Network Interface Card (embedded or PCI) Problems
If the HP Server cannot connect to the network and all the LEDs are lit on the NIC:
1. Verify that there are no resource conflicts between the NIC and any other accessory. Do this from the
system BIOS Setup Utility (<F2> on POST when prompted).
2. Reboot the HP Server and log into the NOS.
3. Ensure the latest and correct HP drivers are being used for the NIC.
4. Ensure the port on the switch or hub (or other device) has the same speed and duplex settings as on the
NIC.
CAUTION Setting an incorrect duplex mode can degrade performance, cause data loss, or result in
lost connections.
5. Test the NIC as directed in the installation tasks for each NOS. This information is in the HP Server’s
Installation Manual. Also check the README files on the support driver’s disk.
6. Use the PING command to verify TCP/IP configuration.
a. Ping the IP address of the default gateway. If the PING command fails, verify that the default
gateway IP address is correct and that the gateway (router) is operational.
b. Ping the IP address of a remote host (a host that is on a different subnet). If the PING command fails,
verify that the remote host IP address is correct, that the remote host is operational, and that all of the
gateways (routers) between this computer and the remote host are operational.
7. Directly connect two devices (with no hub, switch, or other device) using a “crossover” cable. PING
the other computer’s IP address.
NOTE The PING command uses Internet Control Message Protocol (ICMP) Echo Request and
Echo Reply messages. Packet filtering policies on routers, firewalls, or other types of
security gateways might prevent the forwarding of this traffic.
LEDs are not lit on the NIC
No lit LEDs probably indicates a bad network cable, hub connection, or other network error.
1. Ensure that the cabling is installed correctly:
a. Try another known good network cable.
b. Try another network connection (another hub, switch, etc.)
c. Connect the NIC to a known good network connection.
If there are still no lit LEDs, do the following:
2. Power off the HP Server and unplug the power cord/s from the power source. Remove the left side
cover.
NOTE The HP Server tc3100 has an integrated NIC so skip the following steps unless a PCI NIC
is installed in the server.
CAUTION Always wear an antistatic wrist guard when working inside the HP Server.
3. Locate the NIC and reseat it in its slot.
4. Replace the covers; plug in the power cord/s to a power source, and power on the HP Server.
