a network
port.
Issue 20 (2020-09-25)
Diagnosis Procedure
1. Check whether the network
cable is connected properly to
the network port.
2. Use the Computing Product
Compatibility Checker
check whether the NIC type is
compatible with the server
board. Use Computing
Product Firmware and Driver
Mapping Checker
whether the NIC firmware and
driver versions match the OS.
If they do not match, upgrade
the NIC firmware and driver
first.
3. To check whether the network
ports are up, run the ifconfig
N up command in Linux
eth
(the command may vary in
different OSs). To check
whether IP addresses are set
for the required network ports,
run the ethtool eth
command.
4. Run the ethtool -p eth
command in Linux (the
command may vary in other
OSs) to check whether the
information in the network
port configuration file of the
rack server/Atlas 800 AI
inference server (model 3010)/
Atlas 800 AI training server
(model 9010) is consistent
with the actual physical
network ports, and check
whether the network port
status indicators are on and
whether the network ports on
the switch are up.
NOTE
The ethtool -p eth
applies only to plug-in PCIe cards.
5. Check the network port
configuration of the switch
module by referring to

check whether the server or
other servers on the
network have network
faults.

2. Check the indicator to see
the NIC port status. If the
indicator is off, switch the
optical module, optical
cable, and uplink switch
port related to the faulty
NIC port with those of a
normal NIC port if any of
these components are
faulty. Then replace them.

when interruption will not
affect services, and check
whether the communication

persists, power the server
off and on. If the fault still
persists, replace the NIC.
