10. Turn off the server.
11. Remove the jumper on the boot-block jumper block or move it to pins 1 and 2
12. Restart the server. The system should start up normally.
Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the 10/100 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the network, check the following:
v Make sure that the cable is installed correctly.
v Determine if the hub supports auto-negotiation. If not, try configuring the
v Check the Ethernet controller lights on the operator information panel.
v Make sure that you are using the correct device drivers, supplied with the server.
v Check for operating system-specific causes for the problem.
v Make sure that the device drivers on the client and server are using the same
v Test the Ethernet controller.
6. The system completes the power-on self-test (POST). Select 1 – Update
POST/BIOS from the menu that contains various flash (update) options.
7. When you are asked if you would like to move the current POST/BIOS image
to the backup ROM location, type N.
Attention:
Typing Y will copy the corrupted BIOS into the secondary page.
8. When you are asked if you would like to save the current code to a diskette,
select N.
9. You will be asked to choose which language you wish to use. Select your
language (0-7) and press Enter to accept your choice. You will be prompted to
remove the diskette and press Enter to restart the system. Remove the flash
diskette from the diskette drive.
to return to normal startup mode.
The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use Category
5 cabling.
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the
label contains an X, the hub has an X port.
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
These lights indicate whether a problem exists with the connector, cable, or hub.
– The Ethernet Link Status light illuminates when the Ethernet controller
receives a LINK pulse from the hub. If the light is off, there might be a bad
connector or cable, or a problem with the hub.
– The Ethernet Transmit/Receive Activity light illuminates when the Ethernet
controller sends or receives data over the Ethernet Network. If the Ethernet
Transmit/Receive Activity light is off, make sure that the hub and network are
operating and that the correct device drivers are loaded.
– The Ethernet Speed 100 Mbps light illuminates when the Ethernet controller
LAN speed is 100 Mbps.
