Symptom-to-FRU Index
This index supports Type 3523 Fibre Channel Hub and
GBICs.
The Sympton-to-FRU lists symptoms, error, and the
possible causes. The most likely cause is listed first.
Note
Always start with the “General Checkout” on page 3.
For IBM devices not supported by this index, refer to
the manual for that device.
Note
Do Not look directly into any fiber cable or GBIC
optical output. Read “Safety Information” on page 51.
To view an optical signal, use a mirror to view the
reflected light.
Problem
FRU/Action
GBIC installed in one or
more ports but no LED is lit.
1. Power cord
2. Power source
GBIC installed but only the
amber LED is lit.
1. Reseat GBIC
2. GBIC
GBIC installed and both
green and amber LEDs are
lit.
The hub is not receiving a
valid Fibre Channel signal
from the end node. Do
the following:
1. Unplug the fiber cable
from the node and,
using a mirror, verify
that an optical signal is
present on the cable
receiver lead. If no red
light is visible, replace
the cable.
2. Using a mirror,
examine the SC
connectors on the HBA
or disk controller. If no
red light is visible on
the transmitter lead, do
one of the following:
a. Restart the
device.
b. Reinstall the
device drivers.
c. Check the HBA or
disk controller.
3. If a light is present on
both the cable lead
and the end node,
check the HBA or the
disk controller.
