REV 01
July 2017
This document describes how to add an optional 80-drive DAE in
Unity All Flash and Unity Hybrid systems.
You will install the 80-drive DAE from the front of the rack, after installing the snap-in
rails into the selected space in the rack.
CAUTION
The enclosure is heavy and should be installed into or removed from 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.
Note
You do not have to power off any components to add a 80-drive DAE. If an additional
12-Gb SAS back-end I/O module is required to complete the installation, persisting that
I/O module requires a coordinated reboot of the array.
NOTICE
When Data at Rest Encryption is enabled, only drives that meet at least one of these
requirements can be used: factory new drives, securely erased/sanitized drives, or
previously encrypted drives.

Handling replaceable units
This section describes the precautions that you must take and the general procedures
that you must follow when removing, installing, and storing any replaceable unit.
Avoiding electrostatic discharge (ESD) damage
When replacing or installing hardware units, 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. Follow the procedures below to prevent damage to the
equipment.
Be aware of the following requirements:
lProvide enough room to work on the equipment.
lClear 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.
lDo not remove replacement or upgrade units from their antistatic packaging until
you are ready to install them.
lBefore you begin service, gather together the ESD kit and all other materials you
will need.
lOnce servicing begins, avoid moving away from the work site; otherwise, you may
build up an electrostatic charge.
lUse ESD anti-static gloves or an ESD wristband (with strap).
If using an ESD wristband with a strap:
nAttach the clip of the ESD wristband to the ESD bracket or bare metal on a
cabinet/rack or enclosure.
nWrap the ESD wristband around your wrist with the metal button against your
skin.
nIf a tester is available, test the wristband.
lIf an emergency arises and the ESD kit is not available, follow the procedures in
Emergency Procedures (without an ESD kit).
Emergency procedures (without an ESD kit)
In an emergency when an ESD kit is not available, use the following precautions to
reduce the possibility of an electrostatic discharge by ensuring that your body and the
subassembly are at the same electrostatic potential.
NOTICE
These precautions are not a substitute for the use of an ESD kit. Follow them only in
the event of an emergency.
lBefore touching any unit, touch a bare (unpainted) metal surface of the cabinet/
rack or enclosure.
Adding an optional 80-drive DAE
Handling replaceable units 3

lBefore removing any unit from its antistatic bag, place one hand firmly on a bare
metal surface of the cabinet/rack or enclosure, and at the same time, pick up the
unit while it is still sealed in the antistatic bag. Once you have done this, do not
move around the room or touch other furnishings, personnel, or surfaces until you
have installed the unit.
lWhen you remove a unit from the antistatic bag, avoid touching any electronic
components and circuits on it.
lIf you must move around the room or touch other surfaces before installing a unit,
first place the unit back in the antistatic bag. When you are ready again to install
the unit, repeat these procedures.
Hardware acclimation times
Systems and components must acclimate to the operating environment before
applying power. This requires the unpackaged system or component to reside in the
operating environment for up to 16 hours in order to thermally stabilize and prevent
condensation.
Refer to the table, Table 1 on page 4, to determine the precise amount of
stabilization time required.

NOTICE
lIf there are signs of condensation after the recommended acclimation time has
passed, allow an additional eight (8) hours to stabilize.
lSystems and components must not experience changes in temperature and
humidity that are likely to cause condensation to form on or in that system or
component. Do not exceed the shipping and storage temperature gradient of
45°F/hr (25°C/hr).
lDo NOT apply power to the system for at least the number of hours specified in
the table, Table 1 on page 4. If the last 24 hours of the transit/storage
environment is unknown, then you must allow the system or component 16 hours
to stabilize in the new environment.
Removing, installing, or storing replaceable units
Use the following precautions when removing, handling, or storing replaceable units:
CAUTION
Some replaceable units have the majority of their weight in the rear of the
component. Ensure that the back end of the replaceable unit is supported while
installing or removing it. Dropping a replaceable unit could result in personal
injury or damage to the equipment.
NOTICE
lFor a module that must be installed into a slot in an enclosure, examine the rear
connectors on the module for any damage before attempting its installation.
lA sudden jar, drop, or even a moderate vibration can permanently damage some
sensitive replaceable units.
lDo not remove a faulted replaceable unit until you have the replacement available.
lWhen handling replaceable units, avoid electrostatic discharge (ESD) by wearing
ESD anti-static gloves or an ESD wristband with a strap. For additional
information, refer to Avoiding electrostatic discharge (ESD) damage on page 3.
lAvoid touching any exposed electronic components and circuits on the replaceable
unit.
lNever use excessive force to remove or install a replaceable unit. Take time to
read the instructions carefully.
lStore a replaceable unit in the antistatic bag and the specially designed shipping
container in which you received it. Use the antistatic bag and special shipping
container when you need to return the replaceable unit.
lReplaceable units must acclimate to the operating environment before applying
power. This requires the unpackaged component to reside in the operating
environment for up to 16 hours in order to thermally stabilize and prevent
condensation. Refer to Hardware acclimation times on page 4 to ensure the
replaceable unit has thermally stabilized to the operating environment.

Handling replaceable units 5

NOTICE
Your storage system is designed to be powered on continuously. Most components
are hot swappable; that is, you can replace or install these components while the
storage system is running. However, the system requires that:
lFront bezels should always be attached to ensure EMI compliance. Make sure you
reattach the bezel after replacing a component.
lEach slot should contain a component or filler panel to ensure proper air flow
throughout the system.
Unpacking a part
Procedure
1. Wear ESD gloves or attach an ESD wristband to your wrist and the enclosure in
which you are installing the part.
2. Unpack the part and place it on a static-free surface.
3. If the part is a replacement for a faulted part, save the packing material to
return the faulted part.
Standard touch point colors
Touch points are component locations where you can:
lGrip the hardware to remove or install a component.
lOpen or close a latch.
lTurn a knob to open, close, or adjust a component.
Standard touch point colors are terra-cotta (orange) or blue.
Note
Within this documentation, the color orange is used instead of terra-cotta for
simplicity.
Table 2 Standard touch point colors
Touch point color Description
Terra-cotta
(orange)
This color indicates that you can perform the task, such as remove a
component with a terra-cotta (orange) lever, while the system remains
powered (up/on).
Note
Some tasks may require additional steps.
Blue This color indicates that a shutdown of the system or component is
required before you can perform the task, such as removing a
component with a blue lever.

Handling disks
Disks are extremely sensitive electronic components. Always handle a disk gently, and
observe the following guidelines:
lFollow the instructions described in Removing, installing, or storing replaceable
units on page 5.
lDo not stack disks upon one another, or place them on hard surfaces.
lMake sure that the replacement disk has the same part number or the part number
of an approved replacement for the faulted disk. The part number (PN005xxxxxx)
appears on the disk. A replacement disk should be the same type (example: SAS,
FLASH) and have the same capacity (size and speed) as the disk it is replacing.
lWhen removing a spinning disk, pull the disk partially out of the slot, then wait 30
seconds for the drive to spin down before removing it.
lWhen installing multiple disks in a powered up system, wait at least 10 seconds
before sliding the next disk into position.
lPlace disks on a soft, antistatic surface, such as an industry-standard antistatic
foam pad or the container used to ship the disk.
Adding an optional 80-drive DAE
Handling disks 7

Adding the new 80-drive DAE
Take the following actions to install the new 80-drive DAE into the system.
Choosing where to install the DAE
Before installing the new DAE, you should determine the placement of the new
enclosure within the rack.
Choose a 3U space in the rack for the new DAE after reviewing the following
guidelines:
lLeave 1U of space at the bottom of the rack for access to cables.
lPopulate all 80-drive DAEs starting from the bottom of the rack before adding
DPEs and other DAEs.
CAUTION
Improper positioning of the 80-drive DAE may cause the cabinet to become
top-heavy and susceptible to falling.
lIf there is already an 80-drive DAE in the rack, place the new DAE directly above
the existing DAE.
lWhen adding a 80-drive DAE to an existing installation, ensure that a 25-slot DAE,
15-slot DAE, or the DPE itself, is not positioned between two 80-drive DAEs. If the
DAE is improperly positioned, it causes a serviceability tunnel and makes servicing
the DPE or DAEs difficult.
Special considerations for adding an 80-drive DAE
The 80-drive DAE supports back-end x8 cabling. However, special steps must be
taken before powering on the system.
If you are connecting the DAE to a 4-port SAS SLIC that requires x8 connectivity,
insert the SAS cable into the 4-port SAS SLIC before persisting the SLIC. The 4-port
SAS SLIC must be persisted with the cable inserted for x8 connectivity.
Note
If the SAS back-end SLIC is powered on without any cables inserted, it is
automatically set at x4 and cannot be used for x8 lane cabling.
80-drive DAE and SLIC port mapping information
BE 0 and 1 can only be x4 and thus will always be back end (BE) 0 and 1.
15-drive, 25-drive and 80-drive DAEs are all valid configurations when connected to
BE 0 and/or 1 as x4.
SLIC BE ports 2 through 5 can be either x4 or x8. They will persist at the time of the
install. To persist x8, at the very least the x8 cable must be in place. The x4 cable does
not have to be in place to be x4.
15-drive, 25-drive and 80-drive DAEs are all valid configurations when connected to
BE 2 through 5 as x4. If they are x4 they will map to BE 2, 3, 4 and 5. If they are x8
they will map to 2 and 4. Only 80-drive DAEs can be connected x8 to BE 2 or 4
therefore an x8 80-drive DAE will always be on either BE 2 or 4.
Field Upgrade Procedure
8Unity All Flash and Unity Hybrid Field Upgrade Procedure

Splitting ports on the SAS SLIC
It is possible to have an x4 on BE 2 and BE 3 with and x8 on BE 4 (ports 2 and 3). It is
also possible to have an x8 on BE 2 (ports 0 and 1) with and x4 on BE 4 and BE 5
(ports 2 and 3).
The mapping of the BE busses is a physical mapping. A DAE’s presence has no effect.
lPhysical ports 0 and 1 of the SLIC will always be bus 2 when configured as x8.
lPhysical ports 0 and 1 of the SLIC will always be bus 2 and bus 3 when configured
as x4.
lPhysical ports 2 and 3 of the SLIC will always be bus 4 when configured as x8.
lPhysical ports 2 and 3 of the SLIC will always be bus 4 and bus 5 when configured
as x4.

Working with the portable lift
If the DAE with all of the FRUs removed is being installed, the chassis can be installed
without using the lift. If the DAE is populated with FRUs prior to installing, then this
task requires the use of a portable lift.
The portable lift commonly used by service personnel is manufactured by Alum-A-Lift.
Instructions for this lift are included in the lift kit. Refer to "http://
www.corkc4.isus.emc.com/wiki/index.php/Lift_Tool". which describes the Lift

equipment, the ordering process, and Links to training material. The Lift Tool Training
Video and Demo on Lift tool using the Voyager assembly (Voyager is the name given
to a Disk enclosure used in several products), are also linked on this page.
Note
If you are using a portable lift other than the Alum-A-Lift, adapt these instructions as
necessary while following all required safety requirements.
CAUTION
The portable lift commonly used by service personnel has two configurations -
one with the lower mast only and one with both the lower and upper masts. The
lower mast configuration is rated for 400 pounds and is for raising or lowering
objects 28U (49 inches) or less above the floor. The dual mast configuration is
rated well under 200 pounds and is for raising objects more than 28U (49 inches)
above the floor.
lFor installations at or below 49 inches, you must use the lower mast
configuration.
lFor installations above 49 inches, use the "Voyager" conversion kit, rated for
225 pounds, and a support table with the lower mast configuration.
Planning your lift
You can use the lift positioned along the side of the DAE or directly in the front of it.
If possible, position the lift adjacent to the LONG side of the enclosure. This reduces
the front clearance required to 50". Aligning the portable lift perpendicular to the
chassis also reduces the possibility of the chassis sliding off the lift and negates the
requirement to adjust the arm width to approximately 17".
