angeschlossen wird.
Additional warnings
and cautions
Before attempting to service the EMC hardware described in this
document, observe the following additional Warnings and Cautions:
WARNING
The hardware enclosure contains no user-serviceable parts, so it
should not be moved or opened for any reason by untrained persons.
If the hardware needs to be relocated or repaired, only qualified
personnel familiar with safety procedures for electrical equipment
and EMC hardware should access components inside the unit or
move the unit.
WARNING
This product operates at high voltages. To protect against physical
harm, power off the system whenever possible while servicing.
WARNING
In case of fire or other emergency involving the EMC product, isolate
the product’s power and alert appropriate personnel.
CAUTION
!
Trained personnel are advised to exercise great care at all times
when working on EMC hardware.
Remember to:

Warnings and Cautions
Static precautions EMC incorporates state-of-the-art technology in its designs, including
the use of LSI and VLSI components. These chips are very susceptible
to damage caused by static discharge and need to be handled
accordingly.
CAUTION
!
Before handling printed circuit boards or other parts containing
LSI and/or VLSI components, observe the following precautions:
◆Store all printed circuit boards in antistatic bags.
◆Use a ground strap whenever you handle a printed circuit board.
◆Unless specifically designed for non disruptive replacement, never
plug or unplug printed circuit boards with the power on. Severe
component damage may result.

Planning overview
This section provides an overview of the planning requirements for
EMC® Disk Library for mainframe (DLm) installation. It reviews
EMC’s responsibilities and outlines customer’s responsibilities.
Note: Inform EMC of any labor union-based restrictions or security clearance
requirements prior to delivery.
The DLm systems must be installed in a properly equipped computer
room, with controlled temperature and humidity, proper airflow and
ventilation, proper power and grounding, system cable routing
facilities, fire equipment, and so on. Although a raised floor is not
required, it is recommended. One or more planning sessions with
your EMC Systems Engineer and EMC Customer Support
Representative will be necessary to close all the details related to
installation. Table 1 on page 18 lists the responsibility summary at the
first planning session.
Table 1 Pre-installation responsibility summary
EMC Customer
Provide all details necessary for site planning and preparation. Provide an environment that supports safe installation of the
DLm system and promotes its reliable long-term operation.
Complete and process the Installation Planning Task Sheet and
Presite Survey.
Provide appropriate modem phone line, power, cooling and
ventilation, humidity control, floor load capability, and service
clearances as required.
Arrange for shipment and delivery through an appropriate
method.
Participate in planning sessions as required to ensure a smooth
and uncomplicated installation.
Install a properly working system.

General
considerations
Before installing the DLm system at your site, consider these factors:
◆Weight capacities of the service elevator if delivery is to another
floor
◆Availability of an equipment ramp if the receiving floor is not on
level with computer room floor
Note: All portions of the bay should clear ramp and threshold slopes up
to 1:10 (rise to run ratio), per Code of Federal Regulations – ADA
Standards for Accessible Design, 28 CFR Part 36.
◆Weight capacities of the loading dock
◆Weight capacities of the tailgate
Other requirements Other requirements are:
◆Appropriate floor covering required for protection
◆Direct dial-up phone line (for remote support) within six feet (two
meters) of the unit
◆Hardware power requirements
“Environmental data” on page 39 specifies the power requirements
for DLm bays.
