Safety and Environmental Notices ix
Laser Safety Information
Laser Safety Information (for IBM Fiber Optic Link Products)
CAUTION:
This system may contain laser products called the IBM Optical Link Module
(OLM), Serial Optical Converter (SOC), or Optical Link Card (OLC). In the
United States, these fiber optic links are certified by IBM as Class I laser
products that conform to the requirements contained in the Department of
Health and Human Services (DHHS) regulation 21 CFR Subchapter J.
Internationally, these fiber optic links are certified as Class 1 laser products that
conform to the requirements contained in the International Electrotechnical
Commission (IEC) standard 825-1 (1993), the CENELEC (European Committee for
Electrotechnical Standardization) European Norm standard EN60825-1 (1994), and
the Verband Deutscher Elektrotechniker (VDE) standard 0837 (1986). The
German testing institute, VDE, has assigned certificate registration number 3642
to all IBM OLM, SOC, and OLC laser products.
The fiber optic links incorporate laser diodes that are either of the gallium
aluminum arsenide (GaAlAs) type that emits in the wavelength range of 770 to
860 nanometers or of the indium gallium arsenide phosphide (InGaAsP) type
that emits in the wavelength range of 1270 to 1355 nanometers. These fiber optic
links incorporate discrete laser diodes that are Class 3B laser products with a
rating of approximately 5.0 milliwatts peak power. Once the lasers are
assembled into the OLM, SOC, or OLC, the automatic laser control safety system
prevents laser emissions from exceeding Class 1 limits during both operation
and service. There are no user maintenance operations or adjustments to be
performed on IBM OLM, SOC, or OLC products. Class 1 laser products are not
considered to be hazardous under any conditions.
The fiber optic links are designed and certified for use in applications with
point-to-point optical links only. Use of these products with multiple input or
multiple output links (for example, star coupler or fiber splitter) is not
compatible with the OLM, SOC, or OLC design and function. In addition, the
fiber optic link products must be connected only to other IBM OLM, SOC, or
OLC (of the same model) or a compatible laser product. This is especially true
for those models that contain both the open link detection safety system called
Open Fiber Control (OFC) and the laser power control safety system. (All OLM,
SOC, and OLC models contain the laser power control safety system. All OLC
models contain OFC, all SOC model have No-OFC, but some OLM models are
available with OFC and some have No-OFC.)
These requirements are necessary for the correct operation of the IBM OLM,
SOC, and OLC products in any optical communication system. Failure to follow
these restrictions could result in the system not operating correctly and the
creation of points of access that emit laser radiation above the Class 1 limit
specified by either the IEC 825-1 (1993) standard internationally or the DHHS
regulation 21 CFR Sub J in the United States. (RSFTC211)

DST operates in stand-alone, limited, and full paging environments. The DST tools
and functions vary depending on the paging environment and the release level of
the operating system. For more information, see “System paging environments” on
page 2.
System Service Tools (SST) provides a way to access a subset of the service tools
that DST offers without requiring access to DST. SST is available when OS/400 is
operational, and can be accessed using the STRSST CL command.
Dedicated Service Tools requirements
Attention: It is a requirement to change the password the first time anyone signs
on to DST or SST. The customer engineer needs to give the new (changed)
password to the customer or have the customer change the password.
To use DST, you must have the following items:
v The disk that contains the Licensed Internal Code (the load-source disk).
Note: When you perform an alternate initial program load (IPL) to DST, you do
not need the load-source disk.
v An operational workstation on bus 1 as either a primary console or an
operations console.
© Copyright IBM Corp. 1997, 2002 1
v One workstation for each system partition.
v A valid service tools user ID and password to sign on to DST. IBM supplies
service tools user IDs that have different levels of privileges. See “Work with
service tools user IDs” on page 25 for more information.
To make a printout, attach the printer to the workstation I/O processor or storage
media unit that is performing the service function. The printer that is used with
DST for service tool output must be an SCS-type data stream printer (for example,
type 5224).
System paging environments
The amount of assistance that software provides for service depends on how you
perform the system IPL. The service tools and functions that are available depend
on how you access DST and which operating system is in use. Service
environments for the system are:
v Stand-alone (also called non-paging)
v Limited paging
v Full paging
Stand-alone paging (non-paging)
You can reach this environment only by performing an alternate IPL to DST (see
“Performing an alternate IPL to DST (type D IPL)” on page 8).
You can access dedicated service tools (DST) while the system is in the stand-alone
paging environment, but not all DST options are available. In this environment, no
operating system is available, and only some functions of Licensed Internal Code
are operational.
The following options are available in the stand-alone environment for all
operating systems:
v Install Licensed Internal Code
v Work with disk units
v Work with DST environment
v Start a service tool
v Work with remote service support
For a description of each option, see “DST options” on page 10.
Attention: Performing an IPL on the primary partition will cause an IPL of all
secondary partitions.
Limited paging
You can reach this environment by performing an IPL to DST (see “Performing an
IPL to DST” on page 4).
The limited paging environment is the first servicing environment you access when
you start to bring up the system in Manual mode. This environment contains all
the functions of the Licensed Internal Code, including storage management.
2 Service Functions V5R2
You can access dedicated service tools (DST) while the system is in the limited
paging environment. This environment accesses the temporary files that are needed
and the Licensed Internal Code on the load-source disk. The operating system is
not available.
Attention: For systems with multiple logical partitions, performing an IPL on the
primary partition causes the secondary partitions to be powered down. Failing to
power down these secondary partitions will cause an abnormal power-down on
the secondary partitions and possible loss of data.
The following options are available in the limited paging environment for all
operating systems:
v Perform an IPL
v Install the operating system
v Work with Licensed Internal Code
v Work with disk units
v Work with DST environment
v Start a service tool
v Work with remote service support
v Work with system partitions
v Work with system capacity
v Work with system security
Note: The following options are operating system-dependent. For a list of the
v Perform automatic installation of the operating system
v Save Licensed Internal Code
v Select DST console mode
v Work with save storage and restore storage
For a description of each option, see “DST options” on page 10.
Attention: For systems with logical partitions, performing an IPL on the primary
partition causes the secondary partitions to be powered down. Failing to power
down these secondary partitions will cause an abnormal power down on the
secondary partitions and possible loss of data.
Full paging
The full paging environment is used during normal system operation. The DST
options vary depending on the release level of the operating system. You remain in
this environment when you perform one of the following:
v Function 21 on the control panel or “Work with Partition Status” screen to access
DST (see “Accessing Dedicated Service Tools” on page 4)
This is available only from the primary partition.
v System Request key procedure (see “Accessing Dedicated Service Tools” on
page 4)
v Access system service tools (SST) on a system that uses OS/400
system service tools” on page 282)

option from the Use Dedicated Service Tools (DST) display. For more information
on Licensed Internal Code fixes and PTFs, see “Licensed Internal Code (LIC)
introduction” on page 223 and the system operation information.
Licensed Internal Code general information
There can be two versions of some Licensed Internal Code modules on the
load-source disk unit. The IPL type (A or B) determines which version of the
modules your system uses. When the system is running on a type A IPL, it uses
the original, permanent version. When a Licensed Internal Code fix (or program
temporary fix (PTF)) is temporarily applied, the system creates a second version of
the module. The system uses this second version when it is running on a type B
IPL.
When the PTF is permanently applied, the side B of the LIC replaces the original
side A version of the LIC module. The system will then use the PTF version of the
LIC module (which is now permanent) when running on a type A IPL.
For PTFs to be activated on each partition, they must be separately applied to each
partition.
To apply a PTF that currently has an earlier version applied temporarily on the
system, be sure you IPL the system from the B side (type B IPL). Then load and
apply the PTF. The existing temporarily applied PTF automatically becomes
permanent as the new PTF is loaded. If you do not want the existing temporarily
applied PTF to become permanent, remove it manually (see the system operation
information).
If you perform the IPL on the B side when you apply PTFs to Licensed Internal
Code, the system applies the PTFs to the active copy of the Licensed Internal Code.
To run the system with the PTFs, you must perform an IPL. For normal operations
use type B IPL. Use type A IPL when the B side is not available or when you want
to remove a PTF.
Note: During and install or upgrade a type A IPL will also be used.
