Follow the steps in the order indicated below. If an action resolves the issue, retest the 
computer to verify. If the issue persists after retesting, return to step 1.
Ethernet Port/Device Issue
Unlikely cause: power supply, fans, speaker, optical drives, hard drives, processor board, front 
panel board, memory
Quick Check
SymptomQuick Check
Ethernet Port/Device Issue
• One or both Ethernet ports 
may not function
• No Ethernet device present
• Unable to access network 
resources
• Ethernet device shows no 
connection
• Ethernet device unable to get 
an IP address
• Slow network performance
1. Check the network cable for damage, try a 
known good Ethernet cable – CAT5 or better 
recommended for 100Mbps+ connections.
2.  Check both Ethernet ports on Mac and wall/
switch for dust, debris, damage or bent pins. 
3. Ensure distance from networking infrastructure is 
less than 300 feet / 105 meters. 
4.  Verify both Ethernet ports, cable and network 
hardware with a known good computer. Isolate 
firewall, MAC address filtering or hardware access 
control devices.
5. Check system logs. Isolate OS by starting up 
from original install media (10.6.x) or compatible 
known good OS.

1. Visually inspect Ethernet 
connector to ensure all pins 
will make physical contact with 
Cat5 network cable.
YesEthernet interface contacts 
are good to go. Go to step 2.
NoPins are damaged or bent flat, 
replace backplane board.

2. Isolate OS by booting from 
original install media. Verify 
Network Link status active by 
using Network Utility on install 
DVD.   If the ethernet interface 
(en0 or en1) Link Status is 
inactive, recheck physical 
connect and link activity 
indicator on hub/switch.
YesEthernet interface (en0 or 
en1) Link Status is active, go 
to step 3.
NoIf connection is ok on known 
good computer, replace 
backplane board. 
M10
3. Verify if IP address is listed 
for the ethernet interface in 
System Preferences: Network. 
Connect computer to network 
with known good DHCP IP 
allocation, ensuring static 
DHCP maps or filtering is not 
preventing address allocation.  
Note: DHCP allocation may not 
be instantaneous depending 
on network. Retest.
Yesgo to step 4
NoIf connection is OK on known 
good computer, replace 
backplane board.
M10
4.  Verify connection by using 
Network Utility to ping another 
connected computer on the 
same subnet.   Ensure the 
target computer’s IP address is 
valid, on the same subnet and 
powered on. Ensure no MAC 
address filtering or hardware 
access control devices are 
present. Use a simple Hub/
Switch environment.
YesGo to step 5
NoIf the symptoms do not 
change, replace the 
backplane board.
M10
5. Verify ethernet performance 
and reliability by booting from 
a known good OS install, and 
downloading a large file from a 
web site or file server. 
YesIf you cannot isolate the 
performance or connectivity 
issue to the computer under 
test, the problem may be the 
network environment. No 
repair is necessary. 
NoIf there are connection 
dropouts or poor 
performance not seen on a 
known good test computer, 
replace the backplane board.
