If you are accessing the compute node from a remote location, complete the following steps:
1. Make sure that all applications are running (no applications are hung).
2. Attempt to log out of the compute node and log back in.
3. Validate the network access by pinging or running a trace route to the compute node from a command
line.
a. If you are unable to get a response during a ping test, attempt to ping another compute node in the
chassis to determine whether it is a connection problem or compute node problem.
b. Run a trace route to determine where the connection breaks down. Attempt to resolve a connection
issue with either the VPN or the point at which the connection breaks down.
4. Restart the compute node remotely through the management interface.
5. If the problem remains make sure that any new software has been installed and configured correctly.
6. Contact your place of purchase of the software or your software provider.
Unusual smell
An unusual smell might be coming from newly installed equipment. If the problem remains, contact Support.
Compute node seems to be running hot
Complete the following steps until the problem is solved.
Multiple compute nodes or chassis:
1. Make sure that the room temperature is within the specified range (see “Features and specifications”
on page 5).
2. Check the Flex System Manager management software or CMM event log for rising temperature events.
If there are no events, the compute node is running within normal operating temperatures. Note that
you can expect some variation in temperature.
Single compute node:
Check the Flex System Manager management software or CMM event log for rising temperature events. If
there are no events, the compute node is running within normal operating temperatures. Note that you can
expect some variation in temperature.
Cracked parts or cracked chassis
Contact Support.
Optional device and replaceable component installation problems
Use this information to solve optional device and replaceable component installation problems.
External USB device not recognized
Complete the following steps until the problem is solved:
1. Make sure that the correct device drivers are installed in the compute node. See the product
documentation for the USB device for information about device drivers.
2. Use the Setup utility to make sure that the device is configured correctly.
3. If the USB device is connected to a hub or the console breakout cable, disconnect the device and
connect it directly to the USB port on the front of the compute node.
4. Run the DSA USB diagnostic tests
