screen for the first failing resource.
53. For the first failing resource, did the failing port number change?
No Yes
↓
Exchange the HSL I/O Bridge in the frame of the first failing resource
(see “SIIOADP” on page 585). Then go to step 79 on page 298 of this
procedure.
54. Is the HSL cable an optical HSL cable?
Yes No
↓
Go to step 56 of this procedure.
55.
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 table below.
Table 13. LED Locations
Frame type LED locations
FC 5074, 5078/0578 LEDs are located on the HSL I/O Bridge
card directly below the optical ports for the
HSL cable. There is one (1) LED associated
with each port and they are labeled as
x -1L,
x -2L, y -1L, y -2L, where x and y are the port
numbers.
Models 830/SB2 LEDs are located in pairs directly below the
optical ports for the HSL cable. There is one
(1) LED associated with each port and they
are labeled as
B0-1L , B0-2L , B1-1L , B1-2L .
See Figure 33 on page 717.
Models 840/SB3 LEDs are located in pairs either above or
below the optical ports. The two (2) LEDs
closest to (above or below) the optical port
pair for the cable belong to that port pair.
There is one (1) LED associated with each
port and they are labeled as
x -1L, x -2L, y -1L,
y -2L, where x equal D0 or E0 and y equals
D1 or E1.
See Figure 40 on page 733.
Examine both LEDs at the ports for each end of the optical cable. Are all four
(4) LEDs lighted?
No Yes
↓
Go to step 58 of this procedure.
56. Exchange the HSL cable (see “SIRGCBL” on page 588).
57. 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.
58. Exchange these FRUs in the following order:
Bus, High-Speed Link (HSL) PIPs
