The 4U, 60 (2.5- or 3.5-inch) disk drive DAE (DAE7S) 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
the 4U, 60, (2.5- or 3.5-inch) DAE in a 40U Dense rack. Additionally, refer to the
or Adding a DAE documents for the 4U, 60, (2.5- or 3.5-inch) DAE.
Access to internal components in a 4U, 60 DAE that are 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 that are
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 (DAE7S) 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.
IMPORTANT
When the 4U, 60 DAE is used in combination with the 3U, 15 DAE, the 4U or the 3U DAE
can accommodate the Vault drives. The use of which DAE will use the Vault drives will be
determined by the customer requirements as all 40U Dense racks with the 4U DAE are
customer requested and assembled and configured at the factory.
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,
