Communications Statements
The following statement applies to this product. The statement for other products intended
for use with this product appears in their accompanying manuals.
Federal Communications Commission (FCC) Statement
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his
own expense.
Properly shielded and grounded cables and connectors must be used in order to meet FCC
emission limits. Neither the provider nor the manufacturer are responsible for any radio or
television interference caused by using other than recommended cables and connectors or
by unauthorized changes or modifications to this equipment. Unauthorized changes or
modifications could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
United Kingdom Telecommunications Safety Requirements
This equipment is manufactured to the International Safety Standard EN60950 and as such
is approved in the UK under the General Approval Number NS/G/1234/J/100003 for indirect
connection to the public telecommunication network.
The network adapter interfaces housed within this equipment are approved separately, each
one having its own independent approval number. These interface adapters, supplied by the
manufacturer, do not use or contain excessive voltages. An excessive voltage is one which
exceeds 70.7 V peak ac or 120 V dc. They interface with this equipment using Safe Extra
Low Voltages only. In order to maintain the separate (independent) approval of the
manufacturer’s adapters, it is essential that other optional cards, not supplied by the
manufacturer, do not use main voltages or any other excessive voltages. Seek advice from a
competent engineer before installing other adapters not supplied by the manufacturer.
European Union (EU) Statement
This product is in conformity with the protection requirements of EU Council Directive
89/336/EEC on the approximation of the laws of the Member States relating to
electromagnetic compatibility.
Neither the provider nor the manufacturer can accept responsibility for any failure to satisfy
the protection requirements resulting from a non-recommended modification of the product,
including the fitting of option cards not supplied by the manufacturer.
This product has been tested and found to comply with the limits for Class A Information
Technology Equipment according to CISPR 22 / European Standard EN 55022. The limits

xOperator Guide
for Class A equipment were derived for commercial and industrial environments to provide
reasonable protection against interference with licensed communication equipment.
Attention: This is a Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate measures.
International Electrotechnical Commission (IEC) Statement
This product has been designed and built to comply with IEC Standard 950.
Avis de conformité aux normes du ministère des Communications du
Canada Cet appareil numérique de la classe A respecte toutes les exigences du Réglement sur le

Laser Safety Information
The optical drive in this system unit is a laser product. The optical drive has a label that
identifies its classification. The label, located on the drive, is shown below.
CLASS 1 LASER PRODUCT
LASER KLASSE 1
LUOKAN 1 LASERLAITE
APPAREIL A LASER DE CLASSE 1
TO IEC 825:1984 CENELEC EN 60 825:1991
The optical drive in this system unit is certified in the U.S. to conform to the requirements of
the Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21
CFR) Subchapter J for Class 1 laser products. Elsewhere, the drive is certified to conform to
the requirements of the International Electrotechnical Commission (IEC) 825 (1st edition
1984) and CENELEC EN 60 825:1991 for Class 1 laser products.
CAUTION:
A class 3 laser is contained in the device. Do not attempt to operate the drive while it
is disassembled. Do not attempt to open the covers of the drive as it is not
serviceable and is to be replaced as a unit.
Class 1 laser products are not considered to be hazardous. The optical drive contains
internally a Class 3B gallium-arsenide laser that is nominally 30 milliwatts at 830
nanometers. The design incorporates a combination of enclosures, electronics, and
redundant interlocks such that there is no exposure to laser radiation above a Class 1 level
during normal operation, user maintenance, or servicing conditions.

Chapter 1. CPU Enclosure Description
This chapter contains information about system unit features, parts, and devices on the
7015 Model R30, R40, or R50 CPU Enclosures.
CPU Enclosure
The 7015 CPU Enclosures are rack-mounted CPUs containing a CPU module, I/O module,
media module, and a power supply with a possible optional second power supply.
The CPU module is located in the front half of the CPU enclosure and contains CPU cards,
memory cards, and an I/O card.
The media module is located above the CPU module at the front of the CPU enclosure and
contains a disk drive, CD-ROM drive, an optional media position for either a 5.0GB 8 mm
tape drive, 4GB 4 mm tape drive, 1/4-inch tape drive, or another CD-ROM drive, and an
operator panel assembly containing a 3.5-inch diskette drive. The R50 Media Module has a
position for an optional second disk drive.
The I/O module is located in the rear half of the CPU enclosure and contains two I/O planars
containing a total of 16 Micro Channel adapter slots. The power supply and optional second
power supply position are located above the adapter positions.
A system interface board (SIB) is located next to the I/O module and contains an RS485 port
(in) an RS485 port (out), a Battery Backup Unit (BBU) connector, parallel port, serial port 1,
serial port 2, and serial port 3.
The CPU Enclosure can be installed in a 7015 Model R00 rack with other optional
compatible drawers and devices such as disk drive drawers and SCSI media drawers. The
power distribution system in a 7015 Model R00 rack can contain either a power distribution
bus, power distribution unit, or a battery backup unit. For information about options and
compatible optional drawers that can be used with the 7015 Model R30 CPU Enclosure in a
7015 Model R00 rack, see the Adapters, Devices, and Cable Information manual, form
number SA23-2764.
