3210 An HSL link switched to a slower speed. The link is designed to run at a
faster speed. Exchange the HSL I/O bridge.
Indicated status for PRC in Word 4, 3209:
Recoverable CRC errors have occurred on the loop. This error requires a service
action.
An HSL cable or connection must be exchanged. Exchange only the HSL
cable that appears in the FRU list of this SRC (SIRGCBL) in this document. If you
are working from the SAL, then only the FRU(s) required for this error will be
displayed.
1. If you are working with a Service Action Log (SAL) entry then perform the
following, otherwise go to step 2 of this procedure.
v
If the SAL entry has cable FRU(s) ( SIRGCBL in the part number field)
listed with a loop number, frame ID and port label identified with the cable
FRU, then go to step 8 of this procedure.
v
If the SAL entry has cable FRU(s) ( SIRGCBL in the part number field), but
the loop number, frame ID, and port label are not all listed with the cable
FRU, then go to step 2 of this procedure.
v
If the SAL entry does not list any cable FRUs (SIRGCBL is not in the part
number field), then exchange the failing items listed in the SAL entry by
following the normal service procedures for those FRUs.
This ends the procedure.
2. Perform the following steps to determine the loop number, frame ID and the
port label where the CRC errors have been detected. As you follow the steps,
record the information on the “Appendix I. HSL Cable Location Form” on
page 971.
3. Examine word 7 of the SRC. The loop number is the leftmost four digits of
word 7 in the SRC. The loop number is displayed in hexadecimal format.
Convert the bus number to decimal format, (as it is shown in HSM) using the
Table 7 on page 281. Record both the hexadecimal loop number and the
decimal loop number in the “Appendix I. HSL Cable Location Form” on
page 971. If the loop is an internal loop on a model 270 then record

on the worksheet.
4. Examine word 5 of the SRC. The frame ID is the leftmost four digits of word
5 in the SRC. The frame ID is displayed in hexadecimal format. You must
convert the frame ID to decimal format to match what is displayed on the Op
Panel of that frame. Record the both the hexadecimal and decimal frame IDs
in the “Appendix I. HSL Cable Location Form” on page 971 as the

.
Note: A frame ID of 0000 is valid at this point in the procedure.
5. Is the frame ID 0000 -OR- (is the frame ID 0001 and is the system a model
270)?
Yes No
↓
Go to step 7 of this procedure.
6. Frame ID zero 0000 indicates the Network Interface Controller. Use the Loop
