IMPORTANT
Due to the extensive variety of disk module types, Table 28 only lists two disk types. EMC
recommends that you refer to the latest
EMC VNX5500, VNX5700, and VNX7500 Series
Storage Systems Disk and OE Matrix
Guide to ensure that you have the correct part for
your configuration.
4U, 60 (2.5- or 3.5-inch) DAE
IMPORTANT
The 4U, 60 (2.5- or 3.5-inch) DAE is assembled and configured at the factory before
shipping. If replacing or adding a 4U, 60 (2.5- or 3.5-inch) DAE becomes necessary. Refer
to the CAUTION on page 45 that discusses the mounting and servicing of the 4U, 60, (2.5-
or 3.5-inch) DAE in a 40U Dense rack. Additionally, refer to the
Replacing or Adding a DAE
for the 4U, 60, (2.5- or 3.5-inch) DAE documents.

Access to internal components in a 4U, 60 DAE mounted 31U (4.5 feet or 1.38 meters) or
more above the floor requires special equipment and is restricted to authorized service
personnel only. Attempts to service disks, fans, or LCCs mounted 31U or higher without
appropriate tools and personnel might result in serious personal injury.
The 4U, 60 (2.5- or 3.5-inch) DAE includes up to 60, 2.5- or 3.5-inch disk drives.
Supporting 6-Gb/s data transfer speeds, this DAE has the following hardware
components: three fan (or cooling modules), 60 disks (30 per side), two Link Control
Cards (LCCs), two Inter Connect Modules (ICMs), and two power supplies.
To replace or add any of these components, refer to their respective Customer
Replaceable Unit (CRU) procedure for the 4U, 60 DAE. For example, to replace a disk drive,
refer to the
Replacing a disk in a 60-disk enclosure document .
IMPORTANT
To accommodate the 4U, 60 DAE, a 40U Dense rack is required. The Dense rack is 44
inches (111.76 cm) deep. Because each DAE weighs 57.8 lb (26.28 kg) empty and 213 lb
(96.62 kg) fully loaded, a DAE interlock mechanism is provided in the Dense rack to
prevent the extension of no more than one DAE at a time.
