Guidelines for servicing electrical equipment
Observe these guidelines when servicing electrical equipment.
vCheck the area for electrical hazards such as moist floors, nongrounded power
extension cords, and missing safety grounds.
vUse 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.
vRegularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
vDo 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.
vSome rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
vDo not work alone under hazardous conditions or near equipment that has
hazardous voltages.
vLocate 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.
vDisconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
vBefore 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.
vNever assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
vIf 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.
vi BladeCenter S Type 7779/8886: Problem Determination and Service Guide

– When you are working 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 using 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.
vUse extreme care when measuring high voltages.
vTo 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.
vIf an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.
Inspecting for unsafe conditions
Use this information to help you identify potential unsafe conditions in an IBM®
product that you are working on.
About this task
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

xii BladeCenter S Type 7779/8886: Problem Determination and Service Guide

Chapter 1. Introduction
The BladeCenter®S Type 8886 is a high-density, high-performance rack-mounted
server system. It supports up to six blade servers that can share common resources,
such as power, cooling, management, and I/O resources within a single
BladeCenter S chassis. In addition, it provides support for up to twelve 3.5-inch,
hot-swappable SAS or SATA hard disk drives.
The BladeCenter S system provides the following features:
vIBM Enterprise X-Architecture®Technology
IBM Enterprise X-Architecture Technology leverages proven innovative IBM
technologies to build powerful, scalable, and reliable blade servers. It provides
features such as IBM Predictive Failure Analysis (PFA) and real-time diagnostics.
vServer expansion capabilities
You can add up to six blade servers to the BladeCenter S chassis. Some blade
servers have connectors for additional optional devices that you can use to add
capabilities to the blade server. For example, you can connect either a storage
expansion unit or a PCI expansion unit to a blade server. Alternatively, you can
add optional I/O expansion cards to add network interfaces or storage through
I/O modules. SAS expansion cards provide access through SAS connectivity
modules or SAS RAID controller modules that are installed in I/O bays 3 and 4
to the hard disk drives in the BladeCenter S chassis.
Note: SAS connectivity modules support the use of SAS or SATA hard disk
drives. SAS RAID controller modules support the use of SAS hard disk drives
only.
vHot-swap capabilities
Bays in the BladeCenter S chassis are hot-swappable. For example, you can add,
remove, or replace a blade server or a SAS or SATA hard disk drive without
removing power from the BladeCenter S chassis.
The midplane provides hot-pluggable connectors for the following components:
– Six blade servers
– Four I/O modules
– One advanced management module
– One serial pass-thru module
– Four power modules
– Four fan modules
– Two storage modules
– One media tray
vHigh-availability design
Components in the BladeCenter S system enable continued operation if one of
the components fails:
–Power modules. In normal operation, the power modules provide power to
share the system load. If a power module fails, the working power modules
can continue to handle the entire load. You can replace a power module
without shutting down the BladeCenter S system.
© Copyright IBM Corp. 2007, 2012 1

Note: The power management policy that you have implemented for the
BladeCenter S system determines the result of a power module failure.
Power modules also provide cooling fans for the storage modules. Therefore,
if you are using storage module 1, you must install power modules 1 and 2. If
you are using storage module 2, you must install power modules 3 and 4.
–Fan modules. In normal operation, fan modules share the cooling in the
BladeCenter S system. If one fan module fails, the other three fan modules
handle the entire load. You can replace a fan module without shutting down
the BladeCenter S system.
–BladeCenter S system midplane. The midplane has the following
characteristics:
- Redundant high-speed serialize/deserialize (SERDES) interconnects
between blade servers and switches
- I2C communication between the advanced management module and all
modules (except blade servers)
- RS-485 (EIA 485) communication between the advanced management
module and blade servers
- Analog video connectors from the blade servers to the advanced
management module
- USB connections between the blade servers and the advanced management
module
–Redundant storage access. Installing a pair of SAS connectivity modules or
SAS RAID controller modules in I/O module bays 3 and 4 provides support
for redundant access to the storage modules in the BladeCenter S chassis (if
both storage modules are installed).
vSystems management
The advanced management module is used to communicate with the service
processor in each blade server to provide system monitoring, event recording,
and alerts. You can manage the BladeCenter S chassis, its devices, and the blade
servers remotely.

and the hard disk drives installed in that storage module are commonly referred to
as integrated shared storage because this storage is integrated in the BladeCenter S
chassis and shared among the blade servers in the BladeCenter S system.
Each storage module can support up to six hot-swap, 3.5-inch hard disk drives. If
you are installing SAS connectivity modules, both SAS and SATA hard disk drives
are supported, and you can use both types of hard disk drives in each storage
module. If you are installing SAS RAID controller modules, you must install SAS
hard disk drives.
Within each storage module, hard disk drives are numbered 1 through 6 from left
to right, and top to bottom.
Note: Each hard disk drive bay must contain either a hard disk drive or a
drive-bay filler.
