viii BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide
Chapter 1. General information
The IBM®BladeCenter E Type 8677 and 1881 unit is a high-density,
high-performance rack-mounted system developed for medium-to-large businesses.
It supports up to 14 blade servers, making it ideally suited for networking
environments that require a large number of high-performance servers in a small
amount of space. The BladeCenter system provides common resources that are
shared by the blade servers, such as power, cooling, system management, network
connections, and input/output (I/O) ports (diskette drive, optical drive, ports for USB,
keyboard, video, mouse, and network interfaces). The use of common resources
enables small blade server size, minimizes the cabling required in a working
configuration, and eliminates resources sitting idle.
Performance, ease of use, reliability, and expansion capabilities were key
considerations during the design of your BladeCenter system. These design
features make it possible for you to customize the system hardware to meet your
needs today, while providing flexible expansion capabilities for the future.
Notes:
1. Current BladeCenter E models do not have a diskette drive in the media tray.
Older BladeCenter E models do have a diskette drive in the media tray. In this
document, this difference is noted, when necessary, to describe differences that
exist between current and older model offerings.
2. The illustrations in this document might differ slightly from your actual hardware:

Rear system LED panel: The LEDs on this panel provide status information for
your BladeCenter unit. These LEDs duplicate the LEDs in the front system LED
panel, see “System LED panel” on page 17 for more information about these LEDs.
Blower module:
Blower error
LEDs
Important: If the ambient temperature is 72° F or below, the BladeCenter blowers
will run at 30% of their maximum rotational speed, increasing their speed as
required to control internal BladeCenter temperature. If ambient temperature is
above 72° F, the blowers will run at 80% of their maximum rotational speed
increasing their speed as required to control internal BladeCenter temperature.
Blower error LEDs: The amber LED on each blower is lit and stays lit when an
error has been detected in the blower. The system-error LED on the BladeCenter
system LED panels is also lit. For additional information, see “Identifying problems
using the Light Path Diagnostics feature” on page 29.
I/O (switch) module: See the documentation that comes with each I/O module for
a description of the LEDs on the I/O module.
Power module: Several types of power module, with different wattage ratings, can
be used in the BladeCenter E unit.

Chapter 1. General information 15
The following illustration shows the rear view for the currently available power
modules.
Power module LEDs: These LEDs indicate the condition of the power module. For
additional information, see “Identifying problems using the Light Path Diagnostics
feature” on page 29.
v AC power: When this green LED is lit, ac input to the power module is present
and within specifications. During typical operation, both the ac and dc power
LEDs are lit. For any other combination of LEDs, see “Identifying problems using
the Light Path Diagnostics feature” on page 29.
v DC power: When this green LED is lit, the dc output from the power module to
the other components and blade servers is present and within specifications.
During typical operation, both the ac and dc power LEDs are lit. For any other
combination of LEDs, see “Identifying problems using the Light Path Diagnostics
feature” on page 29.
v Power module error LED (2320-watt power modules only): When this amber
LED is lit, it indicates that an error has been detected in the power module.
When this LED is lit, the BladeCenter unit system error LED is also lit.
Management module: The type of management module that is installed in your
BladeCenter unit depends on the BladeCenter unit model and devices that are
installed.
v A BladeCenter unit that has a media tray with a diskette drive can use either a
management module or an advanced management module, depending on which
devices are installed in the BladeCenter unit.
v A BladeCenter unit that has a media tray without a diskette drive must use an
advanced management module.
v If 2320-watt power modules are installed in the BladeCenter unit, you must use
an advanced management module.
v See the documentation that comes with your BladeCenter device to determine if
a specific management module type is required to support the device.
See the documentation for your management module for additional information and
instructions.

System LED panel
The following illustration shows the status LEDs on the system LED panels on the
front and rear of the BladeCenter unit.
Power-on
Location
Over-temperature
Information
System error
Attention: If the power-on LED is off, it does not mean there is no electrical
current present in the BladeCenter unit. The LED might be burned out. To remove
all electrical current from the BladeCenter unit, you must unplug all power cords
from all power modules.
Note: You can turn off the location LED and the information LED through the Web
interface or the IBM Director console.
Power-on: When this green LED is lit, power is present in the BladeCenter unit.
When this LED is off, the power subsystem, the ac power, or the LED has
failed, or the management module is not present or not functioning.
Location: When this blue LED is lit or flashing, it has been turned on by the
system administrator to aid in visually locating the BladeCenter unit. If a blade
server requires attention, the location LED on the blade server usually will also
be lit. After the BladeCenter unit has been located, you can have the system
administrator turn off the location LED.
Over-temperature: When this amber LED is lit, the temperature in the
BladeCenter unit exceeds the temperature limits, or a blade server has reported
an over-temperature condition. The BladeCenter unit might have already taken
corrective action, such as increasing the blower speed. This LED turns off
automatically when there is no longer an over-temperature condition.
Information: When this amber LED is lit, a noncritical event has occurred that
requires attention, such as the wrong I/O module inserted in a bay or power
demands that exceed the capacity of power modules currently installed. The
event is recorded in the event log. Check the LEDs on the BladeCenter unit and
the blade servers to isolate the component. After the situation is handled, have
the system administrator turn off the information LED.
Note: The information LED will also light if the system error log is 75% full.
System-error: When this amber LED is lit, it indicates that a system error has
occurred, such as a failed module or a system error in a blade server. An LED
on one of the components or on a blade server is also lit to further isolate the
error. (For more information, see “Identifying problems using the Light Path
Diagnostics feature” on page 29.)
Setting up the BladeCenter unit
This section briefly discusses considerations for the setup of your BladeCenter unit.
v Blade bays must be occupied at all times.
To help ensure proper cooling, performance, and system reliability, make sure
that each of the blade bays on the front of the BladeCenter unit has a blade
server, expansion unit, or filler blade installed.
Important: When replacing a blade server or installing an expansion option, do
not operate the BladeCenter unit for more than one minute without either a blade
server, an expansion option, or a filler blade installed in each blade bay.
Chapter 1. General information 17
v Module bays must be occupied at all times.
To help ensure proper cooling, performance, and system reliability, make sure
that each of the module bays on the rear of the BladeCenter unit has a module
or filler module installed.
Important: When replacing a module, do not operate the BladeCenter unit for
more than one minute without either a module or a filler module installed in each
module bay.
v There is no power switch on the BladeCenter unit.
The BladeCenter unit does not have a power switch. Plugging the power cords
into the power modules and a 220 V ac power source (rack-mounted 220-volt
PDU) starts the BladeCenter unit (the management module, I/O modules, and
blowers start running).
Each blade server in the BladeCenter unit has an individual power-control button
behind the control-panel door on the blade front that turns on or turns off the
blade server. Be sure to shut down the operating system before turning off the
blade server, to avoid damaging the hard disk drives.
Notes:
1. The blade server power button turns on or turns off the blade server if local
power control has not been disabled through the management module.
2. The blade server power button turns on the blade server only if the green
power light on the blade server is flashing slowly. If the light flashes rapidly,
the blade server has not yet synchronized with the management module, and
the power button will have no effect.
See the IBM BladeCenter Type 8677 Installation and User’s Guide for more
information about the BladeCenter unit. See the Installation and User’s Guide for
your blade server for more information about the blade server power controls and
turning on or turning off the blade server.
v The removable media drives are detected as a Universal Serial Bus (USB)
device
The removable media drives in the BladeCenter unit are viewed as a USB
devices by the operating system in the blade server. Make sure that your
operating system provides USB support.
v Hot-swap capabilities
The front bays on the BladeCenter unit are hot-swap blade bays; the rear bays
on the BladeCenter unit are hot-swap module bays. You can add, remove, or
replace blade servers or management, I/O, power, or blower modules in
hot-swap bays without removing power from the BladeCenter unit.
Attention: To maintain proper system cooling, each unoccupied bay must
contain a filler blade and an expansion or filler module. When replacing a blade
server or installing an expansion option, do not operate the BladeCenter unit for
more than one minute without either a blade server, an expansion option, or a
filler blade installed in each blade bay or without a module or filler installed in
each rear bay.
18 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide
Connecting to the default IP address on a new BladeCenter
A newly-installed (out-of-the-box) BladeCenter unit tries to locate a DHCP server on
the network before it will default to the factory-configured static IP address in the
management module. This is the initial configuration setting. When there is no
DHCP server on the network the BladeCenter unit is connected to, it can take
several minutes before the management module uses the default (static) IP
address. When the DHCP search times out and the management module uses the
static IP address, you can change the management module configuration so that it
will not attempt to locate a DHCP server.
See the Installation Guide and User's Guide or Command-Line Interface Reference
Guide for your management module type for information about connecting to and
configuring the BladeCenter management module.
Registering and profiling the BladeCenter products
You can register and profile the BladeCenter unit and blade servers on the World
Wide Web.
v To register, go to: http://www.ibm.com/support/mysupport/
v To profile, go to: http://www.ibm.com/systems/support/
Important:
1. Do not switch control of a shared removable media drive to another blade
server until the activity lights on the drive is off, indicating that no read or write
operations are in progress. Before you remove a hot-swap blade server from
the BladeCenter unit, you must shut down the operating system and turn off the
blade server. You do not have to shut down the BladeCenter unit itself.
2. It can take approximately 20 seconds for the operating system in the
switched-to blade server to recognize the removable media drives and USB port
or the keyboard, video, and mouse.
a. The system-error LED might light, and a KVM allocation error might be
logged if the change in ownership for the removable media drives and USB
port or the keyboard, video, and mouse takes more than 8 seconds. The
system-error LED will go off after the ownership change is complete.
b. It can take up to 48 seconds after a blade server is initially turned on before
you can attempt to switch KVM control to that blade server.
