Solving Undetermined Problems - IBM System x3350 Type 4192 Problem Determination And Service Manual

v Check the Ethernet activity LED on the rear of the server. The Ethernet activity
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
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 145.
Damaged data in CMOS memory or damaged BIOS code can cause undetermined
problems. To reset the CMOS data, use the clear CMOS jumper to clear the CMOS
memory and override the power-on password; see "System-board switches and
jumpers" on page 10. If you suspect that the BIOS code is damaged, see
"Recovering from a BIOS update failure" on page 213.
Check the LEDs on all the power supplies (see "Power-supply LEDs" on page 151).
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

– The Ethernet link status LED is lit when the Ethernet controller receives a link
pulse from the hub. If the LED is off, there might be a defective connector or
cable or a problem with the hub.
– The Ethernet transmit/receive activity LED is lit 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 installed.
