System Reference Codes
This topic uses a System reference code on the problem summary form to:
v Find a list of possible failing items.
v Point to additional isolation procedures (if available).
System reference codes (SRCs) can appear on the control panel, the product
activity log (PAL), the Main Storage Dump Manager display, or on various
displays within DST or SST.
1. Were you directed here from another procedure, including the Starting point for
all problems?
v No: Go to the Starting point for all problems.
v Ye s: Determine which SRC table to use.
For SRCs appearing on the control panel, the first 4 characters represent the
SRC type and the second 4 characters represent the URC. For SRCs
appearing in the Product Activity Log or on other software displays, use
characters 1 through 4 of word 1 for the SRC type and characters 5 through 8
of word 1 for the URC.
The SRC table name is the same as the SRC type. For SRCs appearing on the
control panel, the SRC type is the first 4 characters (see Figure 1 on page 2 for
control panel layout). For SRCs appearing in the Product Activity Log or on
other software displays, use characters 1 through 4 of word 1 for the SRC
type. The reference code tables only support 8-character SRC formats. If the
SRC provided is in a 4 character format, contact your next level of support
for assistance.
You will also need to know what the unit reference code (URC) is. For SRCs
appearing on the control panel, the URC is the second 4 characters of the
SRC (see Figure 1 on page 2 for control panel layout). For SRCs appearing in
the Product Activity Log or on other software displays, use characters 5
through 8 of word 1 for the URC. The URCs are listed within the SRC tables,
arranged in hexadecimal sequence with numeric characters listed before
alphabetic characters. For example, URCs 0001 through 0009 are listed before
URCs 000A through 000F.
For additional information about using the Control Panel, see SRC address
formats.
Continue with the next step for instructions on finding and using the SRC
tables.
2. Links to all of the SRC tables can be found in the System reference code list.
Once you find the correct SRC table, correct the problem by performing the
action indicated for the URC in the Description/Action column of the table. If
this does not correct the problem, exchange the failing items or parts listed in
the Failing Item column in the order that they are listed.
If no action is indicated in the SRC table, exchange the failing items or parts
listed in the table.
Notes:
a. When exchanging the failing items, use the Remove and replace procedures.
b. When instructed to perform problem isolation procedures, go to the
Problem isolation procedures.
c. Any additional information you need to complete the procedure, may be
found in the Part locations and listings.
The failing item listed first should be exchanged first. If exchanging the first
failing item does not correct the problem, reinstall the original item and
exchange the next failing item listed. Continue to exchange and reinstall the
failing items, one at a time, until the problem is corrected. If exchanging the
failing items does not correct the problem, ask your next level of support for
assistance.
Now refer to the System reference code list and follow the instructions in the
SRC table. The list contains all SRC tables for critical resources available at the
time this edition was published. If you cannot find an SRC table, ask your next
level of support for assistance.
This ends the procedure.
Refer to the System reference code list for more information.
Safety and Environmental Notices
Danger Notices
A danger notice calls attention to a situation that is potentially lethal or extremely
hazardous to people.
Use the following danger notices throughout this book:
DANGER
To prevent a possible electrical shock during an electrical storm, do not
connect or disconnect cables or station protectors for communications lines,
display stations, printers, or telephones. (RSFTD003)
DANGER
To prevent a possible electrical shock from touching two surfaces with
different electrical grounds, use one hand, when possible, to connect or
disconnect signal cables. (RSFTD004)
DANGER
To prevent a possible electrical shock, do not use the port tester during
electrical storms. (RSFTD006)
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
customer’s responsibility to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock. (RSFTD201)
DANGER
To prevent a possible electrical shock when installing the system, ensure that
the power cords for all devices are unplugged before installing signal cables.
(RSFTD202)
System Reference Codes3
DANGER
To prevent a possible electrical shock when adding or removing any devices
to or from the system, ensure that the power cords for those devices are
unplugged before the signal cables are connected or disconnected. If possible,
disconnect all power cords from the existing system before you add or
remove a device. (RSFTD203)
DANGER
To prevent power from switching on automatically during service procedures,
select manual or secure mode on the system unit control panel or disconnect
the cables that connect to J15 and J16 on the frame being serviced.

DANGER
Use caution when installing or modifying telephone lines. Disconnect the
lines at the network interface before working with telephone wires that are
not insulated. Never install telephone jacks that are not waterproof in wet
locations. Do not install or modify telephone lines or use a telephone (other
than a cordless type) during an electrical storm. Do not use a telephone to
report a gas leak in the area of the leak. (RSFTD213)
