About This Guide

This guide outlines the steps you must follow and the information you
will need to get one or more 2-Gigabit Disk Array Enclosures (DAE2s)
up and running. It assumes you are configuring the 3U enclosure as a
disk array for a storage processing device (such as an EMC SPE with
storage processors). Refer to this guide as you perform the following
tasks:

• Set DAE2 Enclosure Address(es)

• Set Up Fibre Channel Loops

• Connect the DAE2 to a Storage Processing Device

• Connect DAE2 Power Cords

• Start DAE2s

IMPORTANT The section called Your Next Step, that starts on
page 10 of this guide, lists and describes additional resources you
might need to solve typical installation and operating problems.

For information on JBOD (Just a Bunch of Disks) or other non-array
configurations, please contact your sales representative

This guide refers to various documents that provide detailed
descriptions of each step. The most current versions of DAE2
documentation are available on the EMC Powerlink website,

http://powerlink.emc.com

Services, then Document Library, CLARiiON, CLARiiON Fibre
Channel Storage (FC) and then CLARiiON FC Hardware,
CLARiiON FC Core Software, or CLARiiON FC Software for lists

and .pdf versions of relevant manuals, notes, and articles.

Parts Checklist for Basic Configuration

Before you start, be sure you have the necessary materials available.
Most required parts were provided with your system, but some are
shipped with particular components (and configurations) and others
are shipped separately.

❑ One or more DAE2 disk enclosures
❑ EMC-approved disk drives

For a list of supported RAID disks, refer to the EMC Storage Systems
CX-Series Disk and Software Matrix (P/N 014003111), available on the

Powerlink website.

❑ If your DAE2 is not already installed in a rackmount cabinet

❑ One or more rails kits, and the

❑ EMC Storage Systems 40U Cabinet Configuration Guide

(P/N 014003082)

❑ Fibre Channel copper cable for connecting the DAE2 to a storage

processor device (1 per connection)

❑ Copper cables for connecting multiple DAE2s to each other

(2 per DAE2)

Before You Start

IMPORTANT Be sure you have completed all of the following site
and configuration preparations before you attempt to set up your
DAE2s.

1. Confirm that electrical wiring to accommodate your cabinet’s
power cables is in place at your facility.

The standard 40U EMC cabinet includes two 240-volt ac power cables.
To support all of the DAE2 high-availability features, you must connect
each power outlet to a different circuit.

2. If you are connecting the DAE2 to a storage device such as a
CX-Series storage processor enclosure (SPE), make sure the
device is installed in the cabinet and set up. Refer to the Setup
Guide or Hardware Reference for the device.

3. If you will use EMC ControlCenter Navisphere Manager to
monitor DAE2 status, make sure that Navisphere Manager
version 6.1 or higher is set up. Refer to the EMC ControlCenter
Navisphere Manager Revision 6.X Administrator’s Guide and the
appropriate Release Notes as necessary.

4. If your DAE2 is not already installed in a cabinet, do so now. The

EMC Storage Systems 40U Cabinet Configuration Guide

describes how to install a 3U device like the DAE2 in EMC’s
standard cabinet.

You can add DAE2 enclosures to running storage systems without
powering down the existing system.

Set the enclosure address on each DAE2 in a given loop to a unique number.
We strongly suggest that you number enclosures consecutively. Refer also to
the illustrations on page 5 and page 6.

Step 2

Set Up Fibre Channel Loops

Connect multiple DAE2s in loops.

NOTE A Fibre Channel loop is sometimes called a bus.

Cable the expansion connector (EXP) of one DAE2 to the primary connector
(PRI) of the next DAE2 you want on the loop.

The primary connector of the first DAE2 in the loop is reserved for the storage
device.

Refer to the illustrations on page 5 and page 6.

1. If you are connecting the first DAE2 in a loop to a storage
processing device

a. Plug one end of a copper cable into the primary (PRI) High Speed

Serial Data Connector (HSSDC) connector on each Link Control
Card (LCC) in the DAE2.

b. Plug the other end of the cables into the appropriate connector on

the storage device. Refer to the Setup Guide or the Hardware
Reference for the device.

1. Connect one end of an ac power cable to the power connector on
each DAE2 power supply.

2. Connect the other end of each ac power cable to the nearest
power outlet in the cabinet. For high availability, connect the
power supplies to opposing side power strips so they do not share
a single circuit.

The highly available configuration example shown above supports write
caching. It has two power strips and an SPE, and the first DAE2 is
connected to a secondary power supply (SPS).

Step 5

Start DAE2s

1. Turn on the power for each DAE2 power supply.

2. If the cabinet power is not already on, be sure the other devices
in the system are correctly installed and ready for powerup, then

a. Plug the two 240-volt ac power cables into the power outlets in your

facility. We recommend connecting each power cable to a different
branch circuit. Both power cables must be connected to the
appropriate power supply. Connecting only one power source will
degrade the DAE2’s performance.

b. Turn on the circuit breakers on each of the cabinet’s side power

strips.

The green power lights on the front of the DAE2 chassis and on each disk
drive indicate that power is on; an amber chassis light indicates a fault.

If an amber light on the front of a DAE2 is lit, make sure the DAE2 is
correctly cabled, the enclosure addresses are correct, and the disks are
completely seated. Then refer to the fault code explanations in Chapter 3 of
the DAE2 Hardware Reference. If you cannot determine any reasons for
errors, contact your DAE2 service provider. (If you have an EMC service
contract, contact EMC Customer Service at USA [phone],
Canada [phone], or worldwide [phone].)

Your Next Step

Once your DAE2 is up and running, you can integrate the DAE2 into
your existing storage system, or initialize a new system. Refer to the

EMC ControlCenter Navisphere Manager Version 6.X Administrator’s
Guide or the appropriate checklist in the EMC Installation Roadmap.
