BEFORE YOU START
IMPORTANT Be sure you have completed all of the following site
and configuration preparations before you attempt to set up your
DAE2Ps.
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 DAE2P high-availability features, you must
connect each power outlet to a different circuit.
2. If you will connect the DAE2P to a storage device such as a CX-Series
storage processor enclosure (SPE) or 2-gigabit 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 DAE2P status,
make sure that Navisphere Manager version 6.19 or higher is set up.
Refer to the EMC Navisphere Manager Administrator’s Guide and the
appropriate release notes as necessary.
4. If your DAE2P is not already installed in a cabinet, do so now. The
EMC Rails and Enclosures CX-Series Systems Field Installation Guide
describes how to install a 3U device like the DAE2P in a standard
19-inch NEMA cabinet.
You can add DAE2P enclosures to active storage systems without
powering down the existing system.
Step 1
Connect DAE2P Power Cords
1. Connect one end of an ac power cable to the power connector on
each DAE2P 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 CX700 SPE example above, the first DAE2P is connected to a standby
power supply (SPS). In DPE2 configurations, you should not connect a DAE2P to
the SPS. Refer to the relevant setup guide or hardware reference for device-
specific configuration rules.
Step 2
Start DAE2Ps
If the cabinet power is not already on, be sure the other devices in the system
are correctly installed and ready for powerup; then
1. 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 storage system’s performance.
2. Turn on the master switch (or main circuit breaker switch) for each of
the cabinet’s side power strips. In most cabinets, the switches are
located on the power distribution panel (PDP) or power distribution
unit (PDU).
The green power lights on the front of the DAE2P 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 DAE2P is lit, make sure the disks are
completely seated. Then refer to the fault code explanations in Chapter 3 of
the DAE2P Hardware Reference, available on the Powerlink website and the
Documentation CD. If you cannot determine any reasons for errors, contact
your DAE2P service provider.
Step 3
Set DAE2P Enclosure Address(es)
Blue LEDs on the back of the DAE2P indicate the enclosure address (EA). Each
disk enclosure (DPE2, DAE2, or DAE2P) in a given back-end loop (bus) requires a
unique number; we strongly suggest that you number enclosures
consecutively.
NOTE An integrated disk-and-processor enclosure, such as a DPE2, is
always the first disk enclosure on the first loop (0,0).
Unless integrated in a storage system, the DAE2P ships with a default EA. To
increment the EA, press the EA switch button on either link control card with a
tool such as a pen, paper clip, or small screwdriver. If this will be the first
enclosure on a loop, set the EA to 0. If you are adding the DAE2P to a
populated loop, change the EA to the next available address.
You must set the enclosure address when power is on and the enclosure is not
yet connected to a back-end loop. Illustrations on the next page show typical
loop/address configurations.

Step 4
Set Up Back-End Loops
Connect multiple DAEs (DAE2s or DAE2Ps) in paired loops. (A pair of Fibre
Channel loops is sometimes called a bus.) One loop connects the storage
processor (SP) A with link control cards (LCC) on the A (right) side of the
system; it shares disk drives with a counterpart SP B/LCC B loop.
Cable the expansion connector (EXP) of a DAE to the primary connector (PRI)
of the next DAE you want on the loop.
The primary connector of the first DAE in the loop is reserved for the storage
processor.
The configuration below shows two redundant DAE2P loops connected to a
DPE2.
The next illustration shows an example of a storage-system configuration with
four pairs of redundant DAE2P loops: A0/B0, A1/B1, A2/B2, A3/B3.
Always distribute enclosures as evenly as possible across every available
loop. You can mix DAE2 and DAE2P enclosures in the same storage
system; they should share a loop only to balance the configuration.
Step 5
Connect the DAE2P to a
Storage Processing Device
If you are connecting the first DAE2P in a loop to a storage processing device,
such as an SPE or DPE2:
1. Plug an HSSDC2-HSSDC copper cable into the primary (PRI)
connector on each link control card (LCC) in the DAE2P.
CAUTION
!
Orient the HSSDC2 connectors as shown below. An audible/tangible
click indicates that the cable is completely seated in the LCC connector.
2. Plug the larger HSSDC end of the cable into the appropriate back-end
(BE) connector on the storage processor device. For more
information, refer to the setup guide or the hardware reference for
the device.
YOUR NEXT STEP
Once your DAE2P is up and running, you can integrate it into your existing
storage system, or initialize a new system. Refer to the EMC Navisphere
Manager Administrator’s Guide (P/N 069001125) or the appropriate checklist in
the EMC Installation Roadmap for CX-Series, AX-Series, and FC-Series Storage
Systems (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 DAE2P.
