Laser Safety Information
Note: The Optical Link Card (OLC) referred to in this information is part of the Serial Optic
Channel Converter assembly.
This system contains a laser product called the Optical Link Card (OLC). In the U.S., the
OLC 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 OLC is certified as a Class 1 laser product that conforms to the
requirements contained in the International Electrotechnical Commission (IEC) standard 825
(1984), the Verband Deutscher Elektrotechniker (VDE) standard 0837 (1986), and the
CENELEC (European Committee for Electrotechnical Standardization) Harmonization
Document HD 482 S1 (1988). The German testing institute VDE assigned a certificate of
conformity to DIN IEC 825/VDE 0837/02.86 and CENELEC HD 482 S1/03.88; the certificate
registration number is 3642.
In addition, Statens Provningsanstalt (Swedish National Testing Institute) tested and
approved the OLC for use in Sweden as a Class 1 laser product and assigned the approval
number SP LA 89:184. The CDRH certification label and the VDE certificate of conformity
mark are located on the plastic retainer of the OLC product. Figure 1 shows the system
Class 1 information label required by IEC 825.
Class 1 laser products are not considered to be hazardous. The OLC internally contains a
gallium aluminum arsenide (GaAlAs) semiconductor laser diode emitting in the wavelength
range of 770 to 800 nanometers. This laser diode is a Class 3B laser that is rated at 5.0
milliwatts. The design of the OLC is such that access to laser radiation above a Class 1
level during operation, user maintenance, or service conditions is prevented.

Note: For a translation of this notice, see
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the products that attach to the system. It is
the responsibility of the customer to ensure that the outlet is correctly wired
and grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables for the
system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system, ensure
that the power cables for those devices are unplugged before the signal cables
are connected. If possible, disconnect all power cables from the existing system
before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to prevent
a possible shock from touching two surfaces with different electrical potentials.
During an electrical storm, do not connect cables for display stations, printers,
telephones, or station protectors for communication lines.
CAUTION:
This product is equipped with a three-wire power cable and plug for the user’s
safety. Use this power cable in conjunction with a properly grounded electrical outlet
to avoid electrical shock.

Step 4
(from Step 3)
This problem can be caused by one of the following FRUs:
• Front fan
• Rear fan
Note: It is likely that the voltage regulator has failed when power is supplied and the power
light is on for one second or less. The same symptom will occur when the voltage
regulator is not connected to the CPU card.
• Voltage regulator card (Model 39H)
• System planar (Models 340, 34H, 350, 355, 360/36T, 365, 370/37T, and 375 , 380, 390,
397 if the rear fan is failing)
• Power supply.
The power supply will not stay on if it does not sense the rotation of the cooling fans.
Note: The power supply does not sense the fans that cool the disk drives if the fans have
only two wires and comes on independent of the operation of the front or rear fans.
These fans will not cause the power supply to shutdown.
When the front or rear fans are not connected or are not operating, the power supply
will usually power on for approximately three seconds before shutting down.
1. Set the power switch on the system unit to Off.
2. Test each fan by connecting a new fan. Refer to the “Rear Fan” removal procedure on
page 3-45 and the “Front Fan” removal procedure on page 3-46.

The failure may be caused by a defective SIMM on the last memory card installed. To
isolate the failing SIMM in a pair of SIMMs, do the following:
1. Set the power switch on the system unit to Off. Using a pair of operational SIMMs for the
type of memory card used, install the pair of SIMMs in locations 1 and 2 on one of the
suspected memory cards.
2. Set the power switch on the system unit to On. If operational, the system will stop and
two or more numbers with values between 221 and 296 are displayed alternately in the
three-digit display, or a solid 262 will be displayed.

Removal and Replacement Procedures3-1
Handling Static-Sensitive Devices
Attention: Adapters, planars, diskette drives, and disk drives are sensitive to static
electricity discharge. These devices are wrapped in antistatic bags, as shown in this
illustration, to prevent this damage.
Take the following precautions:
• Do not remove the device from the antistatic bag until you are ready to install the device
in the system unit.
• If you have an antistatic wrist strap available, use it while handling the device.
• With the device still in its antistatic bag, touch it to a metal frame of the system.
• Grasp cards and boards by the edges. Hold drives by the frame. Avoid touching the
solder joints or pins.
• If you need to lay the device down while it is out of the antistatic bag, lay it on the
antistatic bag. Before you pick it up again, touch the antistatic bag and the metal frame of
the system at the same time.
• Handle the devices carefully in order to prevent permanent damage.
