Laser Safety Information
Notes:
1. The information given here applies only to 7133s that have the Advanced SSA
Optical Extender (Pair) feature.
2. The Advanced SSA Optical Extender, referred to in this information as an optical
extender, is part of the serial optic channel converter assembly.
This system contains a laser product called the optical extender. In the United States,
the optical extender is certified as a Class 1 laser product that conforms to the
requirements contained in the Department of Health and Human Services (DHHS)
regulation 21 CFR Subchapter J. Internationally, the optical extender is certified as a
Class 1 laser product that conforms to the requirements contained in the International
Electrotechnical Commission (IEC) standard 825-1 (1993).
Class 1 laser products are not considered to be hazardous. The optical extender
internally contains an indium gallium arsenide / indium phosphide (InGaAs/InP)
semiconductor laser diode emitting in the wavelength range of 1280 to 1340
nanometers. This laser diode is a Class 1 laser that is rated at 5.0 milliwatts. The
design of the optical extender is such that access to laser radiation above a Class 1
level during operation, user maintenance, or service conditions is prevented.

Chapter 1. Reference Information
Are You Using the Correct Book? Do not use this book if you are servicing a 7133
Model 010, 020, 500, or 600 SSA Disk Subsystem. For the correct book, see Related
Publications in the “Additional Information”appendix (in this book) for your using
system.
The 7133 Models D40 and T40 Serial Disk Systems (see Figure 1) are Serial Storage
Architecture (SSA) disk subsystems that can be attached to any computer that provides
support for SSA. Model D40 1 is a rack-mounted unit that can be installed in a
standard Electrical Industries Association (EIA) 19-inch rack. Model T40 2 is a
deskside unit.
The 7133 can contain up to 16 SSA disk drive modules (eight at the front and eight at
the back). The disk drive modules are connected to each other in strings of four
modules (two strings at the front of the 7133, and two strings at the back). These
strings can be connected to each other, to strings in other 7133s, or to SSA
attachments (for example, SSA adapters). The SSA attachments can be in separate
using systems or in the same using system.

The 7133 can be disconnected from its related SSA attachments while the using system
is running. Also, most of the field-replaceable units (FRUs) of the 7133 can be removed
and replaced while the 7133 and the using system are running. For a list of those
FRUs, see “Concurrent Maintenance”on page 137.
Each 7133 Model D40 or Model T40 contains two power supply assemblies and three
fan assemblies, which together provide all the necessary power and cooling. It also
contains a controller card, which monitors and controls the various functions of the
7133. For further details about the controller card, see “Controller Card”on page 3.
The 7133 Models D40 and T40 can be configured to the using system as devices if
applicable. See “Configuring a 7133 to the Using System”in the “Additional Information”
appendix (in this book) for your using system. When a 7133 is configured as a device:
vErrors that are detected in the 7133 are logged in the system error log against that
7133.
vVital product data (VPD) for the 7133 can be accessed.
Each FRU contains its own VPD. A using system can access this VPD while the 7133
is being configured to that particular using system.
Enclosure configuration information is stored in several locations in the 7133 to allow
concurrent replacement of FRUs. (Such information might be, for example, the
information that is displayed on the ID display of the 7133.) When a new FRU is
installed, any special configuration information that is required by that FRU is read from
other locations in the 7133. That information is then used to update the new FRU. To
ensure that the configuration is not corrupted or changed, always exchange FRUs one
at a time. Do not exchange multiple FRUs between 7133s.
