system. You can find Celerra manuals on the EMC PowerLink
website http://powerlink.emc.com. Once logged in to Powerlink,
select Products > Networked Storage> Network Attached Storage
(NAS) > Celerra Systems > Celerra Manuals, Product Guides,
Configuration Guides, etc.
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 your facility has appropriate electrical wiring in
place to accommodate your cabinet’s power cables.
The standard 40U EMC cabinet includes two 240-volt ac power
cables. To support all DAE2 high-availability features, you must
connect each power outlet to a different circuit.
2. If you will connect the DAE2 to a storage device such as a CX-Series
storage processor enclosure (SPE) or disk processor enclosure
(DPE2), 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 Navisphere Manager to monitor DAE2 status,
make sure that Navisphere Manager version 6.1 or higher is set up.
Refer to the EMC Navisphere Manager Version 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 Rails and Enclosures Installation Guide for 19-inch NEMA Cabinets
describes how to install a 3U device like the DAE2 in EMC’s standard
cabinet.
You can add DAE2 enclosures to active storage systems without
powering down the existing system.
Step 1
Set DAE2 Enclosure Address(es)
Set the enclosure address (EA) on each DAE2 in a given loop to a unique
number. We strongly suggest that you number enclosures consecutively. Refer
also to the illustrations in Step 2.
NOTE Do not configure an ATA model DAE2 as EA 0, loop 0. ATA
enclosures do not support the boot and SPS requirements of the first disk
array in a storage system.
An integrated disk-and-processor enclosure, such as a DPE2, is always the
first disk enclosure on the first loop (0,0).
Step 2
Set Up Fibre Channel Loops
Connect multiple DAE2s in paired loops. (A Fibre Channel loop is sometimes
called a bus.) One loop connects the SP A/LCC A (right) side of the system;
the SP B/LCC B loop shares disk drives with its counterpart.
Cable the expansion connector (EXP) of a 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
processor.
The first configuration on the right shows two redundant DAE2 loops
connected to a 2-Gigabit Disk Processor Enclosure (DPE2).
The illustration below shows an example storage-system configuration with
four pairs of redundant DAE2 loops: A0/B0, A1/B1, A2/B2, A3/B3.

Step 3
Connect the DAE2 to a
Storage Processing Device
If you are connecting the first DAE2 in a loop to a storage processing device,
such as an SPE or DPE2:
1. 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.
2. Plug the other end of the cables into the appropriate connector on the
storage processor device. For more information, refer to the Setup
Guide or the Hardware Reference for the device.
Step 4
Connect DAE2 Power Cords
1. Connect one end of an ac power cable to the power connector on
each DAE2 power supply.
2. Connect the other end 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.
In the CX600/CX700 SPE example above, the first DAE2 is connected to a
secondary power supply (SPS). In DPE2 configurations, you should not connect a
DAE2 to the SPS. Refer to the relevant Setup Guide or Hardware Reference for
device-specific configuration rules.
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. You must connect both power cables to the appropriate
power source. 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, available on Powerlink and the DAE2 Hardware
Documentation CD. If you cannot determine any reasons for errors, contact
your DAE2 service provider.
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
Navisphere Manager Version 6.X Administrator’s Guide or the appropriate
checklist in the EMC Installation Roadmap (P/N 069001166).
The Installation Roadmap and other EMC CLARiiON® storage system setup
and administration manuals are available on http://powerlink.emc.com. Once
logged in to Powerlink, select Support > Document Library to find the
documentation you need.
These resources are available in case you encounter problems while setting up
or using the DAE2.
