Physical
specifications
Transportation and
delivery guidelines
Chapter 3, “Physical and Environmental Specifications,” provides
overall system dimensions for the DLm systems.
Mode of transport guidelines:
◆For a DLm system delivered within the United States or Canada,
EMC recommends an air-ride truck. The DLm system is wrapped
in custom-designed shipping material, crated, and palletized.
◆For a DLm system delivered internationally, EMC recommends
shipment by air freight. Unless otherwise instructed, the EMC
Traffic Department arranges for delivery directly to the
customer’s computer room.
To ensure successful delivery of DLm systems, EMC has formed
partnerships with specially selected moving companies. These
companies have moving professionals trained in the proper handling
of large, sensitive systems. These companies provide the appropriate
personnel, floor layouts, and any ancillary moving equipment
required to facilitate delivery.

requirements
Layout and space
recommendations
Remote support
DLm requires the environmental specifications outlined in
“Environmental data” on page 39. Ensure that the site meets or
exceeds the specifications listed for both nonraised floor and raised
floor environments.
The Presite Survey, completed with the EMC Systems Engineer,
reports the Fibre connection (FICON) or Enterprise Systems
Connection (ESCON) cable lengths required for each host connection
to the DLm. From a physical planning perspective, review the routing
paths from the hosts to the DLm system. Resolve any physical access
issues prior to installation day.
Layout and space considerations are described in “Placement
options” on page 44.
When moving the DLm bays down an incline, the rear of the bay
must go first and when moving up an incline, the rear of the bay
must go last.
Remote support is an important and integral part of the EMC
customer service and support strategy. Communication between the
EMC Customer Support Center and the DLm occurs either through
IP connections to the customer's local area network, or through the
external serial modem connected to the DLm, which requires
customers to provide one dedicated phone line for the modem.

Power Requirements
Single-phase power extension cords and connectors
Each DLm bay has four single-phase power distribution panel (PDP)
assemblies and four power distribution units (PDU).
DLm960 NAS bay and NAS expansion bay require four power drops.
The DLm4080 expansion storage bay and DLm4080 storage bay with
more than nine DAEs. DLm4080 storage bay with upto nine DAEs
requires two power drops.
These bays require two power drops each:
◆The DLm120 bay
◆The DLm960 VTEC bay
◆The DLm960 Storage bays
◆The DLm4020 bay
◆The DLm4080 storage bay with up to nine DAEs
For these bays, the upper PDUs are cabled to the lower PDPs in
manufacturing.
These bays require four power drops:
54
◆The DLm960 NAS bay
◆The DLm960 NAS expansion bay
◆The DLm4080 system bay
◆The DLm4080 expansion storage bay
◆The DLm4080 storage bay with more than nine DAEs
Regardless of the number of power drops required, each DLm bay

DLm touch current compliance
CAUTION
!
DLm is designated as a fixed (stationary) electrical equipment with
high earth-leakage markings. Connect the cabinets to the customer
AC supply with the recommended rated current breakers and the
attached cables. “DLm power requirements” on page 50 provides
details of recommended circuit breaker ratings. These recommended
breaker ratings are based on the maximum kW loading of the cabinet
and not on the KVA figures of a particular configuration. The KVA
values listed in this manual are intended for air conditioning and
utility loading purposes only. “Power and cooling data” on page 41
contains more information.
Do not connect the DLm VTEC bay power supplies on separate
Main and Auxiliary circuit panels to differential trip devices. These
devices are typically called Ground Fault Circuit Interrupter
(GFCI), Ground Fault Interrupter (GFI), Earth Leakage Circuit
Breaker (ELCB), or Residual Current Circuit Breakers.
Power Requirements
Because DLm systems are high earth-leakage devices, differential trip
devices (typically 30 mA) are not recommended due to random
activation during utility feed distortions and power line transients
interacting with the cabinet noise filters. These differential devices
have trip ratings of 5 mA to 500 mA and are mostly intended for
consumer goods rather than fixed devices.
If the DLm cabinet is correctly grounded to the customer’s AC power
source, leakage current will not produce a voltage leading to
electrical shock. Serious insulation breakdowns will trip the breakers
feeding the cabinet or, preferably first clear fuses in individual
internal modules closest to the fault.
DLm touch current compliance
59
Page 60
Power Requirements
Regulatory compliance
DLm meets regulatory requirements as referenced by the following
UL/IEC/EN 60950 3rd Edition:
5.1.7 Equipment with touch (leakage) current exceeding 3.5mA.
For Stationary Permanently Connected Equipment, or Stationary
Pluggable Equipment Type B, having a main protective earthing
terminal, if the Touch (Leakage) Current measurements exceed 3.5mA
r.m.s., following conditions apply:
• The r.m.s. Protective Conductor Current will not exceed five percent
of the input current per line under normal operating conditions. If
the load is unbalanced, the largest of the single-phase currents shall
be used for this calculation.
To measure the Protective Conductor Current, the procedure for
measuring Touch Current is used, but the measuring instrument is
replaced by an ammeter of negligible impedance.
• The cross-sectional area of the Protective Bonding Conductor will
not be less than 1.0 mm squared in the path of high Protective
Conductor Current.
• A label with similar wording shall be affixed adjacent to the
equipment AC MAINS SUPPLY connection:
HIGH LEAKAGE CURRENT
Earth connection essential
before connecting supply.
60
The DLm configurations are Stationary Pluggable Type B systems,
and have been extensively tested and certified to meet the above
standard, including the application of the warning label, EMC P/N
046-000-309, in English and French. The label location for the DLm
configuration is on the inside of the front door.
EMC Disk Library for mainframe Physical Planning Guide
Page 61
Choosing a UPS
Power Requirements
The VTEC and Storage Controllers (Data Movers) are stateless, so no
battery backup is required. In the event of a power failure, the
Storage Processor writes contents of the write cache to disk, before
shut down. Although DLm does not require a battery backup to
ensure data integrity, to avoid potential downtime, purchase a UPS
from a qualified vendor.
EMC neither offers nor recommends any specific UPS suppliers or
product type to its customers. However EMC uses preferred
suppliers for UPS systems in their facilities. Therefore, if you, the
customer, are implementing a UPS, EMC recommends the following:
◆When you are planning the UPS solution for a DLm and the host
system is presently (or will potentially be) protected with a UPS,
the battery backup time you propose for the DLm UPS solution
should match that of the host system.
◆The DLm requires independent zone B and zone A power feeds
for each bay.
◆The UPS should be equipped with an internal output isolation
transformer.
◆The UPS should be installed as a separately derived AC source
using neutral and ground wiring to preserve the fault tolerance
specification of the DLm power system.
◆Depending on the power requirements for your DLm system
operation, an isolation transformer/stabilizer installed in front of
the UPS could further buffer the AC utility environmental factors
from reaching DLm. To determine if an isolation
transformer/stabilizer is needed, consult a licensed electrician.
