Overview

Disk
Drive
(0 - 14)

The Model CX200-Series of 2-gigabit disk processor enclosures
(DPE2), shown in Figure 1-1, are intelligent, high-performance,
high-capacity disk-array storage systems that use a Fibre Channel
Arbitrated Loop (FC-AL) or fabric as their interconnect interface.
Each enclosure is only 3U (5.25 inches) high, but can include 15 hard
disk drives. The system’s modular, scalable design provides
additional disk storage as your needs increase. The examples and
illustrations in this manual show the rackmounted DPE2 in a
standard 40U EMC cabinet.

1-2

Front
Bezel

Figure 1-1 Model CX200 Disk Processor Enclosure (DPE2)

A standard CX200 can support one additional disk-array enclosure
(DAE2, also called an array module). A DAE2 is a basic 15-disk
enclosure without a storage processor (SP). The CX200 and DAE2
together support up to 30 disk modules in a single disk-array storage
system.

Economical CX200LC systems do NOT support an additional DAE2.

EMC CX200-Series DPE2 Hardware Reference

Rackmount
Cabinet

EMC2164

You can place the DAE2 in the same cabinet as the CX200, or in a
separate cabinet. The CX200-Series systems connect to the external
Fibre Channel environment using small form factor SFF LC optical
transceivers on the storage processor. High-availability features are
standard. The EMC Access Logix™ software option provides Storage
Group functionality for the CX200 and CX200LC.

CX200-Series Components

The CX200-Series storage system includes:

◆ A CX200 DPE2 consisting of

• A sheet-metal enclosure with a midplane and front bezel

• Two storage processors (SPs)

• Five to fifteen disk modules

• A single standby power supply (SPS)

• Two power supply/system cooling modules

Blowers integrated in the power/cooling modules cool the entire
enclosure. The CX200 does not require discrete fan assemblies.

or

About the CX200-Series DPE2

◆ A CX200LC DPE2 with

• A sheet-metal enclosure with a midplane and front bezel

• One storage processor

• Three to fifteen disk modules

• One power supply/system cooling (power/cooling) module

•One blower module

Standard CX200 systems can support an optional single DAE2 with
as many as fifteen disk modules.

Any unoccupied disk module slot has a filler module to maintain air
flow.

The storage processors, disk modules, power/cooling modules,
blower modules, and filler modules are field replaceable units
(FRUs). You can add or replace them without tools and, in most cases,
while the array is powered up.

The disk modules are FC-AL compliant and support dual-port FC-AL
interconnects through the storage processors and their cabling.

CX200-Series Components

1-3

About the CX200-Series DPE2

(

)

A CX200 system can continue running in a degraded mode with one
operating power supply and one functioning SP. You should replace a
failed FRU as soon as possible.

Figures 1-2 through 1-4 show the enclosure components. Where the
enclosure provides slots for two identical components, the
components are called component-name A or component-name B, as
shown in the illustrations.

For increased clarity, the following figures 1-2 through 1-10 depict the DPE2
outside of the rack cabinet. Your enclosure may be installed in a rackmount
cabinet as shown in Figure 1-1.

As shown in Figure 1-2, the front LED display contains two status
lights for each disk module, and two disk enclosure status lights. The
status lights are visible with the front bezel installed.

Storage Processors

The SP is the CX200’s intelligent component. It combines the
functions of a typical storage processor circuit board and a disk
enclosure link control card into a single module.

Full high availability with write caching requires two storage processors.

The CX200-Series SP has the following ports:

◆ COM 1 serial port

◆ COM 2 serial SPS port for communication with the standby

power supply in a standard CX200 system

◆ Network port for storage-system management

◆ One high speed serial data connector (HSSDC) back-end (BE)

port for the FC-AL loop to the disks in a DAE2 (not supported in
CX200LC systems)

◆ Two fibre-optic front-end (FE) connectors, for connecting to the

external Fibre Channel environment (switch or host).

About the CX200-Series DPE2

The storage processor communicates with internal disks through the
midplane. It connects to external link control cards (LCCs) and disks
via an external FC-AL loop (bus). The SP-LCC interface is called the
SP back end.

On a highly available CX200 system, you can replace either storage
processor module while the CX200 is running. Since a CX200LC
system does not include redundant SPs, failure or removal of the
single SP will cause a system failure.

You should never attempt to replace any of the SP’s components.

Disk Modules

!

CAUTION

Pulling out a CX200 SP will cause a failover. (A failover is the
automatic transfer of one or more LUNS from one SP to another, if
a failure occurs in the path of the original SP.)

CX200 SPs are paired. If you remove both storage processors
simultaneously, neither SP can save cached data to disk.

Each disk module, shown in Figure 1-8, consists of one 12-volt Fibre
Channel disk drive in a carrier. You can add or remove a disk module
while the CX200 is powered up, but you should exercise special care
when removing drives while they are in use.

◆ FC-AL

◆ FC-AL Private Loop Direct Attach (PLDA) Profile

◆ 2-Gbit Fibre Channel interface

EMC CX200-Series DPE2 Hardware Reference

Drive Carrier The disk drive carrier is a metal and plastic assembly that provides

smooth, reliable contact with the enclosure slot guides and midplane
connectors. It has a handle with a latch and spring clips. The latch
holds the disk module in place to ensure proper connection with the
midplane. Disk drive Activity/Fault LEDs are integrated into the
carrier.

Drive modules are extremely sensitive electronic components. Refer to the
instructions on Handling FRUs and Replacing or Adding a Disk Module in
Chapter 3 whenever you handle a disk module.

Power Supply/System Cooling Modules

The power supply/system cooling (power/cooling) modules are
located above the SPs. The units integrate independent power supply
and dual-blower cooling assemblies into a single module. CX200LC
enclosures use one power\cooling assembly and a blower-only
module that includes dual blowers but no power supply.

Each power supply is an auto-ranging, power-factor-corrected,
multi-output, off-line converter with its own line cord and on/off
switch. Each supply supports a fully configured DPE2 and shares
load currents with the other supply. The drives and SPs have
individual soft-start switches that protect the disk drives and SPs if
you install them while the disk enclosure is powered up. A FRU
(disk, SP, blower, or power/cooling module) with power-related
faults will not adversely affect the operation of any other FRU.

About the CX200-Series DPE2

The system cooling assembly includes two dual-blower modules. If
one blower fails, the others will speed up to compensate. If two
blowers in a system (both in one power/cooling or blower module,
or one in each module) fail, the CX200 will go off line within two
minutes.

Each power/cooling module has visible status lights. The rightmost
LED indicates power to the supply; the LED adjacent to it indicates a
power supply fault. The leftmost LED (the single LED in a CX200LC
blower module) indicates a failure in one of the integrated blowers
within that module. The status lights are described in Monitoring
CX200-Series Status in Chapter 3.

Figure 1-9 shows a rear view of a CX200 power/cooling module; note
that a CX200LC blower and power/cooling modules are externally
identical except the blower module includes none of the power
switch, connector, or LED components.

rating on the enclosure label. This rating is the maximum power
required for a fully loaded enclosure. The input current, power (VA),
and dissipation per enclosure are based on the maximum capability
of the power supplies and cooling system to provide internally
regulated power. Typical values will be less than the maximum,
depending on the number and manufacturer of disk drives. These
values represent the sum of values shared by the line cords of two
power supplies in the same enclosure. Power cords and supplies
share the power load evenly. If one of the two power supplies in a
standard CX200 fails, the remaining supply and cord support the full
load. You must use a rackmount cabinet with ac power distribution,
and have main branch ac distribution that can handle these values for
the number of components that you will interconnect.

temperature specification described in Appendix A. The site must
have air conditioning of the correct size and placement to maintain
the specified ambient temperature range. The air conditioning must
be able to handle the BTU requirements of the CX200-Series DPE2
and any additional disk enclosure.

Cabling Requirements

2-2

EMC CX200-Series DPE2 Hardware Reference

The CX200 DPE2 supports copper cable for back-end (BE) connections
to disks it controls (for example, DAE2 disk enclosures). CX200-Series
systems use optical cables for front-end (FE) connections to the
external Fibre Channel environment.

Any copper cables you use must meet the appropriate standards for
2-Gbit FC-AL. Such cables must be fully shielded, twin-axial,
full-duplex cables with High Speed Serial Data Connector (HSSDC)
connectors. Distances greater than 1 meter require equalized cables;
unequalized 1-meter cables are adequate. The DPE2 does not support
cables shorter than 1 meter or longer than 10 meters.

Installing a CX200-Series DPE2

EMC supports and can provide 1-, 5-, and 10-meter cables. The 5- and
10-meter cables are equalized.

Interconnections between the CX200 and a disk enclosure should
maintain consistency with the link controller cards (LCCs) in the
additional disk enclosure. For example, SP A interconnects with LCC
A, and SP B interconnects only to LCC B.

Do not leave an unused (that is dangling) cable connected to a host or
enclosure port because it may cause excess noise on the loop.

Addressing Requirements

Enclosure Address

(EA)

Disk Requirements

Addressing requirements vary between fibre port (fabric) and fibre
loop (FC-AL) environments.

Fabric environments use the Source_ID (SID) and enclosure address
(EA) to address each disk enclosure. A switch in the external Fibre
Channel environment automatically assigns the Source_ID.

FC-AL environments use the FC-AL address ID and the enclosure
address (EA) to address each enclosure.

Each CX200 DPE2 and DAE2 on a back-end loop needs a unique
enclosure address (EA) that identifies the enclosure and determines
disk module addresses.

The CX200-Series DPE2 has a fixed EA of 0, which you should not change.
The standard CX200 supports one Fibre Channel loop and a
maximum of two disk enclosures (including the CX200 DPE2 itself).
The CX200LC supports a single, non-redundant, integrated loop and
does not support a second disk enclosure. For ease of use, we
recommend that you keep the EAs sequential; a maximum
configuration would therefore include an EA 0 and an EA 1 for the
single CX200 loop (loop 0).

CX200 storage systems require at least five disk modules installed in
slots 0, 1, 2, 3, and 4 (the leftmost slots) of the DPE2. Full high
availability that includes write caching requires five disk modules
and an SPS unit. CX200LC storage systems do not support write
caching and require only three disk modules, in slots 0, 1, and 2. Disk
module IDs are numbered left to right (facing the unit) and are
contiguous throughout an array: enclosure 0 contains modules 0-14;
enclosure 1 contains modules 15-29.

Requirements

2-3

Installing a CX200-Series DPE2

The disk modules in slots 0-3 (CX200 enclosure) or 0-2 (CX200LC) provide
mirrored boot capability and are preloaded according to their slot assignment
before shipment. Do not move a preloaded module from its assigned slot to
another slot, and remove it only to replace the disk. For details on DAE2
disks and their configuration, refer to the EMC 2-Gigabit Disk Enclosure

(DAE2) Hardware Reference.

Installing a DPE2 in a Cabinet

CX200-Series DPE2s mount inside a cabinet on two L-shaped
mounting rails connected to the cabinet’s vertical channels. If you
need to install a cabinet or CX200-Series chassis, refer to one of the
following manuals:

◆ Installing the cabinet itself is explained in the cabinet installation

manual shipped with the cabinet.

◆ Installing the universal mounting rails in the cabinet, and

installing the 3U chassis on those rails, is explained in the EMC
Rails and Enclosures Installation Guide for 19-Inch NEMA Cabinets

that shipped with the rails.

Warnings and Recommendations:

2-4

EMC CX200-Series DPE2 Hardware Reference

The cabinet in which you will install the CX200 must have a full earth
ground to provide reliable grounding. Also, the cabinet should have
its own switchable power distribution. We suggest that you use a
cabinet that has dual power distribution units, one on each side.

WARNING

The enclosure is heavy and should be installed into a rack by two
people. To avoid personal injury and/or damage to the equipment, do
not attempt to lift and install the enclosure into a rack without a
mechanical lift and/or help from another person.

L’armoire étant lourde, sa mise en place sur une rampe nécessite deux
personnes. Afin de ne pas vous blesser et/ou endommager le matériel,
n’essayez pas de soulever et d’installer l’armoire sur une rampe sans
avoir recours à un relevage mécanique et/ou à l’aide d’une autre
personne.

Das Gehäuse ist schwer und sollte nur von zwei Personen in einem
Rack installiert werden. Zur Vermeidung von körperlichen
Verletzungen und/oder der Beschädigung des Gerätes, bitte das

Gehäuse nicht ohne die Hilfe einer zweiten Person anheben und
einbauen.

Il contenitore è pesante e dev'essere installato nel rack da due
persone. Per evitare danni personali e/o all’apparecchiatura, non
tentare di sollevare ed installare in un rack il contenitore senza un
sollevatore meccanico e/o l’aiuto di un’altra persona.

Debido a su considerable peso, la instalación del compartimento en
el bastidor deben realizarla siempre dos personas. Para evitar daños
personales o en el equipo, el compartimento no debe levantarse ni
instalarse en el bastidor sin la ayuda de un elevador mecánico o de
otra persona.

We recommend that you use cabinet anti-tip devices, especially if you
are installing or removing a storage system or disk enclosure in the
upper half of the cabinet when the lower half is empty.

Setting Up an Installed CX200-Series DPE2

Installing a CX200-Series DPE2

Setting Enclosure Addresses

!

CAUTION

Be sure the circuit breakers and any standby power supplies in
your cabinet are switched off before you begin setting up the
CX200 or CX200LC.

Each disk enclosure in your system must have a unique enclosure ID
(also called an enclosure address, or EA) that identifies the enclosure
and determines disk module IDs. In most cases, the enclosure
address has been set before shipment to coincide with the rest of the
system; you need to reset the switch if you installed the enclosure
into your rack independently. The EA can range from 0 through 7,
though we recommend that you number them consecutively from 0.
The CX200-Series DPE2 is always enclosure 0. An additional DAE2
disk enclosure is usually numbered 1, reflecting its position on the
Fibre Channel loop (bus) connecting the array. You set the EA with
the enclosure address switch, which has one push button for
incrementing the address and another for decrementing it. To set the
EA, you can use a pen, paper clip, or small screwdriver.

!

CAUTION

Each drive reads its FC-AL physical address only at powerup or
when the drive is reset. To avoid losing data, you must set the EA
when power is off; you cannot change the EA while power is on.

1. Set the enclosure address for the CX200/CX200LC to 0. Refer to
Figure 2-1.

2. Set the enclosure address for an additional disk enclosure (CX200

Connecting the CX200-Series DPE2 to the External Environment

When working with optical cables, observe the following
precautions:

◆ Keep the covers on all optical cables and optical connectors until

you are ready to insert the cables. The covers protect the cables
and connectors, and prevent foreign particles, such as dust, from
entering and affecting the connection.

◆ Do not leave any unused (dangling) cables connected to an SP

port.

◆ Avoid tight bends, particularly those 90º or more.

◆ Do not use optical cables to support weight, including long cable

runs without support.

◆ Do not pull long runs of cable. It is best to lay the cable in place or

pull only a few feet at a time.

◆ Run the cables so that they are not stepped on or rolled over by

anything.

For each SP connection to the external environment, attach an optical
cable from the front-end (FE) connector to the external environment.
Follow the steps below to cable and connect the SPs.

Installing a CX200-Series DPE2

1. Remove the protective covers from optical connector FE A and an
optical cable, as shown in Figure 2-8.

2. Plug the cable into the FE A connector on the SP. See Figure 2-8.

Do not use the FE B host connector, except for a direct connection to a
host bus adapter on a dual-node cluster.

Never connect both FE A and FE B to a switch.

Making Management LAN Connections

2-12

EMC CX200-Series DPE2 Hardware Reference

CX200-Series systems do not support MirrorView™ or SnapView™
software applications, external hubs, or daisy-chained arrays.

Before you connect your system to a management Local Area
Network, refer to the Navisphere 6.X Release Notes for the version of
the Java 2 Runtime Environment (JRE) and web browser (Internet
Explorer or Netscape) required to manage your system. With the
proper browser and JRE, you can manage a CX200 Series system from
any server that shares a LAN with your storage system’s domain.
(Note that Navisphere Manager is required on at least one system in
the domain.)

!

CAUTION

To manage the storage system in a NEBS (Network Equipment
Building System) environment, use either of the following
configurations:

◆ To connect a local client (a notebook or other server) to the SP

LAN ports, use short Ethernet cables and a simple Ethernet
hub.

◆ To connect the SP LAN ports to your intra-building network,

you must use shielded cable and grounded connectors at both
ends of the connection points.

Connect each SP to the LAN from which you will run Navisphere
management, as shown in Figure 2-9 or Figure 2-10.

DPE2 Powerup and Initialization

Before applying power to a storage system, make sure all the disk
module slots in each disk enclosure contain either disk or filler
modules, for proper cooling and normal operation.

Do not power up a disk enclosure without at least one SP or LCC installed.

To power up the CX200-Series system:

1. Turn on the power to any DAE2 connected to the CX200.

2. Turn the CX200/CX200LC power supply/cooling module
switches to the on (l) position.

3. If present (CX200 systems only), turn the SPS power switch to the
on position.

4. In the cabinet, set the main circuit breaker switches to the on
position.

The CX200/CX200LC and any connected DAE2 in the cabinet
will power up.

2-14

The only power switches on a DPE2 or DAE2 disk enclosure are those on the
power supply, which are normally on. As a result, the units are always active.

When you initially apply ac power to a disk enclosure, the disk drives
power up according to their specifications, and spin up in a specified
sequence dictated by enclosure and loop id. The slot spin-up delays
range from 0 to 84 seconds. The slots use the same delays when you
insert a drive while the system is powered up.

The CX200-Series hardware monitor (FRU monitor) resets and begins
its control loop. The port bypass circuits enter the states indicated by
their associated drives. The monitor continues to run in this local
mode until it receives commands that dictate otherwise. In local
mode, the monitor maintains the port bypass circuits in the same
states as the drive command signals. When a drive fault occurs, the
corresponding drive fault light turns on. Firmware commands can
take control of the port bypass circuits and the drive status lights.

EMC CX200-Series DPE2 Hardware Reference

Installing a CX200-Series DPE2

!

CAUTION

The drives read their FC-AL physical address only at powerup or
when the drive is reset. To avoid potential data loss, you must set
the enclosure address when you install the disk enclosure and
power is off; you cannot change the EA while power is on.

For instructions on how to initialize your system after its first
powerup, refer to the EMC Storage Systems CX200-Series Initialization

Guide and the EMC Installation Roadmap for CX-Series and FC-Series
Storage Systems.

CX200-Series Powerdown

If a CX200 with an SPS is powered down abnormally (for example, a
brownout or ac failure), cached data is saved to the storage-system
vault disks. However, when the CX200 is powered back up again, it
may take longer to come on line.

Turning Off the Power

1. Stop all I/O activity to the DPE2.

Stopping the I/O allows the SP in a CX200 DPE2 to transfer cache data,
and may take some time. The length of time will be based on criteria such
as the amount of cache, the amount of data in the cache, the type of data
in the cache, and the target location on the disks, but it is typically less
than one minute. CX200LC systems do not support write-caching.

2. If the server connected to the CX200/CX200LC is running the
UNIX® operating system, unmount file systems.

3. Use the power switch on an SPS to turn off power to the CX200
DPE2 and any other device connected to the SPS. If the
power/cooling module is not connected to an SPS, turn off power
with the power/cooling module power switch. See Figure 2-11.

you should replace that FRU as soon as possible.

Handling FRUs

Power Issues and FRUs

When a redundant FRU fails, high availability is compromised until you
replace the faulty FRU.

This section describes the precautions that you must take and the
general procedures you must follow when removing, installing, and
storing FRUs.

The CX200-Series DPE2 is designed to always be powered up and to
be hot repairable. Its front bezel should be attached and each of its
compartments should contain a FRU or filler panel to ensure EMI
compliance and proper air flow over the FRUs.

While the CX200 is powered up, you can service or replace any FRU,
although removing an active SP will affect operating system access to

Handling FRUs

3-5

Servicing and Upgrading a CX200-Series DPE2

the disks it controls. You should not remove a faulty FRU until you
have a replacement available.

Since you can replace or add any FRU without sliding the enclosure
out of the cabinet, you do not have to use cabinet anti-tip devices
when you upgrade or service a CX200-Series DPE2.

If you need to power down a CX200-Series system, first shut down
the storage processors (refer to your Navisphere Manager
Administrator’s Guide), and then shut off power to the SPS, if you
have one. Shut off power to the power/cooling module(s) with the
power switch. You do not need to shut down main ac lines to the disk
enclosure unless you need to power down all the cabinet contents
connected to that line.

Avoiding Electrostatic Discharge (ESD) Damage

!

CAUTION

Never shut off the power supplies to shut down a CX200 power
supply that is connected to an SPS. Bypassing the SPS in that
manner prevents the system from saving write cache data to the
vault drives, and results in data loss. You will lose access to data,
and the storage processor event log will display an error message
similar to the following:

Enclosure 0 Disk 5 0x90a (Can’t Assign - Cache Dirty) 0
0xafb40 0x14362c

.

Contact your service provider if this situation occurs.

When you replace or install FRUs, you can inadvertently damage the
sensitive electronic circuits in the equipment by simply touching
them. Electrostatic charge that has accumulated on your body
discharges through the circuits. If the air in the work area is very dry,
running a humidifier in the work area will help decrease the risk of
ESD damage. You must follow the procedures below to prevent
damage to the equipment.

Read and understand the following instructions:

◆ Provide enough room to work on the equipment. Clear the work

site of any unnecessary materials or materials that naturally build
up electrostatic charge, such as foam packaging, foam cups,
cellophane wrappers, and similar items.

3-6

EMC CX200-Series DPE2 Hardware Reference

Servicing and Upgrading a CX200-Series DPE2

◆ Do not remove replacement or upgrade FRUs from their antistatic

packaging until you are ready to install them.

◆ Gather together the ESD kit and all other materials you will need

before you service an enclosure. Once servicing begins, you
should avoid moving away from the work site; otherwise, you
may build up an electrostatic charge.

◆ Use the ESD kit when handling any FRU. If an emergency arises

and the ESD kit is not available, follow the procedures in the
Emergency Procedures (Without an ESD Kit) section.

◆ An ESD wristband is supplied with your storage system. To use

it, attach the clip of the ESD wristband (strap) to any bare
(unpainted) metal on the enclosure; then put the wristband
around your wrist with the metal button against your skin.

Emergency Procedures (Without an ESD Kit)

In an emergency when an ESD kit is not available, use the following
procedures to reduce the possibility of an electrostatic discharge by
ensuring that your body and the subassembly are at the same
electrostatic potential.

These procedures are not a substitute for the use of an ESD kit.
Follow them only in the event of an emergency.

◆ Before touching any FRU, touch a bare (unpainted) metal surface

of the cabinet or enclosure.

◆ Before removing any FRU from its antistatic bag, place one hand

firmly on a bare metal surface of the enclosure, and at the same
time, pick up the FRU while it is still sealed in the antistatic bag.
Once you have done this, do not move around the room or contact
other furnishings, personnel, or surfaces until you have installed
the FRU.

◆ When you remove a FRU from the antistatic bag, avoid touching

any electronic components and circuits on it.

◆ If you must move around the room or touch other surfaces before

Servicing and Upgrading a CX200-Series DPE2

Precautions When Removing, Installing, or Storing FRUs

Use the precautions listed below when you remove, handle, or store
FRUs.

◆ Do not remove a faulty FRU until you have a replacement

available.

◆ Handle a FRU only when using an ESD wristband as follows:

attach the clip of the ESD wristband to the ESD bracket or bare
metal on the enclosure, and put the wristband around your wrist
with the metal button against your skin.

◆ Handle FRUs gently. A sudden jar, drop, or vibration can

permanently damage a FRU and may not be immediately
evident. Never place a FRU on a hard surface such as an
unpadded cart, floor, or desktop, or stacked on top of another
FRU.

◆ Never use excessive force to remove or install a FRU.

◆ Store a FRU in the antistatic bag and specially designed shipping

container in which you received it. Use that container if you need
to return the FRU for repair.

◆ Store FRUs in a location that is within the limits specified in

Appendix A.

◆ Place the cables where no one can step on them or roll equipment

over them.

Replacing or Adding a Disk Module

Servicing and Upgrading a CX200-Series DPE2

!

CAUTION

Disk modules are extremely sensitive electronic components.
Always handle a disk module gently, and observe the following
guidelines:

◆ Follow the instructions in the preceding section Avoiding

Electrostatic Discharge (ESD) Damage on page 3-6.

◆ Always wear a properly attached ESD wristband when

removing or replacing a disk module.

◆ When removing a disk module, pull the module partially out of

the slot, then wait 30 seconds for the drive to spin down before
removing it.

◆ Place modules on a soft, antistatic surface, such as an

industry-standard antistatic foam pad or the container used to
ship the module. Never place a disk module directly on a hard
surface.

◆ Never hit modules, stack modules, or allow them to tip over or

fall.

◆ Avoid touching any exposed electronic components and circuits

on the disk module.

◆ Do not remove a faulty disk module until you have a

replacement module (with the same part number) or a filler
module available. The part number (PN005xxxxxx) appears on
the top or bottom of the module. A replacement or add-on disk
module should have the same format (bytes per sector) and the
same capacity (size and speed) as the other modules in the
enclosure.

◆ Before adding more disks to your DPE2, refer to the EMC

Storage Systems CX200-Series Configuration Planning Guide,

which contains guidelines for creating RAID groups with disks
of varying sizes and speeds.

You must remove the DPE2 front bezel to gain access to the disk
modules. The bezel is required for EMI compliance when the
enclosure is powered up. Remove it only to replace or add a disk
module.

CAUTION

If a disk module has been bound into a LUN, do not move it to
another slot unless you do not care about the data on the LUN. Each
module has LUN-identifying information written when it is
bound. Moving it to another slot can make information on the
original LUN inaccessible.

The disk modules in slots 0-3 (CX200 enclosure) or 0-2 (CX200LC)
provide mirrored boot capability and are preloaded according to
their slot assignment before shipment. Do not move a preloaded
module from its assigned slot to another slot, and remove it only to
replace the disk.

Replacing a Power Supply/System Cooling Module

This section explains how to replace a power supply/system cooling
module, and a CX200LC blower module.

!

Removing a Power Supply/System Cooling Module

CAUTION

Handle the modules gently and use an ESD wristband. Do not
remove a power/cooling or blower module until you have a
replacement module available.

If one power supply is off and the other is on, do not turn one on
and immediately turn off the other. Instead, turn one on and wait
five seconds after the green LED lights before turning the other off.

Turn off the power supply before unplugging the power cord from
a module or cabinet power strip.

Access to the disks in your enclosure will time out two minutes after
you remove a power supply/system cooling module or a blower
module from the system. While the system can continue operating on
a single power supply, the loss of a module’s two blowers will cause a
time-out unless you replace the module within two minutes.

Follow these steps to replace a power supply/system cooling module
or a blower module.

1. If you are replacing a power/cooling module, turn off the power
supply and unplug its ac line cord. Figure 3-13 shows the power
switch and line cord location on a CX200.

The Standby Power

Supply (SPS)

The standby power supply (SPS) provides backup power required to
protect the integrity of the CX200’s storage processor write cache.
This chapter describes the CX200 SPS and how to determine SPS
status.

For instructions on installing or replacing an SPS, refer to the EMC
Rails and Enclosures Installation Guide for 19-Inch NEMA Cabinets.

IMPORTANT: The SPS is intended to provide backup power for DAE2 and
CX-Series enclosures only.

CX200LC systems do not include an SPS, and do not support write-caching.

The Standby Power Supply (SPS)

4-1

The Standby Power Supply (SPS)

About the SPS

A 1000-watt dc SPS can provide backup power for one CX200 power
supply and storage processor. The SPS provides higher availability
and allows write caching — which prevents data loss during a power
failure — to continue. A faulted or not fully charged SPS disables
write caching.

The SPS rear panel has one ac inlet power connector with a power
switch, an ac outlet for the CX200, another ac outlet which you
should not use in CX200 configurations, one data connector to the
storage processor, and status lights.

IMPORTANT: Improper storage and handling of an SPS will render the
warranty null and void. Please see Appendix A for appropriate SPS storage
requirements.

Figure 4-1 shows the SPS unit, removed from its cabinet mounting.

SPS fault - Amber The SPS has an internal fault. The SPS may still be able

to run on line, but write caching cannot occur. Replace
the SPS as soon as possible.

Replace battery - Amber The SPS battery pack can no longer support loads.

When the battery reaches this state, and no other on-line
SPS is connected to the CX200, the processor flushes all
cache data to disk and disables caching. This LED stays
active until the SPS completes a successful power test.
Replace the SPS as soon as possible.

On battery - Amber The ac line power is no longer available and the SPS is

supplying dc output power from its battery. When battery
power comes on, and no other on-line SPS is connected
to the CX200, the processor writes all cached data to
disk; and the event log records the event.

Active - Green When this LED is steady, the SPS is ready and operating

normally. When this LED blinks, the SPS is charging. In
either case, ac line input supplies the output from the
SPS.

EMC2475

In the event of a power failure, an SPS provides backup power until
the storage processor has flushed its write cache data to the CX200
disks. The storage processor then shuts the SPS power off. If the cache
flush has not completed within 60 seconds — more than enough time
to flush a full cache — or if the storage processor has failed, then the
SPS shuts itself down to prevent deep discharge. If there is no ac inlet
power and the SPS is shut down, all status lights will be off.

4-4

When power returns, the SPS starts recharging. It may reach a state of
full charge relatively quickly. If power remains off for a long period
— days or weeks — the battery may require more time to charge
fully. The storage processor will not use the write cache unless it
detects a fully charged SPS.

Battery lifetime depends on the number of discharge cycles and
depth of discharge. In a typical environment, a battery pack can last 3
to 5 years. Battery pack lifetime is shorter in locations that have
frequent ac outages.

CX200-Series DPE2 Technical Specifications

Technical specifications include power requirements, size, drive,
interface, and standards information.

ac Power Requirements

The input current, power (VA), and dissipation per DPE2 are based
on the maximum capability of the power supplies and cooling system
to provide internal regulated power. Typical values will be less,
depending on the number and manufacturer of disk modules. These
values represent either

◆ the values for a single power supply line cord, or

◆ the sum of the values shared by the line cords of two power

supplies in the same enclosure, with the division between the line
cords and supplies at the current sharing ratio (approximately
50% each).

A failure of one of the two power supplies in the DPE2 results in the
remaining supply and cord supporting the full load. You must use a
rackmount cabinet with ac power distribution, and have main branch
ac distribution that can handle these values for each CX200 in the
cabinet.

Battery Tests

Battery Self-Discharge Times

When you store an SPS, the battery charge level naturally decreases
over time. This is characteristic of all rechargeable batteries. The rate
of self-discharge depends on temperature. Lower storage
temperatures are desirable since the self-discharge rate is lower. The
following graph shows how the remaining charge decreases over
time at different temperatures.

Technical Specifications and Operating Limits

Internal Within 60 minutes after powerup and approximately every 2 weeks

thereafter, the SPS itself performs a light test on the batteries. This test lasts
less than one second. It does not verify battery capacity but does check
connectivity and functionality. This test is transparent to other components in
the array. If an actual power failure occurs during the test, the test is
terminated and the unit goes into On-Battery mode.

Full At each storage-system startup, the system software initiates a full power

test. During the test, the system disables write cache and allows the SPS to
stay on for a full 90 seconds.

The system initiates a full test when the SPS is online and fully charged. If
the batteries are charging at test time, the system defers the test until the
next programmed time.

IMPORTANT: If you are storing an SPS, do not store it longer than 6 months
or at a temperature exceeding 30° C without recharging it. When you retrieve
an SPS unit from storage, you should charge it by connecting it to ac power,
with its power switch in the on position, for at least 12 hours before putting it
into service or returning it to storage.

A storage device that includes an enclosure, disk modules, Fibre
Channel storage processors, power supplies, and cooling modules.

E

A number, selectable on a CX200 or DAE2 rear panel — fixed at 0 on a
DPE2 — that helps establish a unique address for each disk module
on an FC-AL loop. You must set the EA on each DAE2. Since the
CX200 EA is 0, you should set the DAE2 EA on the single loop (0) to

Electronic radiation emitted by an electrical device. The levels of EMI
are strictly controlled for data processing equipment. The EMI
standards to which the CX200-Series complies are listed in
Appendix A of this manual.

The discharge of an accumulated electrical charge (static). This can
severely damage delicate electronic circuits so you should take steps
to prevent this, as explained in Chapter 3, Servicing and Upgrading a
CX200-Series DPE2.

F

a failure occurs in the path of the original SP.

An arrangement of Fibre Channel stations such that messages pass
from one to the next in a ring.

The name for the printed-circuit board within the computer chassis
through which the server gains access to the Fibre Channel loop and
thus the SP(s).

See FRU (field-replaceable unit).

optical, and vice versa.

H

Another name for Fibre Channel adapter.

such as storage systems to connect at a central point. A single hub
configuration appears as a single loop.

L

A FRU in DAE2 enclosures, integrated into the SP module in a
CX200-Series DPE2. An LCC connects Fibre Channel signalling to the
disk modules, and provides Fibre Channel connectivity between the
SP, disks, and other enclosures. It also provides bypass capability for
faulted or missing units, and monitors and controls enclosure
elements.

LUN (logical unit) One or more disk modules (each having a head assembly and

spindle) bound into a group — usually a RAID group. The operating
system sees the LUN, which includes one or more disk modules, as
one contiguous span of disk space.

M

memory module See SP memory module.

N

node Any device with a Fibre Channel interface (such as an HBA in a

server or a storage system’s SP) that connects to a Fibre Channel loop.

SCSI (small computer

system interface)

A device for the distribution of ac line power from one inlet to

source, if the PDUs use separate ac sources) loses power.

system components. A storage system can have two power supplies,
PS A and PS B. With two, it can survive failure of one supply. You can
replace one of two power supplies under power, without interrupting
applications.

R

The storage system provides replace under power capability that
allows you to replace a FRU (for example, a disk module or a fan
module) without powering down the storage system. Applications
continue while you replace the failed module.

S

A well-known protocol and standard for connecting computers and
peripheral devices. Some Fibre Channel SPs use a Fibre Channel
FC-AL front end to the server and a SCSI back end to the disk
modules. The SPs used in DPEs use the Fibre Channel protocol
throughout. The array uses SCSI protocol over Fibre Channel.

server In the context of storage systems, a processor that runs an operating

system and uses a disk-array storage system for data storage and
retrieval.

SP (storage

SPS (standby power

supply)

EMC CX200-Series DPE2 Hardware Reference

A printed-circuit board with processor memory modules and control
logic that manages the storage-system I/O between the server FC
adapter and the disk modules.

A memory module that provides the local storage for an SP.

A unit that provides temporary backup power in case of a power
outage. An SPS is required for storage-system write caching. If power
fails, the SPS allows the SP to write the data from its cache to disk.
