2. Perform a slow IPL. Then, check the Service Action Log and work any errors found during the
extended IPL diagnostics.
3. If, after servicing any other processor reported errors, the B4xx xEBF error persists, contact your next
level of support.
This ends the procedure.

One end of the failed link is a system unit other than the one reporting this error. In a cluster, all system
units should send a warning to the other system units in the cluster when they are about to perform a
controlled power down. This error could occur when a system unit leaves the cluster without issuing any
warning to other system units. If the system unit is not reporting due to a failed cable or HSL hardware,
replacing the FRUs in this error log entry will correct the problem.
However, the system unit may have been powered down immediately, or powered down because of an
error. If this is the case, work any errors in the other system unit, or power the other system unit back on.
When the other system unit reports in, the loop will be complete and this error can be closed.

A problem has occurred in a remote system that is in an HSL OptiConnect loop. The Service Action Log
(SAL) code will attempt to identify the HSL loop number of the local system and the serial number of the
remote system as a portion of the part description for this symbolic FRU. If the SAL could not identify the
serial number of the remote system then check all the systems which are connected to the local HSL loop
identified in the SAL. Search the SAL of the remote system(s) for hardware and LIC problems. Correct any
problems you find with LIC or Network Interface Controller (NIC) hardware.

Follow the instructions for the model you are working on:
v Models 270, 820, 830, 840, SB2, or SB3 (See page 444)
v Models 800, 810, 825, 870, or 890 (See page 444)
Instructions for Models 270, 820, 830, 840, SB2, and SB3
The system processor has detected an error on the HSL port.
1. Use the information in the Description/Action column of the following System reference code tables:
B427 (for Models 270 and 820), and B437 (for Models 830 and SB2), and B467 (for Models 840 and
SB3), and the information from Locations and addresses to determine the physical mapping of the
information from the Location column.
2. Check the cabling and connections from the failing item location. Then, follow the procedure in
symbolic FRU "SIRGCBL" on page 453.
This ends the procedure.
