelines when you work inside a server that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved
shirts before working inside the server; do not wear cuff links while you are working inside the server.
v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
v Remove items from your shirt pocket, such as pens and pencils, that could fall
into the server as you lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the server.
Chapter 2. Installing optional devices 35

Handling static-sensitive devices

Use this information to handle static-sensitive devices.
Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the following precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v The use of a grounding system is recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.
v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted
metal surface on the outside of the server for at least 2 seconds. This drains static electricity from the package and from your body.
v Remove the device from its package and install it directly into the server
without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.
v Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.

Installing a memory module

The following notes describe the types of DIMMs that the server supports and other information that you must consider when you install DIMMs.
v When you install or remove DIMMs, the server configuration information
changes. When you restart the server, the system displays a message that indicates that the memory configuration has changed.
v The server supports only industry-standard double-data-rate 3 (DDR3), 1066,
1333, 1600, or 1866 MHz, PC3-8500, PC3-10600, PC3-12800, or PC3-14900 registered or unbuffered, synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC). See http://www.ibm.com/systems/info/x86servers/serverproven/ compat/us/ for a list of supported memory modules for the server.
– The specifications of a DDR3 DIMM are on a label on the DIMM, in the
following format. ggggg eRxff PC3v-wwwwwm-aa-bb-ccd where:
Chapter 2. Installing optional devices 49
- ggggg is the total capacity of the DIMM (for example, 1 GB, 2 GB, or 4 GB)
- eR is the number of ranks 1R = single-rank 2R = dual-rank 4R = quad-rank
- xff is the device organization (bit width) x4 = x4 organization (4 DQ lines per SDRAM) x8 = x8 organization x16 = x16 organization
- v is the SDRAM and support component supply voltage (VDD)
v Blank = 1.5 V specified v L = 1.35 V specified, 1.5 V operable
Note: Values for these voltages are “specified” which means the device characteristics such as timing are supported at this voltage. Values are “operable” which means that the devices can be operated safely at this voltage. However, device characteristics such as timing may not be guaranteed. All devices must be “tolerant” of the highest DDR3 nominal voltage of 1.5 V, meaning that they may not operate at 1.5 V but may be powered at that voltage without damage to the devices.
- wwwww is the DIMM bandwidth, in MBps 6400 = 6.40 GBps (DDR3-800 SDRAMs, 8-byte primary data bus) 8500 = 8.53 GBps (DDR3-1066 SDRAMs, 8-byte primary data bus) 10600 = 10.66 GBps (DDR3-1333 SDRAMs, 8-byte primary data bus) 12800 = 12.80 GBps (DDR3-1600 SDRAMs, 8-byte primary data bus) 14900 = 14.93 GBps (DDR3-1866 SDRAMs, 8-byte primary data bus)
- m is the DIMM type E = Unbuffered DIMM (UDIMM) with ECC (x72-bit module data bus) L = Load Reduction DIMM (LRDIMM) R = Registered DIMM (RDIMM) U = Unbuffered DIMM with no ECC (x64-bit primary data bus)
- aa is the CAS latency, in clocks at maximum operating frequency
- bb is the JEDEC SPD Revision Encoding and Additions level
- cc is the reference design file for the design of the DIMM
- d is the revision number of the reference design of the DIMM
Note: To determine the type of a DIMM, see the label on the DIMM. The information on the label is in the format xxxxx nRxxx PC3v-xxxxxx-xx-xx-xxx. The numeral in the sixth numerical position indicates whether the DIMM is single-rank (n=1), dual-rank (n=2), or quad-rank (n=4).
v The following rules apply to DDR3 RDIMM speed as it relates to the number of
RDIMMs in a channel: – When you install 1 RDIMM per channel, the memory runs at 1866 MHz – When you install 2 RDIMMs per channel, the memory runs at 1600 MHz – When you install 3 RDIMMs per channel, the memory runs at 1066 MHz – All channels in a server run at the fastest common frequency – Do not install registered, unbuffered, and load reduction DIMMs in the same
server
50 IBM System x3550 M4 Type 7914: Installation and Service Guide
v The maximum memory speed is determined by the combination of the
microprocessor, DIMM speed, DIMM type, Operating Modes in UEFI settings, and the number of DIMMs installed in each channel.
v In two-DIMM-per-channel configuration, the server automatically operates with
a maximum memory speed of up to 1600 MHz when the following condition is met:
– Two 1.35 V single-rank, dual-ranl, or quad-rank UDIMMs, RDIMMs or
LRDIMMs are installed in the same channel. In the Setup utility, Memory
speed is set to Max performance and LV-DIMM power is set to Enhance performance mode. The 1.35 V UDIMMs, RDIMMs or LRDIMMs will
function at 1.5 V.
v The server supports a maximum of 16 dual-rank UDIMMs. The server supports
up to two UDIMMs per channel.
v The server supports a maximum of 24 single-rank, dual-rank, or 16 quad-rank
RDIMMs. The server does not support three quad-rank RDIMMs in the same channel.
v The following table shows an example of the maximum amount of memory that
you can install using ranked DIMMs:
Table 5. Maximum memory installation using ranked DIMMs
Number of DIMMs DIMM type DIMM size Total memory
16 Dual-rank UDIMM 4 GB 64 GB 24 Single-rank RDIMM 2 GB 48 GB 24 Single-rank RDIMM 4 GB 96 GB 24 Dual-rank RDIMM 4 GB 96 GB 24 Dual-rank RDIMM 8 GB 192 GB 24 Dual-rank RDIMM 16 GB 384 GB 16 Quad-rank RDIMM 8 GB 128 GB 24 Quad-rank LRDIMM 32 GB 768 GB
v The UDIMM option that is available for the server is 4 GB. The server supports
a minimum of 4 GB and a maximum of 64 GB of system memory using UDIMMs.
v The RDIMM options that are available for the server are 2 GB, 4 GB, 8 GB, and
16 GB. The server supports a minimum of 2 GB and a maximum of 384 GB of system memory using RDIMMs.
v The LRDIMM option that is available for the server is 32 GB. The server
supports a minimum of 32 GB and a maximum of 768 GB of system memory using LRDIMMs.
Note: The amount of usable memory is reduced depending on the system configuration. A certain amount of memory must be reserved for system resources. To view the total amount of installed memory and the amount of configured memory, run the Setup utility. For additional information, see “Configuring the server” on page 102.
v A minimum of one DIMM must be installed for each microprocessor. For
example, you must install a minimum of two DIMMs if the server has two microprocessors installed. However, to improve system performance, install a minimum of four DIMMs for each microprocessor.
Chapter 2. Installing optional devices 51
v DIMMs in the server must be the same type (RDIMM, UDIMM, or LRDIMM) to
ensure that the server will operate correctly.
v When you install one quad-rank DIMM in a channel, install it in the DIMM
connector furthest away from the microprocessor.
Notes:
1. You can install DIMMs for microprocessor 2 as soon as you install microprocessor 2; you do not have to wait until all of the DIMM slots for microprocessor 1 are filled.
2. DIMM slots 13-24 are reserved for microprocessor 2; thus, DIMM slots 13-24 are enabled when microprocessor 2 is installed.
The following illustration shows the location of the DIMM connectors on the system board.
Figure 35. DIMM connectors location

DIMM installation sequence

Depending on the server model, the server may come with a minimum of one 2 GB or 4 GB DIMM installed in slot 1. When you install additional DIMMs, install them in the order shown in the following table to optimize system performance.
In general, all three channels on the memory interface for each microprocessor can be populated in any order and have no matching requirements.

Memory mirrored channel

Memory mirrored channel mode replicates and stores data on two pairs of DIMMs within two channels simultaneously.
If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair of DIMMs. To enable memory mirrored channel through the Setup utility, select System Settings > Memory. For more information, see “Using the Setup utility” on page 106. When you use the memory mirrored channel feature, consider the following information:
v When you use memory mirrored channel, you must install a pair of DIMMs at a
time. The two DIMMs in each pair must be identical in size, type, and rank (single, dual, or quad), and organization, but not in speed. The channels run at the speed of the slowest DIMM in any of the channels.
v The maximum available memory is reduced to half of the installed memory
when memory mirrored channel is enabled. For example, if you install 64 GB of memory using RDIMMs, only 32 GB of addressable memory is available when you use memory mirrored channel.
v For UDIMMs, DIMM connectors 3, 6, 7, and 10 for microprocessor 1 and DIMM
connectors 15, 18, 19, and 22 for microprocessor 2 are not used in memory mirrored channel mode.
The following diagram lists the DIMM connectors on each memory channel.
