transmit/receive activity light is off, make sure that the hub and network are
operating and that the correct device drivers are installed.
v
Check the LAN activity LEDs on the rear of the server. The LAN activity LED is lit
when data is active on the Ethernet network. If the LAN activity LED is off, make
sure that the hub and network are operating and that the correct device drivers
are installed.
v
Check for operating-system-specific causes of the problem.
v Make sure that the device drivers on the client and server are using the same
protocol.
If the Ethernet controller still cannot connect to the network but the hardware
appears to be working, the network administrator must investigate other possible
causes of the error.
Solving undetermined problems
If the diagnostic tests did not diagnose the failure or if the server is inoperative, use
the information in this section.
If you suspect that a software problem is causing failures (continuous or
intermittent), see “Software problems” on page 89.
Damaged data in CMOS memory or damaged IBM System x Server Firmware can
cause undetermined problems. To reset the CMOS data, use the password switch 2
(SW4) to override the power-on password and clear the CMOS memory; see
“Internal LEDs, connectors, and jumpers” on page 15.
Check the LEDs on all the power supplies (see “Power-supply LEDs” on page 96).
If the LEDs indicate that the power supplies are working correctly, complete the
following steps:
1. Turn off the server.
2. Make sure that the server is cabled correctly.
3. Remove or disconnect the following devices, one at a time, until you find the
failure. Turn on the server and reconfigure it each time.
v
Any external devices.
v
Surge-suppressor device (on the server).
v
Modem, printer, mouse, and non-IBM devices.
v
Each adapter.
v
Hard disk drives.
Note: If you install a ServeRAID-M1015 SAS/SATA adapter, make sure at
least 2 GB of memory is installed in the server before you run DSA from a
bootable CD.
The following minimum configuration is required for the server to start:
v One microprocessor
v One 1 GB DIMM
Note: If you install a ServeRAID-M1015 SAS/SATA adapter, make sure at least 2
GB of memory is installed in the server before you run DSA from a bootable CD.
v One power supply
v Power cord
v ServeRAID SAS adapter
v System board assembly
4. Turn on the server. If the problem remains, suspect the following components in
the following order:
