xxviii IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 31
Chapter 1. Introduction
The IBM TotalStorage DS4500 Fibre Channel Storage Server (referred to
throughout this book as the DS4500 Storage Server) is a high-performance unit that
provides dual, redundant array of independent disks (RAID) controllers and Fibre
Channel interfaces to both the host and drive channels.
DS4500 Storage Server overview
The DS4500 Storage Server (Machine type 1742, models 90U and 90X) supports
direct attachment of up to four hosts that contain two host adapters each, and is
designed to provide maximum host-side and drive-side redundancy. By using
external Fibre Channel switches in conjunction with the DS4500 Storage Server,
you can attach up to 64 hosts with two adapters each to a DS4500 Storage Server.
Each DS4500 Storage Server contains several removable components, called
customer replaceable units (CRUs), that you can access from either the front or
back of the unit. These CRUs include the battery, RAID controllers, storage server
fan, power supplies, fan and communications module, mini hubs, and Small
Form-Factor Pluggable (SFP) modules. The DS4500 Storage Server also has a
removable front bezel.
The DS4500 Storage Server functions with at least one external storage expansion
enclosure containing Fibre Channel or SATA hard drives. The DS4500 Storage
Server supports a maximum of 224 hard drives when the drives are configured
using IBM DS4000 EXP700, DS4000 EXP710, or DS4000 EXP100 storage
expansion enclosures. If the drives are configured using IBM FAStT EXP500
storage expansion enclosures only, a maximum of 220 hard drives are supported.
Attention:
v In order to attach DS4000 EXP100 or EXP710 storage expansion enclosures to
a DS4500 Storage Server, the DS4500 Storage Server controller firmware must
be at version 06.xx.xx.xx or higher. In addition, you must purchase the FC/SATA
Enclosure Intermix premium option to combine EXP100s with EXP700s or
EXP710s in the same DS4500 Storage Server configuration.
v The DS4500 controller units are not compatible with the DS4400 or FAStT500
controller units. The DS4500 controller units are keyed to prevent them from
being mistakenly inserted in the non-supported storage server units. Do not force
fit the controller units or the backplane might be damaged.

Page 35
The DS4500 Storage Server uses fiber-optic cables to connect to other Fibre
Channel devices. The fiber-optic cables that you need depend on the type of optical
connectors in the device to which you are connecting the DS4500 Storage Server. If
the device uses SFP modules or optical interface connectors, then you must use
LC-LC Fibre Channel cables. If the device uses Gigabit Interface Converters
(GBICs) as the optical interface connector, you must use LC-LC Fibre Channel
cables and LC-SC Fibre Channel cable adapters (Part number 19K1250) to connect
to the DS4500 Storage Server.
Handling fiber-optic cables
Before you use fiber-optic cables, read the following precautions.
Attention: To avoid damage to your fiber-optic cables, follow these guidelines:
v Do not route the cable along a folding cable-management arm.
v When attaching to a device on slide rails, leave enough slack in the cable so that
it does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
v Route the cable away from places where it can be damaged by other devices in
the rack cabinet.
v Do not use plastic cable ties in place of the provided cable straps.
v Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
v Do not put excess weight on the cable at the connection point. Be sure that the
cable is well supported.
Using LC-LC Fibre Channel cables
The LC-LC Fibre Channel cable is a fiber-optic cable that is used to connect into
one of the following devices:
v SFP module installed in a DS4500 Storage Server mini hub
v SFP module installed in an IBM Fibre Channel switch
v SFP module installed in an IBM DS4000 EXP700 or DS4000 EXP710 storage
expansion enclosure
v SFP module installed in an IBM DS4000 EXP100 storage expansion enclosure
v Optical interface connector on an IBM DS4000 FC-2 Host Bus Adapter (part
number 19K1246), IBM DS4000 single port FC2-133 Host Bus Adapter (part
number 24P0960), or dual port FC2-133 Host Bus Adapter (part number

Storage Server interface ports are shown in Figure 17.
For more information about how to connect the DS4500 Storage Server and
storage expansion enclosures by using the host and drive interface ports, refer to
the IBM DS4500 Fibre Channel Storage Server Installation and Support Guide.
Host interface ports
The DS4500 Storage Server comes with host-side mini hubs 1 and 2 installed.
Each mini hub provides host loop connectivity and self-diagnostic features. Host
mini hubs connect to the controller in pairs. When fully configured, the DS4500
Storage Server can accommodate four host-side mini hubs, two per controller. Mini
hubs 1 and 3 connect to the top controller (Controller A) and mini hubs 2 and 4
connect to the bottom controller (Controller B), as shown in Figure 18. To ensure
redundancy, you must connect each host to both controllers through the appropriate
mini hub.
Drive interface ports
The DS4500 Storage Server comes with drive-side mini hubs 1 and 2 installed.
Each drive mini hub connects to Controller A and Controller B and represents a
single drive loop. The drive loops must be set up in pairs to support redundant drive
loop configurations (two data paths per storage expansion enclosure). DS4500
Storage Servers use only redundant drive-loop configurations. See Figure 19 on
page 14 for an illustration of the drive-side mini-hub interface ports.
Figure 17. DS4500 Storage Server interface ports
Figure
18. Host-side mini-hub interface ports
Chapter 1. Introduction 13
Page 44
The maximum number of storage expansion enclosures that can be connected per
pair of redundant drive loops depends on the IBM DS4000 storage expansion
enclosure models used. The following DS4000 storage expansion enclosure types
are supported by the DS4500 Storage Server:
v FAStT EXP500
v DS4000 EXP700
v DS4000 EXP710
v DS4000 EXP100
If the drives are configured using only DS4000 EXP700, EXP710, or EXP100
storage expansion enclosures, the DS4500 Storage Server supports a maximum of
224 hard drives.
If the drives are configured using only FAStT EXP500 storage expansion
enclosures, the DS4500 Storage Server supports a maximum of 220 hard drives.
Attention: In order to attach DS4000 EXP100 or DS4000 EXP710 storage
expansion enclosures to a DS4500 Storage Server, the DS4500 Storage Server
controller firmware must be at version 06.xx.xx.xx or higher. In addition, you must
purchase the FC/SATA Enclosure Intermix premium option to combine DS4000
EXP100s with DS4000 EXP700s or DS4000 EXP710s in the same DS4500 Storage
Server configuration.
For detailed information about how to cable the storage server and storage
expansion enclosures, see the IBM TotalStorage DS4500 Fibre Channel Storage
Server Installation and Support Guide and the DS4500 Fibre Channel Cabling
Instructions that come with the storage server.
Intermixing storage expansion enclosure models
Storage expansion enclosure models can be mixed in the same redundant drive
loop or the same pair of redundant drive loops. As described in the following
sections, you can intermix FAStT EXP500s and DS4000 EXP700s, and you can
also intermix DS4000 EXP100s, EXP710s, and EXP700s.
Figure 19. Drive-side mini-hub interface ports
14 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 45
You cannot mix DS4000 EXP100s or DS4000 EXP710s with FAStT EXP500s in any
DS4000 storage server configuration. If a DS4000 EXP100 or DS4000 EXP710 is
attached to the DS4500 Storage Server in one drive loop, no FAStT EXP500s can
be present either in the same drive loop or in the other drive loop.
Note: This restriction exists because the FAStT EXP500 storage expansion
enclosure operates at 1 Gbps only, while the DS4000 EXP100 and DS4000
EXP710 storage expansion enclosures do not operate at 1 Gbps. The
DS4500 Storage Server does not support mixed drive loop speeds.
Intermixing FAStT EXP500s and DS4000 EXP700s: Yo u can intermix FAStT
EXP500 and DS4000 EXP700 storage expansion enclosure models in the same
redundant pair of drive loops.
Attention: If you are intermixing FAStT EXP500s and DS4000 EXP700s, it is
strongly recommended that you do not cable the FAStT EXP500 and DS4000
EXP700 storage expansion enclosure models in the same redundant drive loop
pair. Instead, you should cable the FAStT EXP500 storage expansion enclosures
together using one pair of redundant drive loops, and you should the DS4000
EXP700 storage expansion enclosures together using the other pair of redundant
drive loops.
Note:
You might need to purchase two additional drive mini hubs to implement this
cabling scheme.
If you are intermixing FAStT EXP500s and DS4000 EXP700s, your drive loop
configuration must meet the following requirements:
v The maximum Fibre Channel transfer speed in all of the DS4000 EXP700s must
be set to 1 Gbps because the maximum FC transfer speed of the IBM FAStT
EXP500 storage expansion enclosures is 1 Gbps. Otherwise, a drive channel
mini hub data rate mismatch error will be generated.
v The maximum Fibre Channel transfer speed in all the DS4500 Storage Server
drive-side mini hubs must be set to 1 Gbps.
Attention: If you change the DS4000 EXP700 storage expansion enclosure or
DS4500 Storage Server enclosure link speed setting, you must power-cycle the
storage server. See “Turning off the power” on page 23 and “Turning on the
power” on page 22 for the proper DS4000 configuration power-down and
power-up sequences. For more information, see the IBM TotalStorage DS4000
Hard Drive and Storage Expansion Enclosure Installation and Migration Guide.
If
you intermix FAStT EXP500s and DS4000 EXP700s within a single drive loop,
see Table 8 for the possible combinations of FAStT EXP500 and DS4000 EXP700
storage expansion enclosures per drive loop.

Chapter 2. Operating the DS4500 Storage Server
This chapter describes the tasks required to operate the DS4500 Storage Server.
Best practices guidelines
To ensure optimal operation of your system, always follow these best practices
guidelines:
v Back up the data on your storage drives periodically.
v To maintain power redundancy, plug the DS4500 storage server’s right and the
left power supplies into two independent external power circuits through ac
distribution units inside a rack cabinet or directly into external receptacles.
Similarly, the right and left power supplies of the DS4000 storage expansion
enclosures attached to the DS4500 storage server should be plugged into the
same two independent external power circuits as the DS4500. This ensures that
the DS4500 storage server and all its attached storage expansion enclosures will
have power if only one power circuit is available. In addition, having all the right
or all the left power supplies plug into the same power circuit enables the
components in the storage subsystem to power on simultaneously during an
unattended restoration of power.
v Before any planned system shutdown or after any system additions, removals, or
modifications (including logical drive creations, storage partitioning definitions,
hardware changes, and so on), save the storage subsystem profile as explained
in the DS4000 Storage Manager guide for your operating system. Save the
profile in a location other than the logical drives created for the DS4500 storage
server.
v Ensure that your system is in an optimal state before you shut it down. Never
turn the power off if any fault light is lit; be sure to resolve any error conditions
before you shut down the system.
v During any maintenance or attended power-up procedure, carefully follow the
sequences listed in “Turning on the power” on page 22 and “Turning off the
power” on page 23 for the proper DS4000 configuration power-down and
power-up sequences. Check that each component of the subsystem is
powered-on in the proper order during this entire power-up procedure to ensure
the controller will be able to optimally access all of your storage subsystems.
v A storage system in an optimal state should recover automatically from an
unexpected shutdown and unattended simultaneous restoration of power to
system components. After power is restored, call IBM support if any of the
following conditions occur:
– The storage subsystem logical drives and arrays are not displayed in the
DS4000 Storage Manager graphical user interface (GUI).
– The storage subsystem logical drives and arrays do not come online.
– The storage subsystem logical drives and arrays seem to be degraded.
v
Using the DS4000 Storage Manager client, save the DS4000 subsystem
configuration profile to a disk that is not affected every time you make changes
(such as logical drive creation or modification, or storage partitioning changes) to
the DS4000 subsystem configuration.

Monitoring DS4500 Storage Server
status through software
Run the storage-management
software continuously. This software
checks the storage subsystem for
failures and displays messages that
indicate the types of failures and the
recovery procedures.
“Monitoring status through software”
on page 25
Checking fault indicator lights for
component failures
Component failures are indicated by
lights on the front and back of the
DS4500 Storage Server and are
monitored by the
storage-management software.
Note: The indicator lights identify
problems with the DS4500 Storage
Server components, but you might
need more information to thoroughly
diagnose and repair the unit.
Therefore, it is important to use the
storage-management software to
continuously monitor the status of the
DS4500 Storage Server.

Turning on the power
Important: Yo u must turn on the storage expansion enclosures before you turn on
the DS4500 Storage Server. The controllers might not recognize the correct
configuration if you turn on the hard disk drives after the DS4500 Storage Server.
Always wait at least 30 seconds between the time you turn off a power switch and
the time you turn on the power.
Turn on the power to each device in the following order:
v Supporting devices
v Storage expansion enclosures
v DS4500 Storage Server
v Host
If you are restoring power to the DS4500 Storage Server after an emergency
shutdown or power outage, go to “Overtemperature condition and power supply
shutdown” on page 37.
Use the following procedure to turn on the connected devices and the DS4500
Storage Server:
1. Turn on the power to the supporting devices (for example, Ethernet switches,
Fibre Channel switches, and management stations).
2. Turn on the storage expansion enclosure. The controllers might not recognize
the correct configuration if the drives are powered up after the storage server.
For instructions on turning on the storage expansion enclosures, refer to the
storage expansion enclosure documentation.
3. Turn on the power to the DS4500 Storage Server, as follows:

Depending on the type of operating system on the host server, perform either a
server power cycle, a server restart, or a rescan for hardware on the host
server.
Turning off the power
Attention: The DS4500 Storage Server is designed to run continuously, 24 hours
a day. Except in an emergency, never turn off the power even if any DS4500
Storage Server fault indicator lights are lit. Use the proper troubleshooting or
servicing procedure to correct the fault before you turn off the power. This measure
ensures that the DS4500 Storage Server powers up correctly later. Also do not
power off the storage server to reset it. Use the Reset Controller menu function in
the Storage Manager Client program instead.

Use the following procedure to turn off power to the DS4500 Storage Server:
1. Make sure that all amber fault indicator lights on the DS4500 Storage Server
are off. If any fault indicator lights are on, use the storage-management software
to determine the status of the system components and correct any problems
before you turn off the power. For more information, see “Monitoring status
through software” on page 25 and “Checking the indicator lights” on page 26.
2. Perform any required procedures that are indicated by the operating system
software.
3. Prepare the DS4500 Storage Server for shutdown, as follows:
a. Stop all I/O activity to the DS4500 Storage Server and attached storage
expansion enclosures.
Note: If a parity check is in progress, it might take a long time for the drive
indicator lights to stop blinking.
b. Use the operating system software to disconnect the DS4500 Storage
Server logical drives from the host before you power off the storage server.
c. Make sure that the fast write cache indicator light on each DS4500 Storage
Server front panel and all drive active indicator lights on each storage
expansion enclosure front panel are off (not blinking).
Attention: To turn off all power to the storage server, you must turn off both
power supply switches and disconnect both power cords. Use the procedure in
step 4 for the proper shutdown sequence.
4. Turn off the power to the DS4500 Storage Server or turn off the power to each
device using the following shutdown sequence.
a. Turn off power to the host before you turn off the power to the storage
server. If the host must stay powered on to support an existing network,
refer to the operating system documentation for information about
disconnecting the storage server logical drives from the host before the
storage server is powered off.
b. Turn off power to the storage server before you turn off power to the storage
expansion enclosures. Turn off both power supply switches on the back of
the storage server. See Figure 23 on page 23.
24 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 55
c. Instead of turning off the power to other supporting devices ( for example,
management stations, Fibre Channel switches, or Ethernet switches),
disconnect the communications cables to the supporting devices.
Monitoring status through software
To monitor DS4500 Storage Server status, always run the DS4500 Storage
Manager software and check it frequently. Be sure to enable the management alerts
that you need. The DS4500 Storage Manager software provides the best way to
diagnose and repair DS4500 Storage Server failures. This software can help you:
v Determine the nature of a failure
v Locate a failed component
v Provide recovery procedures to repair a failure
Although the DS4500 Storage Server has fault indicators, these lights are summary
indicators and might not identify the specific component that has failed or needs
replacing, or which type of recovery procedure you must perform. In some cases
(such as loss of redundancy in DS4500 Storage Server drive loops), the fault light
does not come on. Only the storage-management software can detect the failure.
Recovering from a DS4500 Storage Server failure might require you to perform
procedures other than replacing the component. The DS4500 Storage Manager
software gives these procedures when you are using the Recovery Guru menu.
Note: Always follow the software recovery procedures to prevent data loss.
For more information about the DS4500 Storage Manager software, refer to the
Online help or publications that are appropriate for your operating system (see
“About this document” on page xvii for a list of publications).
Firmware updates
In order to ensure the optimal operation of the DS4500 storage server and its
attached storage expansion enclosures, the storage expansion enclosure ESM
firmware, the DS4500 storage server controller firmware, the hard drive firmware,
and the NVSRAM (for controllers only) must be up to date. Go to the following Web
site to get the latest updates.
www.ibm.com/servers/storage/support/disk/
Apply the necessary updates before configuring the DS4500 arrays and logical
drives. Subscribe to My Support for automatic notifications of firmware or storage
manager software updates or any important information about your DS4000
subsystems (see “Product updates” on page 1).
Attention: Read the Readme file that is included in each firmware or DS4000
Storage Manager software package for any limitations, subsystem firmware
prerequisites, or download-sequence information. For example, the controller
firmware code might require the storage expansion enclosure ESM firmware to be
upgraded first to a particular version, or the controller firmware download might
require the halting of I/Os to the DS4500 storage server’s logical drives. Failure to
observe the limitations, prerequisites, and dependencies in the Readme file might
result in a loss of data access.
Chapter 2. Operating the DS4500 Storage Server 25

Checking the indicator lights
The DS4500 Storage Server indicator lights display the status of the DS4500
Storage Server and its components. Green indicator lights mean normal operating
status; amber indicator lights mean a possible failure.
It is important that you check all the indicator lights on the front and back of the
DS4500 Storage Server a few minutes after you turn on the power. After you turn
on the power, the indicator lights might blink intermittently. Wait until the DS4500
Storage Server completes its power up before checking for faults. It can take up to
15 minutes for the battery to complete its self-test and up to 24 hours to fully
charge, particularly after an unexpected power loss of more than a few minutes.
The indicator lights for the components of the DS4500 Storage Server are
described in the following sections.
Storage server indicator lights
The storage server has five indicator lights, as shown in Figure 24 on page 27. To
view the storage server indicator lights, you do not have to remove the DS4500
Storage Server bezel.

Overtemperature condition and power supply shutdown
If the fan and communications module fails or is unable to maintain an internal
temperature below 70° C (158° F), one or both of the power supplies in the DS4500
Storage Server might shut down (see Figure 30). If both power supplies shut down,
the DS4500 Storage Server is not operational.
The storage-management software causes the fan and communications module
fault indicator and storage server fan indicator to light before the temperature has
risen sufficiently to shut down the power supplies. The storage server fan indicator
light, shown in Figure 31, is lit when the DS4500 Storage Server temperature
exceeds 45° C (113° F). The DS4500 Storage Server shuts down if the temperature
rises to 70° C (158° F). If both power supplies shut down, the fault indicator cannot
light.

Turning on the power after an overtemperature shutdown
If your DS4500 Storage Server shuts down unexpectedly and you received a
″Maximum temperature exceeded ″ alert from the storage server before it
shutdown, take the following precautions to cool it before you power on the unit:
1. Turn off the power switches to allow the DS4500 Storage Server to cool.
2. When the room temperature is below the upper operating temperature of 35° C
(95° F), turn on the power switches.
3. Check the DS4500 Storage Server for faults or damage. Use the
storage-management software to check the overall status of the DS4500
Storage Server and its components. Correct any problems indicated.
Turning on the power after an emergency shutdown
Use this procedure to regain normal system operation after a power failure or
emergency shutdown:
1. Check all components and cables for damage. If there is no visible damage,
continue with Step 2; otherwise, service the system.
2. Make sure the power cords are plugged in.
3. Make sure that the circuit breaker, storage expansion enclosures, and storage
server power switches are in the off position.
4. Turn on the circuit breakers in the rack cabinet, and turn on the power switches
on all storage expansion enclosures attached to the DS4500 Storage Server.
Important: Yo u must turn on the storage expansion enclosures before you turn
on the DS4500 Storage Server. The controllers might not recognize the correct
configuration if the attached drives are powered up after the DS4500 Storage
Server. For instructions on how to power up the storage expansion enclosures,
refer to the storage expansion enclosure documentation.
5. Turn on both power switches on the back of the DS4500 Storage Server. For
the location of the power switches, see Figure 23 on page 23.
6. Check the status of the DS4500 Storage Server and other devices. Make sure
all fault indicator lights are off on the front and back of the DS4500 Storage
Server. For more information, see “Checking the indicator lights” on page 26.
7. When all the devices are powered up, check the overall system status by using
the storage-management software.
Checking the battery service date
Note: Replace the battery whenever it fails to hold a charge or every three years.
Operating the DS4500 Storage Server in a hot environment (above 35° C or
95° F) lowers the battery life expectancy.
To check the battery service date, perform the following steps:
1. Remove the DS4500 Storage Server bezel, as shown in Figure 21 on page 21.
38 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide

2. Check the Battery Support Information label, as shown in Figure 32.
The Battery Support Information label on the front of the battery has three
dates:
v Date of Manufacture - Date the battery was built at the factory
v Date of Installation - Date the battery was installed in the DS4500 Storage
Server
v Replacement Date - Battery replacement date (see the note at the beginning
of this section)
3.
Perform one of the following tasks:
v If it is time to replace the battery, install a new battery using the procedure
described in “Replacing a failed battery” on page 47.
v If it is not time to replace the battery, replace the DS4500 Storage Server
bezel, as shown in Figure 22 on page 22.
Preparing to move the DS4500 Storage Server
Remove each component CRU before you move the DS4500 Storage Server to a
new location or before you remove the chassis from its rack cabinet. This
precaution helps safeguard the equipment and ensures a smoother transition to the
new environment.
If you are moving the DS4500 Storage Server a short distance, and you have
sufficient assistance or equipment, you might be able to move the DS4500 Storage
Server without removing each component CRU. If you do not have sufficient
assistance or equipment, use the procedure in “Moving or relocating the DS4500
Storage Server” on page 40 to safely move the equipment to its new location.

Chapter 3. Replacing the DS4500 Storage Server components
The DS4500 Storage Server contains two RAID controllers, a cooling system that
contain four fans, mini hubs, SFP modules, and a power system. This chapter
includes detailed instructions on how to replace these components.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective package until
you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the system unit for at least two seconds. (This drains static
electricity from the package and from your body.)
v Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it in its
static-protective package. Do not place the device on your system unit cover or
on a metal table.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
DS4500 Storage Server controller
The DS4500 Storage Server supports RAID technology. The DS4500 Storage
Server contains two RAID controllers.
Each controller comes in a removable, portable unit, called a controller CRU, as
shown in Figure 34 on page 45. Each controller CRU slides into one of two
controller slots on the front of the DS4500 Storage Server and attaches to hosts
through Fibre Channel connections. Two handles lock the controller in place. Each
controller slot has a controller slot designation that identifies the physical location of
the controller in the chassis: controller slot A (top) or controller slot B (bottom). Each
controller CRU has ten indicator lights: one power, one fault, and eight status
indicator lights, as shown in Figure 33 on page 44.
© Copyright IBM Corp. 2005 43
Page 74
Attention: If you are removing both controllers (controller A and controller B) from
the DS4500 Storage Server, label controllers A and B with the white tape dots that
are included in the rack mounting assembly kit. To prevent data loss, the controllers
must be installed into their original location.
Servicing notes
Consider the following factors when servicing the controllers in the DS4500 Storage
Server:
v The DS4500 Storage Server supports two controller CRUs, which attach to hosts
through Fibre Channel connections.
v You can hot swap or replace a failed controller while the DS4500 Storage Server
is in operation as long as the host has a Fibre Channel connection to the
functioning controller and is in a “passive” or “offline” status in the
storage-management software.
v If cache mirroring is enabled in redundant controllers and one controller fails, the
second controller assumes processing functions without data loss. However,
some or all data might be lost if cache mirroring is disabled and a failure occurs
before data is written from cache memory to disk.
v If you replace the controller CRU and still experience problems, the DS4500
Storage Server might have other defective components or connections. Check
the storage-management software for indications of other component failures.
v When a controller CRU fails, the fault light on the affected controller is lit. For
more information about indicator lights, see “RAID controller indicator lights” on
page 28.
Figure 33. Controller status indicator lights
44 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 75
v The two controllers are automatically synchronized when you replace a failed
controller. The storage-management software automatically synchronizes the
firmware between the existing controller and the new controller.
Replacing a failed controller
When instructed by the storage-management software, replace a controller CRU by
using the following procedure.
Attention: After replacing a controller, always use the storage-management
software to verify the firmware levels.
1. Remove the DS4500 Storage Server bezel, as shown in Figure 21 on page 21.
Attention: Removing a controller that is operating normally (not failed) can
result in data loss. Only remove a controller that:
v Has a fault indicator light that is lit
v Is marked as “Failed” (offline) through the storage-management software
2. Using Figure 34 as a guide, remove the controller that has failed.
a. Using your thumbs, squeeze the two center tabs and pull both controller
handles outward with your fingers.
b. Using both handles, pull out on the controller to remove it.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 43.
3. Unpack the new controller. Using the proper handling precautions, remove the
new controller from the packing material.
Check the shipping invoice and the controller to make sure that it has the same
memory size as the controller that you just removed.
4. Using Figure 34 as a guide, install the new controller as follows:
a. Using your thumbs, squeeze the two center tabs and pull both controller
handles outward with your fingers.
b. Using the handles, slide the controller into the slot until the back edge of
both handles hooks onto the frame.
Figure 34. Removing and replacing a failed controller CRU
Chapter 3. Replacing the DS4500 Storage Server components 45
Page 76
c. Close both handles and snap into place.
5.
Using Figure 35 as a guide, check the controller indicator lights.
v If the green power indicator light is on and the amber fault indicator light is
off, go to Step 8.
v If the green power indicator light remains off or the fault indicator light is on
after a few seconds, make sure that the controller CRU is locked into place. If
the fault indicator light remains on, go to Step 6.
6. Use the storage-management software to check the status of both controllers. If
applicable, perform the recovery procedures required by the software. If this
corrects the fault and the DS4500 Storage Server is operating without error, go
to Step 8. If not, go to Step 7.
7. Reinsert the controller CRU. Then, if there are no error messages or controller
faults, go to Step 8. If there is still a problem, call for service.
8. Replace the DS4500 Storage Server bezel, as shown in Figure 22 on page 22.
Battery
The battery CRU contains rechargeable batteries and a battery-charger board. The
battery CRU plugs into the front of the DS4500 Storage Server (see Figure 36 on
page 48) where it provides backup power to the cache memory in both controllers.
During a power outage, a properly charged battery CRU maintains electrical current
to the controllers for up to five days with 1 Gb cache memory installed. All data
stored in memory is preserved as long as the batteries can sustain power to the
cache memory. However, the battery does not provide power to the rest of the
system during a power outage. Therefore, the system is not able to write data to
hard disk drives without a backup power source.
Servicing notes
Consider the following factors when you service the battery in the DS4500 Storage
Server:
v The battery has a three-year life expectancy. Replace the battery every three
years or whenever it fails to hold a charge. Operating the DS4500 Storage
Server in an unsupported environment (above 35° C or 95° F) lowers the life
expectancy of the battery.
v The service label on the battery provides a blank line for recording the date on
which the battery was last serviced (see Figure 37 on page 49). Check this label
to determine when to replace the battery. For information about using the
software to track battery age, refer to the IBM DS4000 Storage Manager online
help.
Figure 35. Indicator lights on the DS4500 Storage Server bezel
46 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 77
v When a battery fails, the fault light on the battery is lit. For more information
about indicator lights, see “Battery indicator lights” on page 30.
v If you replace the battery and still experience battery problems (for example, loss
of battery power to the controllers or batteries not charging properly), the DS4500
Storage Server might have defective components or connections. Check the
storage-management software for indications of other component failures.
Replacing a failed battery
When instructed by the storage-management software, replace the battery.
Attention: Because the battery CRU is a sealed unit, you must replace the entire
CRU (not just the batteries) in order to keep the battery backup system in working
order. Opening the battery CRU voids your warranty.
1. Use the storage-management software to disable caching. Caching is disabled
when the Cache active (Fast write cache) indicator light is off. Data in cache is
unprotected if a power outage occurs while the battery CRU is out of
operation.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 43.
Statement 8:
CAUTION:
Never remove the cover on a power supply or any part that has the
following label attached.
Hazardous voltage, current, and energy levels are present inside any
component that has this label attached. There are no serviceable parts
inside these components. If you suspect a problem with one of these
parts, contact a service technician.
2. Remove the DS4500 Storage Server bezel, as shown in Figure 21 on page 21.
Attention: Be careful when you remove the battery. The battery weighs
approximately 6.4 kg (14 lb).
3. Using Figure 36 on page 48 as a guide, remove the battery.
a. Loosen the four captive screws on the battery. If necessary, use a flat
blade screwdriver to loosen the screws.
b. Using both pull handles, slide out the battery about 5 cm (2 in.).

using the storage-management software. The software continues to issue
battery-related errors if the installation date is not reset.
Storage server fan
The storage server fan is a single, removable unit that contains two cooling fans
and temperature monitoring circuitry. The storage server fan plugs directly into a
slot on the front of the DS4500 Storage Server, to the left of the controllers (see
Figure 40 on page 52). Five indicator lights provide overall system status
information (see Figure 41 on page 53). The dual fans in the storage server fan unit
provide a redundant cooling system to both controller CRUs. If one fan fails, the
other continues to operate, providing sufficient air circulation to prevent the
controllers from overheating until you can replace the entire storage server fan.
To prevent cooling problems, the DS4500 Storage Server must have proper air
circulation throughout the chassis. Cooling problems include any malfunctions or
obstructions that impede air flow and cause one or more components in the
DS4500 Storage Server to overheat. Make sure that the ambient air temperature
around the DS4500 Storage Server is within the environmental requirements. To
boost air circulation, the DS4500 Storage Server chassis has air vents along its top
and sides. These vents serve as air intake and exhaust passages. Always keep
vents clean and free of obstructions (Refer to the IBM DS4500 Fibre Channel
Storage Server Installation and Support Guide for operating specifications).

Page 81
Figure 39 shows the DS4500 Storage Server air flow. Make sure your installation
site allows adequate ventilation to the DS4500 Storage Server during operation.
Note: Allow at least 60 cm (2 ft) of clearance in front of and behind the DS4500
Storage Server for proper ventilation.
Servicing notes
Consider the following factors when you service the storage server fan:
v The storage server fan and the fan and communications module cooling system
failing simultaneously in the storage server is unlikely. Such a failure will cause
either one or both controllers to overheat. Under these circumstances, the amber
controller light on the front panel might be lit. If this occurs, shut down the
DS4500 Storage Server immediately and let the unit cool to room temperature
and then replace the storage server fan.
v You can hot swap, or replace, the storage server fan, as long as you complete
the exchange within 15 minutes. The time limit applies to the total time that the
fan is out of the chassis. The time begins when you remove the failed storage
server fan and ends when you install the new one. This does not include the time
it takes to perform the entire procedure (for example, checking the indicator
lights).
v When a storage server fan fails, the fault light on the storage server fan is lit. For
more information about indicator lights, see “Storage server indicator lights” on
page 26.
v If you replace the storage server fan and still experience problems, the DS4500
Storage Server might have defective components or connections. Check the
storage-management software for indications of other component failures.
v The storage server fan indicator light is also used to indicate a fan and
communications module failure. Be sure to check the storage server fan and fan
and communications module before you call for service.

Replacing a failed storage server fan
When instructed by the storage-management software, replace the storage server
fan.
1. Remove the DS4500 Storage Server bezel, as shown in Figure 21 on page 21.
Attention: To prevent damage to the DS4500 Storage Server components, do
not operate the DS4500 Storage Server without adequate ventilation to the
controllers. If it will take longer than 15 minutes to replace the storage server
fan, you must shut down the DS4500 Storage Server to prevent it from
overheating. The time limit applies to the total time that the fan is out of the
chassis. For more information, see “Turning off the power” on page 23.
2. Remove the failed storage server fan, as shown in Figure 40.
a. Lift up the lever on the storage server fan.
b. Pull firmly on the bottom lip to remove the fan.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 43.
3. Unpack the new storage server fan.
4. Install the new storage server fan.
a. Slide the new storage server fan all the way into the slot.
b. Press down on the lever and snap the lever into place.
Figure 40. Removing and installing the storage server fan
52 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 83
5. Using Figure 41 as a guide, check the storage server indicator lights on the fan.
v When the storage server fan is operating properly, the green power indicator
is lit and the amber fan indicator is off.
v If the amber fan indicator is lit or the green power indicator remains off, make
sure that the storage server fan is seated securely in the slot and that the
lever is snapped into place. Check the storage server fan or the fan and
communications module status.
v If the storage server fan indicator remains on, it might indicate a problem with
the new storage server fan or the fan and communications module (both
components share the same indicator light). Replace the storage server fan
with a spare, if available. Otherwise, turn off the DS4500 Storage Server to
prevent it from overheating until you can replace the fan.
6.
Replace the DS4500 Storage Server bezel, as shown in Figure 22 on page 22.
Fan and communications module
The fan and communications module is a single, removable unit that contains two
cooling fans and two Ethernet ports. This module plugs into a slot at the center
back of the DS4500 Storage Server, just above the power supplies (see Figure 43
on page 55). It has two captive screws and a rectangular handle for securing and
removing the fan and communications module. The module contains dual fans that
provide a redundant cooling system to both power supplies. If one fan within the
module fails, the other continues to operate. A single fan provides sufficient air
circulation to prevent the power supplies from overheating until you can replace the
entire fan and communications module.
Figure 41. Storage server indicator lights
Chapter 3. Replacing the DS4500 Storage Server components 53
Page 84
Servicing notes
Consider the following factors when you service the fan and communications
module:
v The fan and communications module contains two Ethernet connections used for
direct network-management.
v You can hot swap the fan and communications module as long as you complete
the exchange within 15 minutes from when you remove the failed unit until you
install the new one.
v It is unlikely that the storage server fan and the fan and communications module
cooling system will fail simultaneously. Such a failure will cause one or both
power supplies to overheat. In these circumstances, the amber power supply
indicator light on the bezel is lit and the overheated power supply automatically
shuts down (the green power indicator light on the power supply turns off). Once
the ambient air temperature cools below 70° C (158° F), the power supply
automatically turns on. Replace the failed fan and communications module. Then
check the power supply indicator lights (fault indicator light on the front and
power indicator light on the back). If the power supply fault indicator light remains
on, replace the power supply. For more information about indicator lights, see
“Fan and communications module indicator light” on page 31 and Figure 28 on
page 32.
v If you replace the fan and communications module and still experience problems,
the DS4500 Storage Server might have defective components or connections.
Check the storage-management software for indications of other component
failures.
Replacing a failed fan and communications module
When instructed by the storage-management or diagnostic software, replace the fan
and communications module.
Attention: To prevent damage to the DS4500 Storage Server circuitry, do not
operate the DS4500 Storage Server without adequate ventilation to the power
supplies and mini hubs. If it will take longer than 15 minutes to replace the fan and
communications module, you must shut down the DS4500 Storage Server to
prevent it from overheating. The time limit applies only to the total time that the fan
and communications module is out of the chassis. The time begins when you
remove the failed module and ends when you install the new one. This does not
include the time it takes you to perform this entire procedure (for example, checking
the indicator lights).

communications module is inserted all the way into the chassis and secured
in place.
v If the fault indicator light remains on, one or both fans inside the fan and
communications module might be malfunctioning. Replace the failed fan and
communications module with a spare, if available. Otherwise, shut down the
DS4500 Storage Server until you can replace the failed fan and
communications module with a new one.
6.
Reconnect the interface cables that you disconnected in Step 1 on page 55 to
the new fan and communications module.
Power supply
The DS4500 Storage Server power system consists of two power supplies. The
power supplies slide into either of the two slots on the back of the DS4500 Storage
Server. The power supplies provide power to the internal components by converting
incoming ac voltage to dc voltage. The power supplies are interchangeable and
redundant. Each power supply uses one power cord. You can plug both power
cords into a common power source or plug each cord into a separate circuit for
power redundancy. One power supply can maintain electrical power to the DS4500
Storage Server if the other power supply is turned off or malfunctions.
Servicing notes
Consider the following factors when you service the power supplies:
v Each power supply has a built-in sensor that detects the following conditions:
– Overvoltage
– Overcurrent
– Overtemperature
If any of these conditions occur, one or both power supplies enter shutdown
mode. All power remains off until one of the following events occurs:
– You cycle the power switches (turn off the power switches, wait at least 30
seconds, then turn on the power switches). For more information, see
“Overtemperature condition and power supply shutdown” on page 37.
– The power supplies automatically resume operation when the ambient air
temperature cools to below 70° C (158° F). When the power supplies
automatically resume operation, the DS4500 Storage Server also resumes
operation.
v
You can hot swap (replace) a power supply because the two power supplies
provide redundancy.
56 IBM TotalStorage DS4500 Fibre Channel Storage Server: User’s Guide
Page 87
v Both power supplies have built-in temperature sensors designed to prevent the
power supplies from overheating. If a temperature sensor detects an ambient air
temperature greater than 70° C (158° F), the “overheated” power supply
automatically shuts down. The second power supply remains on as long as its
temperature remains below 70° C (158° F). If the second power supply
overheats, it turns off all power to the DS4500 Storage Server.
Note: There is a serious problem if the air temperature inside the rack cabinet is
hot enough to cause the power supplies to shut down.
v The DS4500 Storage Server is capable of power-up recovery without operator
intervention. Once the air temperature cools to below 70° C (158° F), the power
supplies automatically restart. An automatic restart resets the controllers,
attempts to restart the hard disk drives, which has no effect on the hard disk
drives if they are already running, and returns the DS4500 Storage Server to
normal operation.
v When a power supply fails, the green power indicator light on the power supply
goes off and the amber power supply fault light is lit on the front of the DS4500
Storage Server. For more information, see “Power supply indicator light” on page
32 and “Storage server indicator lights” on page 26.
v If you replace the power supply CRU and still experience problems, the DS4500
Storage Server might have defective components or connections. Check the
storage-management software for indications of other component failures.
Replacing a failed power supply
When instructed by the storage-management software, replace a power supply.
1. Check the power supply indicator light on the back of the DS4500 Storage
Server, as shown in Figure 44. Be sure that the green power indicator light on
the failed power supply is off.

Small Form-Factor Pluggable (SFP) modules
Small Form-Factor Pluggable (SFP) modules are used to connect mini-hub ports to
attached nodes. An SFP module slides into a mini-hub port on the back of the
DS4500 Storage Server and then a host or drive-interface cable connects into the
SFP module. For more information, see “Fibre Channel connections” on page 4 and
“Mini hubs” on page 63.
Servicing notes
Consider the following factors when you service SFP modules:
v The SFP module housing has an integral guide key designed to prevent you from
inserting the SFP module improperly.
v Use minimal pressure when you insert the SFP module into a mini-hub port.
Forcing the SFP module into a port could cause damage to the SFP module or
the port.
v You can insert or remove the SFP module while the storage server is powered
on.
v The operational loop performance is not affected when you install or remove an
SFP module.
Figure 45. Removing and installing a power supply CRU
Chapter 3. Replacing the DS4500 Storage Server components 59

v You must insert the SFP module into a mini-hub port before you connect the
fiber-optic cable.
v You must remove the fiber-optic cable from the SFP module before you remove
the SFP module from the mini hub.
v Four indicator lights on a mini hub provide status information. If an SFP module
fails, the corresponding SFP port bypass indicator will be lit on the mini hub. For
more information, see “Mini-hub indicator lights” on page 32.
v If you replace the SFP module and still experience problems, the DS4500
Storage Server might have defective components or connections. Check the
storage-management software for indications of other component failures.
v Do not mix long-wave SFPs and short-wave SFPs on a single storage server.
Use either long-wave SFPs or short-wave SFPs. Yo u can use the DS4000
Storage Manager client to view the Storage Subsystem Profile in order to verify
that you are not mixing long-wave and short-wave SFPs.
Attention: In addition, do not use long-wave SFPs or GBICs in any of the FC
ports in the FC drive loops. (Long-wave SFPs and GBICs are not supported for
use in the drive ports of storage expansion enclosures. Long-wave SFPs and
GBICs are only supported in the host ports of the DS4000 storage server).
Replacing a failed SFP module
When instructed by the storage-management software, complete the following steps
to replace an SFP module from the mini hub.
Statement 3:
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or
