↓
Go to step 71 of this procedure.
69. Exchange the HSL Cable (see "SIRGCBL" on page 588).
70. Is the leading port status of the HSL link from the first failing resource
"failed"?
Yes No
↓
The link is now functioning. Go to step 79 on page 298 of this
procedure.
71. Exchange the Network interface controller (NIC) on the system unit (see
"SICNTRL" on page 584). Then go to step 79 on page 298 of this procedure.
72. Is the HSL cable an optical HSL cable?
Yes No
↓
Go to step 74 of this procedure.
73. Examine the state of the LEDs associated with the optical ports where the
HSL cable connections are by performing the following: Determine which
LEDs to examine using the 13 table.
Examine both LEDs at the ports for each end of the optical cable. Are all four
(4) LEDs lighted?
No Yes
↓
Go to step 76 of this procedure.
74. Exchange the HSL cable between the first failing resource and the second
failing resource using symbolic FRU "SIRGCBL" on page 588. Exchange only
the frame to frame cable. Do not exchange any internal HSL cables at this
time.
75. Is the leading port status of the HSL link from the first failing resource
"failed"?
Yes No
↓
The link is now functioning. Go to step 79 on page 298 of this
procedure.
76. Determine which FRU on the second failing resource to exchange using the
following table.
If the HSL trailing port on the second
failing resource is:
Port A0
Ports B0, C0, D0, E0, F0, G0, H0
Ports A1, B1, C1, D1, E1, F1, G1, H1
Chapter 3. Problem Isolation Procedures (PIPs), Failing Items, and Symbolic FRU Isolation
Bus, High-Speed Link (HSL) PIPs
Exchange this FRU on the frame with the
second failing resource:
HSL I/O Bridge using symbolic FRU
"SIIOADP" in the Problem Analysis, Parts
and Repair document that supports that
system unit and model. In this document see
"SIIOADP" on page 585.
Network Interface Controller (NIC) using
symbolic FRU "SICNTRL" in the Problem
Analysis, Parts and Repair document that
supports that system unit and model. In this
document see "SICNTRL" on page 584.
Network Interface Controller (NIC) using
symbolic FRU "SICNTRL" in the Problem
Analysis, Parts and Repair document that
supports that system unit and model. In this
document see "SICNTRL" on page 584.
