Troubleshooting

Troubleshooting General/ - 1
General
The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)
For additional assistance, contact Apple Technical Support.

Symptom Charts
EtherTalk Cards
EtherTalk icon missing
from Network extension
in Control Panel
Two or more EtherTalk
icons appear in Network
extension in Control
Panel
1 Switch off computer and reseat card.
2 EtherTalk software is not installed properly on current
startup disk. Reinstall EtherTalk software.
3 Replace EtherTalk card.
Earlier versions of EtherTalk are on your startup disk. Remove
earlier versions.

EtherTalk icon missing
on startup
Network service
(servers, printers, etc.)
missing from Chooser
Can’t change network
connection
1 Switch off computer and reseat card.
2 EtherTalk software is not installed properly on current
startup disk. Reinstall EtherTalk software.
3 System software is damaged. Reinstall system software.
4 Replace EtherTalk card.
1 Check service zones.
2 Versions of EtherTalk software on system and on network
don’t match. Network and system must both be using
EtherTalk Phase II to work properly.
3 Check cables and connections.
1 Currently selected network is providing service that
computer is using.
2 Computer is providing service that network is using.

1 Verify Ethernet LC Card has updated ROM (part number
341-0470).

Troubleshooting Symptom Charts/Apple PCI Ethernet 100BASE-TX Card - 6
Apple PCI Ethernet 100BASE-TX Card
Can’t access network
from host machine or
data is not being
transmitted
1 Check to be sure the network cable is attached securely to the
Ethernet port on the card.
2 Check the LEDs on the card, which are visible from the
server’s rear panel. The green LED should be lit, indicating
you are connected to a 100BASE-TX network and a valid
MLT-3 signal is being received from the network. The
yellow LED should blink when data is being transmitted or
received.
3 If the green LED is not lit, verify you are connected to a valid
(IEEE 802.3u-compatible) 100BASE-TX network.
4 Verify the driver setup. Refer to the Network Server
installation manual for instructions.
5 Verify the PCI Ethernet card is installed properly. Reseat the
card if necessary.
6 Replace the PCI Ethernet card with a known-good card.

Apple PCI Ethernet Card
Can’t access network
from host machine or
data is not being
transmitted
1 Check to be sure the network cable is attached securely to the
Ethernet port on the card.
2 Remove the top housing from the server and check the LEDs
on the PCI Ethernet card.
• The green LED should be lit if you are connected to a
network via the 10Base-T connector.
• The amber LED should be lit if you are connected to a
network via the AAUI connector.
• The first yellow LED should be lit if you are connected to a
network via the BNC connector.
• The second yellow LED should blink when data is being
transmitted or received.
3 If the LED that is lit does not correspond to the cable attached
to the PCI Ethernet card, verify the driver setup. Refer to
the Network Server installation manual for instructions.

4 Verify the PCI Ethernet card is installed properly. Reseat the
card if necessary.
5 Replace the PCI Ethernet card with a known-good card.
Clicking sounds or
long pauses during
system booting
If you installed a PCI Ethernet card in a Network Server and
configured it by assigning it an IP address or enabling the
AppleTalk stack on it, the card attempts to determine which of
three possible media types is connected to it. The clicking will
continue until you attach network media (that is, until a cable is
attached to the card). Although this should cause no serious
problems, the lack of media may cause long pauses during system
booting, as the system attempts to contact other servers on the
network. For more information on installing cards and AIX
drivers, see Chapter 4 of the Setting Up the Network Server
manual.

No preliminary steps are
required before you begin
this procedure.
The Ethernet LC Upgrade
allows the original Ethernet
LC card to be used in the
Macintosh LC II.
The upgrade is required on
Ethernet LC cards (part
