The following warnings and cautions pertain throughout this guide.
WARNING Trained service personnel only
Ground circuit continuity is vital for safe operation of the machine.
Never operate the machine with grounding conductors disconnected.
Remember to reconnect any grounding conductors removed for or
during any installation procedure.
ATTENTION Resérvé au personnel autorisé.
Un circuit de terre continu est essentiel en vue du fonctionnement
sécuritaire de l'apareil. Ne jamais mettre l'appareil en marche lorsque
le conducteur de mise a la terre est débranché.
WARNUNG Nur für Fachpersonal.
STROMSTREUVERLUST: Gerät muss geerdet werden, bevor es am
Stromnetz angeschlossen wird.

Warnings and Cautions
WARNING
Trained personnel are advised to exercise great care at all times
when working on the unit. Remember to:
◆ Remove rings, watches, or other jewelry and neckties before
you begin any procedures.
◆ Use caution near any moving part and any part that may start
unexpectedly such as fans, motors, solenoids, and so on.
◆ Always use the correct tools for the job.
◆ Always use the correct replacement parts.
◆ Keep all paperwork, including incident reports, up to date,
complete, and accurate.
Static precautions EMC incorporates state-of-the-art technology in its designs, including
the use of LSI and VLSI components. These chips are very susceptible
to damage caused by static discharge and need to be handled
accordingly.
CAUTION
!
Before handling printed-circuit boards or other parts containing
LSI and/or VLSI components, observe the following precautions:
◆ Store all printed-circuit boards in antistatic bags.
◆ Use a ground strap whenever you handle a printed-circuit
board.
◆ Unless specifically designed for nondisruptive replacement,
never plug or unplug printed-circuit boards with the power on.
Severe component damage may result.

Warnings and Cautions
Replacing the SP battery
A lithium battery on the storage processor powers the real-time clock
(RTC) for three to four years in the absence of power. Only trained
personnel should change or replace this battery.
WARNING
Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the equipment
manufacturer. Discard used batteries according to manufacturer's
instructions.

About DAE2P and DAE3P disk enclosures
Introduction
EMC® CLARiiON® DAE2P and DAE3P UltraPoint™ (sometimes
called "point-to-point") disk-array enclosures are highly available,
high-performance, high-capacity storage systems that use a Fibre
Channel Arbitrated Loop (FC-AL) as the interconnect interface. An
enclosure connects to another DAE or a CX-series processor, and is
managed by storage-system software in RAID (Redundant Array of
Independent Disk) configurations. The enclosure is only 3U (5.25
inches) high, but can include 15 hard disk drive/carrier modules. Its
modular, scalable design allows for additional disk storage as your
needs increase. The examples and illustrations in this manual show
the rackmounted DAE2P/DAE3P in a standard 40U EMC cabinet.
DAE2P enclosures include high-performance Fibre Channel disk
drives. DAE3P enclosures can include either Fibre Channel or
economical Serial Advanced Technology Attach (SATA 3 Gb/s,
sometimes called SATA II) drives. You can integrate and connect Fibre
Channel and SATA enclosures within a storage system, but you
cannot mix SATA and Fibre Channel components within a DAE3P.

About DAE2P and DAE3P disk enclosures
The DAE2P/DAE3P uses FC-AL link control cards to manage disks
and I/O traffic between enclosures. A DAE2P supports 2- or 4-gigabit
disks and 2-gigabit data transfer to and from disks on a Fibre Channel
loop called a back-end bus. DAE3P enclosures can support 2- or
4-gigabit disk modules and operate at either 2- or 4-gigabit bus speed.
2 Gb processors, enclosures, and disk modules cannot support or operate on
a 4 Gb bus. The DAE2P and DAE3P are externally identical except for
a distinguishing "4GB" label on the back of DAE3P enclosures.
Any DAE2P or DAE3P includes up to fifteen 3.5-inch disk modules.
Simple serial cabling provides easy scalability. You can interconnect
disk enclosures to form a large disk storage system; the number and
size of buses depends on the capabilities of your storage processor.
Highly available configurations require at least one pair of physically
independent loops (A and B sides of bus 0, sharing the same
dual-port disks). Other configurations use two, three, four, or more
buses. You can place the disk enclosures in the same cabinet, or in one
or more separate cabinets. High-availability features are standard.
The DAE2P/DAE3P includes the following components:
◆ A sheet-metal enclosure with a midplane and front bezel
◆ Two link control cards (LCCs)
◆ As many as 15 disk modules
◆ Two power supply/system cooling modules
The power supply and system cooling components of the power/cooling
modules function independently of each other, but the assemblies are
packaged together into a single field-replaceable unit (FRU).
Any unoccupied disk module slot has a filler module to maintain air
flow.
The LCCs, disk modules, power supply/system cooling modules,
and filler modules are field-replaceable units (FRUs), which you can
add or replace without tools while the array is powered up.
The enclosure can continue running with one operating power
supply and a single functional LCC. At least three of the four system
cooling blowers must be running correctly for continuous operation.
Figures 1-2 through1-4 show the disk enclosure components. Details
on each component accompany the figures. 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.

About DAE2P and DAE3P disk enclosures
For increased clarity, the following figures depict the disk enclosure outside
of the rack cabinet. Your disk 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
enclosure status lights are visible with the front bezel installed.
Figure 1-2 DAE2P/DAE3P front LED display
A blue power LED indicates a DAE3P enclosure operating at four
gigabits per second. The power LED is green in DAE2P enclosures,
and DAE3Ps operating at two Gb.
Figure 1-3 and Figure 1-4 show the DAE2P/DAE3P components
visible from the rear of the enclosure. Each highly-available enclosure
includes two link control cards and two power supply/system
cooling (power/cooling) modules.

As shown in Figure 1-5, an enclosure address (EA) indicator is
located on each LCC. (The EA is sometimes referred to as an
enclosure ID.) Each link control card (LCC) includes a bus (loop)
identification indicator. The storage processor initializes bus ID when
the operating system loads.

About DAE2P and DAE3P disk enclosures
Figure 1-5 Disk enclosure bus and address indicators
The enclosure address is set at installation. Disk module IDs are numbered
left to right (looking at the front of the unit) and are contiguous throughout
an array: enclosure 0 contains modules 0-14; enclosure 1 contains modules
15-29; enclosure 2 includes 30-44, and so on through eight enclosures.
The enclosure EA switch and bus indicator are described in the
installation procedure in Chapter 2. The status lights are described in
the “Monitoring disk enclosure status” section of Chapter 3.
Midplane
A midplane between the disk modules and the LCC and
power/cooling modules distributes power and signals to all
components in the enclosure. LCCs, power/cooling modules, and
disk drives — the enclosure’s field-replaceable units (FRUs) — plug
directly into the midplane.
Front bezel
The front bezel, shown in Figure 1-6, has a locking latch and an
electromagnetic interference (EMI) shield. You must remove the bezel
