Appendix C. Specifications for non-IBM rack installation
The following instructions provide safety requirements and rack specifications for
installing DS5000 storage subsystems and DS5000 storage expansion enclosures
into non-IBM racks.
Note: The information in this section applies to 19–inch racks. It is your
responsibility, working with your rack manufacturer,to ensure that the
non-IBM rack chosen meets the safety requirements and specifications listed
in this section.

General safety requirements for IBM products installed in a non-IBM

rack or cabinet

The general safety requirements for IBM products installed in non-IBM racks are:
1. Any product or component that plugs into either an IBM power distribution unit
or mains power (via a power cord), or uses any voltage over 42 V ac or 60 V
dc (considered to be hazardous voltage) must be Safety Certified by a
Nationally Recognized TestLaboratory (NRTL) for the country in which it will
be installed.
Some of the items that require safety certification may include: the rack or
cabinet (if it contains electrical components integral to the rack or cabinet), fan
trays, power distribution unit, uninterruptible power supplies, multi-outlet strips,
or any other products installed in the rack or cabinet that connect to hazardous
voltage.
Examples of OSHA-approved NRTLs for the U.S.:
vUL
vETL
vCSA (with CSA NRTL or CSA US mark)
Examples of approved NRTLs for Canada:
a. UL (Ulc mark)
b. ETL (ETLc mark)
c. CSA
The European Union requires a CE mark and a Manufacturer’s Declaration of
Conformity (DOC).
Certified products should have the NRTL logos or marks somewhere on the
product or product label. However, proof of certification must be made
available to IBM upon request. Proof consists of such items as copies of the
NRTL license or certificate, a CB Certificate, a Letter ofAuthorization to apply
the NRTL mark, the first few pages of the NRTLcertification report, Listing in
an NRTL publication, or a copy of the ULYellow Card. Proof should contain
the manufacturer's name, product type and model, standard to which it was
certified, the NRTL name or logo, the NRTLfile number or license number, and
a list of any Conditions of Acceptance or Deviations.A Manufacturer’s
Declaration is not proof of certification by an NRTL.
2. The rack or cabinet must meet all electrical and mechanical safety legal
requirements for the country in which it is installed.
The rack or cabinet must be free of exposed hazards (such as voltages over
60 V dc or 42 V ac, energy over 240 VA, sharp edges, mechanical pinch
points, or hot surfaces).
